Convert an AVCHD / MTS file to MP4 using ffmpeg
Convert an .MTS file to a .MP4 file
We want to convert it to .MP4, for instance to show it on a mobile device Android, or to play it om xbmc, or to import into kdenlive.
For a whole directory, type:
IFS=$(echo -en "\n\b"); for i in *.MTS; do ffmpeg -i "$i" -vcodec mpeg4 -b:v 15M -acodec libmp3lame -b:a 192k "$i.mp4"; done
or offtopic:
find . -print0 | while read -d $'\0' file do echo -v "$file" done
Now, if you want to resize it for some reason (show on mobile phone):
#ffmpeg -i 00031.MTS -s 480x320 -b:v 4000k 00031.MP4
-i = input file
-s = size <=== PUT THE SIZE PARAMETER JUST AFTER THE INPUTFILENAME, OTHERWISE YOU GET AN ERROR
-b:v = videobitrate, 8000k gives a slightly better image, but doubles the filesize -b:a = audiobitrate
Using these parameters you shrink a 25MB movie to a 6 MB movie.
Convert an .DV file to a .MP4 file
ffmpeg -i tape.dv -vcodec mpeg4 -b:v 15M -acodec libmp3lame -ab 192k -threads 2 -ilme tape.mp4
-ilme = Force interlacing support in encoder (MPEG-2 and MPEG-4 only). Use this option if your input file is interlaced and you want to keep the interlaced format for minimum losses. The alternative is to deinterlace the input stream with -deinterlace, but deinterlacing introduces losses.
Convert an .MTS file to a .DV file for video editing
We want to convert it to .DV, because then our video editing program (kdenlive) will process the clips much much faster!!!
#ffmpeg -i 00005.MTS -f avi -b:v 16000k -ab 192k 00005.DV
-i = input file
-f = format, appeared neccessary
-b:v = videobitrate, this value of 16000k is exactly the same as the source file, because we don't want any loss!!
-b:a = audio bitrate, this value of 192k is exactly the same as the source file, because we don't want any loss!!
ALTERNATIVE
I also found this commandline, worked very well:
ffmpeg-kino -threads 2 -i 00120.MTS -s 720x576 -r pal -aspect 16:9 -ac 2 -ar 48000 -pix_fmt yuv420p -y 00120.MTS.dv
Another commandline:
ffmpeg -y -i 00141.MTS -vcodec mpeg4 -b:v 8000000 -ab 128000 -s 1280x720 new2.mp4 ffmpeg -y -i 00101.MTS -vcodec mpeg4 -b:v 14M -acodec ac3 -ab 192k new.mp4 <-- deze gebruikt om .MTS in kdenlive te importeren
dus:
for i in *; do ffmpeg -y -i "$i" -vcodec mpeg4 -b:v 14M -acodec ac3 -ab 192k "$i".mp4; done
Convert to WebM (VP8)
A valid WebM file can only contain VP8 video and Vorbis audio in a .webm container.
ffmpeg -i bla.mp4 -vcodec libvpx -b:v 15M -acodec libvorbis -b:a 192k out.webm
For web page (reduced size):
# ffmpeg -i 44.mp4 -s 568x320 -vcodec libvpx -b:v 300k -acodec libvorbis -b:a 64k 44.webm
Convert an .MTS file to Flash (FLV)
ffmpeg -i bla.mts -s 640x360 -ar 22050 -b:v 1M blaat.flv
of pas de bitrate aan voor hogere kwaliteit:
ffmpeg -i bla.mts -s 640x360 -ar 22050 -b:v 3M blaat.flv
Convert an old analogue letterbox recording to SD digital format
The input file was
Input #0, mpeg, from '1106_20091226203000.mpg':
Duration: 04:24:55.20, start: 0.276144, bitrate: 6934 kb/s
Stream #0.0[0x1e0]: Video: mpeg2video (Main), yuv420p, 720x576 [PAR 64:45 DAR 16:9], 8000 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc
Stream #0.1[0x1c0]: Audio: mp2, 48000 Hz, stereo, s16, 384 kb/s
and the picture has big black borders on the top and bottom and looks squashed. It was supposed to be stretched to fill up the screen (Our old analogue TV did that automatically).
This must be done in 2 steps: first the cropping, then rescaling back to 16:9
The first command is
ffmpeg -i input.mpg -vf crop=720:430 -vcodec mpeg2video -b:v 8M -acodec mp2 -b:a 384k 25ycrop.mpg
Note that we try to keep the audio/video exactly the same as the sourcefile. The commandline options -sameq and -vcodec copy don't seem to work here.
Next we must scale the video back to full screen, again the same settings for vcodec and acodec:
ffmpeg -i 25ycrop.mpg -s 720x576 -aspect 16:9 -vcodec mpeg2video -b:v 8M -acodec mp2 -b:a 384k bla.mpg
Other examples
# ffmpeg -i 00039.MTS -f avi -vcodec mpeg4 -b:v 16000 bla.wmv
# ffmpeg -i 00039.MTS -f avi -vcodec msmpeg4v2 -b:v 16000 bla.wmv
# ffmpeg -y -i VIDEO0005.3gp -vcodec wmv2 -f avi -ar 44100 kerst2009.avi
# ffmpeg -formats -> lists formats
# ffmpeg -f avi -> force avi format
# ffmpeg -codecs -> lists codecs
# ffmpeg -vcodec mpeg4 -> use codec
# ffmpeg -acodec libmp3lame -> use mp3 audio codec
# ffmpeg -i <inputfile> -> show info about movie file
# ffmpeg -y -> overwrite outputfiles
# ffmpeg -vcodec copy -ss 00:01:00 -t 00:03:00 -i infile.mpg outfile.mpg -> this cut the file from 1 minute to 4 minutes (t=duration)
or
# ffmpeg -i inputfilename.mpg -sameq -ss 00:01:00 -t 00:03:00 outfile.mpg
The above will extract 3 minutes of mpg file from the 1 minute mark using same quality as the source file. This is useful for Variable Bit Rate (VBR) encoded files.
# ffmpeg -target dvd|vcd|svcd|dv|dv50 -> all options are set automagically, but you can overrule as long as they don't conflict w/ the standard
-r --> set framerate, default = 25. also 'pal' is accepted
-threads --> set thread count
# ffmpeg -i 00090.MTS -f avi -b 6000k -ab 192k -vcodec mpeg2video 00090.mpg
convert MTS to XBOX readable format
example command to preserve EXIF data and timestamps
$ for i in *.MOV ; do ffmpeg -i "$i" -preset slow -crf 27 "${i//.MOV}.mp4" ; exiftool -tagsFromFile "$i" "${i//.MOV}.mp4" ; touch -r "$i" "${i//.MOV}.mp4" ; done
!!I should have used ${i%.MOV}.mp4 to match only the suffix pattern, not anywhere in the variable string.
example of Intel Skylake 520 vaapi encoding
# ffmpeg -threads 4 -i dcc-basf.mp4 -vaapi_device /dev/dri/renderD128 -vcodec h264_vaapi -vf format='nv12|vaapi,hwupload' output2.mp4
Burning subtitles from embedded subtitles stream into the video image
# ffmpeg -i s01e01.mkv -c:v libx264 -c:a copy -vf "subtitles=s01e01.mkv:stream_index=1" output.mkv
where
stream_index is the # of the subtitle stream
This gives encoding fps of around 30.
ultrafast encoding:
# ffmpeg -i s01e01.mkv -c:v libx264 -preset ultrafast -c:a copy -vf "subtitles=s01e01.mkv:stream_index=1" output.mkv
This gives encoding fps of around 140.
Note:
The "ultrafast" preset will likely result in noticeable quality degradation compared to slower presets. If higher quality is important, consider using faster presets like "superfast" or "veryfast" which offer a better balance between speed and quality.
For even faster encoding, you can explore hardware acceleration options like NVENC (for NVIDIA GPUs) or QuickSync (for Intel GPUs) if your system supports them.
Intel hardware encoding:
# ffmpeg -i s01e01.mkv -c:v h264_qsv -c:a copy -vf "subtitles=s01e01.mkv:stream_index=1" output2.mkv
This gives encoding fps of around 180
Another option: -preset veryfast
Sharpening
Using the -vf option.
# Strong luma sharpen effect parameters unsharp=7:7:2.5 PvdM: dit betekent [unsharp @ 0x64f7c0] effect:sharpen type:luma msize_x:7 msize_y:7 amount:2.50 # Strong blur of both luma and chroma parameters unsharp=7:7:-2:7:7:-2 # Use the default values with ffmpeg ./ffmpeg -i in.avi -vf "unsharp" out.mp4 PvdM: dit betekent [unsharp @ 0x64f7a0] effect:sharpen type:luma msize_x:5 msize_y:5 amount:1.00
Example:
ffmpeg -i part1.dv -vf "unsharp" -target dvd test2.mpg
PvdM: getest en werkt goed:
#ffmpeg -i out.dv -vf unsharp=9:9:1.5:9:9:1.5 out2.dv
Image Stabilizing
$ ffmpeg -i $invoer -vf vidstabdetect -f null - $ ffmpeg -i $invoer -vf vidstabtransform=crop=black:smoothing=20,unsharp=5:5:0.8:3:3:0.4 $invoer.stabilized.mp4
This is a 2 trap proccess
Timestamps
To set the timestamp of the file to the video's internal creation date/time, you can use:
exiftool '-CreateDate>FileModifyDate' FILE
To force a date/time when converting:
ffmpeg -i 00041.MTS -vcodec mpeg4 -acodec copy -timestamp 2000012312:21:34 bla.mp4
Split video files
ffmpeg -i input.mpg -ss 00:00:10 -t 00:00:30 out1.mpg
-ss is the start point in hh:mm:ss from the beginning of your video file
-t is the length of time in hh:mm:ss of your new segment.
-to is the end time hh:mm:ss of the new segment.
So, in the above example, you're starting 10 seconds in from the beginning of the original file and ending 30 seconds later.
If you want to create multiple parts in one pass then the following should work:
ffmpeg -i input.mpg -ss 00:00:10 -t 00:00:30 out1.mpg -ss 00:00:35 -t 00:00:30 out2.mpg
In this example, the first segment is the same as the first example, but you're also creating a second file starting at 35 seconds in and being 30 seconds long.
Remember to use the correct encoding:
ffmpeg -i input.mpg -ss 00:00:10 -vcodec copy -acodec copy output.mpg
Cut an avi file from second 1 to 12.9.
mencoder -ss 00:01 -endpos 00:12.900 -ovc copy -oac copy -o out.avi in.avi
Merge video files
To merge 2 or more files, use the 'cat' command and pipe it through ffmpeg, like this:
cat 1.mpg 2.mpg | ffmpeg (-f mpeg) -i – -vcodec copy -acodec copy outfile.mpg
Unfortunately, this does not work. Again, mencoder to the rescue:
mencoder -oac copy -ovc copy -o output.mp4 1.mp4 2.mp4
Flip video files
hflip and vflip
ffmpeg -i input.mp4 -vf hflip,vflip,format=yuv420p -codec:v libx264 -preset medium -crf 23 -codec:a copy output.mkv
The above did not work, but this did:
ffmpeg -i VID_20130915_110755.mp4 -vf transpose=2,transpose=2 output.mp4
rotate video files 90 degrees counterclockwise
ffmpeg -i 20160416_152451.mp4 -vf transpose=2 -c:a copy output.mp4
create timelapse movie
To create a timelapse movie from images in a directory, use:
mencoder "mf://*.jpg" -mf fps=5 -o test.avi -ovc lavc -lavcopts vcodec=msmpeg4v2:vbitrate=1000
I know, this is mencoder, but it works.
FFmpeg uses the following format:
ffmpeg -f image2 -r 10 -b:v 1M -i %03d.jpg test2.mp4
but this doesn't work. Also it requires the imagefilenames to be of name 001.jpg - 999.jpg, which is not always the case.
Rename files sequentially
cnt=1;for i in `ls *.jpg`; do mv ${i} ${cnt}.jpg;cnt=$((cnt+1)); done
To list available formats (supported pixel formats, video formats, and frame sizes) for a particular input device:
$ ffmpeg -f v4l2 -list_formats all -i /dev/video0
Alternatively you could use
v4l2-ctl --list-formats-ext
to list available formats.
To take a picture with a webcam
ffmpeg -f video4linux2 -i /dev/video0 -vframes 1 test.jpeg
To record video with a webcam
ffmpeg -f video4linux2 -s 640x480 -r 20 -i /dev/video0 -f m4v out.m4v
-r = framerate
to stream live to youtube from IPCAM
ffmpeg -rtsp_transport tcp -i "rtsp://192.168.1.34:554/iphone/11?username:password" -f lavfi -i anullsrc=r=16000:cl=mono -c:a aac -ar 44100 -pix_fmt yuv420p -preset medium -s 1280x720 -bufsize 6000k -vb 6000k -maxrate 6000k -deinterlace -vcodec libx264 -crf 18 -r 50 -f flv -force_key_frames source -x264-params keyint=20:scenecut=0 "rtmp://a.rtmp.youtube.com/live2/<YT id>
record the screen, capture the desktop
Use the x11grab device:
ffmpeg -video_size 1024x768 -framerate 25 -f x11grab -i :0.0+100,200 output.mp4
This will grab the image from desktop, starting with the upper-left corner at (x=100, y=200) with the width and height of 1024x768.
If you need audio too you can use ALSA (see Capture/ALSA for more info):
ffmpeg -video_size 1024x768 -framerate 25 -f x11grab -i :0.0+100,200 -f alsa -ac 2 -i hw:0 output.mkv
Or the pulse input device:
ffmpeg -video_size 1024x768 -framerate 25 -f x11grab -i :0.0+100,200 -f pulse -ac 2 -i default output.mkv
Record fullscreen TV image (ziggo stream):
ffmpeg -video_size 1600x900 -framerate 30 -f x11grab -i :0.0 -c:v libx264 -qp 0 -preset ultrafast -f pulse -ac 2 -i default capture.mkv
deze werkt:
ffmpeg -video_size 1920x1080 -framerate 15 -f x11grab -i :0.0 -f pulse -ac 2 -i default -c:v libx264 -qp 0 -preset ultrafast capture.mkv
Merging video and audio, with audio re-encoding
See this example, taken from this blog entry but updated for newer syntax. It should be something to the effect of:
ffmpeg -i video.mp4 -i audio.wav -c:v copy -c:a aac -strict experimental output.mp4
Here, we assume that the video file does not contain any audio stream yet, and that you want to have the same output format (here, MP4) as the input format.
The above command transcodes the audio, since MP4s cannot carry PCM audio streams. You can use any other desired audio codec if you want. See the AAC Encoding Guide for more info.
If your audio or video stream is longer, you can add the -shortest option so that ffmpeg will stop encoding once one file ends.
Copying the audio without re-encoding
If your output container can handle (almost) any codec – like MKV – then you can simply copy both audio and video streams:
ffmpeg -i video.mp4 -i audio.wav -c copy output.mkv
Replacing audio stream
If your input video already contains audio, and you want to replace it, you need to tell ffmpeg which audio stream to take:
ffmpeg -i video.mp4 -i audio.wav -c:v copy -c:a aac -strict experimental -map 0:v:0 -map 1:a:0 output.mp4
The map option makes ffmpeg only use the first video stream from the first input and the first audio stream from the second input for the output file.
extract images from a video
ffmpeg -i giveafuck.mp4 image-%3d.jpeg
-r This is used to set the frame rate of video. i.e. no. of frames to be extracted into images per second. The default value is 25, using which, would have yielded a large number of images.
Create a thumbnail image every X seconds of the video
Output a single frame from the video into an image file:
ffmpeg -i input.flv -ss 00:00:14.435 -vframes 1 out.png
This example will seek to the position of 0h:0m:14sec:435msec and output one frame (-vframes 1) from that position into a PNG file.
Output one image every second, named out1.png, out2.png, out3.png, etc.:
ffmpeg -i input.flv -vf fps=1 out%d.png
Output one image every minute, named img001.jpg, img002.jpg, img003.jpg, etc. The %03d dictates that the ordinal number of each output image will be formatted using 3 digits:
ffmpeg -i myvideo.avi -vf fps=1/60 img%03d.jpg
Output one image every ten minutes:
ffmpeg -i test.flv -vf fps=1/600 thumb%04d.bmp
Merge pictures into an Animated GIF
convert -delay <ticks>x<ticks-per-second> -loop 0 out*gif <output-gif-file>
In the command, "-delay" is an option that controls the animation speed. This option indicates that [ticks/ticks-per-second] seconds must elapse before the display of the next frame. The "-loop 0" option indicates infinite loops of animation. If you want, you can specify "-loop N", in which case the animation will repeat itself N times.
For example, to create an animated GIF image with 20 frames-per-second and infinite loop, use the following command.
$ convert -delay 1x20 -loop 0 out*.gif animation.gif
The last (optional) step is to reduce the size of the created GIF file, by using ImageMagick's GIF optimizer.
Use the following command to reduce the GIF size.
$ convert -layers Optimize animation.gif animation_small.gif
DVD
Rip entire DVD
# cat *.VOB | ffmpeg -i - -acodec aac -aq 100 -ac 2 -vcodec libx264 -crf 24 -threads 0 /data/pil.mp4
Re-encode for DVD use
# mythreplex --demux --fix_sync -o /data/stream -v 224 -c 128 "/data/newfile2.mpg # tcrequant /data/stream.mv2 /data/video.small.m2v 1.17052143685
Pull Chapters from VOB
You can pull chapters from VOB files using mplayer. Here's a command line to pull chapter 3 from the DVD drive and dump it to a VOB.
mplayer dvd:// -chapter 3-3 -dumpstream -dumpfile 3.vob
- physical DVD
mplayer dvd://2 -chapter 3-3 -dumpstream -dumpfile ~/3.VOB
- DVD .iso image
mplayer dvd://2 -dvd-device "$dvd_iso" -chapter 3-3 -dumpstream -dumpfile ~/3.VOB
Rip VOB to mpeg4
and deinterlace as well.
ffmpeg -i VTS_01_1.VOB -vcodec mpeg4 -b:v 10M -acodec copy -deinterlace lan1deinterlaced.mp4
Rip VOB to DV
The following command will rip a VOB file strait from an unencrypted DVD and convert it to a strait DV file.
ffmpeg -i /cdrom/VIDEO_TS/VTS_01_1.VOB -target dv /home/joel/Videos/game_vi.dv
Rip VOB to DVD
The following command will rip a VOB file to an MPEG2 video with AC3 audio for a DVD. It also uses the '-sameq' option which uses the same quality factor in the encoder as in the decoder, allowing almost lossless encoding.
ffmpeg -i myfile.vob -target dvd -sameq myfile.mpg
Rip VOB to VCD
The following command will rip a VOB file to a MPEG1 video with MP1 audio.
ffmpeg -i myfile.vob -target vcd myfile.mpg
Rip VOB to Flash (FLV)
The following command will rip a VOB file to 352×240 (the same size as VCD) and will save it as a flash file.
ffmpeg -i myfile.vob -s 352x240 myfile.flv
Rip VOB to FLAC audio
The following command will extract an AUDIO-DVD files to flac. List the VOB files in order:
cat VTS_01_1.VOB VTS_01_2.VOB | ffmpeg -i - -acodec flac -vn output.flac
unfortunately, there will be no CUE file.
Audio
Adjust volume of audio file
ffmpeg -i input.wav -af "volume=5dB" output.mp3
gives a 5 dB gain
combine multiple sources to one destination
# ffmpeg -f concat -i /tmp/list.txt output3.flac
where list.txt contains:
file '/tmp/file1' file '/tmp/file2'
or try:
ffmpeg -i "concat:input1.mpg|input2.mpg|input3.mpg" -c copy output.mpg
better still:
ffmpeg -f concat -i <( for f in *.wav; do echo "file '$(pwd)/$f'"; done ) output.wav
Convert .dsf files (SACD) to standard .wav files (PCM - CD quality)
ffmpeg -i 04.dsf -acodec pcm_s16le -ar 44100 -ac 2 output.wav
This however, does not give enough audio quality.
The Golden Line:
ffmpeg -i input.dsf -acodec pcm_s24le -ar 44100 -ac 2 44100_24.wav
I have tried it with 32 bits and with 88200 and higher, could not hear it.
copy/convert from multistream sources
Given the following input file:
# fmpeg -i input.mkv
ffmpeg version ... Copyright (c) 2000-2012 the FFmpeg developers
...
Input #0, matroska,webm, from 'input.mkv':

If we want to extract only audio streams, from input file, then we can do it like this:
ffmpeg -i input.mkv -map 0:1 -map 0:2 -c copy output.mkv
or use the appropriate codecs
Create multichannel WAVs or FLACs
This command will 'rip' the first 5 minutes (which is the first song actually) of a quadraphonic (4.0) .WAV file that is 45 minutes long:
ffmpeg -i The\ Doobie\ Bothers-\ Toulouse\ Street.wav -acodec pcm_s16le -b:a 1400k -ss 0:0:0 -t 0:5:0 \ -ac 4 -map_channel 0.0.0 -map_channel 0.0.1 -map_channel 0.0.4 -map_channel 0.0.5 output.wav -y
The resulting file 'output.wav' will be a multichannel wav with the following channel order:
1. front left
2. front right
3. rear left
4. rear right
When loaded into audacity, and then when exported into either .WAV or .FLAC move the channel slider to 6 channels and the following channel mix must be done:
output 1 -> channel: 1
output 2 -> channel: 2
output 3 -> channel: 5
output 4 -> channel: 6
Extract channels from multitrack sources
To extract the center channel (channel 3, counting the channels starts at 0) which is usually the solo voice and/or other interesting discrete stuff:
# ffmpeg -i yes.flac -ac 1 -map_channel 0.0.2 center.flac
Channel identification
I found this:
The track order of all 5.1 surround files follows the standard as defined by SMPT/EBU and implemented by SourceForge in FLAC (v. 1.2.1b): L – R – C – Lfe – Ls - Rs flac.sourceforge.net
Also:
In accordance with ANSI/CEA-863-A<ref>Consumer Electronics Association standards: Setup and Connection</ref>
| Zero-based order within multi-channel mp3/wav/flac datastream |
Order within DTS/AAC |
Channel name | Color-coding on commercial receiver and cabling |
|---|---|---|---|
| 0 | 1 | Front left | White |
| 1 | 2 | Front right | Red |
| 2 | 0 | Center | Green |
| 3 | 5 | Low frequency | Purple |
| 4 | 3 | Surround left | Blue |
| 5 | 4 | Surround right | Grey |
| 6 | 6 | Surround back left | Brown |
| 7 | 7 | Surround back right | Khaki |
| Front left | Center | Front right |
| Surround left | Surround right | |
| Surround back left | Surround back right | |

Standard speaker channels
This table shows the various speaker configurations that are commonly used for end-user equipment. The order and identifiers are those specified for the channel mask in the standard uncompressed WAV file format (which contains a raw multichannel PCM stream) and are used according to the same specification for most PC connectible digital sound hardware and PC operating systems capable of handling multiple channels. While it is certainly possible to build any speaker configuration, there isn't a lot of commercially available movie or music content for alternative speaker configurations. Such cases, however, can be worked around by remixing the source content channels to the speaker channels using a matrix table specifying how much of each content channel is played through each speaker channel.

Downmix of multichannel 5.1 audio to real quad 4 channel four speaker
A lot of surround music today is supplied in a 5.1 channel format. That means front left, front right, center, subwoofer, rear left, and rear right channel. But if you have a quadraphonic setup like me, you only have 4 speakers, which are real speakers, so no subwoofer is present nor needed. And the center speaker is also absent. So you have left front, right front, left rear and right rear.
But then you have a problem with the voices in the surround mix, which are usually mixed on the center channel. Sometimes the vocals are ONLY mixed into the center channel. Without a center channel setup, you will hear no vocals. Sometimes vocals are duplicated in the front left and right channel in the audio mix, but then the vocals will sound thin, if present at all. So what is needed is a downmix of the center channel to the two front channels. Or in other words:
quad destination: 5.1 source: left front <- left front + center channel right front <- right front + center channel left rear <- left rear right rear <- right rear
This can be achieved by the following ffmpeg command: (where $i is the surround file)
ffmpeg -i "$i" -af "pan=quad|c0<c0+c2|c1<c1+c2|c2=c4|c3=c5" "$i.flac"
Or, for a complete directory:
IFS=$(echo -en "\n\b"); for i in *.wav; do ffmpeg -i "$i" -af "pan=quad|c0<c0+c2|c1<c1+c2|c2=c4|c3=c5" "$i.flac"; done
Compand
ffmpeg -i input.wav -filter:a "dynaudnorm" output.wav
You will most likely need to tweak the filter options for your particular use case. Use the examples given for the compand filter as a starting point:
Make music with both quiet and loud passages suitable for listening to in a noisy environment:
compand=.3|.3:1|1:-90/-60|-60/-40|-40/-30|-20/-20:6:0:-90:0.2
Another example for audio with whisper and explosion parts:
compand=0|0:1|1:-90/-900|-70/-70|-30/-9|0/-3:6:0:0:0
Here, the second example's options are, specifically:
attacks=0|0 decays=1|1 points=-90/-900|-70/-70|-30/-9|0/-3 soft-knee=6 gain=0 volume=0 delay=0
You may adjust the gain to keep the same dynamic processing but adjust it to your baseline input level.
More examples: Make music with both quiet and loud passages suitable for listening to in a noisy environment: compand=.3|.3:1|1:-90/-60|-60/-40|-40/-30|-20/-20:6:0:-90:0.2 Another example for audio with whisper and explosion parts:
compand=0|0:1|1:-90/-900|-70/-70|-30/-9|0/-3:6:0:0:0 A noise gate for when the noise is at a lower level than the signal:
compand=.1|.1:.2|.2:-900/-900|-50.1/-900|-50/-50:.01:0:-90:.1
Here is another noise gate, this time for when the noise is at a higher level than the signal (making it, in some ways, similar to squelch):
compand=.1|.1:.1|.1:-45.1/-45.1|-45/-900|0/-900:.01:45:-90:.1

For example, the h263 decoder corresponds to the h263 and h263p encoders, for file formats it is even worse.
