This *does not change the video encoding*, so it's fast (almost purely I/O-bound) and results in a file of nearly the same size. However, OSX (and possibly other programs) will more easily play/seek the file when wrapped as MOV. For example, you can QuickLook the resulting file. This basically does the same as the commercial ClipWrap program, except using the free program ffmpeg. Show Sample Output

ffmpeg -i "input.mts" -vcodec copy -acodec pcm_s16le "output.mov"

Remove excess noise from a set of mp4 videos.

Full command: for f in input/*; do BN=$(basename "$f"); ffmpeg -i "$f" -vn "temp/$BN.flac"; sox "temp/$BN.flac" "temp/$BN-cleaned.flac" noisered profile 0.3; ffmpeg -i "$f" -vcodec copy -an "temp/$BN-na.mp4"; ffmpeg -i "temp/$BN-na.mp4" -i "temp/$BN-cleaned.flac" "output/$BN"; done This was over the 255 character limit and I didn't feel like deliberately obfuscating it. 1. Create 'input', 'output' and 'temp' directories. 2. Place the files that you want to remove the hiss/static/general noise from in the input directory. 3. Generate a noise reduction profile with sox using 'sox an_input_file.mp4 -n trim x y noiseprof profile', where x and y indicates a range in seconds that only the sound you want to eliminate is present in. 4. Run the command.

Convert SWF to video

This will dump a raw BGRA pixel stream and WAV which must then be converted to video: ffmpeg -f rawvideo -c:v rawvideo -s 1280x720 -r 12 -pix_fmt bgra -i "${i%.*}".bgra -c:v libx264 -preset veryslow -qp 0 -movflags +faststart -i "${i%.*}".wav -c:a libfdk_aac -b:a 384k "${i%.*}".mp4 ; rm "${i%.*}".bgra "${i%.*}".wav Our example generates an x264/720p/12fps/AAC best-quality MP4. To get dump-gnash, first install the build-dependencies for gnash (this step is OS-specific). Then: git clone http://git.savannah.gnu.org/r/gnash.git ; cd gnash ; ./autogen.sh ; ./configure --enable-renderer=agg --enable-gui=dump --disable-menus --enable-media=ffmpeg --disable-jemalloc ; make

replace audio track in a video file

The "map" may be different depending on the .wmv file. run `ffprobe` to see which is the video-track in the .wmv file usually this is "0.0". Stream #0.0: Video:... Stream #0.1: Audio: .. and "1.0" corresponds to the 2nd input file - your new audio. You may want to add "-acodec wmav2" and "-ar 128k" options for 128kbit/s Windows Media Audio 2 or whatever audio-codec/quality your want. `ffmpeg -codecs | grep "EA"` gives you a list of available codecs for Encoding Audio. Try using '-sameq' instead of '-vcodec copy' (re-encode the video with same quality rather than a bit-exact copy - this often solves muxing issues but will cause a small loss of either video quality or increased bandwidth). and also try a different output format eg. 'new_video.avi' or '..mov' instead of 'new_video.wmv'. you may need both, this should work: ffmpeg -i vid.wmv -i aud.wav -sameq -map 0.0 -map 1.0 output.avi

Get AWS temporary credentials ready to export based on a MFA virtual appliance

You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials

Normalize volume output in MPlayer

Works really well for playing DVDs, which have the volume turned way down for some reason. The `2' method is better IMHO because it will adjust to changing loud/soft parts. If you want to add it to your ~/.mplayer/config: # format: volnorm[=method:target] # method: # 1: use single sample (default) # 2: multiple samples # target: # default is 0.25 af-add=volnorm=2:0.75
