• Get information about a video: 

    $ tcprobe -i ./video.avi

  • Merge multiple video into one: 

    $ avimerge -i part1.avi part2.avi -o big-file.avi

  • Extract the raw subtitle stream. The -a 0x21 option correspond to the subtitle stream’s hexadecimal number (= 0x20 + id of the stream): 

    $ tccat -i /space/st-tng/dic1/ -T 1 -L | tcextract -x ps1 -t vob -a 0x22 > subs-en

  • List export video codecs: 

    $ transcode -i . -y ffmpeg -F list

  • Extract all frames of a video and save them as .jpg : 

    $ transcode -i video.avi -y im

  • Batch stabilization script: 

    SEARCH_FOLDER="/home/kevin/project/raw_sources"
DEST_FOLDER="/home/kevin/project/stabilized"

for FILE_PATH in $(find "$SEARCH_FOLDER" -name "*.mp4"); do
	FILE_NAME=$(basename "$FILE_PATH")
