-vn removes tha video content, the copy option tells ffmpeg to use the same codec for generating the output

Takes an mpeg video and coverts it to a youtube compatible flv file. The -r 25 sets the frame rate for PAL, for NTSC use 29.97

Creates a new video file with video stream copied from input file and a different audio stream

This command will transcode a MythTV recording. The target device is a Google Nexus One mobile phone. My recordings are from a HDHomerun with Over The Air content. Plays back nicely on the N1.

i have a large video file, 500+ MB, so i cant upload it to flickr, so to reduce the size i split it into 2 files. the command shows the splitting for the first file, from 0-4 minutes. ss is start time and t is duration (how long you want the output file to be). credit goes to philc: http://ubuntuforums.org/showthread.php?t=480343 NOTE: when i made the second half of the video, i got a *lot* of lines like this: frame= 0 fps= 0 q=0.0 size= 0kB time=10000000000.00 bitrate= 0.0kbit just be patient, it is working =) Show Sample Output

Faster thumbnail creation than '-itsoffset' ffmpeg -itsoffset -4 -i test.avi -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 test.jpg Show Sample Output

Errors in output don't matter. Stop recording: ctrl-c. Result playable with Flash too. IMPORTANT: Find a Pulse Audio device to capture from: pactl list | grep -A2 'Source #' | grep 'Name: ' | cut -d" " -f2 Show Sample Output

If it's Hebrew [most probably all RTL languages. Comments?], add -flip-hebrew and -noflip-hebrew-commas to the mplayer switches: transcode -i myvideo.avi -x mplayer="-utf8 -flip-hebrew -noflip-hebrew-commas -sub myvideo.srt" -o myvideo_subtitled.avi -y xvid

Assumes you've downloaded Toni Corvera's vcs script (http://p.outlyer.net/vcs), have it in your PATH, and have installed the script's dependencies. Generates a video contact sheet of 24 thumbnails and 3 thumbnails per column. The bold font and white-on-black color scheme keeps the text readable at the chosen 70% JPEG compression quality, which keeps the file size at a manageable level. You can go even lower with the quality and get a good looking result.

Change video orientation in metadata only

Displays only the VGA adapter/chipset being used for the graphics. In this case, it gave me the "M22" and "Mobility Radeon x300" that I needed to research a graphics issue I was having. Show Sample Output

video.avi is the resulting file. Press Ctrl+c to stop the recording. You can change the OVC option to another to record into a different format.

Encode video.avi into newvideo.avi using the libav codec to produce an MPEG4 file with a bitrate of 800

Gives MPEG-4/DivX output video file ready for uploading to YouTube from FLV file downloaded from the site and your own subtitle file UTF-8 encoded. No resizing needed. (?)

Remove sound from input video file, output video stream is copied from input video stream, with no audio.

Convert those .mov files that your digital camera makes to .avi Adjust the bitrate (-b) to get the appropriate file size. A larger bitrate produces a larger (higher quality) .avi file and smaller bitrate produces a smaller (lower quality) .avi file. Requires ffmpeg (see man page for details) (tested with canon camera MOV files) Other examples: ffmpeg -i input.mov -sameq -vcodec msmpeg4v2 -acodec pcm_u8 output.avi ffmpeg -i input.mov -b 1024k -vcodec msmpeg4v2 -acodec pcm_u8 output.avi

Gets all videos in your boxee queue with a URL associated with them and attempts to download each using get_flash_videos

Videos are found using their MIME type. Thus no need to for an extension for the video file. This is a efficent version of "jnash" cmd (4086). Thanks for jnash. This cmd will only show video files while his cmd show files having "video" anywhere in path. Show Sample Output

Replace vid.mp4 with the path to your original video file, and out.mp4 to the path where you want to save the new file. To view the output first before saving, remove "-consumer avformat:out.mp4" from the end. Documentation for mlt framework and melt command can be found here: http://www.mltframework.org/bin/view/MLT/Documentation

We take the first 50 frames of a.mp4 for track a, and 24 blank frames followed by b.mp4 for track b. We then create a transition from track a to track b starting from frame 25 and ending at frame 49. The output is stored in out.mp4 To view the results without saving remove "-consumer avformat:out.mp4" from the end. Documentation of the mlt framework and the melt command can be found here: http://www.mltframework.org/bin/view/MLT/Documentation

Download video files from a bunch of sites (here is a list https://rg3.github.io/youtube-dl/supportedsites.html). The options say: base filename on title, ignores errors and continue partial downloads. Also, stores some metadata into a .json file plz. Paste youtube users and playlists for extra fun. Protip: git-annex loves these files Show Sample Output

First, we convert the VMware avi (VMnc format) to the Microsoft avi format. Next, we convert the Microsoft avi format to FLV format. You can play around with the -r switch (rate per second) and the -b switch (bitrate). But, if those get larger, so does your FLV file.

Create subtitle file heading.ssa with just one entry for the entire video duration. Command line sets that entry's text on top of the video as text watermark. If text is an URL works nice for sending people back to your site from a YouTube clip. Output file is lossless encoded and suitable for further processing. Subtitle file can be a URL so it's saved remotely.

Rips DVD to lossless encoded video file. Reencodes audio to CBR MP3 for correct audio to video syncing. Be sure to have enough free disk space.
