Commands tagged mencoder

Requires mencoder.

Takes two input video files and an external audio track and encodes them together to an MPEG-4 DivX output video file with the correct size ready for uploading.

MEncoder can create MPEG (MPEG-PS) format output files. Usually, when you are using MPEG-1 or MPEG-2 video, it is because you are encoding for a constrained format such as SVCD, VCD, or DVD.

To change MEncoder's output file format, use the -of mpeg option.

Creating an MPEG-1 file suitable to be played on systems with minimal multimedia support, such as default Windows installs:

-o output.mpg -oac lavc -lavcopts acodec=mp2:abitrate=224 -ovc lavc \

-lavcopts vcodec=mpeg1video:vbitrate=1152:keyint=15:mbd=2:aspect=4/3

Examples:

The following will take frames starting at 15.2 seconds for a total of 45.9 seconds:

Keep in mind -endpos is the total time, i.e. the output video in this is 3 minutes 3 seconds in length:

Reencodes to MPEG-4 DivX output video file from step 1. Audio stream is simply copied. Resizes to 320x240 and deinterlaces as needed. A heading subtitle file is applied as watermark. This heading subtitle file can be a URL.

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.

Rip DVD to YouTube ready AVI file, using MPEG-4 video codec and MP3 audio codec. Resizes to 320x240 and deinterlaces as needed.

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.

Record audio to MP3 stream and video to MPEG-4 stream from webcam to AVI file using mencoder. Gives floating point exception in some mencoder versions.

Extracts an MP3 encoded audio stream from an input video file.

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

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

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. (?)

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.

This set of commands will rip a dvd title using a 2 pass mencoder xvid encode. It will provide a great quality rip. It will rip as close to 700MB as possible. (note the bitrate of -700000)

Enjoy!

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

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.

When playback of AVI files (containing a video format like XviD or DivX) is stuttering, it in 90% of the files is caused by a poorly or wrongly interleaved file. The issue can be permanently resolved by RE-MUXING the AVI video-files that have this problem
