Experiencing a progressive loss of audio sync in a video? Variable framerates may be the cause.
This tool is an AviSynth script with GUI which uses Avidemux as a backend. It simplifies and automates the process of converting variable framerate video to constant framerate video.
Features
Transcoding to constant framerate.
Batch processing.
Limitations
Audio tracks are not processed. Mux them after conversion.
Avidemux filters are not supported or processed.
Revision History:
Version 1.8.11.9
Release Date: Nov 20, 2008
Renamed X264 codec preset options to 'Best', 'Quality', and 'Archival'.
Added 'Improve Output Quality' to x264 Dialog and its' config xml and methods. This enables higher quality encoding but is somewhat slower.
Recoded filters dialog resize presets, so that width is calculated from the selection instead of using hardcoded values.
Added AutoDetect to Video Duration section of JobDialog. This optional feature runs Avidemux to index the video file and return the duration. NOTE this may take several minutes depending on the size of the video. Fortunately, this only needs to be performed once, so the user has the option of doing it here or during batch processing.
Changed Deinterlace video filter serialization values and UI selection control. Saved jobs should be executed before upgrading to this version.
