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.
Added a 'Reset Filter' utility because of the ongoing random issues with all codecs where blocky and blurry areas
appear in the rendered output. Deblocking commands were useless. A possible cause is the framecount attribute
in DirectShowSource which seems to trigger the problem. The new utility runs a sample render job to reset the filter
used by DirectShowSource. It is usually successful but must be used again if blocky output occurs.
