The 3 messages I link to show how you can use FFMPEG to resize and combine 2 videos to create a L|R side-by-side comparison clip, say of the effects of a filter. I also add title overlays to the 2 clips. The FFMPEG filter I was examining is vid.stab, an image stabilisation filter. There are links to a suitable jerky test clip, and two processed examples. A batchfile test-bench you can use for side-by-side filter comparisons is included. This could be used as a template for comparing the effect of other filters.
Due to the large number of parameters than can be changed, you edit the batchfile, rather than specifying them on a CLI. So I keep the batchfile open in a text editor (Notepad++) in a separate window as I run the batchfile in a windowed console session. https://forums.whirlpool.net.au/thread/3q68l4j9#r5 https://forums.whirlpool.net.au/thread/3q68l4j9#r6 https://forums.whirlpool.net.au/thread/3q68l4j9#r7 Dan. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
