But what has improved? Are the 2 filter options now chained instead overridden? -Ulf ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

The correct syntax for chaining filters is the comma: https://ffmpeg.org/ffmpeg-filters.html#Filtering-Introduction "Filters in the same linear chain are separated by commas, and distinct linear chains of filters are separated by semicolons." So your second command is the one you intended.

Re: [FFmpeg-user] How to correctly chain filters
In the first one, the second -vf option overrides the one before it, so the bwdif filter isn't applied. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
[FFmpeg-user] How to correctly chain filters
Hi, I have tried 2 forms: $ ffmpeg -i in.vob -movflags +faststart -vf bwdif -vf hqdn3d -q 3 -c:a copy out_bwdif_hqdn3d.vob $ ffmpeg -i in.vob -movflags +faststart -vf bwdif,hqdn3d -q 3 -c:a copy out_bwdif,hqdn3d.vob The 1st one results in a file of size 229 MB, the 2nd of size 328 MB. Can anyone tell me, what is the difference of both syntax?
