Maybe because only horizontal scaling was done. These are home DV movies shot with an unnEUterized Sony TRV320E and old VHS digitized with it. Several years ago I converted them all to deinterlaced H.264 with simple deinterlace. That quality is OK but I plan to re-encode those archived .dv files again with bob deinterlace as H.265 with smoother motion and slightly better quality with about the same or little larger file size. Some noisy DV scenes need CRF below 22. I tried to search noise reduction filters but maybe I just use CRF 18-20 for all material. The old VHS footage compresses well with bitrate automatically adjusted quite low with CRF 18 and even CRF 24 is OK with it. - Matti _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
