Everything I've read says that h.265 is mainly useful at higher resolution and it definitely uses more CPU for the compression so I'm sticking with h.264. _______________________________________________ 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".
