Yes, *if* the target bitrate(s) are expected to be lower to fit within specific constraints, such as live streaming and archival, and with an acceptable trade off in quality for saved bandwidth & storage. Even then, the target encoder(s) must be tuned specifically for the workload(s) in question. In other words, re-encoding with the x265 codec for the final video : can it improve the final video quality, compared to the source video, when the source video is encoded with x264 ? No, video quality will actually degrade. Both are lossy codecs by design. _______________________________________________ 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".
