Well, if you're driving a compact, and someone writes "you need to switch to a Jeep, because it can pull your trailer out of the mud", do you buy a Jeep? ;-) I'm trying to say: Try to understand the benefits and the disadvantages, and check against your requirements. Do you need less space? Are you willing to sacrifice encoding speed? Is H.265 the right codec for your type of videos? As Mick Finn pointed out, H.265 is more designed for higher resolutions and bit depths (IIUC). Can your target players even decode H.265? (Does the Jeep even fit into your parking spaces? Do your feet reach the pedals?) There's no matter of "must", "need to" - just of considerations. I believe whatever you read, implied some other details, or forgot to tell about them. BTW, if someone does magic hacking, or even more optimized GPUs emerge, x265/H.265 *may* become "faster" than x264/H.264. It isn't right now. > (what is not true, I did see 'only' a 2/3) It depends on the material.

Even if I could encode my material to H.265, I probably wouldn't, except when targetting a very specific player (modern smart phones?). My PVR/STB, my TV, ..., cannot decode it. Possibly even my PC doesn't have enough compute/GPU power to decode it in full HD. > In none of the hits I saw anything about a performance hit. Especially > not a hit up to a factor three. They should. ;) Cheers, Moritz _______________________________________________ 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".
