How would you render H.265? As it stands, compatibility is a big problem. Players that use the LAV decoder, including Windows Media Player and MPC-HC, won't play Vegas H.265 renders smoothly, and the popular VLC Player won't play Handbrake H.265 renders smoothly.

I don't care that VLC is having problems with H.265 files rendered by Handbrake, since all my other PC players do play it smoothly and also my UHDTV and stand alone player work fine with these files.

If you’re selling a video for download, you might have to care.

+1 red prince.

what you do for yourself is one thing, but if you want to guarantee anyone else can view it then you're doing yourself a disservice.

You are right. I missed this point. On the other side MikeLV wants to provide the videos as downloads and if you render UHD or long videos size may also matter. Probably a player recommendation could help.

I would be encoding using Handbrake. As far as the material, it will be a mix of older DVDs (SD resolution) and the new stuff would probably be no more than 720P. Not shooting hollywood epics here, just some rote educational material. So yes, maximum compatibility is key. In my instructions that come with the downloads, I'll probably recommend VLC since it's freely available on all major platforms. With HB, I'm getting pretty good quality SD H.264 at around 3 to 4 MB per minute using the very slow setting. Does that sound about right for basically talking head material?

so you should test these HB output files with VLC, since Nick found problems playing UHDp30 HEVC files encoded with HandBrake 1.0.1 with VLC.

I'm probably not going to need H.265 as we changed and will be offering streaming videos, e.g. through Vimeo, so whatever we upload to them will be encoded anyways.

x264 is fine at HD resolutions including 1080p 60.

x265 is stable and has good compression at 4k/uhd, but the burden of horrendous encoding times needs to be considered.

On the DJI Phantom 4 Advanced, it gives you a choice to encode in 264 or 265. Would the decision then be based on the destination media? For instance, go with 64 if primary HD and 65 if primarily UHD? It is 64 by default but 65 seems better not only in terms of file size but pic quality.

Thanks!

I guess you could say it that way.

h265 is not higher quality, because that is limited by the source, and it's an easy job to hit optimal quality metrics with either encoder.

It's better to say h265 will produce the SAME quality at a smaller size and bandwidth.

But h264 has good compression and superior encoding speed. So all else being equal, h264 has all the advantage in 2018, unless you are streaming UHD from your own servers.

That role will turn you into a bit-miser in a heartbeat...
