What's up with H.265?

So I tried the long awaited H.265 codec - and yes, VP 14 can render to it (in the MOV container), bat as for reading - it only seems to be able to recognize it's own rendered clips! Even a HEVC clip rendered out from Mercalli 4.0 SAL is not recognized, and only the audio track is loaded... What am I missing?

Can Vegas Pro 14 read 10-bit HEVC files?

If you can find a sample to try, we'll test it.

Yes it now can, although with artefacts (green frames).

PS. As an afterthought, perhaps the green frame (usually at the very beginning) is caused by the HDR flagging that VP 14 doesn't understand? All my HEVC clips has been encoded with this flag... But you can download some 10-bit h.265 clips (2 last of them, at the very bottom, are in HDR) - and compare yourself:

I just tried reading some 10-bit HEVC files in Vegas Pro 14. It could read the 4:2:0 file (MP4 and MOV), and with 10-bit precision. It could not read 4:2:2 or 4:4:4 files. I guess I'm stuck using XAVC if I want 4:2:2.

It depends on your very purpose. For 4:2:2 video there are several choices in Vegas Pro which work for input and output: V210 (Sony YUV 10 bit), CineForm (10 bit), GV HQX, XDCAM HD, XDCAM SR (10 bit), XAVC (10 bit), ProRes (10 bit), P2.

Edit:
I just tested 10 bit HEVC from the link given above (the HDR versions). Though playback performance is pretty bad on my notebook these files decode correctly without any issues (except performance). I renamed from *.mp4 to *.mov.
I then used Vegas' proxy workflow to overcome low playback performance and this worked fine.

So I think the answer is: Yes, Vegas Pro 14 can read 10 bit HEVC – at least in some cases. Issues may be bound to the given GPU which is used for HEVC decoding.

I love how the exceedingly cheaper VideoPad Video Editor can handle ANY format thrown at it, but my GoPro, Mavic Air, and Osmo videos and pictures give this "high end" software so much issue. Rendering to and from any format takes a quarter of the time and I have never had it hang. I regret this purchase so far. I have a 10 minute video at 1% in Vegas 14 pro, and its 7 minutes in and counting upwards of three hours...and still going up. Ridiculous.
