I am recording my computer with an Elgato 4K60S+, the output format is H.265, I can import in PS-25-Ult, can edit, but cannot export using the "same as timeline" or HEVC/H.265.

 

When exporting the progress bar stock at 1%. 

From Pinnacle's website.

Export Formats

• Disc: DVD, AVCHD, Blu-ray ($)
• Video: DV, HDV, AVI, WMV, MPEG-1/-2/-4, Flash, 3GP, HEVC** (H.265, H.264),

 ** HEVC (H.265) support requires supporting PC hardware or graphics card and Microsoft HEVC video extension installed.

You have to go to the M$ store HERE and buy it. 

It was free for a long time, along with the HEIC, but you know M$.....

OP says that he can launch HEVC export and then it stalls. It can't be a matter of HEVC extension missing in Windows.

The OP would have to tell us if he has the Extension installed.

I've had the Extension for a couple of years installed, so can not comment on if I would be able to import and then export a HEVC file.

IMO the OP should also tell us what CPU and graphics card he has (if a discrete GPU); some older and low-end GPUs can decode but not encode HEVC, or might not handle 4K

Don't forget the 'magic' "use 3rd-party codecs" checkbox in the Control Panel...

Useless in this case.

I bought all extension, HEVC, but if you know a way to check the correct installation of the CODEC ?

 

 

 CPU AMD Ryzen 9 5950X

GPU AMD 6900XT 

 

 

 I do not have any problem with importing H265 or H264, then export H264.  Only when export H265 it frozen.

I would guess actually try to export HEVC?

If you go back to the M$ store from your account to look again at the HEVC, it should say something along the lines of "This product is installed."

If the Microsoft HEVC extension was not installed, HEVC would not be available in Studio.
