Note that you need to have FFmpeg built with vaapi or nvenc support, which is
not the case of Debian package.
I don't know what's needed for Intel, but for NVidia you have to download a SDK
linked to closed-source driver, providing personal information: showstopper for
me (and many packagers) :\
Please let us know of any progress on your side.
Evert, did you try to share your custom profiles using "HotNewStuff" function
in Kdenlive? ;)

Hi there, Bernd.
Kdenlive supports hardware encoding through custom encoding profiles.
This is my profile for hardware hevc encoding with nvidia:
properties=x265-medium f=matroska vcodec=hevc_nvenc acodec=aac crf=%quality
It would have been awesome if mlt and ffmpeg used the same format in command
lines, but this is not the case. At least they are close.
Unfortunately I only have intel cards, so I cannot test the intel vaapi
acelleration for you.

After some years without I'm getting back to video editing... I already
searched quite a lot but it's really hard to find "realiable" information, so I
decided to ask here:
- It seems that hw accel is not available in kdenlive
- As far as I understand kdenlive uses mlt which uses ffmpeg. ffpmeg can use
hardware acceleration for de- and encoding. So is mlt to "blame" for missing hw
accel. in kdenlive?
- There has been a patch (bug 378832) "use of vaapi in transcoding and
rendering" which seems to tackle my question. But what did it really change -/
what is it for? I didn't find more info on that and it's in kdenlive 17.04,
while Debian is at 16.12. and before I compile myself I'd like to get more info.
- Furthermore I found a thread on this list back in April "kdenlive and mlt
nvenc enabled" covering the same topic but for nvidia instead of Intel
graphics; unfortunately nobody reported back if it really works. For me it
reads like the patch I mentioned above.
So regarding the current state of hw accel in kdenlive I'm still uncertain.
Thank you for your inputs.
