Dear all,
After some weeks I'm reporting back now concerning hardware accelerated
encoding on my Intel Haswell machine with HD 4600 graphics.
Detailed testing shows that (at least on this little older CPU ( ~ 2013)):
- hardware encoding with resizing is slower than software

Hello,
'kdenlive_render' accepts the parameter: 'preargs="..."' to pass
arguments to melt before any other (profile, consumer etc).
you can also run trials with 'melt' command instead of
'kdenlive_render', which is just a wrapper to send progress info &
controls to notifications, but is then a
Well, eventually I'd like to create a new render profile, but in order to find
out how it works (more precisely: why it didn't work), I looked at the render
scripts kdenlive creates; I thought it might be easier to learn it like that.
Whatever, it doesn't work as you proposed :-(
I think withou
Hi there, Bernd.
I am under the impression that you want to create a render profile in
Kdenlive. If that is the case start with the example from the bug report:
-vaapi_device /dev/dri/renderD128 -hwaccel vaapi
-hwaccel_output_format vaapi -i -an -c:v dnxhd
If you have a look at all the other ren
1) Proxy clips -- done
Proxy clips creation with hardware acceleration is working fine now, for the
record:
I use x264 with these settings (in ~/.local/share/kdenlive/
encodingprofiles.rc):
x264_vaapi=-vaapi_device /dev/dri/renderD128 -i -vf
format=nv12,hwupload,scale_vaapi=w=1280:h=720 -vcodec
Hi there, Bernd
Try again, but replace the "- $SOURCE_0 $TARGET_0" with "-i"
Kind regards,

Hi,
Foreword: I just did the upgrade to the testing package (17.04.3) to get this
"bug fix".
I'm really sorry, but I don't get it:
What you've sent me is the rendering parameter, as set in the render dialog.
You changed is from vcodec=hevc to vcodec_nvenc to get hardware encoding
working with
Hi,
Coming back regarding my attempts to get encoding using vaapi-hardware
acceleration to work...
First, Vincent, concerning your point of ffmpeg not being compiled with vaapi
enabled in Debian - well, that's correct and not correct somehow: it's not
compiled with enable-vaapi, but vaapi is s

Hi all,
Well so I can expect hw accel for ENcoding to work. What's about DEcoding? Can
that be enabled as well?
Is it correct that direct raw copying (no de- and re-encoding) is not possible?
Would be s nice (speedup & image quality) for all the clips which rest
unchanged! I know that this
Hello,
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 packa
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
ab=%audiobitrate+'k'
It would have been awesome if mlt and ffmpeg used th
