SUMMARY I'm not able to change the encoding profile for proxy clips. I have an older GPU that Ubuntu 20.04 has been holding back versions of upgrades. When I enable proxy clips, Kdenlive appears to be only selecting h264_nvenc. If I set it to regular h264 or automatic the detailed log is always the same message with the warning about h264_nvenc. STEPS TO REPRODUCE 1. Enable proxy clips, set profile to any profile that should be compatible with the setup (I've tried h264, mpeg2, and automatic). 2. Click apply (issue also happens if I restart Kdenlive after this step) 3. Open existing project 4. Right click on a clip and select proxy clip OBSERVED RESULT Kdenlive shows a message that the proxy clip failed to create. The message always indicates that it tried to use h264_nvenc. EXPECTED RESULT I expected Kdenlive's automatic setting to use a different encoding profile if the driver for nvenc is too old. I also expected that Kdenlive would use any other encoding profile that I selected. I've seen this issue on the stable from Flathub as well as the latest stable appimage (21.11.70). Below is the information from the appimage. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Ubuntu 20.04 KDE Plasma Version: Unknown (not sure where to find that in the app since I do not see an about system menu item). KDE Frameworks Version: 5.81.0 Qt Version: 5.14.2 (built against 5.14.2) ADDITIONAL INFORMATION Detailed log from Kdenlive: [h264_nvenc @ 0x180a640] Driver does not support the required nvenc API version. Required: 11.0 Found: 10.0 [h264_nvenc @ 0x180a640] The minimum required Nvidia driver for nvenc is (unknown) or newer Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
I've found that I can only get the proxy clips to work on brand new projects where I already have Kdenlive setup to use the right encoding profile (in this case selecting x264).
Can you please try with the latest version and see if you can reproduce?
