[ouni666]

I found this commit and it caused an error afterwards. 8ddaec7

• Linear 10‑bit GPU/CPU (Experimental) mode. ❌
  The mode I am currently using
• Native 8-bit CPU (fast and flexible) ✅
  Using this mode, the video output is successful.

The version of Shotcut being used: v26.4.30
The version of MLT being used: v7.38.0

This is error log

[hevc_vaapi @ 0x7efe74201780] A hardware frames reference is required to associate the encoding device.

failed to find hw_pix_fmt

hevc_vaapi is not working. Turn it off in Export > Use hardware encoder > Configure. Then, click Reset because changing the hardware encoder configuration does not immediately change current export settings.

For 8-bit it is using h264_vaapi hardware encoder, which is working. H.264 hardware encoders do not generally support 10-bit. Alternatively, if you want to keep hevc_vaapi enabled for some reason, choose a compatible 8-bit export preset such as H.264 High Profile when using a 10 bit processing mode.
I will probably not make a change from this bug report.
