From your logs I see that you have a AMD graphics card. Your card only supports hardware accelerated encoding for h.264 codecs. It does not support HEVC/H.265
AMFVideoDecoderUVD_H264_AVC
→ AMD H.264 Hardware Encoder Detected : True
→ AMD H.265 Hardware Encoder Detected : False
→ AMD AV1 Hardware Encoder Detected : False
However the profile you’re using to convert is MP4 HEVC. HEVC is a very CPU intensive codec format. Since your hardware doesn’t support HEVC encoding the CPU has to do it and you have a very very fast CPU otherwise it takes a long time to complete.
→ Profile being used : MP4 HEVC
If you want to speed up your conversions you have 3 options:
- Use the MP4 Normal or MP4 High Quality (h.264) profile. This will use your graphics card hardware acceleration and speed things up significantly
- Get a new graphics card and which supports HEVC/h.265 if you want to use the current profile
- Reduce the quality slider to -50% or more. While this will speed up the conversion, the quality will also reduce.
