AMD Encoder always fails to export for 5k footage

PostWed Sep 18, 2019 2:02 pm

In the deliver tab, when trying to export a video of resolution 5760 x 2880, with the Encoder set to AMD, the process always fails. It will start to render, but after about 30 seconds a notification comes up saying that the render process failed. This is happening on with format MP4 for both h.264 and h.265 codecs. When switching to MP4 h.264 with the "Native" Encoder, the render process works fine. Due to this I am not able to export videos in h.265 at this resolution. For 4k resolution the AMD Encoder works fine.

My system is:
- Windows
- 2700x CPU
- VEGA 64 GPU
- Davinci Resolve Studio 16.0

Any help would be greatly appreciated.

Well, your resolution is obviously beyond 4K in all aspects. AMD HW encoder works up to 4K AFAIK.

30 second delay is probably the time before rendered frames are sent to the encoder which then fails.

Thanks for your reply. Yes, the video I am looking to encode is larger than 4k. I was unaware of the AMD HW encoder limitation. Do you happen to have a reference to this? Is this something that AMD should be able to fix in an update?
