Transcoding to H264 drops fps to zero

PostFri May 19, 2017 1:28 pm

Mac Pro 2013
OSX 10.5.5
Davinci 12.5.5
GPU Processing mode Open CL

Basically when I start the rendering to H264 the fps speed fluctuates between 60 to 0 constantly, making the render reaaaaally slow

Thanks a lot!

Why not render to a high quality codec to have a master file and later transcode to H.264?
Quality of some other transcoders is better anyway.
No, an iGPU is not enough, and you can't use HEVC 10 bit 4:2:2 in the free version.

Definitely try Handbrake to transcode from a HQ codec (ProRes) exported from Resolve... Forget about doing it in one action in Resolve.

What would be a good high quality codec to render to for windows users?
Windows 10, 64 Bit
i5-13600K
32GB DDR4 Memory
RTX 2060 SUPER 8GB VRAM

DNxHD/Q is like ProRes but easily available on windows.
