4 k video stutter - activating directx hardware acceleration

[charbond]

I've been trying to use BORIS on a 4k video (mp4) and the video playback stutters somewhat badly. I think BORIS uses the same framework as VLC for playback, and I do have the same issue with these videos using VLC, except when I use the 64 bit version and enable DirectX Video Acceleration (DXVA) 2.0 hardware acceleration. I wonder if it's possible to active hardware acceleration in BORIS?

hello, thank you for reporting this issue. BORIS uses VLC library for video playback. I will check if it is possible to activate the hardware acceleration. For now if you do not need the 4k resolution you can try to re-encode/resize your video. You can do this using BORIS (Tools > Re-encode/resize).

Thanks for writing back so quickly! Hopefully it will be an easy fix :) Unfortunately, the videos were filmed in 4k because that was the optimal balance between area and resolution, so I can't resize the video without losing important details.
