I already saw the topic here:Can AMD APP (VCE) encode in higher chroma subsampling? , but since two years have passed, I hoped that there could've been some change.
I personally have an RX 480, but a colleague has a Vega 64 and I'd be interested to know if the new VCE version included on there has got the possibility to record without chroma subsampling.
Are you by any chance using OBS software. If you are then this website may be helpful: GitHub - Xaymar/obs-studio_amf-encoder-plugin: AMD Advanced Media Framework Encoder Plugin for Open ...
See if this website on AMF is helpful: https://gpuopen.com/gaming-product/advanced-media-framework/
Thank you for replying.
I've looked through these links, but found nothing mentioning possible to be used chroma schemes.
I do use OBS Studio, but with the default plugin for AMF (I think it was forked from the Xaymar's version). While I have configured the colorspace to either RGB or I444 in the advanced settings + 709 set to full space, it still comes out as 4:2:0 chroma after the recorded video is saved.
Thus I thought there could be some sort of limit, since the encoder's settings do not have settings for the colorspace nor chroma.
