OBS (Studio) VCE

hey - if you want to stream with AMD VCE you should stick to the OBS VCE fork

https://obsproject.com/forum/threads/obs-studio-amd-vce-bitrate-problem.45454 shows the problem with Studio - but a Dev said its still in an experimental phase and not to use for STREAMING yet.

you can record with it - what looks great, but if you want to stream you still need OBS VCE fork (https://obsproject.com/forum/threads/obs-branch-with-amd-vce-support.13996/)

you can use my settings with most GCN 1.0 (or higher) Cards for 720p30 (i use HD7970) and just have around 5% CPU load

here 2 examples

ps if you have a newer card you can improve quality even more (i have to upgrade when Zen arrives)

Re: OBS (Studio) VCE

Hey Benman. What would I use to Record 4K @ 60 fps and upload to Youtube. I want to upload some Dota 2 games to see how good 4K looks. They recommend 53-68 Mbps. Will I be able to do it with a 3770K @ 4.6GHz + 290X? Currently I get over 80 fps in the game.

Re: OBS (Studio) VCE

290X has a encoder limitation of +/- 1920x1080 with 30fps with quality preset and 1920x1080 with 60fps for balanced or speed preset.  the downside is the current API used in OBS Studios does not allow to change the preset through MFT (Media Foundation Transforms). This is true for GCN 1 and GCN 1.1 cards.  GCN 1.2 (Fury/Nano/380(x)) should allow to break through this barrier to allow for 4k @30fps encoding but I have yet to see this work with VCE. 

TL;DR you will need to use x264 as a fallback for 4K@60fps and at that, I doubt your CPU will be able to handle this even at ultrafast x264 preset. I would shoot for 1080@60 superfast x264 preset and use a 0 buffer.

Re: OBS (Studio) VCE

sry i missed it - you need a GCN 1.2 card to record in 4k30

try OBS VCE fork for 1080p60 balanced https://obsproject.com/forum/threads/obs-branch-with-amd-vce-support.13996/

and try these custom settings:

OBS_VCE_encoder_settings_IPP6.jpg

they CAN be choppy with 1080p60 because these are some balanced-quality-mix settings -> but i can help you to improve them

BUT you have to change minQP to ~10-15 & maxQP to ~25-30 -> will directly improve video quality but takes more bitrate

bitrate for 1080p60 on youtube should be around 28-30Mbit and no custom buffersize to look awesome

audio bitrate depends if you want to add music while gaming or later - but for not streaming 160kbps aac should be enough

Re: OBS (Studio) VCE

i am having some issues with using VCE also.  so it is true that i can not use the VCE to record in 1440p with my 290X, i dont see why this would not be doable.  is it just a limitation on the hardware itself?

Re: OBS (Studio) VCE

there is something in the make for OBS Studio - Releases · Xaymar/OBS-AMD-Advanced-Media-Framework · GitHub

but its under dev right now - will take some time

Re: OBS (Studio) VCE

Do you know roughly how much up speed I would need for 1080p 30fps streaming?

Re: OBS (Studio) VCE

7000kbps minimun to look ok

but twitch only allows you 3500kbps

so on twitch 720p30 or 720p60 (but better 30fps) run "ok"
