hey, there's some ways emerging to do frame blending ln the frames OBS captures via a shader, very cool tech

a lua script: https://github.com/couleurm/smooth-mode/issues/2

download the gist and go in tools -> scripts, + button and select the lua file

an obs plugin: https://github.com/FiniteSingularity/obs-composite-blur/issues/100 download: https://github.com/FiniteSingularity/obs-composite-blur/actions/runs/11260570777 scroll down

both add a video filter you can put on your game capture sources

Hello I've done a simple prototype of frame blending, it captures last 6 frames and blends in shader You can replace float4 PassThrough(VertDataOut v_in) : TARGETto float4 PassThrough1(VertData...

I spoke to the dev of composite blur on the topic of having it capture at a higher fps than the output fps is set to, he said its not possible with a filter or heavy rewrite of OBS so not planned, but also said he had some ideas to make something like Blur which is performant for realtime

I think everything within OBS is pretty much running at the output fps, so everything it has access to and all the rendering stuff is built around that

#

But lowering the output fps seems like it shouldn't be too much. It's basically just dropping frames

#

And that streamfx claimed to do it but haven't figured that out yet

that wouldnt be ideal since you'd be blending every frame and only using a little portion of it

#

1/4th for 240fps, 1/6th for 360fps and so on

#

as much as it'd be a rough hack it's also the most probable we get working

slate merlin
#

I think that is ideal, at least for what I want

#

The goal is over sampling the frames and outputting less

#

Just blended into groups

#

I think the way the above ones work is just combining the new frame with the collection of previous frames, and they fade out by 0.5 each time (if the strength was 0.5)

#

So at a 360 capture, there would be some strength value where a frame lives on still visible for approximately 6 frames

#

Not precise, because a frame would be 0.5, then 0.25 then 0.125 etc as it just keeps getting blended by the same factor over and over

#

But you could approximate the strength to get it close

Woaaaa

idea: option in game capture source to blend every frame it captures

interesting

#

What needs to be done to make frame blending look like it's rendering at 30fps

#

or how else to configure it other than obs

#

sick i saw someone streaming that looked like they were using frame blending and i always wondered if it was possible in obs since

#

i got a hacky version by just creating multiple game captures and reducing opacity with a delay filter but that was so scuffed

#

ill def try this out

#

oh rip you cant lower the fps

#

need vfr capture 💔

ok

thank you!

This might be what merryz was using

#

Remember some guy said 2 years ago in this server that he was live streaming but was frame blending live

@slate merlin how do you configure temporal to make blur?
