Capture Card recommendations for fast sync speed with OSSC?

[Xerxar]

Hoping someone can give me some advice as searching ha proven fruitless. Currently I have a functioning setup but I'm unhappy with the speed my capture card syncs which my OSSC. It takes anywhere from 7-10 full seconds to get audio and video which is completely unacceptable from a speed-running point of view as some games require resets during a run not to mention time lost waiting to start fresh runs in general.

My primary focus is on an RGB modded NES and SNES. They both have de-jitter mods and work great to my display. Current capture card is an internal AverMedia Live Gamer 4k. I've tried everything i can think of at this point to improve the sync speed including: Different HDMI cables, direct connection straight from the OSSC, modifying OSSC settings and profiles, using an A/V receiver in between and doing the de-jitter mods. Nothing seems to help which tells me I need a different card.

I can not seem to find any information on this specific metric when it comes to capture cards so i'm hoping to find some help here. What kind of delay is there to regain video/audio from the cards some of you have when you hit reset on a console? 5x capability would be a nice bonus but I can live with 3x or 4x.

You don't need another capture card, you need a secondary scaler that can normalize and bridge the two different output signals you get from the OSSC when your source is switching between 240p and 480i output.

According to some review, this one should work for you:

Gets connected into the HDMI stream between the OSSC and your capture card.

The StarTech USB3HDCAP has little to no syncing delay, even when rapidly switching between 240p and 480i. The SNES needs the de-jitter mod to work at 5x, and for some reason my NESRGB 2.0 is only stable at 4x even with the de-jitter firmware, but everything else I've tried works fine at 5x. I did have to set the HDMI bandwidth to 125% in the settings, though.

Hmm so I would need to do OSSC > splitter > scaler > capture. My only concern there is that I even see this delay when hooking up a modern device, such as a laptop, Switch or PS4 so I fear this card just takes forever to sync no matter what.

That sounds promising, I believe one of my local friends has one of these, think i'll see if i can borrow it to test with.

Thanks for the responses guys.

from your capture card's point of video, the signal no longer drops once you have the secondary scaler in place.

Oh i see, so you are saying the brief interruption in signal from doing a console reset wont be noticed by the capture card with a scaler in place? interesting. Can't hurt to try it, can always send it back

If that SCART to HDMI normalizes via the HDMI passthrough, I wonder if there's another HDMI->HDMI processor that could also be used? If someone could with a Darbeevision could confirm that those help with 240p<->480i, then people would be able to spend their hard earned money on something a little more useful

Most seamless switchers should be able to do so, e.g. the IN series by Extron (IN1606 and others).

Have you tried any of those oldddd Inline scalers, that company that (I'm assuming) Extron absorbed + kept the model numbers from? I see them on eBay all the time and am a bit curious, but I doubt I'm missing much. I've got a GBS8200 modded with CFW & a decoder to get composite and s-vid sources into it if the need ever arises, so I'm assuming it's made most older scalers obsolete for me, as far as video games go.
