Capturing Video at 60 FPS But looks More Like 30 FPS

[AK1982]

Hello All,

I'm new here and I want to post a strange issue I'm seeing. I bought one of those cheap HDMI capture cards on Amazon that promises 1080P/60 video capture. I connected my Switch to the HDMI IN, HDMI Out to the TV and the USB Male to Male to the computer right? I have a MacBook Pro M1PRO.

The image looks great o the TV 60 FPS and all, but on OBS preview window and recorded looks choppy. OBS tells me the input is at 60 FPS on the bottom right and when I check on Quicktime for the Info or VLC it alo tells me its running at 60, but I know what 60FPS looks like that video looks more like 30. I can also tell the difference since the Image on TV look much much smoother than on the recorded video. Sometimes It look like by setting the video tab on OBS settings to 60 FPS im forcing the 60 FPS to be recorded even though the source is coming at a lower frame? is that possible?

Could this be this cheap capture card or maybe the USB male to male cable coming from the card to the computer?

I posted a video on YouTube for a small section of gameplay. Even YouTube says it’s 60 FPS but you can it does not look like 60 FPS

Is the original signal interlaced? Interlacing draws all of the odd lines of one "frame", then all of the even lines of the next "frame", then all of the odd lines, etc. So you might get 60fps...sorta...or 30fps, depending on how the de-interlacer works.

Interlacing is usually good enough to fool your eyes - it's designed specifically to transmit half the data without flickering - but it causes problems for things that require a complete image for every frame.

At any rate, you can't add any more useful information than what you actually capture. So if you capture interlaced, that's all the useful information you've got. If you try to improve it, sure, you can add bits all day, but none of them are useful. Everything you add to try and improve it, can only be redundant.

No it’s not, signal is 1080p. It’s coming from a Nintendo Switch

The image is butter smooth on the TV but on OBS is not, even tough OBS says it’s 60 FPS. I posted a video have you had a chance to watch it? The image look good but it’s not smooth especially on the part that Mario is running.

Yes, I did, before I commented. I can't really tell, to be honest. Looks fine to me. Nothing moves fast enough to *need* 60fps.

Though it could just be that I'm not a Mario connoisseur, or that I saw it originally on an interlaced TV and so "that's what it's supposed to look like" for me.

I gotcha… yeah I was playing on the TV while recording so I can really tell that on OBS is not quite smooth you know.

I’m wondering if it’s just the quality of the capture card or even the USB cable.

I even tried on a different computer and the result was the same.

1. Is your Switch docked when you are doing this?
2. Does this happen you connect the Switch (while it's docked) directly to the capture card?
3. Post a log.

Include a log file if you have a problem: here's how

To upload a log file, go to the Help menu -> Log Files -> Upload current/last log file. The current log file is for the currently active running session. The last log file is for the last time you ran the program. We recommend always including it just in case.
