Capture Card Sound Issue

[ZeldaN64]

So I had ordered an $80 capture card from Amazon and it came in today. I hooked it up and ran it through OBS and the sound of the game was garbly and kind of distorted. I'm running the game from an SNES, which the cable is connected towards an AV switch, that then goes to an AV to HDMI adapter, which is then plugged into my capture card and out to the TV, with a USB 3.0 connection. Is there any way I can fix this?

Problem half solved.

 

After plugging the device to the back of the computer, there was noticable differences, but this time the capture has a deeper tone and there are occasional hiccups.

You could get a 2 x RCA -> stereo jack cable and insert the cable into your sound card's line input and record it there.

 

I'm assuming you have a cable with 2 rca connectors for audio and a composite or s-video jack.

No it's the standard A/V cables (The red, white, and yellow cables).

Yeah, the yellow is composite video , white is left channel and red is right channel (if there's stereo output)

 

So you can get a 2 x RCA to stereo jack (TRS) cable and plug it in the line in of your sound card

 

ex: https://www.amazon.com/CableCreation-Stereo-Splitter-Receiver-Speakers/dp/B06XFQNFSS/

 

or with the female rca connectors if needed : https://www.amazon.com/UGREEN-Adapter-Compatible-Tablets-Computer/dp/B079L48B5G/

Also, you can get decent pci-e x1 capture cards from eBay, which support Windows 10 or worse case scenario, Windows 7.

For example this one is $8.5 plus shipping and there's drivers for it on the Hauppage website: https://www.ebay.com/itm/HP-5188-8538-Hauppauge-WinTV-hvr-1800-ATSC-QAM-NTSC-FM-78521-LF-TV-Tuner-Card/184013599423

You can use applications like Virtualdub to capture without going through several conversions (av input -> resize to resolution supported by hdmi -> analogue to digital (hdmi) -> to pc (possibly compressed to mpeg2 or mpeg4 on the fly by your amazon capture card) -> decoded back to a format OBS can use -> compress again

You can install a video codec like MagicYUV (free version) which allows you to capture in real time at lossless quality, then you can open the video with a program like MeGUI and choose to compress that to MP4 or MKV (h264 codec).

Alternatively, you can install XVID codec and choose to compress in real time using xvid codec... for the resolution the snes outputs, xvid is more than enough to get very good quality.

Well, the thing is, it's not just the SNES I'll be live streaming from, it's also NES, N64, GCN, PS, Xbox (Original), PS4, and Wii U (and at some point an Xbox 360), the capture card is the kind with an HDMI in and out, with a little USB 3.0 at the bottom. Not to mention, my computer is a Micro ATX, so there may be some clearance issues with the other things I have.

[mariushm]

then even better... a proper analogue capture card would work much better for streaming, if you can get one with drivers for windows 10.

For 10$ I'd say it's worth buying one to play with it.

at the very least it would allow you to capture those analogue signals at a resolution closer to the native one, instead of being upsampled by the analogue to digital converters and the hdmi encoder chip etc etc

If the drivers work, these will show up in OBS like any capture card / device... i was just suggesting Virtualdub if you want to capture losslessly, for archival or for editing later and making Youtube videos.
