How to deinterlace SNES video for PC play/capture?

Question

I have an original SNES. I'm trying to output video to my pc, using the component output. I'm using a Diamond VC500. I got the latest drivers ("VC500 Complete Package" from that page). Main issue: the video is showing up weirdly interlaced:

As a side point, I'm not sure what software to use to view the capture stream. If I use VLC, there's a noticeable input delay I can't figure out how to fix. If I use the EZ Grabber software that comes with the capture card, there's no video shown but the screenshot tool works (how I captured the above image):

If I use OBS, I can't get the audio to work.

Anyways, the main question is: How can I capture SNES video to PC without the weird interlacing?

Windows 10 Home, GeForce GTX 980 Ti.

edit: I found this related question, so I'm assuming my question is appropriate for this SE: How can I play a SNES through a VGA monitor?

I've found some useful information in the following posts:

https://obsproject.com/forum/resources/capturing-streaming-your-retro-consoles-the-right-way.289/

https://www.reddit.com/r/speedrun/comments/2fvcy6/snes_capture_scanlines/

Both of these mention using some software called amarectv. It seems it was last updated in 2013, but this works on Windows 10.

Here's a screenshot of it the output, the interlacing issue I posted about is no longer present:

Some notes on the setup:

I downloaded the software and unzipped it, filename amarectv231_en.zip.

There are a few different executables, I just ran AmaRecTV.exe.

Here's a copy of the config, this is the only tab where I changed anything:

Text overview of settings:

• Video Capture Device: Conexant Polaris Video Capture (only option)
• Audio Capture Device: changed to Conexant Polaris Audio Capture
• Input: changed to composite
• Audio input: changed to (link)
• (I'm in the US, using the 29.97 fps options)
• Format (top/video): changed to *w= 720, h= 480, fps=29.97, fcc=UYVY, bit=16
• Format (bottom/audio): chose *sample= 48000, bit=16, ch= 2 (only option)

A note on the format, the 360x240 options (*w= 360, h= 240, fps=29.97, fcc=YUY2, bit=16) are still badly interlaced. I can't tell a difference between UYVY and YUV2
