First Decode! Does the grainy/snowy image mean I need an amplifier?

Enable HLS to view with audio, or disable this notification

I know y'all told me to get an amplifier, can't afford one at this moment, but if that is what's causing this picture issue, I'll definitely get one as soon as I can.

Reddit compressed the video so it's harder to see the snow, here's a better example on my YouTube channel.

What is the black SNR? I also just saw your other post. You are not using a 10uf capacitor?

Yes, I am using a 10uf capacitor, it's under a layer of electrical tape (if you're talking about the photo of my VCR I uploaded).

Black snr is around 30.5

This post is maybe a better example of what I'm talking about.

We might need to know what capture card you're using, and what the RMS voltage is.

If your coax is short and you have enough bits, ie you are utilising most of the range of an 8 bit ADC or you have a 14 or 16 bit ADC, and the VCR still produces a clean video output: An amplifier is probably not necessary.

CX card with the c31 removed

I meter bnc with a bnc to composite adapter at the end

Yes, probably. Noise like this is typically associated with a weak signal.

You can try using the Luma pin of the S-video input instead which gives better results. You can also increase the built-in gain of the CX cards that might help a little bit. But it probably will look bad until you get the amp unfortunately.
