keen456,

@artandtechnic Here's a still from a VHS capture I did. What is that band of noise at the very bottom (approximately 4-8 pixels tall, and doesn't seem to be tape-specific as it shows up regularly), and what's the best approach to getting rid of it? Thanks

@keen456 Looks like head-switching “noise” - which is nothing to be concerned about, it’s normal. If you capture the full-height of the recording, at 486 lines (which includes the captions at the top), you’ll see a bit more of that at the bottom of the raster.

How much you see depends a lot on the VCRs used for recording / playback.

It tends to be especially prominent with early Betamax decks, and the Quasar Time Machine (which actually blanked that part of the raster).

@keen456 Since that part of the raster is well outside of ‘safe action,’ it wasn’t a great concern at the time.

@keen456 On non-captioned recordings, you can capture full height (720x486), and reposition your export so that you’re extracting the top 480 lines. Essentially, cropping the bottom of the frame off. While this sounds stupid, it can work incredibly well.

On captioned recordings… you’d have to see about blanking the very bottom of the frame. This feature goes by various names in various programs. I think it might be called ‘padding’ in Compressor (not sure, haven’t used it for that).

keen456,

@artandtechnic Okay- that's pretty much what I did on my recordings. Thanks so much for the insight here!
