Hello all! Thanks for having me on the forum!
I am helping a friend to capture some footage; helping because I own many old formats, converters etc.
We're capturing live footage through a JVC gr-ax280 - we like the CCD sensor and the lens, it's got a look we enjoy.
When capturing through a cheap USB capture device, or through my Blackmagic Analog to SDI / Mini Recorder, there are lines present on the capture.
Laced, scan lines. Digital artefacts, I guess.
However, when I use Firewire instead, via my Sony PD150, those lines are not present.
The image without them is much more pleasing to us.
I'd prefer not to have to continue daisy chaining cameras to get the result, so would like to find another solution.
But I can't understand why we're getting such different results. If anyone has any ideas on what could be causing each outcome it would be super useful!
Thank you in advance.
@dellsam34, I'm mentioning you here because I've seen other posts of yours that indicate an interest in this area. I hope you don't mind!
Thank you!

The "lines" you see are a normal part of interlaced video. You don't see them with your DV caps because the player/editor hides them from you, by deinterlacing on the fly. The player/editor doesn't know your other caps are interlaced so it's not deinterlacing. When handled properly the "comb" artifacts will not be a problem.
Generally, capturing DV delivers worse quality than capturing raw video and compressing with a lossless codec. But it's a big subject. -
Thanks!
What's confusing is that using the same player/editor, the result is different with DV / other capture. But I'll look further into this, thanks
