Analog to Digital Converter "RED" Problem

At this time, I'm using a Sony Handycam (via Firewire) to convert my Laserdiscs to DV for making my DVD's.

The big problem I've been having is with the color red. Whenever red is shown in the video, I can see lines or block looking patterns in the red part of the images. I have a feeling that it is the Sony Handycam doing this. Do any of you know about this type of thing? If I was going to replace my Handycam with another converter, what should I get?

Thanks

I can't tell you what you should get, but the red problems are because of the MiniDV format.

I used to be very active on this forum. I’m not really anymore. Sometimes, people still want to get in touch with me about something, and that is great! If that describes you, please email me at [my username]ATgmailDOTcom.

Hi everybody. You’re all awesome. Keep up the good work.

So that Handycam is the weak link!

Now I was thinking of a Canopus ADVC-110. It's under $250, and I can't spend hundreds on this.

The DV codec you're capturing with is the weak link. The Canopus will still suffer from the same problem. Reds and blues do not like the DV format. Or is it the other way around?

You can go about your business. Move along, move along.

The problem occurs because NTSC DV uses 4:1:1 chroma subsampling, and DVD MPEG-2 uses 4:2:0 - you end up with a low resolution for the chroma. Reds and blues are the most obvious.

I haven't used NTSC DV myself, but I understand the solution is to use VirtualDub's chroma smoother filter on the video before compression to MPEG-2.

I also use virtualdub's chromasmoother. In some PAL captures I also have this problem (in lasers) and when I use virtualdub's chromasmoother (4:1:0) it's completely gone, but I don't really know what 4:2:2, 4:2:0, 4:1:0 etc. means so I don't know if it affects the video quality.

The PAL 2004 Star Wars dvds also have this problem (maybe many more dvds but I never noticed it).
