Hi!

I'm really new at this so hope you can help me with these noobie questions you have heard all the time.
I have both a Pioneer HLD-X0 and HLD-X9 laserdisc players. I want to capture frpm these in best quality I can.
So what settings should I have? Should I go for RGB24 or YUV2? NTSC-M? What more?

I also wonder why I get strange chroma noise when I look at a frame that I do not get when I see the LD live on a big screen?

Everything you could help me with would be great.

Thanks in advance

Here is the problem I get:

It is usual to use the YUY2 format for capturing. This is a PC storage reference to YCbCr with 4:2:2 subsampling.

Most regular capture cards use this format internally, so there is no benefit in choosing RGB24. The results will be identical, and RGB with huffyuv is slower and does not compress as well.

However, as the PDI Delux is a bit more than your regular capture card, it might be worth a short test to see if there is a difference. Some colour correction operations, and post-processing with VirtualDub, require RGB format, so capturing in RGB would save one conversion step.

I would assume you should use NTSC-J for Japanese discs, and NTSC-M for US discs. The only difference is in the black level, which is a lower voltage for NTSC-J.

The artifacts shown in the screenshots look like rainbow effects (aka cross colour - hi-frequency luma data upsets the chroma demodulator). It's caused by imperfect separation of the luma and chroma components of a composite video signal.

Thanks!

About thr black level. Almost all LD's are lighter in black level. Is there something I should set in the card or is is something to do after the capture? 640x480 is the right size to capture?
Are there anything else I should change in the settings?

Thanks in advance

My own approach was to set brightness and contrast in the capture settings, so I didn't need to adjust anything in post.

I remember posting an example image in the Star Wars preservation section, I'll see if I can find it again.

If your final desired format is DVD, then I would capture at 720x480.
