Composite VS S-Video

[GGuyZ]

Hi everyone.

I am using Canopus ADVC 110 to capture my VHS/hi8 tapes. The DV format is a temp solution, since like many I then edit, clean, and encode as mpeg2 for DVD.

While I do have S-Video connection on my hi8 camera, when trying to capture my VHS tapes I have to use composite.

I do not wish to buy a different VCR, so I was wondering what are the quality consenquences to using composite over Svideo.
I am capturing PAL footage and I intend to keep it in PAL all the way.

With Regards,
Guy.

with VHS and Video-8 Composite is fully sufficient, because the luma bandwidth of VHS or Video-8 never exceeds the embedded chroma signal. So both signals don't interfere here.

With S-VHS or Hi-8 you have to use S-Video in order not to loose image quality. Hi-8 and S-VHS have a much greater luma bandwidth.

Thank you for your quick reply.

However, I didn't refer to the bandwith.
I heard capturing with composite may create many new issues that don't exist in the original VHS tapes.
Such as: rainbows, color bleeding, 'chess like pixels'(forgot the name... comb artifacts perhaps?) etc...

Could anyone please tell me whether this is true, and which quality diminishing 'side effects' I might encounter if at all?

These artifacts won't appear with VHS or Video-8 due to their low luma bandwidth.
You won't lose anything when capturing VHS over composite compared to S-Video.

So this statement

is not correct, cause high bandwidth cause the artifacts you are mentioning.

edit: changed Hi-8 to Video-8

Per "scharfis_brain"Hi-8 and S-VHS have a much greater luma bandwidth.
Per "guldukat"These artifacts won't appear with VHS or Hi-8 due to their low luma bandwidth.
You can't both be correct regarding "Hi-8" - so who's right?
