Quick question (interlacing)

[Bio]

Hi all,

I'm in the process of archiving old family VHS tapes to VCD (both PAL) via VirtualDub frameserving to TMPGEnc, everything on that front is fine.

As the source is interlaced (shot from an old camcorder) and i want to watch the final product on TV, am i correct in assuming i should avoid de-interlacing in post processing?

Thanks for any advice. :)

Depends on the desired target format:

For MPEG2 I wouldn't deinterlace, because MPEG2 supports interlaced frames.

For DivX or XviD you should deinterlace, because these codecs need progressive frames as input.

you would get better answers at forums regarding vcd/svcd since, deinterlacing isn't done while capturing, but rather afterwards, while encoding.


VCD has a small frame size, and it doesn't support interlaced stuff. so u'll have to de-interlace for VCD.

SVCD however is a completely different matter. it supports interlaced content, and basically u would leave your content interlaced, and it should look fine on tv.
u should notice which is the "top" field.

i suggest u make several short (about 1 min) mpeg files with various configurations, burn them all to a single cd (yes it's possible, and you'll be able to choose which one to play during playback)

write down the best configuration, and go for it ;)

good luck.

My Dad's DVD player is a rather old and crumbly and doesn't like SVCDs, as he's the intended recipient i'll probably stick with VCD (MPEG-1) and de-interlace away.
