Does MPEG editing lose quality?

[CarlosWA]

I will be capturing from VHS (18 hrs), editing the video and producing DVDs for home viewing of family recordings. Should I capture on MPEG-2?

I understnad MPEG is a compressed format. Then when I edit the captured video will I loose quality because the video may be compresed again?

I just want DVDs of reasonable quality. My VHS tapes are a copy made from my analog camcorder tapes (which have been reused for late recordings).

I have Pinnacle Studio 9 and Mulimedia Centre from ATI. My video card is an All-in-Wonder Radeon.

Txs, Carlos

No.
However if you convert to raw video, edit, and re-encode back to
MPEG2, you will lose some quality.
This is what most NLE s will do. Premiere etc.

MPEG2VCR does not re-encode , but has limited editing


BTW don't worry too much about quality. It's already gone
form the VHS step
