I have Studio 9 and Mulimedia Centre from ATI. My video card is an
All-in-Wonder Radeon. I also have MMC, MyDVD 4 and Pinnavle Studio 9 .

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 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 know my source quality is not excellent
so I wish to use the method that best preserves the quality I have.

Should I caoure usig MMC, Pinnavle Studio 9 or MyDVD4?

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?


Txs, Carlos

What looses the most quality is transfering analog video. You can usually
see the visable difference in quality drop when you make a copy of an analog
video tape. Usually transfering from digital video to digital video or
editing digital video does not loose visable quality. Changing the digital
video to a different compression format may or may not reduce much quality
depending on the compression type. I am not sure about the amount of quality
difference for converting digital formats but you can probably find out

Since the source (analog tape) is pretty noisy, you won't loose visible
quality with MPEG2. As for editing, as long as you restrict yourself to
simple cutting and pasting frames and maybe a fade-to-black, the frames that
are not being cut will not be recompressed.
