Can DV be authored as SVCD in a DVD-R?

[Drylook]

I have the possibility to capture DV via firewire...

The question is if I can use a DVD-R big storage place to put a SVCD?

I'm using my mini-DV camcorder as a signal converter from analog to digital and VHS doesn't need the bitrate you will put as DVD.

I don't think you can burn a DVD-R as an SVCD, but who cares? What you intend to do is to get more stuff on the medium without wasting bits. All you need to do is to author a regular DVD, use a DVD resolution like 352x576 or 720x576 (these values are for PAL), and encode at a low bitrate like 3000 kbps or even less (2520 kbps is often used for SVCDs).

Well bb,
I've tried with a bitrate of 3000 and the result is fuzzy compared to the original.

I'm just putting my old VHS tapes in DVD but I get the feeling I'm wasting a whole lot of space...

I'm capturing at 720x576 and 3745 KB/s (that's what Pinnacle Studio calls Total Video Quality). Pinnacle doesn't know I'm using the Dv Camera as a bypass from analog to digital. For the software I have a Dv input so that's why the capture goes like that.

The result is a avi file.

After some work on the file, I can create a mpeg-2 file and that's when i'm going to choose the format. It seems that selecting a bitrate below 6000 doesn't look good at the end...

My idea was to use the DVD-R space (4.7 Gb) as a SVCD or something similar. That way I'ld be able to squeeze some tapes onto 1 DVD without loosing quality.

The question is How?

My guess is that I'm stuck with a High Quality input (higher that the original tape) and any attempt in decreasing bitrate or a format lower than 720x576 will result in loosing quality.:(

In my experience in similar VHS projects so far, they always seem to require a higher bitrate to retain quality due to all the artifacts from older vhs tapes...the only way arouns it I have found so far, is encoding it in half d (352x480 for ntsc) and using a noise filter during the encodeing. If you have a smaller horizontal line res on your dv cam, squishing the res in half makes the lines more noticeable afterwards it seems though. I've been getting about 4 hours onto DVD with HQ so far though.

Is it necessary to use DV as intermediate format? For highest quality I suggest to use Huffyuv, captured through video-in (or even better s-video). Then apply Convolution3D, resize to 352x576 (or 352x480 for NTSC), and encode to MPEG-2 at low bitrate.

If that's not an option for you, stay with your DV method, but use Convolution3D and the resizing as well. You can try other filters, too, like Flaxen's VirtualDub VHS filter.

I have an old WinTV and I also rather use my Sony camcorder for A/D conversion of video tapes - the quality is much better that way.

Drylook,
if any DVD bitrate below 6000 looks bad, then SVCD won't look any better! To make your video look better at that bitrates, make it progressive (=deinterlace first) and use a good filter like convolution3d before encoding.
Basically just do what bb said before :)
