View Full Version : General Advise about DVD authoring

Hi,

My purpose is to capture my homevideo and author it with DVD Maestro.

Could someone give me some general advice (I prefer details like settings and stuff.)

At the moment I capture from my analogue camera using virtualdub 1.5.4. with Divx Pro 5.03 codec as compression. My 40 minutes avi equals to a size of 400 mb. After encoding with DVD2sVCD (encoder = CCE 2.50 output = m-peg2) I end up with a file that contains 6 gigabyte of data.
Somehow the filesize speed goes up form 2.2 to 28. My frame speed drops to from 1.200 to 0.445. I really doubt the fact that a 40 minutes analogue capture turns out to be 6 gigs encoded video. Even films of 1,5 hours turn to be 1,6 gigs. how is this possible.

Could someone please help?

U have encoded at a very high constant bitrate. U should re-encode at a variable bitrate (vbr) at max 2300 min around 100 and average 1800. That should suffice for your encode.

If you want the best quality and you have plenty of space I'd recommend you use a lossless or low loss codec (like maybe HUFFYUV) for capturing rather than something like DivX. Then when you reencode into MPEG-2 for DVD you aren't doubling the chances of distortion...

Hi,

I capture my avi using virtualdub v1.5.4. I use DivxPro 5.03 Portable Profile (set to 304 kbs). I have not tested the material on my TV. The max bitrate = 768. I don't know if it's acceptable. But for the 40 minutes of capture I end up with a 400 mb filesize. If I say that many divx movies take 700 mb for an 1,5 hour, so I guess I use a common standard. But I won't know before I tested the thing at my widescreen.

I want to thank oddyseus for his advice. @ jddobs Thx to you too, but I am not that power user. It's a bit struggling. At first encoding takes much longer. My 40 minute footage took 1,5 hour to encode. After that I ended up with 6 gigs of data. For people who really want to do this it's sure takes more time than with compressed data. I used your method with the little parts of my footage. Like 2 minutes or 6 minutes lenght. After encoding I endup with a filesize round 60 mb. Which is nice according to my situation.

But so far I have not tested the whole. But if I am done I will post it. I hope there won't be too much difference.
