DVD Lock up

[Mayer]

Hi all

This little problem is getting me down. I am reasonaly comfortable in creating my own DVD (using premier pro) and have not had any real problems in the past but this issue has just stumped me.

I have compiled approx 40 short sequences of dv avi files to the timeline and the length of the compilation is about 1 hour 44 minutes. I have selected burn to dvd using the PAL seting with vbr (2 pass at 4mb). The finished dvd (after nearly 10hrs encoding) is great untill about three quarters through the movie when it starts to freeze.

I know it sounds like bitrate starvation but I have twice now done the job, once with bitrate set from bitrate calculater and once with default settings but it still freezes around the same time.

Any ideas on where I should look now???

Is it only freezing on the DVD? Can you save the DVD to your Hard disk and play from there OK?

If so then it may be the media.

Freezing does not sound like bitrate starving, that'd still play but would look bad, Maybe macroblocking, Gradient objects would be blotchy. By that I mean if not enough bitrate a scene that started out in white at one part and went to black gradually would not look good. Sort of a sunset type of scene where instead of a smooth transition it'd show abrupt changes in color if I'm being clear enough. So I'd start with media or burner going bad. Most likely media, did you change brands or spindles of disks?

Try outputting it to the hard drive and playing it there as a first test. If still bad there, then it may be your source AVIs. If ok there look at the burn to DVD.

Good Luck

Thanks for the quick reply, thinking back what you say about bitrate is probaly right. I have not changed brands at all, and the disc plays ok on the PC.

any other thoughts?

[Mayer]

OK,

Now using a Sony DVD RW, quality disc and it still does it around the same point. Have also encoded the full timeline to Mpeg2 and ran that on media player and it seems ok.

Tried as Divx but the audio is out of sync.....

I am giving up on this lark, there must be an easyer way to get your home movies simply to disc...

MEDIA

[Mayer]

yup

looks like media and burner...new hardware coming up

As you said, "there must be an easyer way to get your home movies simply to disc..."

The truth is, it actually is. Assuming the PC is able to handle the work involved and BTW it is the most intensive type of work you can ask your PC tp perform. Assuming that the program is competent and presumably Adobe Premiere is, then the problems have to lie somewhere bettwen your burner, Media and player. Now, if I understood your first post correctly, do you let Premiere out put your edit to DVD directly? If that is the case I would instead out put to MPG2 and then author my resulting MPG2 file PAL or NTSC to DVD usning a dedicated authoring prog. Good media like TY or Verbatin should at least eliminate the media as a variable and you need to try your finished disc in several machines. You may possibly find that your machine simply does not like the media you may be using.

Reckon I will dabble with that tonight, I have outputted to a Mpg2 which is currently 23gig, to my hard drive. I think I will author it with Canopus Procoder and see what happens there, on a different media type that is.

[jtoolman2000]

How can an MPG2 be 23 gigs big. Just how many hours long is it?
Sure it is an MPG and not an uncompressed AVI? Also unless I am totally wrong, I though Main Concept was an MPG encoder and not a DVD authoring tool. You would use it to encode a raw avi or DV edited file to MPG2, an hour's worth would be around 2-3 gigs depending on bitrate setting, which would then be authored to DVD in something like TDA, DVD Lab, Adobe Encore and simmilar software.

[Mayer]

hehehe

Sorry

It is 23 gig avi, did it this way so I could see how procoder encoded it.

[Mayer]

Damm, its all gone wrong again.

This is what I have done now. Loaded the raw avi into Procoder, selected DVD (VOB) output, selected my destination folder for the vob's and left the pc for six and a half hours.

Returned this morning to a smoking pc and "eh whalla", there are my vods ready to burn.

Open up nero and choose dvd burn, loaded the vobs up and would you guess it....Procoder created nearly 4.8 gig of dvd, which will is too much to get onto Nero.

Any one got any suggestions or am I missing something simple here???
