dvd render time

[Gilles Gagnon]

Hmmm… the estimate keeps increasing… it’s now 4.5 hours.
As I look at the preview window of what is being rendered, it looks like “less than realtime” as far as play speed is concerned.

I rendered for DVD a while ago and i’m sure it didn’t take this long.
Thoughts?

That kinda seem a bit too long, and seems to also be re-encoding
your media, as it shouldn’t since its already rendered as MPEG-2.

What Steve said. If your expected render time goes up like that, then DVDA is re-encoding the video file (and should have told you that it was going to). Did you adjust the bitrate in the “Render As” menu to get the MPEG file down to 4.3Gb? The default encoding parameters are good for about 75-minutes of DVD.

Thanks fellows, Perhaps I should be clearer.

The project is 1080i and I want to render the mpg and ac3 files to be used an DVDA to eventually burn the DVD. At this stage, my lengthy issue is with the render in SVP, I haven’t touched DVDA yet.

Project prop: 1080 60i, 29 fps
template to render: Main Concept mpg2,DVDA NTSC widescreen video stream. I changed to CBR 3400 (as recommended by the BitCalculator util)

render estimates at 5 hours! (and crashed after one hour. I swear I’ve rendered mpg2 before and it was much shorter.

Arggggghhhh! help!

The other thing that can cause a render time to increase (and the estimate is simply an estimate with little connection to reality) is the use of F/X. Some F/X will greatly increase render time because the encoder has to render every pixel of every frame. For example, bumping the opacity from 100% to 99% will be imperceptible to the eye, but it will add hours to the render time. Did you buy Vegasaur? It has an audit feature that may help – it will at least alert you to suspicious settings. Here is a screenshot of a test project I have on my desktop. I intentionally bumped the opacity of one event to see if Vegasaur Audit would see it.

I agree with Steve M very much. I’ve got into the practice of producing a lossless Lagarith MXF Digital Intermediary (D.I.) this gives me an archival-able and potentially further Final FINAL (!) and THAT renders well rapidly and less than real time. It’s worth considering.

DVDA also appears to be only single core aware, which adds to the DVD prep time. Run up task manager and you will see what I mean. I have had DVDA take 12+ hours to create a bluray iso!

Hi Stephen, I have Vasst Ultimate pro which has an audit util.
I just ran it and attempted a render.

After 2 hours or so of slow rendering, Vegas crashed again this time at 57%. Very frustrating!

Does anyone have any ideas aside from throwing Vegas in the garbage :)?

Hi Graham,
Pardon my ignorance but I don’t understand. DO you not render to mpg 2 for creating DVDs?

Gilles

[Gilles Gagnon]

Nigel,
The problem is not with DVDA… it’s with rendering to an mpg2 using a DVDA NTSC widescreen Sony Vegas templates. I don’t get as far as DVDA… I’m still trying to get the mpg2 file created… but can’t as described in this post.
