Thank you for your answers. Wat Roger stated is not my exact problem, still a good point though.

@Bob, this could be possible, but will be a LOT of work, since the footage is about 4 hours long, and there are really, really a lot of fades. To be honest I can not get why Vegas behaves this way. It seems to add the color levels. Is there any other way? Argh, sometimes I hate Vegas. Finally happy that my MPEG2 outputs looks good on most HDTV’s, next problem :'(

I don’t know what will happen when I apply the corrections to seperate clips and then crossfade them in one track. It seems to happen with two of five camera’s more noticable then with others. But all in all when the blacklevel is raised (due to brightness, color correction, whatever) that a grey “film” is generated during the crossfade.

Yeah, the Mpeg2 codec sucks, and not little. I have found that when rendering VBR single pass, it also skips frames in build 726. When I put it in CBR or VBR 2-pass, it renders fine. At least, it renders all the frames. 2-pass is definitely better quality, but hey, you can not compare 576i with 720p.

Is there a (free?) and better MPEG2 codec? I have the idea that Mainconcept is the only provider.

Hi Stephen, all who is reading,

Just installed Vegas 12 (build 367) on a laptop. Exactly the same thing as on my own system. This is probably really something from Vegas. Just saw that there is an update (editing system not connected to internet, laptop is :)). Going to see if that helps.

[edit]
Just updated the laptop to 12.0.726. The problem is changed. Now when I render the same clip (black solid, 0s0f ~ 9s24f), with the default template, I get everything, till 9s21f, then 9s24f. So 9s22f and 9s23f are missing (?). When I change the template to “two pass”, it renders out nicely and complete.

Still this is strange… I anybody has a clue, then please. Because I lost faith a little.

Hi Stephen,

I guess there must be something wrong with my installation then I guess. I will probably have a unique problem… :-/ that is really strange. Since it is a clean install on a fresh Windows.

Going to uninstall and reinstall this evening (European evening, that is ;)). Hopefully that will solve the problem.

Thanks!

I think I have uploaded it… not sure…

Thank for the effort.

That is weird, what can be the problem? For me, it constantly does it, missing the last 10~11 frames.

[Antoine Van de cruyssen]

This really starts to get absurd…

Maybe one of you could simply try this:
New project, insert black solid 10 seconds, insert timecode, and render out in Mpeg2. When I do that, I get 9s12f, when I stretch it to 30 seconds or one minute, it is correct, with 10 seconds it is not. This has nothing to do with loopregion, that is not the problem. Driving me nuts here…

[Antoine Van de cruyssen]

Thank you all for your help! Really appreciate it.

Problem with adding black is that each time it stops “somewhere”, it is never sure, where it stops. Moreover it is strange.

Where can you disable GPU rendering? I found GPU accelerated preview.

Source material is standard AVI, but to be honest, it doesn’t matter what it is (first of all, Vegas should do what I tell it to do). I made a simple example, take a black solid, 10 seconds (250 frames in PAL), put there a timecode counter. Rendering it in .AVI will nicely give 250 frames. Rendering it in Mpeg2 (with the basic template, without sound), it gives 239 frames. At one point on a 4m50s clip it missed the last 11 seconds (273 frame to be precise)

Strangest thing is that if you look at Vegas while rendering, you see that the framecounter, counts till the last frame, also the preview screen shows the last frame (very quickly though). Only the file itself is not correct, which can be easily observed by dragging it into Architect or check it with VLC.

Really getting sick with this, since my deadline is approaching, and I don’t have time to render out a complete film (which is about 13 ~ 15 hours of rendering) 10 times to check it out.

My HW btw is a i7, 2600k running 4.4GHz with 16GB of RAM, GT520 videocard, data comes from one physical drive (E) and renders to another physical drive (D).

Thanks for all your help, really, really appreciate it!

I’m very pleased with my Core i7-2600k, together with P8P67 motherboard from Asus (4x6GB/s SATA, 4x3GB/s SATA, 1x eSATA), and PC1600 memory from Corsair. System idles at 1.6GHz, normal on 3.4, turbomode up to 5GHz but take the “k” CPU. It’s unlocked.
