Clips are black

buffyann · Post by **buffyann** » Fri Nov 23, 2007 4:53 am

Sorry, I didn't know how to name the post better.

I've been vidding in Vegas using AviSynth scripts and VPAvi to trick vegas into reading them. it worked fine, aside from some clip being frozen from time to time (and that got resolved by just restarting Vegas. Probably was the memory leak thing, since I didn't put the setMemoryMax(64) in my scripts...)

But this morning, I opened my project and every single clip on the time line, and all the avi (generated by VPavi) were entirely black. every single one. First time it happens this way. I thought it could be the same thing, so i even restarted my computer just in case, but it just remains this way now...
I've just finished editing the vid and so I'm getting scared that this will not work anymore

it's freaking me out.
I've not done anything new since yesterday where it was working fine. I installed xvid 2 days ago but I don't see how it could be related...

I've opened the avs scripts in VirtualDubMod and they work fine. But the avi created by VPAvi are now black in the player when it wasn't before...
I don't really know what to do.

I asked the question here since I don't know if it's related to AviSynth but it seems to be the more likely ??
I've searched a little bit on the board but couldn't find anything.

Thanks in advance for any help.

a few things that come to mind but not necessarily the problem, some here are much more technical than i am O_o

1) have you changed the speed of your video at all, often speeding up clips will result in them becoming black in vegas.

2) check the properties of your vegas file to make sure the framerate is set to the same as all of your clips, it may have changed by mistake for whatever reason.

those are the two that come to mind immediatly, however i can think of one other thing you can do as a check, to see if your clips are corrupted. this however would be annoying

firstly if you backup both your .veg file, and just pick one of your clips at random to backup as well. recreate the clip from avisynth, make sure to use the same filename and pathway (save it in the same place as the same name) and vegas will detect it as being the original file since it matches what the old one was. if this fixes all subclips corresponding to that clip, you know its a problem with corrupted clips, if not, its probably a problem to do with the settings on how vegas is reading it. however the only 2 checks i could think of to make sure of how it is reading it i posted at the top -_-.

If you havn't changed any of your original clips, or modified framerates/speed or anything along those lines im not sure what the problem would be, and you would probably need to wait for someone else to help.

Not at all. I've rendered the project before closing vegas and changed nothing. and when I opened back today, it was all emssed up.

2) check the properties of your vegas file to make sure the framerate is set to the same as all of your clips, it may have changed by mistake for whatever reason.

Well, that's trickier since i have both PAL and NTSC clips on the timeline so they're not all at the same framerate, but it never was a problem before

however i can think of one other thing you can do as a check, to see if your clips are corrupted.

I'm not sure what you're suggesting to do here. I haven't undertsood everything

But what i did do is try to regenerate the avi with VPavi from the avs script and the resulting file was all black too... which is very odd.

Thanks a lot for trying to help. I'm panicking over here.

does the project preview fine in the vegas preview window and it is only the rendered version which is all black?

No, it's absolutely everything. The clips are black on the timeline, on the preview and the orginal clips are as well if I play them outside of vegas now...
This used to work perfectly. I really don't get it.

just out of curiosity, what codec are the video files?

My guess - You either deleted the codec that decodes the video or downloaded additional ones that are currently in conflict over who should actually handle it.

Thanks everyone. SInce the only thing I did was install Xvid, I uninstalled it and surprise, surprise, it works again...
Since I hadn't close Vegas since I installed it 2 days ago, I didn't correlated the two...

Anyway, thanks a lot for your help and sorry to have bothered with something so "stupid".

I can render safely now
