Error compiling movie. Unknown error.

Not really sure what specific forum this falls under, since it varies so I'll just go with where I think it belongs...

I'm working on a video in Premiere Pro 2.0, and all's well with it until I add a particular .avs file and the shit hits the fan.

"Error compiling movie. Unknown error."

However, the solution isn't as simple as one might think. Both my hard drives are NTFS, and I have 70gb free so I'm presuming it's not an issue with space or that my drives are FAT32.

So, I'll fill you in on the details in the hopes that someone will know what is going on...

I used the screen capture program "Webinaria" to record a short sequence of the music waves in WMP. The capture was at 15fps and produced an uncompressed .avi file.

I then used an avisynth script to crop the video into the amount of information I needed:

AVISource("E:\maps_video\Recording.avi")
Crop(0,65,-20,-135)
ConvertToYV12()

Which produced the video I was looking for. However, the video had multiple vertical lines running throughout it, suggesting something was wrong (pic related).

Since the original .avi file didn't have these lines, I decided to re-encode the .avi under a new codec. I rendered it with a lossless lagarith codec, then I converted it once again into a h264 .mp4. After that, I once again turned it into a .avs file using ffmpegsource.

Now, I've taken this into Premiere once again and tried to preview render it, but it still gives me the "Error compiling movie. Unknown error."

I've tried different preview compressors (picvid and midivid) but to no avail.

I know this problem isn't occurring because of anything else on my timeline (.png files and .avi) because they render fine without the aforementioned video.

I've asked around to an extent, and nobody so far has been able to fix it. I come to you as a last resort, but if all else fails I'll probably not use the waveform at all, which is something I'd rather avoid.

Why using an avs for a h264 file if you already have the lagarith version? Lagarith works really fine in PPro 2.0.

Yeah I know. I already tried importing the lag into Prem with the same results, it didn't render properly, which is why I tried encoding it to h264.

I'm presuming it's coming from a corrupt video file? Which is why I don't get why it can play perfectly fine, it can even encode properly but it refuses to preview render?

I have seen something like this before - and it happened while I was working with an uncompressed file too. On that occasion I was getting what looked like a regular "off by 1" error in the colour space, which created a regular artefact not unlike the one in your pic. So I am wondering if your conversion to YV12 might be involved in your case - possibly when combined with the crop.

I suggest you go back to your original uncompressed AVI and open it in VirtualDubMod, and convert it to lagarith, with no filters applied.

If that works, you should then have a stable base for your AVS script.

I tried this just now, and I thought it would work, but as usual, the render started slowing down in the final 80% and gave me the error message again...

So, I took the original .avi file into VDub, converted it into a lag. Then I used the avisynth script

Code: Select all

AVISource("E:\maps_video\recording_lag.avi")
Crop(0,65,-20,-135)

to see if it would work. It didn't.

I added the

Code: Select all

ConvertToYV12()

But still no change.

I honestly don't get what the hell's going on with this...

The problem, imho, is in the original record. I'd try re-recording WMP's wave and if it still doesn't work, maybe trying with another screen-recording program (CamStudio is a good one). If that still doesn't fix it, then I'm clueless.
