I've also had so4compoundplug.dll cause this problem, though for me it would freeze closer to the 18-20% mark. Try disabling that and rendering it again (there is a sticky thread with instructions on how to disable it on this forum). Also, if using NVENC, update your GPU drivers.

So, I am using Sony Vegas 15, and I am not particularly happy right now. I've spent many hours working on a project, and have just finished it last night. But, when I go to render it, it always starts, and then stops abruptly at 88%. Always 88%. Then, when I try to cancel, Vegas crashes. The only way I can close out of it is through Task Manager. I've tried removing the clip there in case it was corrupt and/or causing a problem, but it still does it.

I've also turned off GPU acceleration, as I read that that may be a cause, but that didn't work either. I do not want to loose all my work, so if anybody has a solution, that'd be great.

I recently stumbled upon a similar problem and found (kind of) a solution to it (not sure if it's your case though). I'm using Vegas Pro 15 build 261 Steam Edition. I also had a rendering dead-freeze, and tried different render presets, formats, switching the GPU support on and off etc. Didn't help. What helped was switching Deinterlace Method in Project Properties from "Smart adaptive (GPU Only)" to "Blend Fields". Apparently, deinterlacing rendering some old SD mpeg2 files while sharpening, color correcting and upscaling to FHD using "Smart Adaptive (GPU Only)" lead to a freeze. Hope this helps.

Also, please check which frame it freezes rendering on, if it's the same spot every time. Mine was always that old SD mpeg2 footage bit (while other footage was of different formats). If you figure out which footage causes the freeze, try to compare it's properties with other footage in the project (if it's different) and find the difference. Maybe this way you might come up with some workaround like I did.

Are you using any audio VST audio plugins on any of your clips?

I had a project recently that played perfectly all the way through in real time but locked up every time I tried to render. Traced it back to a VST plugin. Don't know why it works in real time but not rendering, but that was the cause.

I'm not sure if this is the same problem, but I encountered something similar to this issue whenever I was rendering a 41 minute project. 3 to 4 hours in the rendering process, VEGAS Pro 13 Edit would glitch up at a specific spot. It turned out that I had put too many text events at once, so I moved all the text into one event. This cost me the ability to make the different text in different colors, but the video successfully rendered afterwards. This is most likely a problem with the consistency of the processing level, as a 3-minute RPG background I made with over 50 video tracks used at once successfully rendered after around 3 hours. In contrast, my 41 minute project had an average of 4 tracks at once, and the problematic spot (before reducing the number of tracks used) had upwards of 15 tracks at once.

Hey guys!

I just wanted to thank you all for your responses. It ended up NOT being the clip that it was frozen on, but the clip 2 SPACES ahead of it! I don't understand why it was doing that, but I took it out, and it rendered normally.

I didn't just want to leave y'all here without responding. But, thanks for everyone's time and input! I greatly appreciate it! (And honestly, I feel so stupid right now.)

Thank you.

Glad we could help.

I have the same problem like Jeff. If I insert any plugins it just freezes on rendering. Any help?

Please give helper a Chance and describe YOUR environment - start at "B"

Same procedere as every time .....

There could be 3 causes:

(1) Your computer may be rendering it very slowly. My computer has 16 GB of RAM, and some of my most "edit-heavy" sections render at a speed of around 3 frames per second (Project Settings: 4K 60FPS). If your computer has less RAM, then it will probably render slower than this (especially if you have the same project settings as I do). If this is the case, all you need to do is wait. If your project is rendered by at least 1 new frame from the point of freezing, then it's likely that VEGAS Pro hasn't froze, but is rendering the project very slowly.

(2) If your project is light on editing before the picture with plugins appears, then your project might freeze due to a sudden shift between "edit-light" and "edit-heavy". I've experienced this when I was rendering "Secretsoft Dan's Classic Windows Errors (Episode 19)". When the video reached the point where I put an advanced Color Changing plugin on a Test Screen, it would freeze every time, likely because there was nothing being displayed for around 20% of the project (this section was sound-only). So I removed my 3D Watermark (Media Generator: NewBlue Titler Pro 5) for the duration of the screen, and it successfully rendered (albeit slowly).

(3) There is this certain transition (Split → Squeeze, In, Center) that messes up my project's rendering no matter what. In the case that one or more specific plugins messes up the rendering process, you will need to use a different plugin. A useful "edit-light" color-changing plugin would be "Color Corrector (Secondary)", with its various changeable options.

i7-8700k, 16 GB DDR4, GTX 1070 - Enough power for rendering and before this I had ryzen and the same problem occured there.

Sony Vega pro 14 build 270.

Windows 10 pro - 1709

Exact symptom is: whenever I add a plugin for example VEGAS Spherelize it just renders for example to 27% and stops. It won't render it.

@Divisor

Strange... Sphereize usually works for me (although I haven't used it since I switched from VEGAS Pro 13 Edit to VEGAS Pro 15 Suite)...

Try replacing it with the near-identical Pinch/Punch.

One thing that worked for me was that I went to options/preferences/video and set "Dynamic RAM preview max (MB) to zero. After that it rendered normally.
