Issues rendering on Videostudio Ultimate 2021

[alicedonut]

I am trying to edit a 21minute long multi track video and it gets to around 30% (different percentages each time) then it crashes. No warning notifications or freezing the software just closes.
I used the software to edit one track videos around 6-10minutes and they render just fine.
I don't know why it won't work.

Welcome to the forum.

To be able to help, we need more information. First, did the video in the project all come from the same camera? If so, then what are the properties of that video -- right click one of the clips in the timeline and select Properties. If not, then please supply the properties of the various types of video in the project.

Next, what are you wanting to produce in terms of format: something with the same properties as the video in the project, or a different format? What are your project properties?

Have you done anything different to video around the 30% mark -- e.g. applied a filter, changed the speed of the clip in that area, altered the audio? Or does the video around that point have slightly different properties to the rest of the project? For example, is the frame rate variable as opposed to being one of the standard frame rates (25, 30, 50, 60 fps)?

I am trying to edit a 21minute long multi track video and it gets to around 30% (different percentages each time) then it crashes.

Is it crashing during editing or during rendering? I assume during rendering, in which case there is a problematic clip at the percentage where it crashes. You'll have to look at the clips where it's crashing and check for any filters, etc. that are being used. Another way to find the problem is to create a preview range that stops before the problematic area and render that range, if the render is successful then increase the range until the section causing the crashes is identified.

Rendering problems can also arise if your project properties don't match the properties of the clips used in the project.

ok I'm going to try and render part of the video and keep increasing the time rendered to see if I can find a problematic clip. Fingers crossed.

I've gone from 33% before it crashes to 54% and counting... lets hope I've fixed it!

Try gradually. It may a transition and Fx you used. Try a low res render to speed the process. Also my experience says not to use nvidia or AMD acceleration.

Hardware acceleration is a known problem: it works on some systems and not others, generally related to the hardware or relevant drivers. It could be the video processor on the main chip (intel), the driver for it, the display adapter if you have one or the drivers for the adapters. Lots of choice there. Disable the acceleration is the most direct way of isolating it. Example; I have a core i3 Intel cpu, using the on-board display adapter, and hardware acceleration simply does not work in 2 video editors, but accel disabled with software only, both render fine. I tracked it to the Intel driver for the display chipset, which apparently has a bug intel will not fix because at 5years it's too old.

To isolate the issue to just the VS software, disable all acceleration in the preferences setting. A render will take longer in this mode but any issue will be VS. As a rule of thumb, rendering will take at least as long as the video file composition, and probably longer depending on the file format (eg FHD) and what effects etc you have used. So, rendering your 21minute vsp will probably take around 30minutes. A same format render (all clips are the same format as the intended output) and you have smart render on may be the exception.

Smart render has also been known to cause an issue, so try a render with this feature off.

The %age pint where it crashes is directly related to the place in the vsp: if it crashes at 50%, then half way thru you vsp there is something (a filter, effect, maybe a video clip with an odd frame rate or different resolution (Vs will match the 1st clip of the vsp, but not ones you have introduced later in the project file).

If the render by range doesn't lead you to the problem, try disabling some of the tracks, one by one, and render with the selected track disabled. Disable a track by selecting the camera or other icon icon at the extreme left end of the tracks (mouse over label is "disable xxxx track" where xxx is video, overlay etc). If you find that the render works with a track disabled, then the problem is on that track. Combine with the %age fail report and that disabled track at the %age point is the issue.
