Failed to export "Application provided invalid, non monotonically increasing dts to muxer in stream 0"

[HDSQ.mid]

Not sure what’s going on with this… Any help would be appreciated. It exports the first few minutes just fine and then fails around the 3:30 mark. When I tried to export a part of it by importing the MLT as a clip and starting the render at a point a few seconds before the crash, it only got a second or further before crashing. I’ve attached the log of the trimmed reattempt.

Project file: unify final pfa compiled - manual edit 2 - Repaired.mlt (45.0 KB)

I’m exporting using QSV in 4K60 at 70% quality.

Seriously though, any ideas would be greatly appreciated. I’m hoping to get this rendered soon, and the sooner I get it to work the sooner I can be done.

Maybe this is a hint. Have you tried to export without hardware encoding? Uncheck the hardware encoding and try again to see if it works better.

If you find that it always crashes at the same time in the project, I would suggest:

1. Make a copy of your project
2. Open the copy and delete features that you may be using (filters, transitions, clips on a timeline) at or around the time that the failure is occurring
3. If you find a particular feature is causing the failure, then open your original project and remove just that one feature or recreate it.

[HDSQ.mid]

The export still seems to be failing but I can’t be sure why, since Shotcut is closed when I check my PC again.

[Elusien]

What is happenin g in your video timeline at frame 2471? (type “2471” into the time box in the source player). If e.g you have a filter starting there disable it and see if the export now works. If it does, delete the filter and re-apply it, then try to export again.

MAKE A COPY OF YOUR .mlt FILE BEFORE TRYING THINGS OUT, JUST IN CASE.

[HDSQ.mid]

Sorry I’m late. Frame 2471 is a solid 2 and a half minutes before the render fails, and there’s nothing consequential there. I’d say that this is probably a memory allocation error caused by my system running out of resources.

How to Reduce Memory Usage

Here are ways to reduce the memory usage in general: Save and restart Shotcut Close other browser tabs. Close other applications. Reboot (does all of the above). Here are ways to reduce the memory usage of your project: Reduce the resolution of the Video Mode. Reduce the number of tracks. The number of tracks will increase the amount of caching to prevent files from being closed and reopened repeatedly from one frame to the next. Here are some ways to reduce the memory usage while editing: …
