OpenShot
OpenShot (Win64) repeatably crashes mid-render (16X Time Remapping)
Describe the bug: During the rendering process, the application exits with an unhandled exception while around 15% complete (possibly at a transition between source files). Rendering on a slow machine, so I've never been at my PC when the exception happens.
Steps to reproduce the behavior: Clean install of daily build Load recently created project Start export/render Render appears to be proceeding normally (works normally for at least an hour) Application exits prior to completion of the export/render.
Expected behavior: I would expect the render to finish without errors.
System Details:
- OpenShot Version: 3.0.0 daily build Win64 (OpenShot-v3.0.0-daily-10912-510a7690-b5bbab66-x86_64)
- Operating System / Distro: Windows 10 pro version 22H2

Hello @hikeonpast
- How larege/complex is your project? Just trying to get an idea. File types, files sizes, how many minutes of clips on the timeline?
- How much RAM is in your computer?
- How much available disk space do you have?
- Here is the instructions for a clean installation: https://github.com/OpenShot/openshot-qt/wiki/Clean-Installation-of-OpenShot. Is this what you did?
- Were you running an older version? If yes, which version and did you successfully export this same project.
Thank you!
Hi @Colorjet3
- The project consists of 7 one-hour files, 4k @ 20 FPS. Goal is to assemble into a single file and speed up 16x.
- 16GB. Didn't behave like a memory leak FWIW.
- The drive that the source/desination files are on has 4.5TB free. The SSD that OpenShot is installed to has 106GB free.
- This was a clean install on this machine - have never installed OpenShot previously.
- Nope.
Let me know if I can answer any other questions.
Edit: Corrected the units on one of my drives.
Other info (if helpful) A daily build from a few days prior also crashed in a similar way on my macbook. This was not a bona-fide clean install however. I installed a daily build over the 3.0.0. release. Stack trace follows:

Thank you for all that information @hikeonpast. I am going to ask one of dev team members to look at this.
Since it appears to be crashing during the ResampleMappedAudio process, you might try and adjust the project / export settings, so no audio resampling is required... as a quick experiment. To do this, verify the following values are all the same:
- Source Video's Audio Sample Rate (i.e. 44100, 48000, etc...)
- Export Dialog -> Advanced Tab -> Audio Settings -> Sample Rate (enter the same value used on your source videos)
If you enter the same values, the audio will not need to be resampled, and thus, things might not crash - at least this is what the experiment might demonstrate.
OR if you are feeling more adventurous, you can install the GDB debugger in Windows, and actually "catch" the crash, which will give us much more info on the crash: https://github.com/OpenShot/openshot-qt/wiki/Windows-Debugging-with-GDB
I haven't had a chance to dive into the code, but is it expected that ResampleMappedAudio is called during rendering of a video that is configured as Video Only under the Advanced export settings?
I'll work on setting up GDB when I have a bit more time.
Yes, each file is wrapped in a FrameMapper class, which is designed to normalize all the source files into the same FPS and Audio Sample Rate, to make the final timeline easy to composite/merge together. Thus, if your project FPS and Sample Rate matches the source files, we can skip this step... and perhaps skip the crash as well... Of course, just running OpenShot in the GDB debugger will tell us all we need to know about why things are crashing.
I just noticed that in your stack trace, ZN8openshot4Clip21get_time_mapped_frameESt10shared_ptrINS_5FrameEEx, which is known to have some "crashes" when applying time mapping (i.e. slow down / speed up video). Since you mentioned the 16x speed, and this method was involved in the crash... I now think it's highly likely the issue you are experiencing.
I will add this to our Trello board, and see what I can find out. I'll keep you posted.

Wait... ZN8openshot4Clip21get_time_mapped_frameESt10shared_ptrINS_5FrameEEx? That's probably why OpenShot was constantly crashing whenever I applied the 'Time' function to a video/audio track, which would instantly crash the app with MSVCRT.DLL causing 0xc0000005 (EXCEPTION_ACCESS_VIOLATION). But in my case, everything was stated in #1197, and this was happening in versions before 3.0.0. The only fix was to reset all OpenShot preferences by deleting openshot.settings in the user's .openshot_qt folder, which would cause the app to create a new one with default settings when launched.
Thank you so much for submitting an issue to help improve OpenShot Video Editor. We are sorry about this, but this particular issue has gone unnoticed for quite some time. To help keep the OpenShot GitHub Issue Tracker organized and focused, we must ensure that every issue is correctly labelled and triaged, to get the proper attention.
This issue will be closed, as it meets the following criteria:
- No activity in the past 180 days
- No one is assigned to this issue
We'd like to ask you to help us out and determine whether this issue should be reopened.
- If this issue is reporting a bug, please can you attempt to reproduce on the latest daily build to help us to understand whether the bug still needs our attention.
- If this issue is proposing a new feature, please can you verify whether the feature proposal is still relevant.
Thanks again for your help!
