When rendering MP4 videos with version 25.2, black edges may appear at the edges. MOV and AVI are normal, and when using the third-party plugin Voukoder for rendering, it is also normal

Neither reinstalling the software nor upgrading to a higher version worked. Eventually, I found that the issue could only be resolved if the resolution was set to even numbers. However, due to the particularity of my project, I still used the MOV format and ultimately solved the problem by using a third-party format conversion tool.

Unusual resolution can sometimes cause such issues. Glad to hear that you were able to find a workaround.

Thanks for sharing. Feel free to reach out if there are any other questions. Moving this thread from Bugs to Discussions for troubleshooting.

Modifying the software encoding settings has no effect, nor does launching the software in safe mode. Currently, I plan to reinstall version 25.2. If that still fails to resolve the issue, I intend to install a higher version to address it.

That's not ideal.

What are your system specifications (CPU, GPU, RAM, OS version)? Does it happen with all the project just a specific project? Can you try switching performance from Hardware Encoding to Software Encoding in the Export settings?

Let me know if that brings any change.
