Lens Correction Causes Failed Exports

Bug
1

Regardless if I add the lens correction filter to several clips or to the entire video track, Shotcut will fail to export my project. This renders the filter useless for my needs so I’m not sure if this is isolated to my project or if other users are experiencing failed exports when the project includes this filter.

I tried to replicate this bug but could not do it.

Applied the lens correction filter to an entire video track and exported it 3 times with the H.264 high-profile preset, YouTube preset, and WebM VP9 preset. All the exports worked fine.

Then I applied the lens correction filter to just two clips on the timeline and did the same 3 exports. All worked fine.

Sauron,

Would you mind increasing the speed of your clips 2-3x and retesting? It looks like those are the clips causing it to fail for me.

I retested with 2 clips on timeline. One was at 2X and the second at 3X. Applied lens correction to each clip. Used the same 3 exports. All worked.

Then I removed the lens correction from the clips and added it to the video track. Same 3 exports. All worked.

Used defaults for the exports. Don’t know why it’s not working for you.

Thank you for testing. It might be the variable frame rate of all the clips that is impacting this.

Shotcut has a feature to convert variable frame rate clips.

Thanks. I have over 100 files in my playlist so queuing everything up for conversion is crashing the program. Is there another recommended free batch converter program for windows?

Also, could there be an issue with having multiple resolutions of all clips? Here is a sample:

I use Handbrake for batch conversion.

11

Other than changing the frame rate using handbrake, do you recommend any other configurations without changing the quality of the raw file?

Just tried an export with 3 different resolution clips at 2X 3X and 2X speeds and the export worked. I have no idea why it works here.
