You were right. Exporting to h264 completed successfully for the same interpolation that crashed before. I'll try exporting to h265 today.
Maybe the AV1 encoder is the issue?
Yeah, definittly something wrong with the encoder. I also need to do some tests with H265. Will try to improve both for the next release.
Reporting back that the H265 export completed successfully too. So most likely the AV1 encoder is the source of the crash.
Cool! Glad this one is working for will. I will see if I can improve both encoders on the next update.
