Hi Gunther,

I am running LRT6 Apple Silicon version on M1MAX MacBook Pro. When export internally, always missing several jpg files in export folder, those frames are also missed in the rendered video.

By the way, LRT6 is really fast, thanks for your hard work.

Which beta did you use for this test? Could you please try with the Beta 11 that I released today?

I've tried 3 different versions include V11, all the same. About 1-2% jpg files were lost, I tried 4 or 8 parallel sub processes for internal export.

Could you send me the log after that happens? (info menu)

Log file sent. It looks like data in intermediate file error.

Didn't get the log file, did you send it to support@lrtimelapse.com ? You can also paste it here.
