Answers.Text: This works fine for me with smaller files but it doesn't seem to work for large files (~600GB). Do you have any ideas what could cause this?

Answers.Text: The LossLessCut [website](https://mifi.no/losslesscut/) mentions "Shave gigabytes off video and audio files in seconds" so I guess is rather well suited for handling large file sizes. But maybe the chapter function in particularly is not memory optimized? Try ask at their Github [discussion forum](https://github.com/mifi/lossless-cut/discussions).
