Freezes when moshing a large file

[bejucoo]

Hello, I'm trying to mosh a large .mp4 file (h264 encoding | 1hr long | 3.5Gb) but the script freezes at 32% every time I try. It detects scene changes perfectly but the problem appears at the Writing moshable file stage:

[1/3] Writing moshable file... 32% [===> ] [5m31s:11m44s]

The log file is attached if you want to take a look. Any ideas of what's going on?

I was able to pass the Writing moshable file with a 17min and 430Mb video but then an error ocurred: Error: error moshing AVI file: bufio.Scanner: token too long. With a 10min and 200Mb video this error ocurred: Error: error writing output file: error parsing output time value: strconv.ParseInt: parsing "": invalid syntax.

I'm seeing the same error message:
Error: error moshing AVI file: bufio.Scanner: token too long

Since it seemingly only happens with larger videos, I did an experiment and rendered out the same video several times at different bitrates. Interestingly when the video is larger than 65MB, then the error message above happens.

Just to confirm, I then used a different source video and rendered it out at different bitrates. The 65MB limit still held true and doesn't seem related to the bitrate, but instead the total file size.
