"No such file or directory" when recording with roundtrip

[olibclarke@…]

The following bug report has been submitted:
Platform:        Darwin-18.6.0-x86_64-i386-64bit
ChimeraX Version: 0.91 (2019-06-07)
Description
I get the attached error when attempting to encode a movie with "roundtrip true". The command used was:

movie record supersample 4; perframe "hue_up protein" frames 30;  wait 30; movie stop; movie encode roundtrip true

where "hue_up" is an alias defined thusly:
alias hue_up color modify $1 hue + 5

The same command without roundtrip true correctly records the movie.

Cheers
Oli

Fixed.

Looks like movie encoding thought there was one more recorded frame than there actually was. Not sure when that bug crept in.
