16bit .tif FFMPEG aspect ratio problem aborts movie export

Offline
#1 pemo
When attempting to use the ffmpeg movie encoder on 16 bit .tif sequences (exported by LRT) at source resolution (in this case 6720 x 4480 - shots from a Canon 5D MkIV), the export process is aborted due to a bug that reports the aspect ratio as "infinite";

Here's the relevant export log extract:

[size=x-small][font=Helvetica Neue][size=small]Presumably a division by 0 is occurring somewhere?
