It stalls immediately with "Calculating remaining time". Spends several minutes with no number then when the number finally does appear it is very high (lowest I've seen is 85+ hours) and constantly increasing and never producing any output.
Did some more testing and I have a place for you to start looking for the problem. Since my reason for installing this beta release was because it fixes my cc problem, my initial testing was with recordings that had the problem. When I tested today with recordings that did not have the problem, it appears to work fine.
There seems to be an issue with the caption fix we just added and down sampling the video resolution. We're looking in to it. If you bump the resolution back up to 1920x1080 it works fine. Like I said we're trying to figure out why the resolution change is causing an issue.
I uploaded 4 files. The profile xml, the source sample and two output samples. First output sample was created directly from the original source while sample2 was created from the source sample. Uploaded to folder TZG-35946-339.
