Start Trim not to Keyframe, causing "no video" on output

I thought I would post what I think is another example. I went ahead and uploaded the log files to the mcebuddy server if helpful. Similar to a few others, when processing a Playon Cloud recording with a Cut Start, it does not show a video after processing. Running it a second time without a Cut, and it processes & plays fine. For kicks, I re-ran a Playon file from the desktop version (v4.5) with a Cut Start of 4 seconds and it plays back fine.

Log # 1: is from a Playon Cloud recording, with a Cut Start of 6 seconds. After it processes, no video shows.

Log # 2: This log is from the same source file, but with no cut. It processes & plays back fine

Log # 3: This log is from Playon – desktop version (a few months ago, using v4.5). I set it up with Cut Start of 4 seconds, and it processes and plays back fine.
