My first question is: while using the same build of BD-Rebuilder (0.62.16) on different PCs why do I get partially differing logs? For example, I get Source Video details (codec, rate/length, bitrate) on Windows 10, but not on Windows 11. Is this normal?

The second and most important question is: if I select two-pass encoding on Windows 10, I get two-pass encoding (see the log - it's clearly written there - Pass 1 of 2, Pass 2 of 2. But on Windows 11, no indication of passes, just re-encoding video... If you just look at the log, you may think it was a single pass process. But I decided to watch the process closely and noticed, that when the first pass was over, BD-rebuilder started to process the video again, without informing me about the second pass. It looked like the first and only pass consisted of two parts. Was it really the 2-pass processing? Does anybody know why this strange behavior takеs place?

P.S. Update: My mistake, LAVFilters were not installed. However, the BD-Rebuilder worked wihout them. Now everything is in place.
