      I know that a second pass in export gives better compression but my question is as follows:

      Where I work, we do one pass at export. I assume that this is just to save time.
      My question is, does a second pass ONLY help compression or does it give better quality to the final export?

      What do you guys do? 1 or 2 passes?

      Great question. I hope someone know the answer ’cause I’d like to know this one myself. I supposed tests would be the only way to find out.

      think of the first pass as an analytical pass, checking the data to determine bit rates for sections of video, the second pass is the actual render process.

      That’s true but the question still stands… when doing 1 pass… so the render happens on the first pass and the question was if the quality is still the same.

      if you are doing 1 pass, you have to guess at the optimum bit rate, so yes there could be a difference in quality, file size, etc…… 2 pass is a bit more analytical, and could yield you marginally better results overall.
