  Posted by Andrew Taylor on June 13, 2019 at 12:01 pm

  Hi

  I created a webcam video of in mp4 format from a logitec camera
  I took it into vegas in mp4 format and trimmed it
  (there does not seem to be an uncompressed file available)

  But when i produce movie in vegas, the quality is very poor
  How can i improve the quality?

  thanks
  Andrew

  Hi Andrew! I thought your issue sounded familiar:

  So, nothing changed?

  I captured a widescreen mp4 from my webcam at 17k bps.
  So do i need to set vegas at the same 17k bps?
  There does not seem to be an option to select bps in production in vegas.

  Just so i undertand, it’s ok to import trim then export an MP4?
  (not that i have a choice because webcam creates an mp4 to start with)
