  Why is Vegas doubling file size when rendering?

  Posted by Maria Maronska on November 12, 2015 at 9:33 pm

  The original file was recorded using the following settings:
  

  Then it was rendered in Vegas (without any changes, just for testing) with output settings:
  Audio: 48 000 Hz; 16 Bit (MAC); Stereo; PCM
  Video: 25 fps; 1280×720 Progressive
  Pixel Aspect Ratio: 1,000

  The original AVI file size is 369 MB and the Vegas rendered file is 753 MB. Why the difference and how to make the rendered file smaller without losing original quality?

  You didn’t say what codec or bit rate you used for the render but only thing that will change the file size is the bit rate. Increasing the bit rate increases the file size for a given codec.

  But you haven’t mentioned what codec you rendered the final output in!
  The codec is the single most important issue where rendering to a smaller
  file size without much quality loss is concerned.
