Comments.Text: OK, the output is 256kbps / 44.1K. But what are the sample rate and bit rate for the original file?

Comments.Text: My guess would be that the original file was not recorded at 256kbps, but something lower like 192 or maybe even 128.

Title: Rendered mp3 file is much larger than original

  (Asked by: username_0 on 2015-05-13)
  
  In Sony Vegas Pro 10 I've placed an `.mp3` file (about **3MB** file size), then I've cut it slightly at the end to **shorten the length**. I've tried to encode it with following settings:
  
  ```
  File - Render As  
  Save As Type: MP3 Audio  
  Template: Default Template  
  Description: Audio: 256 Kbps, 44,100 Hz, 16 Bit, Stereo, MP3
  
  ```
  
  The encoded file is about **6MB** and it seems that the resulting file is the same quality as original.
  
  How can I render `.mp3` without getting a larger file size than the original?
