40-sec clip: Vegas renders to 11MB - Microsoft "Video Editor" to 1.8 M

I'm running Win10 with Vegas Pro 12.

My Vegas Pro Timeline:

  • 5-sec intro with (Legacy) Text 44, Sony Color Gradient 45, & voice track
  • 30-sec content has Sony Titles & Text "drop split" with voice track
  • 5-sec tag has (Legacy) Text 44, Sony Color Gradient 45, & no voice track
  • Rendered as Sony AVC/MVC Internet 1280x720-30p
  • Rendered file size = 11 MB

Using built in Win10 "Video Editor" (set to render as high quality 1080p) a similar 40-sec file rendered to 1.8 MB.

  1. What can be the difference in the tremendous file size difference?
  2. How can I render using Vegas Pro to a smaller file size that I can attach to an email and/or put on a clients website to be viewed by visitors.
  3. Been a very long time since I've done this but maybe the Sony AVC/MVC mp4 is rendering as raw... could this be right?
  4. Which "stock" render as choice should I use for posting on the internet or emailing as a attachment?

Thanks for any help.

If file size is paramount importance, change the bit rate target in the render template to meet your expectations.

Here is a bit rate calculator to help you.

Bit Rate x Time = File Size

When you reach your goal, you may or may not be happy with the result from either renderer.

I wonder what Bit Rate Win10 is using when their built in Video Editor renders to High Quality 1080p? Is there a tool to examine the mp4 file Win10 rendered and extract the specs?
Thanks for the help.

Thanks j-v. I remembered MediaInfo on the way home from work and da-da...it was already on my home PC. Been so long since I did video I had to download the new version.

Windows 10 also can display the bit rate of a file from File Explorer by selecting Details View.

The windows photo video editor may encode based on constant quality rather than a set bitrate. I noticed a 1080p video with very little motion encoded at 3mbit/s while 2 others with higher motion encoded at 6 and 12mbit/s. Vegas is not able to do that without addons

OBS also use this way to compress data. Some day I had to record long sessions (~2 hours x 9) of 'tutorial' how to use a machine, so there was some more intense moments, and totally stable. File size vary from 500mb(!) to 5GB at this same settings and time.

Similar? No such thing exists in the encoding jungle.

That said, the same encoder (WMV) is available in Vegas, although I'm pretty sure the presets are different. Its 1080p is actually 1440x1080 anamorphic. Blechh! (that's a techical term).

Still waiting for those file properties so we can show you what causes such low bitrates (yours is 3.5 Mbps).
