Zoom can record your meeting and render a video of the meeting. These are super compressed files. Zoom is typically headshots and screen shares. Not fast motion. At what bitrate did Zoom render the video conference ? The app renders it at Under 300 bps!!!   With no loss of clarity.  45 mins video is only 70MB.

Here is the weird part. I had to make some edits to the video in Vegas. Cut some stuff out. I render at the same bitrate as the source file (300 bps), I get grainy resolution. No idea why.  I had to re-render at 2,000,000 bps to get the same clarity as the source video which is only at 300 bps. The encoding codec I am using is using Magix AVC/AAC MP4.

My Zoom laptop is 1366x728 so that is the resolution of the Zoom video.   Not changing the screen resolution also makes much faster rendering. I set resolution same as source file 1366x728 and render time was 5 mins. For a 40 min. video. w/ 2,000,000 bps  (File size 600MB)

Bottom line.  To render a video w/ Vegas with the SAME quality as Zoom’s raw output, my filesize needs to be TEN times bigger (60MB vs 600MB) and a bitrate of almost 10x as well. (300bps vs. 2mm bps)

Anyone know what is going on? I'd like to cut down the source file (300 bps, 60MB), and render something similar.
