Notes:

Using RVD: when using RVD, best results will be obtained by using RVD with Composite input.

SDI Input results with RVD vary.

•

If Video Autofill is on, bitrate will be automatically calculated, and is not editable by the user in that case.

•

The video rate designated on this panel is inclusive of the video payload and 1% (roughly) overhead buffer.

Note that when encoding to file, the file registration system will only report back the video payload rate.

Example: if the video rate is set to 15, the video rate detected for the file will be less than 15. (Ex.
14.60)

I-Frame Only Encoding: at any given bitrate (fixed), video quality will be greatly degraded with I-frame only
encoding. The table below gives a relative idea of the video quality that can be expected with different GOP types.
