Estimate File Size?

Hi
Is there a way to see an estimated file size for the project you are about to export in DaVinci?

There is not.

It will always exactly be bitrate x duration.

Avid has a chart of all the DNxHR bitrates

With H.264/265 you are manually entering a bitrate in the constant bitrate field.


Resolve's constant quality VBR option is undocumented and I never see anyone using it. The Good/Best VBR option is junk in general and you don't want to use it.


If you do need a good image quality file at minimum size, you will need to export dnxhr and re-encode with a tool like handbrake. This constant quality mode will adapt bitrate to the exact movement of the clip, so you will not know exact bitrate until complete. but you can (and should) certainly run a sample file before doing a 2 hr project.

Thanks

A made a very basic fusion generator that estimates the size a while ago.
You can try it to see if it works for you
