Webm export estimated file size vs reality

Hi all,

I've a project that requires a webm export.

uhd sequence (58secs)
export settings - webm VP9 1600kbps 8-bit, metadata none

It's saying an extimated file size of 12mb which is roughly what I need for the web application. I'm getting 219mb (tried twice). I can trial and error to reduce the export size but the webm export takes about an hour to spit out my machine. It'll take a few tries to export and it's so timeconsuming considering the overall output size.

Is it possible to make the estimated and actual export size more in line?

PC - Intel(R) Core(TM) i7-6900K CPU @ 3.20GHz 3.20 GHz 64.0 GB RAM

I get a similar projected filesize. Exporting....

The custom arguments box info can be found in the pdf in the folder that downloads for the webm plugin install:

My sample was UHD 56 seconds, exported as VP9 1600 Mbps constant bitrate. Prediction was 11MB; export file was 11.6MB. I have no explanation for the difference you are seeing.

I am using PR 22.3 (the latest update with the new Export workflow). To get familiar settings, I sent the file to AME. But I went back now and looked at the new workflow, and I get the same estimate (as expected).
