File estimate size before exporting

To see if the video “surpass 100gb”
Really helpful

See Estimated size of the exported file

Though Shotcut could actually start the export in RAM for a few seconds and use the same method as for Estimated size during export to give an estimation:

(…) using the current progress % and the current output size to make an estimation.
So for instance with current progress 5% and 10MB written, 100/5*10=200MB estimated final size.

I totally get why this is a tough feature to implement, especially with VBR. For anyone who needs a hard limit for email or Discord, I’ve found that switching to ‘Average Bitrate’ under the Advanced tab is the only way to get a predictable size. It’s a bit of extra math (Duration x Bitrate), but it’s a lifesaver when you’re trying to hit a specific MB target!
