the converter ignores size limit when using "Change Rate"

this results in a webm with a smaller filesize than desired, with very poor image quality
in the example below, the rate was changed to 150%, with the VP9 encoders

the video in question is too big to upload here directly, so here's a dropbox link to it
and here are the settings used:
You are playing with the limit trying to convert 1 minute long clip in 4MB. Still in investigation the target final size.
Double pass, resize to 720, 1 minute long, 4MB.

Similar issue as OP; I believe I only started encountering this issue since a recent update, wasn't an issue earlier. (sorry can't give you more precise details, just something I encountered earlier and wanted to confirm OP's post)
The last time that feature was touched in 3.18.3. When noticed it?
Apologies, this isn't due to a recent update you made; but I noticed it recently because I recently switched to vp9. It seems to be a vp9 only issue, and seems to only occur with a size limit set in Constant Mode (4mb). No issue with Variable Mode. Are you able to reproduce the issue with vp9 + Constant mode size limit?
Happens with vp8 and vp9. The argument -maxrate:v 519430 keep the quality in op case. I don't have an algorithm for the value tho.
Maybe the new method will not work 100% of the cases but is more reliable now. Check latest update.
Can confirm it seems more reliable with cleaner results now, thank you.
thank you for your work, it seems to work correctly now!
