Title: Recorded .fr files a little too big
Post by: player987386 on June 19, 2025, 07:46:47 PM

Hi! As always, thank you for FBN!  :smilie:

Been doing some gameplay recordings in .fr using the last nightly build and noticed the recording files are a lot bigger than the ones from my "main" FBN build (circa 2023).

Example:
. old FBN record, around 30kb
. last nighty build, around 2400kb

Is it expected? Is there some recording system changes during this time? Not a problem though the recordings work perfectly, just a matter of  curiosity.

Hi,
The main difference is, I removed the compression from the input recordings and state (incl. nvram).

There's a few benefits to this, for example:
makes it easier for external tools to edit the data, for speedrun-stuff
it's much faster without the compression
It's also more reliable, as zlib likes to overinflate if the data changes in the most tiny amount.

best regards,
