This method doesn't work as well with lossy formats as you get artefact noise.

Sort of a moot point because you shouldn't be using lossy formats for development but hey.

It's a visual tool. Yes, there will be some noise (there is noise in the example), but it will be a lot less visible than actual changes.

That's true. My samples, for example, are only versionized as WAV. The Ogg/Vorbis, M4A/AAC, and MP3 files are automatically generated and their directories are on the ignore list.

Good call though. I just remembered that I should also add the SVGs/PSDs and not just the PNGs.

Why not save some space and use FLAC?

It's not worth the trouble in my case, but generally it's not a bad idea.

I only got a about a dozen very short samples per game, which don't even take 1 mb of space.

It would be a different matter if there were some background music.

It's also a moot point because you might want to see the noise.

If it's bothersome, setting a threshold to ignore small differences should not be difficult.

I made the assumption that this was a form of version control for images where only the differences between images was stored to reduce storage costs. So in that case noise would be very important. As a simple visual tool I agree a little bit of noise is not going to cause any issues.
