I don't know about you guys, but most of the stuff that takes up space on my drives are:
1) Videos from my DSLR
2) RAW images from my DSLR
3) Various movies / TV series I downloaded
4) Game files (most of which are textures and 3D models)
None of that stuff is really compressible.
- jandrese 6y agoThe RAWs aren't compressible? Are they LZ encoded on the camera?
- kortex 6y agoRAW imagery I have worked with is about 25-50% losslessly compressible on average. Most of your gains in image compression are from quantizing the gamut in clever, (usually) imperceptible ways. Raw imagery contains a lot of entropy that usually doesn't affect the appearance perceptually, but still has sig figs that frustrate compression.
- bufferoverflow 6y agoI just tried compressing one with 7-zip ultra level compression. Saved maybe 5%. Wouldn't get even that with realtime compression.
