Hi Helpful persons.
I have a number of video files. Most were sourced from Youtube originally. Zipping them does not reduce them. I thought if I tried using handbrake to compress them it might save room on my disk. "Compressing" and selecting much lower than a placebo quality still results in about a 4 times increase in file size.
I imagine that these videos were all very compressed when they were uploaded - and that this is pretty common. IOW it is impossible to further compress them. Is that true? Are there any tips to get them to compress a bit more? Is there any way to guestimate what will slightly increase their compression, without having to run a dozen tests on each one?
Steps to reproduce the problem (If Applicable):
HandBrake version (e.g., 1.0.0):
Most recent available as of yesterday.
Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):
Windows 10 Spring Creator update
