Supression of Low Disk Space warning

Post by cNode » Sat Sep 22, 2018 5:32 pm

Description of problem or question:
I have a 1.68Gb free disk space and I am trying to compress a video file of 50Mb, it says I have low disk space and can't continue. Surely 1.68Gb is plenty for a 50Mb video compression, I am guessing the program looks at drive % of total available so the larger the hard drive is, the more space free is required regardless of the size of the video. This is inefficient.

How do I suppress/bypass the warning? Also, I have 16Gb of RAM, why doesn't Handbrake just pre-load the entire project into RAM and run from there before creating the output file, instead of spooling directly to the hard disk/temp directory? It would be faster and more efficient. Thanks!

HandBrake version (e.g., 1.0.0):
1.1.2



Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):
Windows7 Ultimate x64

Low disk space level is definable in preferences -> Advanced

HandBrake already utilises all the Memory it needs. All the processing / buffering is already done in memory. There is no need to stream the entire file into memory. Even slow hard drives are more than fast enough to feed HandBrakes buffers.
I'd also note that all the processing is done on uncompressed video. It's many many times your source file size. (Since it's decoded / uncompressed in memory). A typical bluray would blow up to hundreds of GB of uncompressed data.

Your video uncompressed is over 40GB, so you're ~30GB short on RAM to do what you propose anyway.
