non-deterministic output

[Chen-Cai-OSU]

Hello,
I am uploading the same video to v1.3 and encode it twice (renamed the first video). I then did

shasum -a 256 file1 file2

but the file are different. I wonder why this is the case? I expect two files are exact same.

The reason I am doing is I am using command line instead of UI, and want to make sure two approaches yield same results.
The command line I am using is

"/opt/homebrew/bin/spatial" make \
    --faststart \
    --input="$input_file" \
    --format="sbs" \
    --output="$output_file" \
    --cdist="64" \
    --hfov="180" \
    --hadjust="0" \
    --primary="left" \
    --projection=halfEquirect

Can you confirm this is the right command? Thank you!

Hi @Chen-Cai-OSU. This is not something I have explored in depth.

If you run the spatial command line task twice do you get identical results? The GUI is simply a thin wrapper over the raw CLI commands, nothing more.
