File size increase about deface HOT 3 OPEN

To save the resulting image it has to be completely re-encoded, so both size changes and a slight drop in image quality can be expected.

The relevant code line for saving anonymization results to new images is here:

imsave() is an alias to imwrite, which is documented at https://imageio.readthedocs.io/en/stable/userapi.html#imageio.imwrite.
Here you see that you can pass image format-specific options through the **kwargs, e.g. for .jpg see here: https://imageio.readthedocs.io/en/stable/format_jpeg-pil.html#parameters-for-saving

For decreasing the output file sizes, I would try lowering the quality setting to something lower than 75.

Can you change the line referenced above to something like

imageio.imwrite(opath, frame, optimize=True, quality=50)

and report if it works?

We can also make this configurable through a command line flag similar to the --ffmpeg-config option, which already exists to control video output codec options.

Sorry, I see I forgot to reply.
For now I decided not to go ahead with this package. Although it would be great to make it more easily configurable, as the file size difference is quite big.

@mdraw maybe a option to run the images through https://github.com/tjko/jpegoptim or http://optipng.sourceforge.net/ would be great.
