Eyesis is another product frome Elphel where the software to split a
quicktime mov into single jpegs is used. Andrey recommended to use the
software not the product.

This has nothing to do with the camera, it's a general problem with file
handling that performance suffers if you have a big number if files in a
single directory.

I would recommend to go the quicktime mov route as it is the most
sophisticated path.

You already got good replies regarding the same topic in this post:

Elphel does not provide support for non-Linux operating systems.
