This is a single video, being processed once, with 2000 filters being 
applied? That in itself sounds like a recipe for disaster, and that a more 
purpose-built editing system would do a better job (e.g. openshot or 
shotcut, both are open-source). You may be able to create an EDL (Edit 
Decision List) from your filters to drive the editor software.

If you have storage space, you could also use uncompressed intermediate 
files and successively run smaller groups of filters on them.
