I use Avidemux 2.5.6. I need to do some alteration to the source video which is not listed in the current filters. It's likely possible by Avisynth Stab filter. But I'm not familiar with this software. So, please let me know:
1. Is there essentially possibility to add custom filters to what is currently listed in Avidemux?
2. If so, is there such a filter?
If the answer be negative, I've to learn how to use Avisynth and how to activate and work with its Stab plugin.
