Need help with companion files

[snowfl]

Got two questions.

1. Master files always have this suffix "_s" and companion files are video files

example

Filename_s.jpg Filename.mkv



2. Master files are videos and companion files are saved frames from the video

example

Filename.mkv Filename.1653.xnf Filename.2323.xnf Filename.3434.xnf


I tried lots of combination on association list and none of them are working.

How do i accomplish these two?

Thanks

not possible, filename should match

2. Master files are videos and companion files are saved frames from the video

I can reproduce - {ext} does not work as expected

• case 1

  master	companion
  *	{ext}.abcd
  jpg	{ext}.abcd

  a.jpg
  a.111.abcd

• case 2

  master	companion
  *	{ext}.{ext}.xxx
  jpg	{ext}.{ext}.xxx

  a.jpg
  a.111.222.xxx
