Att:- Atak (MDegrain custom filter testing)
Is there a way to confirm that these "Custom" MDegrain filters are / or have been used ??
Other than creating some short test encodes and comparing the fps, kbps (whilst processing), or time taken to encode & final file size ??
Anyway, I did that, and here's some interesting results:-
a test tv episode, mp4, 17 minutes long.
MDegrain1 took 8:34m
MDegrain2 took 11:43m
MDegrain3 took 15:18m
they are ALL with MT enabled.
Then I ran MDegrain1 test again changing the MT settings.
with no MT, it took a "massive" 28:25m.
with MT enable, but using 16 threads took the original 8:34m
with 8 threads it took 8:17m
with 0 (which must be unlimited) it took 8:08m (on my 24 thread pc)
so going on that all the above times would be a touch faster if I had of had it set on 0 threads.
As for file size change:-
original file is 255,856kb @ 1,923kb/s
MD1 encoded is 303,196kb @ 2,192kb/s
MD2 encoded is 289,490kb @ 2,126kb/s
MD3 encoded is 281,275kb @ 2,126kb/s
No other filters or changes where made, using CRF 20, and ONLY the custom MDegrain filters.
