Artifacts with high threshold in Virtualdub
Posted: Fri Aug 15, 2014 8:19 pm
I have a VHS capture with some letterboxing at various places. I find an increased temporal threshold very useful with VHS (more-so than just increasing the radius) but I have found it leads to artifacts just underneath the upper black border. The artifacts shift from frame to frame and are quite obvious. I have tried a real profile and the default flat profile, both exhibit this problem. I don't believe the profile is the issue.
Closeup :

Temporal radius : 2
Temporal threshold : 150%
Spatial filtering : OFF
Virtualdub 1.10.4
NV3.5
The recording is of a digital satellite broadcast.
Unprocessed and processed clips (HuffYUV):

Apart from cropping the image (the letterboxing is not constant throughout the capture), is there any workaround for this, and can it be rectified in 3.6 please ?
E2A : Filtering is set to "interlaced".
Many thanks.
