Total frames for a progressive scan blu ray keeps doubling. vpy preview total frames shows double of what the output is.

Will look at it later, sounds like a progressive source got Bob deinterlaced.

Quote:Frame doubling
=> all frames should be duplicated,..
first time me seeing this 'in the wild'
(there should also be frame tripling iirc.)
FFMS2 or Bestsource will ignore this and just output 1988 frames.
x264 can create such streams with '--pulldown double' (I doubt this is really 'legal' for Blu-Rays)
--pulldown <string> Use soft pulldown to change frame rate
- none, 22, 32, 64, double, triple, euro (requires cfr input)
I have seen a '--pulldown 32' aka. '(soft) telecine'.
Cu Selur

Bestsource worked! Should have tried that before posting because that's worked in the past but haven't seen this specific problem before. Thanks!
