Duplicate frames issue

[tupper]

Hello, I am trying to encode Lady Audley's Secret (DVD) using x264, muxed into an mkv. I am noticing strange patterns of duplicate frames in the encode. Judging by the Wikipedia article (https://en.wikipedia.org/wiki/Lady_Audley%27s_Secret#Adaptations), it was shot on UK TV standards and then adapted for PBS in America.

I am new to the weird world of telecining and such. Attached is a 30 second sample of the film featuring a motion shot where many duplicate frames can be found. I have also attached the log from Handbrake. The DVD is encoded at 29.97 frames, but I seriously doubt the source comes at that rate. When I encode it at 25fps I still get duplicates.


Any help would be appreciated. Cheers!

I need to see a sample of the source to be sure. But it looks like you have a field blended PAL to NTSC conversion. Handbrake will not be able to fix that, you'll need AviSynth. The filter sequence will likely be:

QTGMC()
SRestore(frate=25)
