Really weird Detelecine problems on 60 fps source file
Posted: Wed Apr 03, 2019 4:36 pm
Description of problem or question:
I'm trying to encode a 60 fps broadcast recording (In this case, Fox, which uses 720p60). The source material, The Orville, is shot at 23.976. I've used handbrake before with detelecine, and it can handle properly reducing 60 fps to 23.976. I just enable detecine-default, and leave decomb disabled, while forcing frame rate to 23.976 (since it's a progressive source; enabling decomb didn't fix this problem anyway). However, I've been seeing a really weird detelecine problem recently, including with other shows, but The Orville gave me a prime example to show others what's happening.
I clipped out the opening segment of the episode: A live-action cold open, then the opening credits using effects. When I set the frame rate to 23.976 and set detelecine to default, the live-action cold open looks perfect. But there are weird frame issues in the opening credits. If I set detelecine to off, it's exactly the opposite: the cold open has the weird frame issues... but the opening credits look perfect. The transition happens at 1:44 in the video. It's not limited to the opening credits: The problem will typically reappear at some point later in the episode. In other episodes, it happens from the very start.
