I’m having an issue with exporting a project I’m working on. It includes an 1080i video source that has 60 fps when doubled. When exporting, I made sure to pick either YADIF or BWDIF as the deinterlacer. However after encoding, the video still looks like it’s stuck at 30fps, despite what MediaInfo says.
I think I might’ve not portrayed my issue properly. This is not about playing the video real-time at 60fps, this is about what’s exported. The video is deinterlaced, but it’s not doubled, only the elements added in to shotcut play at 60fps high motion, the rest is playing at standard (?) motion.
So I take it that it’s not possible to have the video deinterlaced/convert each field to a frame at the export step? It’s only possible if that was already done to the video?
Correct. We have a batch conversion feature so you can select all your interlaced clips and perform a batch conversion to perform interlace conversion from 60 fields per second to 60 frames per second. Yes, the files will be bigger than you original files.
It is how it is currently designed and nobody has volunteered to make it different. Making it work the way you want would require some changes to the underlying MLT framework.
It is getting harder to get people interested in features for interlaced video since progressive is the way of the future. Volunteer developers are more interested in adding features for modern capabilities.
