Technically 60 fields are from different frames, so… depending on deinterlacing it could be between 1/2 and 1/4 of the information. That is why I am so curious about Shotcut’s internal deinterlacer that we have misunderstanding about.
I believe when 1080i is brought into 1080p timeline/mlt some internal de-interlacer is applied prior to any other filter and then material is progressive and Export > Advanced > Video tab > Deinterlacer has no effect. Look at this post
The question is what is that
deinterlace=deinterlace,avdeinterlace
When mlt is progressive=“0”, I believe, based on clearly interlaced Export Frame that I uploaded earlier that included my filters and all, that Export > Advanced > Video tab > Deinterlacer is applied AFTER all filters and before feeding now progressive frame to the encoder.
Do I, may be, explaining the difference more clearly?
In my experience with “my couch noise” there is a big difference between when I have interlaced mlt vs. exactly the same mlt with progressive=“1” in mlt profile.
