Deinterlacing with “none” sequence

[Rafael Amador]

[Michel Domaine] “somebody told me that if I put some interlaced footage in a sequence with “none” field in the settings, Final Cut automatically deinterlace my footage exporting a progressive video.
Is it true? “
No.
FC automatically adds the “Shift-fields” filter when you put interlaced footage on an interlaced sequence with the opposite field-order. So you get that when you drop Upper First footage on a Lower First sequence or the other way. Shift the field order by displacing the picture 1 line up or down.

You are right. You have to set a de-interlacer by your self.
Good deinterlacing is critic for a good quality. Try to avoid the FC default de-interlacer.

What Rafael says, but you really should precisely state your objective before going ahead with any deinterlacing method.

Precisely why is it that you have determined a need to deinterlace?

Thanks Rafael and David,

that was I ever experienced and I ever thought.
Mine was just a curiosity, cause my friend told me “put none” with a lot of security! 🙂
And, actually, I tried some export of prores “none” FD sequence with interlaced material without filters and it looked like he was alright: export was clean on computer screen, without “interlaced artefact”.

Normally I prefered to deinterlace exporting, or export a quick time movie sequence and deinterlace it with compressor, cause I really don’t like “deinterlace” filter in final cut.

Thanks again everybody.

Big mistake, the way to be sure about interlacing issues, is with an interlaced monitor (in fact many people keep them just for this reason), or using an application that lets you step “field by field” (like AfterEffects).
With something like QT Player on a computer, you can’t never be sure.
In FC you must set the Canvas size at 100% and render the picture.

Thanks Raphael!

Fortunately it was just to try, to see if he was right, but for my jobs I ever worked like always and like you confirm to me with your answers.

Thanks everybody.

P.S. I have to learn how to go “field by field” in After Effects. I didn’t know that.
