Quick question on Deinterlacing 30P in 60i containers

[ayim]

Hey, I had been assuming this camcorder records 60i on everything and just sets some meta-data to say it should be 30P or something, but I just now found it it's actually recording 30 full progressive frames, then somehow converting them to 60i in the camcorder.

So this is the quick question:

Since it recorded 30 full progressive frames, and made them into 60i, would it not matter what deinterlacer I use to make it 30P again? Aka could I just use my NLE's deinterlace to achieve maximum quality since it was already 30P to begin with it doesn't need to rebuild anything? (I can just drop the 30P in 60i files into Vegas and it shows up deinterlaced)

Camera is HF-S100

and here's a quick reference post:

The 24p and 30p modes are real, however, like ALL film, 2-3 pulldown is added to 24p so it can become 60i video. It matters nothing that 30p is stored in 60i format on the SD card. What matters is that the camera captures all the lines of resolution every 30th of a second in 30p. When you import your footage into your editing software, the image data is the same, and there is no loss of quality. The Digic III processor is a marvel, and is able to perform real-time 2-3 pulldown at extremely high bitrate, which is precisely what the HF200 brings to the table over the HF100. Once you set your software to remove the pulldown, you have the 24p footage intact. I shoot exclusively in 30p since then I don't have to bother with 2-3 pulldown removal or de-interlacing, or anything complicated. I just get silky-smooth full resolution video that is already in a format that compliments PC playback, HDTV and LCD playback.

canon 30p in a 60i container is 30p. the file header just says it's 30i(60i is a marketing gimmick term). all you need to do is tell your editing software the file is 30p.

Yep. Don't wreck it by throwing a deinterlacer at it.

When I playback in a video viewer on my computer it shows interlaced lines, so it's actually 30P but says its 60i so the players play back interlaced, but as long as I tell my editor it's really 30P it'll be all ok? So confusing lol and thanks aedipuss and manono for helpin me understand

try playing back with mpc. pause and then frame step through a scene with motion. there should be no interlacing lines. there can't be if it was actually recorded progressive.

in vegas editor you right click on a source file and click properties and change it from 30i to 30p. in premeire pro basically the same but "intrepret footage as" is where you change it.

Yeah, that's pretty screwy since you told us it's 30p. Do you have a small 10 second sample you can upload for us to have a look?
