Changing 24f to 24p possible now?

Hi there

There are reports that it is now possible to change the 24f footage shot on the Canon to 24p. Is this done in post? In the camera? Anyone can enlighten?

24F basically IS 24P. The image recorded to tape is definitely progressive. Canon is only using the "F" moniker because the camera uses interlaced CCDs to acquire a progressive image.

hmm, according to the company where I will doing my HD to Film transfer, 24F is NOT EXACTLY the same as 24P. Which is why this is important to make the distinction.

24F is ingested into an NLE as 24P. For example, with Final Cut Pro, you use the 1080 HDV 24P capture settings to get 24F into the computer. As far as Final Cut Pro and other NLE applications are concerned, 24F *is* 24P.

No change is possible because it's already 24P to begin with. Hope this helps,

I read the 24F mode loses a lot of vertical resolution to achieve the P look. Can anyone confirm or deny this? It would be great to know.

You heard wrong, it only looses 10% to 20% on some reports, but considering after all has been said and done, the frame mode has more rez, than the HVX200. So I wouldn't worry too much about it.

It's about 10% of the vertical.

As far as "changing" 24F into 24P... allow me to state that in a different way. When you capture 24F into your NLE application, the capture process itself is the change, if that helps how you're looking at it. Final Cut Pro, Grass Valley / Canopus Edius, Adobe Premiere Pro, etc., they all capture 24F as 24P. Once it's in the computer, it's 24P.

Perhaps the film transfer house in question is using Avid? One of the few NLE companies that are still not ready for Frame mode.
