I shot video on my Sony PXW-X70 camera. The settings were 1080/50i FX.
I set it at 50i as I wanted to slow down the footage in post.

But when I imported the clips into Premiere Pro, all of the clips were in 25fps and not 50fps.
Why is that? Can I change them?

The clips in the camera still say 50i but in Premiere, it's 25fps.

Any help appreciated!!

50i is 50 fields per second (interlaced) and every frame has two fields so it is actually 25 fps.

Interlaced video is great for broadcasting but it looks crappy on the computer screen. If you have a lot of interlaced video investing in the Blackmagic Design Intensity Shuttle is money well spent.

With the intention of using slow-motion, you'd want to shoot as 50p (or 60p in the US). Then edit as 25p or 30p respectively. Works great for me using that same X70.

Thanks
