Starting with 60 fields per second just rescale the fields into frames to get 60 frames per second. In the context of slow motion for sports, rescaling the fields in 60i to 60p and slowing this down to 30p looks far better than starting with 30p and slowing that down to 15p. However, if you do not want slow motion, film in 30p for web delivery.

Any opinions here as to how good the camera is as I'm thinking of buying one?

It's called bob-deinterlacing. It effectively creates two progressive images from one interlaced. It's not rocket science.

This way I could create a 300p file from 30p footage.
And it would be way more horrible than having a 60i image. Try it out yourself.

I haven't seen this tested...
Obviously you haven't. Software solutions are not that good. You cannot make a completely smooth 60p from a 30p file if the motion is even slightly complex. You can from a 60i. It will half the vertical resolution but it's still a lot better than using pixel motion.

But let's not for an instant assume that this is a "normal" workflow, or that this is what is happening behind the scenes in a normal video editing suite when your 60i footage is being deinterlaced.
It has been quite normal for Premiere and AE users as they handle interlacing way better than FCP. FCP does not do proper deinterlacing, it's actually terrible at it.

Frankly, the consensus seems to be that the XA-10/G-10 is a spectacular camera.
Here is a massively detailed review of the camera:

See! I knew we could get there if I only held my breath long enough!!

If you want to read up on Bob Deinterlacing, here's a small snippet from Wikipedia:

"Simple doublers (Bob and Linear) display only one half-picture at a time. Nevertheless, the quick alternating display produces a convincing illusion of full vertical resolution while playback is running."

I was wondering why you were getting so red in the face.

Let's take a look at your post once more: "Why on earth would slow motion be a factor for deciding? "

Now I have explained it to you fully. And even when explained you act like you don't get it. Or maybe you do? Very hard to say from that rambling.

I just hope you never recommend 30p instead of 60i for someone who is doing slowmotion again.

As in:

"It's called Bob Deinterlacing" and

"You cannot make a completely smooth 60p from a 30p file if the motion is even slightly complex. You can from a 60i. It will half the vertical resolution but it's still a lot better than using pixel motion."

We all have different interpretations of "fully", that's for sure.

Mikko, you started by stating "because 60 is better than 30". This indicated to me that you equal fields to frames.

Then you went about saying how you can synthetically create half res progressive frames by line doubling. I was sort of assuming that doesn't count as a solution.

I have never recommended anyone to shoot 30p for slow-motion. I would recommend at least 60p. Preferably much more.

I simply stated that going interlaced doesn't magically give you 60p, and 60i cannot recreate the footage you would have gotten, had you shot 60p at the time of recording.

I was waiting for you and Eric to acknowledge that you cannot maintain resolution by doing it your way. If you want to use your "60i method" as a creative choice, of course that is totally up to you. Just like people adding grain to clean footage for effect.

But I felt it was important to clarify what 60i is and isn't. And it isn't 60p.

Unfortunately, the HF G10 doesn't support 60p, so you'd have to use another camera for that.
