It's very easy to see the difference. Check TV settings aren't deinterlacing or similar.

30p has better resolution, but is worse at motion portrayal. 30p is a more filmic look.

I will always go for progressive (p) over interlaced (i). Much nicer picture and no twittering.
The only real reason to shoot interlaced is it has a lower bandwith so for streaming live sports etc. it has the advantage over progressive.

The general rule for realistic or "filmic" motion with progressive is to have your shutter speed twice your frame rate. so for 30p have your shutter at 1/60th.

Ok thanks il take that on baord

No. 180 degree shutter is a trade off between motion blur and flicker.

Filmic look is to do with low framerate. Versus video look at 50/60

Neither will look realistic. No camera image is realistic.

As I said, 60i will have better motion portrayal. 30p wil have higher resolution.

Im still confused. Can i just ask you what you would use please out of the two of course for best results?

UK broadcasters use 50i for most things, choosing 25p for effect only.

You should use about 1/100 shutter speed with that.

If you're in the US, use 60i.

Yes, the frame rate is a low 30, but the shutter speed is what gives it the filmic as opposed to video look. See this video http://www.youtube.com/watch?v=lItCq5Gp6vw the frame rate stays the same, while the shutter speed makes a huge difference

I fail to see how an interlaced picture can give better motion portrayal as you get twittering like this if your television or monitor cannot deinterlace properly. You will never get this problem with progressive.

Both 1080i and 1080p are the same 1920x1080 resolution.

I am studying film and television at university and my lecturer would kick us we used anything other than progressive. Interlaced is only useful for broadcasting purposes.

If your television can't deinterlace properly, you should get a refund.

60i will give better motion portrayal as its temporal sampling rate is twice that of 30p.

That photo is showing combing, you can't see twittering in a still image.

if he had the option of 60p, I'd agree, but as he wants good motion portrayal then the temporal sampling rate is key.
