1080/60i - Blu-ray compatible but it's interlaced and wont down-convert to SD as well as progressive (or so I've heard)

1080/30p - Good option for downconvert but not compatibile with Blu-ray

1080/24p - Accepted by Blu-ray, not sure about downconvert but not brilliant for slo-mo and blurring filming dancing \ motion.

so which is best to use?? or are my assumptions about the formats BS :)
 
With a decent player/TV you can deliver 30p in 60i wrapper (Known as PsF or 2-2 pulldown). The player/TV will reconcile 30p on playback. Same with regular DVD.

2-2 pulldown is supported by most modern Blu-ray players, but by few DVD players. You mileage may vary.
 
I've encoded to blu ray using Toast 9/10 on a Mac with both 1080/24 and 30p.

This was AVCIntra footage, but there wasn't an issue at all even though 30p isn't in the spec.
 
I would forget all this 1080p nonsense and just delivery in Blu-Ray 720p60. This way you deliver in the highest quality progressive format and get 60 complete frames per second for awesome motion rendering. Remember video is all about motion so to me thats the priority.
 
I second the nomination for 720/60p. It's a standard delivery format, downconverts perfectly to SD, and is ideal for making slow-mo from.
 
A lot of people are saying that 720p is a dying format and as soon as 1080p50 and 1080p60 broadcasting starts up this will be the final nail in the coffin for 720p. However this is not so says the BBC British Broadcasting Corporation. In the most recent BBC white paper is was found that 720p75 is subjectively better than 1080p50. The BBC is seriously considering a 720p100 format as its next generation high definition format. This may seem like overkill however for sports whip pans are unavoidable and sometimes not even 100 frames per second can keep up. What the BBC wants is a profesional 720p300 camera that can downconvert to 720p100, 720p50, and 720p60 natively for worldwide broadcasting as well as for awesome slow motion capability and higher temporal super sampling so that the shutter speed can be adjusted in post.

Sounds like a HMC on Speed!
 
On a serious note. Plasma screens actually work better with larger pixels, they are more efficient. This is because each pixel in a plasma screen is effectively a mini fluorescent tube. So maybe 720p is the future!

Yeah, right. Modern plasma and LCD TVs have 1080-line panels.
 
And lets not forget the possibility of the new 1440p diamond pixel displays with pixels that are rotated 45 degrees. These displays will have a raster of 1280 x720 diamond shaped pixels and another raster of of 1280 x 720p interpolated pixels that fill up the holes left in by the diamonds. The interpolation will be very high quality because they are based on the values of 4 surronding pixels. Such displays may be marketed as 1440p which would be the diagonal resolution of the display.
