1080p has twice the data rate per frame as 720p, but it also has twice as many pixels to compress, so you’d expect the quality to be around the same, but, you could always scale the 1080p down to 720p and get a better looking 720p….

Also, I think there’d be less detail per macroblock in 1080p so it might end up being more efficient.

I have the 17″ JVC monitor in for testing. At 720p you don’t see all the detail that I can see on my 23″ cinema display+hdlink+decklink HD Pro combo. At 1080 it’s noticibly deficient in resolution. Colour seems fine, but then again, I have no complaints about the colour on the LCD. The only issue with the LCD is interlace doesn’t display quite right.

The compression for the audio on DVD is very slight, so I’d be guessing it’s more the fault of the mic pre-amp in the camera than the HDV audio itself.

Looked, to me, to be Varicam edited in FCP, with effects in Motion, and music in Soundtrack (I recognised some of the stock music).

I think 1080p24 should work out looking better than 720p24, but at the moment, that’s just a guess until we get the camera to play with.

For slowmo shots, you could shoot either 1080i60 or 720p60. I don’t know which would work better, but it will be interesting to see…….

I think you’ll find that PhotoJPEG75% is better even than DV50, and nearly the equal of uncompressed. There’s no point going beyond 75% to 100% as PhotoJPEG100% is RGB(4:4:4) whereas 75% is Y’CbCr(4:2:2) which is still overkill for hi8.

Bring in DV over SDI leaves the lines top and bottom black – it does not give you 486 lines as 486 lines were not recorded – it just does the equivalent of what you’re doing in FCP, puts black lines at the top and bottom to pad the image out to 486 lines.

Scaling DV does not work, as you get a really soft image. I could write a filter that does, like a couple of pixel mirror to fill the top and bottom black bars with faked in picture information, if that would help though.

Thanks Duncan!

Thanks Walter – I should have said 720p25 DVCproHD native, is not FCP supported, whereas uncompressed, or photoJPEG etc. 720p25 input via SDI is!

Sorry, I think it’s the 720p25 that’s not supported by FCP. FCP does support 1080i50, which embeds 1080p25 just fine – there’s no real difference other than how they look, just like you can broadcast 576p25 on in 576i50 PAL.
