Achieving 1080p

[Seraphic-]

Hi,

I'm wondering which would produce the higher quality image?

Uncompressed 1080i 30fps capture (Intensity Pro - 4:2:2 - 8-Bit over HDMI) and then de-interlace/frame duplicate to 1080p 60fps. Or lossy 960x1080p capture (PV4 - 4:2:2 - 8-Bit over Japanese Component) and resize to 1920x1080p 60fps.

that would depend
a. on the camera itself (the actual resolution)
b. type of content, motion
c. what type of lossy compression capture?

A: PS3/Xbox360 Console (1080i/1080p support)
B: Gameplay Battles/Events with 3D fast moving graphics/effects.
C: Not 100% how lossy the PV4 codec is. Have to get back to do you on that.

Well, the consoles likely render in progressive (and probably in 720p), and then interlace the output, so I'd think you would get ideal results capping in 720p60.

Well, most games on both consoles run games at 720p. However, when set to 1080p, I believe the consoles up-convert to 1080p, but it is still progressive. Also, games should move to 1080p in the future.

Yes, they up-convert, but that just means resize. Why waste bandwidth when you can capture natively and "upscale" on playback?

Games will only move to 1080p in the future when the successors to PS3 and Xbox 360 arrive. The current generation of consoles simply do not have the horsepower for 1080p. Even Gran Turismo is only running at 1280x1080 and that's supposed to the state of the art.

With regards your two examples, both are sub-optimal compared to 720p60. The reason why is very straightforward - in both examples you are losing 50% of the source image at the capture stage and then you're basically making your PC 'guess' what has been lost. It's a complete waste of time. You may as well capture at 1080i30 and then just play back the vid and let the PC deinterlace it on the fly. Or capture 1080i30 and then apply a smart deinterlace on the capture to get 1080p30.

To further emphasise how pointless your exercise is, the fact is that there are no 1080p60 playback platforms available to play your final vids on. Not even HD DVD or Blu-ray can run that resolution and refresh rate.

If there was to be a 'usable' 1080p option you should be aiming for 1920x1080 at 30fps, but as you don't have one, 720p60 is your best option.

Yup, looks like I'll be sticking with 720p capture for this generation with my Intensity Pro. However, I still need 480p capture. So I need to decide what card to keep and what card to sell. The PV4 for lossy 480p or MonsterX (if I can get it working) for lossless 480p.
