I guess I'm blind - on A/B switching the progr looks slightly sharper to me and since it's a static shot, that's to be expected.
But since the shots are not at the same moment in time, various factors could be affecting the results much less firmware. What's more exciting is the nice latitude that keeps showing up in these shots - very impressive indeed. |
To me, this looks IDENTICAL to Canon's "F" mode. You can only really discern it from grabs, much harder to see in real motion. Same is true of the HVX as well. Something about the motion seems to mask the resolution loss.

Why would there be a resolution loss going from interlaced material to progressive? I understand why the Canon F mode is slightly lower in resolution because it is being derived from an interlaced CCD. Since the V1 has CMOS chips that are inherently progressive it must take a special type of balls up!
Did anyone record 30p in the US? If so how did that compare to the sharpness of 60i? |

Quite how you could say this when A/B switching them I don't know. Look closely at the tire detail in the foreground for one. There is one HUGE detail missing from the progressive scan image that seems to have been filtered out (a piece of rubber hanging out of the side near the top of the tire). Look at the drive detail. In the progressive image there's huge swathes of detail missing. Yes, actual detail. This isn't about softness or sharpness, its about actual detail in the picture. As Steve Mullen mentioned, it could be that the filtering is set incorrectly. |

Or should I say - different? Doing away with this tyre piece completely must be some filtering in action, not just softening/resolution loss. |
Now I must say I'm completely lost: I cut out small windows around the tyre detail from both the interlaced and progressive grabs, saved as separate files - and guess what! The rubber detail, so obviously missing from the progressive frame when displayed in whole, is back there!

I believe that with interlace, sensor rows are "paired" to improve sensitivity and reduce twitter. Such that even field lines may be made from sensor lines 1+2, 3+4, 5+6 etc, odd field lines from 2+3, 4+5, etc. My question to Simon is what do Sony have to say about all this? Until we get an answer to that, speculating about technicalities is all very well, but it may just turn out to be an early (and unrepresentative) individual model. |

I think the focus location is slightly 'deeper' into the scene with the progressive.
i.e. The middle of the car is sharper with the progressive but less sharp on the front tire (compared to the interlaced). Both captures look reasonably good though............. with the cautionary note of the mild CA. Thanks for posting JohnG |

I don't suppose it would be possible to post any footage? Something with movement and detail? Cheers TT |

There is no issue with Vegas and this camera. Unlike the clumsiness that is 24p, 25p does not require any special handling other than telling Vegas that it is progressive. Quote:
Look, there are huge chunks of detail that are missing from the progressive images that are not explainable even if Vegas had been set incorrectly (which was not the case). Quote:

Flipping back and forth I see no loss in detail, but rather a change in the sharpening settings.
On the roof edge for example, the interlaced image has a distinct detail-less black halo. The progressive image has a smooth transition to the background. Same as in the driveway, the sharpening enhances the edges of the stones. It's also difficult to know if you're on an i-frame or not. Who knows how the MPEG-2 compression enters into it? -Steve |
I would say that people finally need to start sharing footage. They obviously are not allowed to... but that is what I want to see right now. All this endless analysing of images. It's all about how it looks in motion.
