Re: Something new from Canon on Nov. 3rd...
In my opinion the Sony F3 is the target. When I look at Sony's camera I can definitely see Canon coming up with a product that competes with it. The downside, however, is that you're never going to see a sub-$10k camera with those types of robust features.
At this point, though, it's only a guessing game as to what Canon's intentions are. The good news is that we'll all know soon enough. LOL! But speculation is what's so fun about forums like these -- a collective of happy hand-wringers Mwahahaha'ing the possibilities. |

The AC160 is pretty much the same cost as the AF100. So how come the AC160 gets a P2/AVC-Intra big brother in the HPX250, but no equivalent for the AF100? |

1) Expose properly (that's the goal, but some extra headroom can save expensive, non-optimum footage.) 2) Get the S-curve and gamma just right, and 3) Don't grade. But if you want to fix a non-ideally exposed image, mess with it's curve, and grade colors beyond reality while maintaining smooth gradients and natural texture, you need more bits.

Re: Something new from Canon on Nov. 3rd...
Oh Chris! I've ignored this whole thread until your post. I have an XF100 and I can just imagine using my Canon lenses with a large sensor on that camera; OMG that would be nice!!

Re: Something new from Canon on Nov. 3rd...
Hey Charles, how about this one. You remember 16mm and 8mm cameras with three lense rotation mounts. How about an internal rotation mount for two different sensor chips on the XF-100 type camera. Then you could switch between current XF 100 chip, and a larger sensor. Add interchangealbe EOS lens capability and you have a lot of needs covered in one camera.

So either use the whole sensor, downscaling to 1080p or recording RAW - or just use the centre quarter area of the chip, which will be 1920x1080, and roughly equal to Super16 (?). (And with resolution equivalent to the XF100.) One point that's worth mentioning is to do with the idea of two cameras sharing the same chip, a more expensive camera and a cheaper one, like the F3 and FS100. If we assume the S35 chip, and assume it to be a Bayer of 3920x2160, you could either read it in the normal way (to get such as 4k RAW) and then deBayer, OR treat it in a far simpler way. It could be considered as a 1960x1080 matrix of blocks, each: R G G B So treat each block as a single three colour pixel, and you very simply get full resolution 4:4:4 1080p. No need for de-Bayering, downconversion etc etc. So the more expensive camera gets full 4k ability (and possibly this mode as well), the cheaper one "just" gets the 4:4:4 1080p. |

The simpler option is equivalent to reading from three 1920x1080 chips, directly getting a R,G,B value for each 1080 output pixel. So no deBayering, and no downconversion - it gives 1080 directly. The only difference is that the R,G,B photosites are sitting side by side, not on three separate chips. (And there are two green photosites in the 2x2 block, but they could be averaged together.) I suppose that depends on definition. I see what you mean, but "downconversion" tends to be used in relation to taking a higher definition video signal, and converting to that to one of lower definition. That's not the same as would be happening here, the lower definition signal is being formed directly on read out. |

Re: Something new from Canon on Nov. 3rd...
Not always the case, but it's more that 8 bit formats can probably manage the productions that most people are actaully shooting.
There are trade offs going on in a camera design and you may find that you can have other 10bit codec, but because of compromises in keeping the cost down, other aspects of the camera's design don't in reality make it that worthwhile. It may be better having lower compression 8bit rather than higher compression 10bit. |

Re: Something new from Canon on Nov. 3rd...
The problem with using the word ULTRA is.... then what? What do you call the codec once you implement 1080p 4:4:4? AVC-MAX? And then what? What do you call the AVC flavor that supports 4K in the future? AVC-SUPERDUPER?
