EOS Bodies / Re: So, what about the T4i?
« on: March 03, 2012, 09:42:28 PM »
The thing that makes me most doubt that is a real T4i picture is, if Canon has organizationally decided that the DOF preview button is better placed to the right of the lens (as on the 5d3), what is it still doing on the left (from the operator's perspective) in that picture?

The HDMI is 1080p and remains 1080p while recording, it's only not "clean" in the respect that it still shows the overlays.  I doubt the live view will work at the same time, why would you want to look at that tiny screen if you have it hooked up to a monitor or EVF?

Because very often on a set you're not the one looking at the external screen. Often the camera operator wants to be looking at an EVF...which a viewfinder attachment can do a decent job of being mounted on the back of the camera body. A separate person--whether they are a focus puller, the director, the talent--will want to view the screen version. HDMI passthrough monitors allow multiple screens just fine as it is, but it would sure be nice to have the on-camera screen running simultaneously.

If Canon can't do this because of processing overhead constraints, OK, but a lot of practical filmmakers have demanded it like they have with many of the other features that were delivered.

EOS Bodies / Re: Anyone sad about no T4i/650D announcement

What I would be excited about in a 650D...apart from the touchscreen capability that has already been leaked...would be the Dig!c5 and if it has the ability to do the lens correction that the 5d3 has. Chromatic abberation, distortion, as well as the 600D's vignetting ("peripheral illumination") correction. And could do so in video mode too. That would make all my EF-S lenses worth more just by buying the body.

And since the Micro-4/3rds cameras have this functionality, Canon would want to add it to stay relevant. I don't know the details of how it works, but if it could be just stored as a starting point when editing RAW stills, so much the better.

Also streaming full-res video out the mini HDMI port would be terrific. The 600D had 3x-10x digital zoom (and the 3X form eliminated the line-skipping moire problem!) on the video, which broke new ground. So 1080p at 60fps? Sure why not that too...and for the skateboard shooter the smaller body would be exactly what they'd want.

There's no reason why the 650D couldn't lead the line in some ways technologically, even if that makes the more expensive bodies seem less-featured. Because the Rebel line is competing against Sony and Panasonic and Samsung, who have bells and whistles on their side. Canon has glass.

I am very interested to learn if the All-I mode is 4:2:2 or 4:2:0.  4:2:2 would be a great help for green screen work.

Canon can always send out a firmware update if their calculations indicate Nikon is hurting them more than cannibalism of the C series would be.

The reason we want uncompressed HDMI output is because the compression is what hurts video quality the most. With a clean HDMI output...not only uncompressed, but free of any camera overlays like the blinking recording indicator...we can attach external recording devices to the camera that allow superior compression or even no compression at all. That is still not as good as RAW format straight from the sensor, but devices are available that will probably do a little better than Canon's ALL-I mode and more will be developed in the future.

So it's a way of future-proofing the camera to a degree. The Nikon D800 offers it and that's a plus.

The other issue with the HDMI output is what resolution is available for an external monitor. Shooting video you will immediately discover that the core problem is pulling focus while you're shooting. Viewfinder attachments onto the back of the camera are one approach, another is using an external monitor. There are focus assist features on some external monitors such as "Peaking" (which outlines in-focus areas as a confirmation) or "pixel-for-pixel" which zooms to a 1:1 display ratio.

The 5DMkII didn't support those modes well at all--the resolution and proportions shrunk miserably. The 7D was a big improvement, streaming 720p, and it appears the 5DMkIII maintains full 1080p while shooting. That is a huge advance for focus pullers if true. Sadly, the 5x/10x digital zoom you use in LiveView before shooting still cannot be activated while recording to assist with focus then...so external monitoring with peaking/pixel-for-pixel is the best available approach right now.

While clean HDMI out is a nice Nikon D800 feature, I'm going to guess that the ALL-I mode's bitrate is quite adequate, and the 5d3's superior low-light performance and other improved functionality makes it retain the crown of best DSLR video system. Sure, Canon may be trying to protect it's "C" Cinema cameras a bit, but a lot of this may simply have to do with the fact it only has one Dig!c5+ to pipeline the data through and that keeps cost, weight, and heat down.

Most likely the 5D3 isn't going to be what kills your film regardless. The script...
