5D Mark IV HDMI 1.3 port ...what?

Hypothetical question would you rather have Dual Pixel AF or a HDMI 1.4 connection?

I ask because the chip Canon is using could be using all of the high speed digital IO lines that could support the 4K output for that.

actually the current 4K in the DSLR's is a hack job.

the reason being is that the DSP's that are in DiGiC are not supporting anything over 1080p.

the video feed from the sensor, to DiGic and output as video is a 1080p stream.

how they get 4K is reading the sensor really fast, and buffering 8mp JPEG's. that's easy to do, and every little heavy lifting compute wise, as long as the sensor can handle being read that fast.

that's why it isn't coming out of the HDMI port, and that's why it's not h.264,etc.

for a while now, the theory was that TI does DiGiC for canon.. this is their best DSP.

You gotta give Neuro some credit. He's fighting a tough battle here for Canon. Sometimes though, it is futile.

But this is one area where Canon cannot make an excuse.

Which is why I stated:

I'm not excusing Canon's statement, just pointing out that there be more considerations at hand than 'a working chip'.

As pointed out above, one valid reason might be they don't see a need for 1.4, 1.3 does everything they need, and it's likely cheaper. Same rationale for a Digic 4 still being used in the xxxxD line in 2016. To me that rationale makes the most sense...but it also makes the initial statement about timing a lie.

To be fair, Canon are very slooowwww in the development phase, so normally this could make sense (the 5DIII lacked USB 3.0 right?), but the lag time and Twitter response is too much of a fib.

Using HDMI 1.3 is a convenient excuse not to provide 4K out, and to cripple the camera for any Magic Lantern hacks that could materialize. You can bet if it had HDMI 1.4 the Magic Lantern folks would stop at nothing to hack that for 4K 4:2:2 out.

The sad part is that there is no full frame 4K video solution from Canon at the moment. They could sell so many more cameras. Yes, I know they're apparently not sweating it- blah, blah, market research. But combined with the crippled features and now these lies, whoops, I mean- excuses- on Twitter, it's all pretty disturbing from a company we want to trust.

Maybe there will be third party producing new badges for the camera with the addition "C" of crippled.

So it will state: 5D Mark IV C

Magic Lantern version would be: 5D Mark IV ML or 5D Mark IV B...for brilliant.

:D

Brilliant! They will discontinue the 1DC and all further 5D releases will come with the "C for Crippled" branding.

Which suggests the Cinema range is using a different DSP, and therefore Canon could use it in a dSLR in future if they felt the need ?
