Does the Canon Rebel T4i / 650D have clean HDMI out?

by planetmitch4 Comments

It has been reported (@cinema5d and others) that the new Canon Rebel T4i / 650D (which is now available in many stores) exhibits clean HDMI out! However, the folks at Hireacamera have done more research and report that it isn't as good as originally hoped.

I had previously written to my Canon contacts to ask them about this issue but I haven't gotten any reply yet.

We got our hands on the new Canon EOS 650D yesterday and I was keen to see two things – what was the autofocus like and what feed was coming out of the HDMI.  Now I only had twenty minutes before catching a train and battery was just about empty as straight out of the box so it was a quick look.

The autofocus I'll talk about another day as I'm going to do a comparison against some other cameras.  What I do want to address is the HDMI feed as it seems that things are going round the inter web saying it's completely clean.  

First thing I did was put a monitor on it and I could see it was at least outputting a 1080 signal.  It looked something like below –

Okay so nothing very exciting but pressing the info button gave me this –

  1. Apparently, the initial report by Johnnie Behiri that this had a clean HDMI output is incorrect, it is a scaled output that will not play well with external recorders. Oh well, it was fun while it lasted!

  2. So, it is outputting a 1080 signal, right? Isn’t that an improvement over previous Canons that output some weird cropped resolution? Providing that Magic Lantern could get a clean HDMI signal out at this resolution, wouldn’t that be the first low end DSLR to be external recorder-friendly? Maybe I’m missing something. Anyone know?

  3. From what I understand, that’s correct, however, that 1080 output only lasts 30 seconds before it scales down. Also, I believe I read in certain situations you’ll have menus appear.

    Yes, IF magic lantern creates a clean hack it would be the first low-end DSLR external record ready. In fact, it would be a first Canon DSLR camera period to have this, I think.

  4. Too bad we always need hacks, but I guess the Canon DSLR is still meant to be a journalist camera. All the news paper shooters I know use the 60d, etc.

    Still the 720 output on the 60d is ok with me, enough anyway to stay in frame.
