Canon EOS Rebel T4i Has Clean HDMI Out. Almost. *UPDATE*


Guy Thatcher over at Hire A Camera got his hands on the new Canon EOS Rebel T4i. There had been some rumblings that is has a clean HDMI out signal over at Cinema5D. However they had a prototype model and it could not be 100% verified. Well it looks like the new T4i does have a clean HDMI out at 1920 X 1080. This would be a huge bonus from this sub $1K camera. This shows that clean HDMI is possible, let’s hope Canon is generous enough to add this feature via firmware updates to all existing EOS cameras like the 7D and 5D3. Now I just wonder if they will start making 4:4:4 pro res recorders for the soccer mom set. Here are the specs of the Canon Rebel T4i.

Guy Thatcher was able to do a little more testing and indeed the HDMI out is clean…..for about thirty seconds! Make your own lameo sound effect here! A little dissapointing but there may be some potential here. Magic Lantern may have a hack and there may be future updates. For now this looks like a bust in Cine world but may live on in other forms. Here is a rip from the Hire A Camera post.

“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.  Okay so nothing very exciting but pressing the info button gave me this –
Firstly whilst the signal is 1080, it doesn’t fill the full frame.  As you will see below, when I crop the actual frame to fill it, we end up with a image of 1619 x 910 pixels so it’s not filling full 1920 x 1080 – it actually works out it’s only showing about 85% of the picture.  Below is the result.
Second (as this is a biggie), I cannot get the live view to stay on for more than 30 seconds.  Yes you can press buttons to keep the camera going but the minute you do that you get info come up on the screen as below –
So.  In answer to the question, does the 650D have a clean feed, the answer is you decide.  Whilst the feed is 1080, it doesn’t fill the frame totally and you can’t hold that for more than 30 seconds without the live view switching off.  Clearly you can’t adjust anything whilst you are recording as the information will come up on the screen (unless of course you use a manual iris lens).
Put simply, it’s most definitely not like the Nikon’s.  Whether you want to work around all the compromises is completely up to you.”

    Okay, it’s not quite all good news and this needs to be put into some perspective.  I only got to play with the camera for 20 minutes yesterday and whilst you can get a 1080 feed clear of info out of the camera, there are some huge caveats which I have been looking at further this morning.  Whilst it is a 1920 x 1080 output, It only covers 85% of the screen, not 100%, and it puts a light grey frame round it.  You’ve then got the problem that live feed will only stay on not recording for 30 seconds and the minute you press any buttons to keep the camera going, the info will appear on the HDMI feed.  So it’s in no way great.  Big shame.
