New: Canon Rebel T2i Digital SLR

Bob Krieger · February 14th, 2010, 05:14 PM

Very cool. Thanks for the replies. But... 720p60? Is that slomo only? I'd definitely like to shoot 24p for the "film look" idea, and a DSLR is perfect for what I want. Everything I do, so far, will be mastered to DVD or to the web (Vimeo, specifically). Blu-Ray isn't in the picture yet, not with my clients!

Shooting exclusively in 720p wouldn't be a bad thing, I guess. Maybe shoot the 1080p24 things with the T2i, any slomo with the 720p60, downconvert the 1080 to 720 and enjoy. Or I could shoot 720p30 with my T1i and slomo with the 720p60 T2i, and call it a day.

I just think it's strange that the 60/50 fps is on 720p and SD only! Hmmm... interesting.

Update: Download the Rebel T2i / EOS 550D operator's manual.

What are the HD recording limits on this baby?

Jenn Kramer · February 15th, 2010, 01:49 AM

HD recording is limited to the same specs as Canon's other HD SLRs. 4 gig or 30 minutes in SD mode, 4 gig or roughly 12 minutes in HD mode. You can keep taking clips up to that length till you fill up the SD card.

Thanks for posting the manual. On page 228, it states the file size for 1 minute of 1080 or 720 video as approximately 330 MB. Divide that by 60 (per second) and multiply that by 8 (from Bytes to bits), gets us 44 Mb per second.

I note the Canon 7D's manual uses the same figures as the 550D. I feel I'm tiptoeing into nerd territory here, but where the 7D's manual says MPEG44 AVC, the 550D's manual says MPEG-4 AVC/H.264. Hopefully this is just tidying up their nomenclature.

Taking into account that this is all speculation, variable bit rate et al, are we pretty safe in establishing the video side IS pretty much identical to the 7D?

MPEG-4 (did it really say MPEG44?) is a standard that consists of several sub-standards for video and audio. MPEG stands for Motion Picture Expert Group. I believe that AVC stands for Advanced Video Codec. H.264 is a specific compression codec.

Both cameras use H.264 compression.

Bad news on page 136 of the handbook.

I think that mean that there is no HD Out over HDMI while recording.

But on this site it seems the camera have HD-Out:

The manual says:

If you connect the camera to a TV set with an HDMI cable and shoot a movie in 1080p or 720p, the movie being shot will be displayed at a small size on the TV. However, the actual movie will be properly recorded at the movie recording size that was set.

This indicates to me that it functions like the 7D, namely the HDMI out during recording doesn't fill the screen but doesn't drop down to 480i either.

@Jenn Kramer:

I think the 7D fill the screen if you press the "info" button until no more screen-infos are shown.

It doesn't give you the actual 1080p image, though. It's the scaled image from the LCD screen. If the 7D outputted a full 1080p image without other menu/system data people would be using nanoflashes to get around the 4 gig limit.

yep, the 5/7D's do about 5MB/s :) more or less, depending on the amount of compression used for each frame.

So the 12min time limit is not a constant! The 4gb file size is.

Daniel von Euw · February 15th, 2010, 12:10 PM

@Jenn Kramer:

The 7D outputs 1080i during recording.

It outputs 1080i, but not full screen.

Have you read my links???

I just shot with a 5D Saturday and a 7D (mine) Sunday and used a Small HD DP1 monitor on both shoots. In my case when shooting with the 5D, when you hit the record button everything turns into a stretched 480p image on my 16x9 DP1 monitor. It kinda sucks, follow focus would be really hard visually. BEFORE recording everything is HD, you can cycle through different display options for data, etc with the info button and one of them fills the frame (it is cropped a bit) on your external monitor - it's just when you hit the record button that everything goes black for a second and then pops up as stretched 480p.

On the 7D, everything just stays the same when you hit the record button. If you selected "full screen view" via the info button - it just stays that way, the focus box thing goes away and a little red dot shows up in the upper right corner. Visual follow focus is very easy with an external monitor.

This is one of the reasons I got the 7D and not the 5D. Hope this info helps.

'Full screen' to you may mean something other than it does to me. Full screen to me would be the 1920x1080 16:9 recorded image displayed in it's entirety. The 7D (and presumably the T2i, based on the manual) displays a 3:2 display scaled to fit in the 16:9 space with a grayed out top and bottom to frame the 16:9 recording area and black pillarboxing on the sides. I can post a picture if you like, I have a 7D sitting right here and I've used the HDMI out while recording before.
