Hi,

The Canon EOS Rebel T2i, (or 550d) as it is also known in some markets has the following video specs:

Video Recording
Video with MOV (image data: H.264; audio: Linear PCM (with internal mic: monaural, with external mic: stereo))

Video Resolution
1920 x 1080 (Full HD): 30p (29.97) / 24p (23.976) / 25p, 1280 x 720: 60p (59.94) / 50p, 640 x 480 (SD): 60p (59.94) / 50p), Movie Crop recording in 640 x 480

Video Clip Length
Approx. 12 min. (1920 x 1080), 18 min. (1280 x 720), 24 min. (640 x 480)

My question to you is the following:

With the highest resolution, what kind or "size" of video can you make?? Youtube size of videos, (the ones with the small screen), or full-screen-size on a MBP 15", or perhaps the quality of the video is so good, that it could even be projected onto a wall ?? That is what I would like to understand, what kind of "video camera" one gets when one buys this, (or a similar), dSLR ??

Thank you very much, very kind regards,

igmolinav.

1920x1080 is the aspect, not the size. You can have a 1920x1080 screen at 17" and you can have one at 60". You question doesn't make much sense.

We project 1920x1080 onto theater size screens at the FCPUG.

I don't attend the LA final cut user group but the Boston chapter.

Let me try to explain a little better which I suck at (reason why I am not in academia). A standard definition screen displays 720x480 (4:3 aspect ratio). This is the same whether the television set is 19 inches or 60 inches. True HD is 1920x1080 no matter what the "size" of the display as long as it can support that resolution. So on a 17" mbp that has the screen resolution to 1920x1080, your image will be full size the entire size of the screen. On my 15" mbp (old one) a 1920x1080 is bigger than my screen size because it only has a resolution of 1440x900. My 42 inch plasma tv is 1920x1080. So the same image will fill up the 17" laptop and my 42 inch plasma with the same image full screen while it will be too big for laptop and I would have to shrink it down to full screen.

So, as long as you are projecting with an HD projector, yes you can get it blow up real big, but that is based on how good your hardware is.

See this screen? We were projecting HD edits shot on Canon DSLRs onto this screen and it looked awesome.

Advres - I think you're being purposefully obtuse here... the OP's question wasn't phrased perfectly, but the intention was clear.


igmolinav - the video quality from the 550d is absolutely excellent. 'HD' on YouTube normally means 720p (720 vertical pixels) - the 550d can shoot to the next standard up which is 1080p.

This is a higher resolution than your 15inch MacBookPro, even if you upgraded to the hi-res screen. Projected on the wall it's possible to go very big indeed (remember that the bigger you project, the further away you sit, so you don't really have to keep increasing resolution).

Here's a review from Philip Bloom (a professional film-maker). He's commented on his blog that the 550d footage looks good projected to movie theatre size.

The only real problem with the 550d (I own one) is that it's ergonomics aren't as good as a traditional movie camera. So to make it easy to shoot with one, many people spend extra money on viewfinders and support systems. Check out the 'Zacuto' company for some examples.

I don't care what you "think". I was trying to be clear what he was meaning and I then responded with, IMHO, was a more clear way of explaining this to someone who obviously doesn't have grasp. Thanks for attacking me though when you could have put your $.02 into this guys question instead of calling someone trying to be helpful out.

Your first reply just told him he was wrong, and then followed with some confusing stuff about 'aspect', whatever that is. Did you mean to say resolution?

The answer I gave was complete, correct and clear. In your own words (not mine) 'Let me try to explain a little better which I suck at' .

Sorry to butt in but I have to side with advres, though his response to firestarter could have been formulated a little softer . The question from the OP made almost no sense to me either and while advres's first answer was a bit... unclear, the second one was spot on and not obtuse at all... as a matter of fact it is probably the explanation the OP wants?

However I still don't get what the OP exactly wants to know.. he wants to know if full hd is good enough for wall projections? what higher resolutions (except cinemas) is there to project?
