So, can we use an Android tabled as a field monitor alternative ? I have searched on google for more details on this subject and I didn't find to much info.

On the market these days there are tablets with mini/micros hdmi ports, can we connect these tablets to the camera hdmi and get a high res video image on the tablet ?

Or if we connect the tablet to the camera on the usb port, does this kind of solution work as an alternative for a field monitor ? What do you guys know about this ?

Well, probably shooting RAW video overheats some component from the camera and eventually kills it. Just remember, those cameras although they support high writing speeds to the memory card, they were never meant to support writing at these kinds of speed for long periods of time, like is done when shooting RAW videos.

Yes, I'm just curios to see what will it do on your clip, because it has more complex scenes.

Well, no matter how good the pocket cinema will turn out to be, I ain't selling my 600D. I am going to buy a pocket cinema camera, but I'm also going to keep the 600D.

You should try with Twixtor to make from 12 fps > 24 fps. Look at this example:

The only worry I have, is that the demand will be so high, that they won't be capable of meeting the market demand and the price will go up immediately after release.

Get a cheap 50d for raw video ;)
Neah, for raw I'll buy myself a nice black magic pocket cinema.

But just wondering, will it also be a pain in the but with the b.m.p.c. post work as is with raw on canon ?

Yes, I know, I know, 600D is a good little camera for H.264, but damn, look at that RAW quality out of a 600D !

If you shoot 720p, what fps can you get ?

Damn ! Imagine what would have meant to have a faster SD controller and shoot 1080p with the 600D. F*** you Canon !

Anyway, you should try to make 24 fps out of 12 fps with twixtor, see what that will produce.

I don't know if the 3x zoom is upscaled, but what i know from experience, is that it gets rid off all the aliasing and moire that you normally get from the sensor line skipping, and the quality of the videos, is better in this way. For RAW video, it sure does a good thing, because RAW videos tend to suffer from this aliasing issue because of the low res.

I think that shooting RAW with 3x digital zoom at 960X540, and then rescale it to 720p, will give you the best video quality the 600D can produce right now, and because the image is so clean, and with virtually no aliasing, you can even upscale it to 1080p and get away with it. But first try to upscale it to 720p, that will probably be the best quality.

Yes, well what can I say ? I too am looking forward for the release of the black magic pocket cinema, that sure as hell it's going to put a dent in the Canon DSLR lineup for filming. I just want to see first some more footage from that camera.

Anyway, about the 600D, yes, I agree, you can shoot raw with 3x digital zoom on other Canon cameras, but you can't shoot H.264, so it's either the 600D, or the MK III, so in this regard, the 600D is king of the hill in this price range. And oho, trust me, since the 3x digital zoom doesn't come by default not even with the MK III, trust me on this one, it is a big deal. Just imagine in the paparazzi sector, how much money it's spend on high powered zoom lenses, not only for taking pictures, but for video also. Don't underestimate the importance of that 3x zoom, it is not by any mistake they have left it out in the newer cameras.

On a 600D, you activate the 3x zoom feature, take a few steps back, and done, no more aliasing and moire problems. Not even the mighty 5D MK II can't do that. A 600D is a must have camera if you are in the video business, if you are interested in cameras from Canon that is.

Or you strap a 50mm f/1.8 lens, activate the 3x zoom feature, and presto, you now have a 150mm lens, with no moire and aliasing, and with god night capabilities. On what other camera can I do this ? Can even the 5D MK II do this ? NOT !

The 600D is a keeper, nobody should give up on this little camera, even if he or she buys a much more expensive camera from Canon.

This 1:1 crop video mode in 1080p, was a slip up from Canon, they have now quickly taken it out from the newer cameras, T4i, T5i, none of them have this feature anymore, and probably we will never see it again to soon, because it really hurts their zoom lens business. Just imagine how much money they're loosing if I want to film with a 800mm lens, and instead of buying from Canon a 3000$ lens, I just put on the 600D a cheap 300$ 250mm lens, and activate the 3x zoom feature. A low cost segment, hurts a high dollar segment from the Canon business, so, that is probably why they have taken it out so quickly, and it was not present even on the MK III. The fact that the 3x zoom feature was not present on MK III, says it all.

Probably the guy who put the 3x zoom feature on the 600D was fired by Canon. :)

Yes, I agree, the 600D/T3i is a good little camera, especially if we consider that only the 600D and the 5D MK III, can get rid of all the aliasing problems, from all the affordable Canon DSLR lineup. That is a big deal, and it seams few realize this fully. Because of this single reason, in my opinion, 600D is a better camera for video than 60D/7D.

Just a thought, but has anyone really checked if the HDMI offers a better quality than the video that is present on the SD card ? Maybe the HDMI goes through less compression, or through a less number of cycles regarding compression.

From what I understand, the raw video data goes first in the jpeg algorithm, then it is passed through the H.264 chip, and maybe on the HDMI, we get only the jpeg compression, who knows ?

And can't we just set global draw:off, and then record to an external source through the HDMI port ?

I have a question. If I understand things right, the 600D feeds a low resolution image to the H.264 codec, then it is upscaled to 1080p resolution, so basically, this means that the 1080p H.264 it's NOT a real Full HD resolution, isn't it ? Well, in this case, what if we match with RAW the same original resolution that H.264 gets before rescales the video ? In that case, doesn't it mean, that we have obtained the H.264 1080p, only this time in RAW ? We just need to upscale the raw video to 1080p just like the H.264 does. Correct me if I'm wrong on this please.
#69
But for the maximum quality (without sound), what settings ?
#70
Yes, yes, please tell us the best settings for H.264 (without audio). I don't understand those settings also, and I can't find any explications.
#71
Flush rate control ? And what settings exactly ? I don't need audio.
#72
How about taking a normal ML 2.3 for 600D, and add the GOP control feature on it, and then release it as a nightly build ? ML 2.3+, or something like that.

Right now, that's all I'm caring about, that GOP control feature, because it's becoming clearer that on a 600D, the raw feature ain't going to happen for 720p@24 fps.
#73
So, you're saying that on a 600D, even with 10 bit raw, it's still going to be impossible to shoot 1280x720 @ 24fps ? Very disappointing.
#74
Yes, it kills me to see how much quality the hacks bring on GH2, and how little improvement bring on Canon. I mean Canon can now shoot at ~160 mb/s, and we get nowhere near the quality improvement that we see on a GH2 shooting at even 65 mb/s. We definitely need better H.264 tweaks, and I still believe it can be done, and I have great faith in the developers of ML that they will manage to crack this problem. AVCHD that Panasonic is using, and Canon's H.264, are related, because AVCHD is just a subset of H.264, and because of this, I know we can get way better quality from the H.264 then we're getting now, if Panasonic have done it, ML can do it too.
#75
You should do another test with the 3x zoom feature, because it gets rid of the aliasing, and shoot raw at 960x540, then upscale it to 1280x720. This would be theoretically the best image quality the 600D can give at the current time. I am very curious to see just how would a clip like this look like.
