Well I just shot 32 gigs of raw movies in 3 files.  I immediately switched over to the SD card (my wav drive) and snapped a raw pic.]
Examining the exif info, the camera temperature was 43C.

I've seen it warmer than that shooting outdoors without any hacks with the standard firmware.  I'm not worried about overheating this 5d3 at all.
Wow! No 4GB limit anymore? Please, give me an answer:)

Thanks! I developed the frames in Camera Raw, and sharpening is part of the usual routine. I also added a 'sharpen for screen' to the output settings. The sharpening enhances the aliasing too, ofcourse, but in my not-so-interesting first part of the clip you can clearly see how bad it is. Also see the leaning flower in the ISO tests.

'Not usable' I think is very individual. I publish for the internet, and the moiré was there already on h.264 from the Mark II, so its no sudden surprise. Compare it to the Mark III, and then its suddenly 'not usable'.. you can fix some (color) moire in Camera Raw, the aliasing seems there to stay, unless you shoot in crop mode.

I think right now the biggest hurdles for the Mark II is the 4gb limit and the resolution limits. Sound you can do externally.

Wotched yours video agan! 2:04 seconds - is so photo like, really great quality!  This test makes me want to mark2:, it`s cheaper and so crisp. If the aliassing and moire at the first part of this video is the worst wat we can see,  i wouldn`t mind. (mabe i have to see more tests).

How long can you recording with 1880x840? (for me it`s really god, just a little upscale and crop to:1920x800)  Until the 4G limit will be reached? I thought that the restriction was lifted) P.S.: What was the export settings to vimeo, please?

Thanks again for the video.

Super sharp and clean, i like it. (did you increase the sharpness?)

Do you think that moire -is the main thin which makes the raw video not useable? Or the moir is not so crazy as we all think. Today i only think about mark 3 because of less moire... But in your video it seems to be good  enough.

Mark2  videos looks much sharper than mark3, that is good for me.

Do you think that the interface can handle 135.3MB/s ( Blackmagic style 2.5K raw @ 2560 x 1320 /24p) if there is a cf x1500 card?

Not all cameras with sd slot can  write on the maximum speed. What it the maximum  write speed to the cf do you think?
Thanks!

Hi! Do you think that is possible to have  a raw zebra?   As i know blackmagic have it.

Thanks! I understand that all pros uses an histogram, but...

Raw Video / Re: Raw Burst on the 50D

According to the samples, max resolution on 50D is 1592x1062 in 1x mode and 1992x1080 in crop mode. Not bad.

50d  is 1.6 crop. with crop mode to 1992 average crop would be about x2?)

in  1992x1080 crop mode the noise would be upscaled too?

Ok... Can it rec 24 fps 1080p?
#58
Can you tell me please: if i render my DNG file in After Effects to cineform 4-4-4 : it will be raw? or just compressed 12 bit 4-4-4?

If you transcode to cineform raw quicktime format it opens in Davinci.

But i think camera settings in resolve (exposition, wb,tint) will be dissabled as in dng files, Or not?
#60
hi! Do you think that it is possible to convert ML dng raw to resolve format (cinema dng)?
#61
thanks! awesome! What was the iso settings?
#62
Hi, again.

Do you think that 1280 x 400 24fps continious raw  is possible for 550d?

What would be the file size of 1 frame at 1920x1080 12bit RAW?

Approximate RAW file
size on a Nikon D7000   12 bit   14 bit
compressed   12.6 MB   15.7 MB
uncompressed   14.9 MB   18.8 MB

sooo. we can see the difference in %. The filesize is 20% less in 12 bit then 14 bit
#64
Do you mean: recording with 12bit dng raw?

Gonna be really cool! 14 bit is too much as  i think and make the file size to big to rec
#65
It would be nice to have 1280x400 as 600d RAW DNG with 24 fps. It should be posible

QuoteMax speed is about a frame every 2 seconds on 550D with a 30 MB/s 8Gb Sandisk SD card
Not bad for timelapsers)))

Can you upload any tetst?:) Please

thansk!

RAW mode 720 vs 480 crops.

i think 720 should have better quality than 480? Or the quality is the same?

This video was shot in 640x480? Wow, 600d makes more blurry video in standard h.264 720p i think.

Interesting to see 1280 x 400 (upsc to 644)

the second clip is RAW DNG?  cool and crisp! Can you upload one dng file? Thanks

Did you upscale height to 664px?

That's where the RGB histogram comes in handy. You can easily watch the red channel in the histogram (since skin tones fall in this channel) and make sure that it's exposed properly.
So much action and histogramm when you can just choose an object and set 0 on the expo line. Easy and fast, and you can don`t have to controll all of the histogramm.

I don't think there's partial or spot metering in video mode, and there's a valid reason behind it. If such a metering mode was selected while the camera is on automatic exposure, the exposure would change dramatically every time you move the camera since it is metering a specific area rather than the whole scene.

I suggest you use manual exposure and use the histogram and zebras. Setting the histogram to luma might be easier to start with since you don't have to worry about different colour channels. You just need to make sure that you have a bell shaped curve, i.e. based in the middle, with as little clipping as possible. Clipping (i.e. overexposed & underexposed areas) occur when the histogram goes outside the left & right boundaries.

Edit: I just read that you're using Cinestyle too. As long as you make sure that the highest tip in your histogram is near the middle, you'll be fine. Also, a quick work-around if you want to meter for a specific object would be to go to photo mode with partial or spot metering, check the reading, switch back to movie mode and dial in those settings while in manual exposure. Can't get easier than that  ;)

Histogramm e.t.c take`s information from all of the picture and create (show) waves.  So you can get nice exposured hightlights and to much underexposed important part of image. That is gonna be really nice to choose part of image which you want to exposure on -.

Try to shoot portrait when sky is on the background and main object is in the shadow. Histogram would be good, but object would be underexposured. So if you focuse exposure meter on the object you would have a good expo. That is like a make right exposure by grey card target

Thanks. But it would be  easy to get right exposure when you choose an object and  set 0 on exposure meter line.

Usually i use a cinestyle technicolor, and   so much hard to get right exposure. Histogram, waveform, zebras, vectorscope - cool features, but provide information that i cant aplly in right way:(

Automatic metering works fine in many cases, but "evaluative mode" is unuseful for many scenes, so opportunity to set "Partial" would be realy helpful to get an accurate exposure.

Thanks again.

Hi! I find that an exposure metering freez   on "evaluative mode" in video mode... I hate this method of exposure metering because it takes all of image and give`s me an incorrect information about exp. The best   mettering mode to shoot a video is "Partial" ( when i can choose an object  to exposure on) but i can`t get it...

http://www.youtube.com/watch?v=CyoEvXrkqck  more about this problem.

It would be brilliant if it would be  posible to make Partial exp. work.
Thank`s a lot for all you do and done for us!

Please, let me know anything about that.
P.S.: sorry for my english.
