It's hard to tell what iso the camera is really using in live view... I can't tell any more. I've put it on H1, H2, (6400, 12800) but it might be less actually. If I take a picture at the same setting, it's brighter than the live view image. Anyway, it was dark and i shot at f/2.8 1/50s and it looks pretty good to me.

Do buy a 50D. It's worth it for the resolution alone.

Your sunset sky made me happy, I've always had problems with sky colors in h264. Can't wait to get the 50d.

How is battery life doing with raw recording? I heard when recording h264 it drains pretty fast.

@araucaria - I think the latest raw_rec module selects height based on selected aspect ratio.

Thanks andy, but will it let you choose the horizontal resolution and select the hight following the aspect ratio?

@menoc What spped benchmark values are you getting with the komputerbay in liveview/movie mode rather than in playback?

[spoiler]OK,

Komputerbay 64GB 1000x CF card benchmarks;


@ 1592x1062, writing to the card stops after about 50 frames; @ 1592x960, writing to the card drops frames but writes to 4GB; @ 1592x840, writing to the card drops frames but writes to 4GB; @ 1592x720, the 1st try stopped at 100 frames, the 2nd try wrote a 4GB fie without any frames dropped; @ 1280x720, writing to the card finishes the 4GB file without dropping frames.

Here you can download the sample DNGs:

Here's a sample image with the pink tint - is this fixable? (it's really not a big deal- it's easily fixed in post). There's also a black line running vertically on the left side of the image - but you have to download one of the DNGs to see it.

ISO 320/F3.5/23.988FPS

Nice samples!
Could you try using less horizontal resolution and keeping the 16:9 aspect. 1427x802 should have the same pixel number as 1592x720, dunno if magic lantern lets you set that akward resolution.

Zoom LV with Resolution of 1992X1084 seems to be far less disturbed: http://www.smeangol.com/1992x1084_seq.zip
First few frames are rubbish, the recording ends with some dropped frames due my lame CF Card.
This resolution belongs to the normal field of view

Yea that's why I said "crop", just wanted to know if you had any "screen grab" sample of that mode.
Downloading your sequence to give it a try on AE, btw what card did you use? Thanks for the sample btw

I loaded up your dngs in After effects and beside the corrupt images the score seems to be yellowish (after adjusting white balance tint), is it the lighting?
Btw that magenta shift menoc is talking about, is it the wb issue or is he referring to the corrupted magenta colored frames.
I'll make test with different settings if it helps when I got the 50d (ich hab' keine ahnung von programmieren)

This is a dng from a "zoomed in like X5 or X10" shot - in this mode you get a 1920 X 1080 style frame - but it doesnt work perfectly :/
The Normal not cropped /zoomed LV mode should ~ 1500 X 1000 work without disturbance.

Thanks smeangol, do you have any sample dng of the 1500x1000 "crop".
I have a sample posted here on the forums taken with silent shutter which is 1592x1062 and even with the visible aliasing/lineskipping it looks great, even upscaling it to 1920x1080 it looks way better than 1080p h264 footage from my d800, I mean, just the fact of  being able to use ACR on video makes me the happiest man on the world (I'm not a real video guy, I come from stills but people want video).

This raw recording is from the same source as the silent shutter, I suppose.

Hi, I guess this is the typical n00b trolling first post ^^. I will get a 50d tomorrow for RAW video, any reason I should stay away?

Could anyone tell me if the quality is similar to the 5dmkii. I'm asking because I have a d800 and I have been comparing it to the raw shoots of the 5dmkii and they look a lot better indeed, so if the 50d will have the same quality it's defenitly a nice thing to have (despite 1.6x crop). Since I need the d800 I won't jump ships and this seems a cheap way to have an alternative for those shots that make me yell at the d800.

Excuse my manners, I got so excited.
