Awesome. Thanks for that.   :)    Have been finishing off edits so when the Camera finally gets here I wont have any distractions!  Although hoping to get by on Sandisk extremes in short term, will be getting a bigger and faster card when I can work out best deal that can also be shipped to NZ.

Can you confirm what resolution and frame rate that is please?  And what speed it is writing at? Thanks.



With Komputerbay 64GB 1000x card:
Runs non-stop stable @ 1592x1062 (I stopped it at 13GB), at about 64 mb/s
@ 1592x896 it will run forever . . .

Set the following:

ISO:  100-200
FPS override:  23.988

Canon Menus:  Set Qualiy to JPEG Only
Disable all settings in C.Fn II: Image
High ISO speed Noise Reduction:  Disable
Auto Lighting Optimizer:  Disable
Highlight Tone Priority:  Disable
Long Exposure Noise Reduction:  OFF

Global Draw:  LiveView (Turn off all other options)

Don't know if it has been discussed yet, but my screen goes pink with the LV image overlaid below when I'm using 5x and 10x zoom. Returns back to normal when I disengage the zoom function. That is using the 28may build by gregoryofmanhattan.

Known issue. It's a work in progress . . .

I've noticed a lot of people getting differing results with the komputerbay cards. Might this have something to do with the fact that they were exposed as actually being Lexar cards that failed quality control?

Anyone else notice the weird square noise pattern on the dngs? Here is the same frame with max sharpen in AE to highlight it. Second frame has blur + noise before the sharpen. turning off sharpening in ACR doesn't seem to help.

Great stuff :) My card is actually the limit now. Maxes out around 59MB/s, recording stable between 56-59MB/s.
So 16:9 1592x896 works fine.

I'll have to get a faster card though, I'd love to use 3:2 and 4:3. 1440x1062 + 2x anamorphic lens is going to be great.
The 50D now officially became the most awesome camera for anamorphic shooters on a budget :)

@primemultimedia: what iso are you on? Can you upload some DNG's? At high iso's when you do a lot of noise correction you can get artefacts like that. It is a pretty old sensor after all... the 50D was known for it's banding problems at high iso in photo mode.

@primemultimedia
Just a guess: It might have to do something with skipping pixels. As I understand it right only a part of the sensor pixels are used.

Probably something like this:

1001001001
0000000000
0000000000
1001001001
0000000000
0000000000
1001001001
0000000000
0000000000
1001001001

when using crop mode the sensor pixels are used like this:

000000000000
000000000000
000000000000
000000000000
000011110000
000011110000
000011110000
000011110000
000000000000
000000000000
000000000000
000000000000

Where a "1" indicates a pixel is used for recording raw.

You could try to use crop mode and see if that helps.

Duplicated the above results. ISO seems to make no difference. The 5th star in the buffer never stayed on consistently. This is getting pretty stable. Now once I get a CF reader back and some glass I get to stop shooting my body cap and film something of substance. Has anyone had luck with joining the spanned files in Terminal?

Yep same here.

I've only noticable when zooming right in/pixel peeping though... I'll check a few 5x and 10x screen grabs and see if it looks the same.

Might be from the downscaling, as mentioned.

Just started testing with the May 28th build with the settings menoc listed and a Komputerbay x1000 64gb.  I get fairly steady results at 1592x1062 with an average of 67 MB/s, but for some reason my camera keeps dropping down to 22.331 FPS. My screen changes exposure when it happens and it usually occurs while I'm recording... It seems to be stuck at 22 fps until I reboot the camera.

I also get a "scripts dir missing" message when turning on the camera, not sure if that's related.

Did you put FPS override on Exact FPS? (press FUNC when you are on the setting in the menu to get more options)
Just make a emtpy folder 'scripts' in the ML directory on your CF card. That will cancel the message.

@Ciardi: looks good!

The build you are linking is not the May28 build, you should link (and use!) this one:
https://bitbucket.org/GregoryOfManhattan/magic-lantern/downloads/50D-2013May28build.zip

See: http://www.magiclantern.fm/forum/index.php?topic=5586.msg43359#msg43359

50D cinemascope is coming - but i'm dropping my main ML dev machine at apple store this morning (down to a single usb port on mb air - so i can't plug in drives and card reader at same time)

build code status: over past couple of days, there have been many conflicts with 50D code and new features.
best stable running builds have been the 28th, morning of the 30th (wish i'd kept that one around).

there will be a different set of resolutions available depending on the mode.
Code: [Select]
RESOLUTION_CHOICES_X CHOICES("640","768","960","1280","1344","1472","1600","1728","1856","1920","2048","2560","2880","3584")

aspect_ratio_choices[] = { "3:1","2.67:1","2.50:1","2.39:1","2.35:1","2.20:1","2:1","1.85:1", "16:9","5:3","3:2","4:3","1:1"};

the 50D in raw mode will drop the width to the maximum available in LiveView - approximately 1536 pixels.
in zoom mode, 1920 is possible.

camera card writing speed will limit maximum resolution - seems like around 55 MB/s is maximum even on cards that benchmark at higher speeds.

for 16x9 HD aspect  shooters:
Resolution  : 1536 x 864
Frames      : 2946
Frame size  : 2322432 bytes
Frame skip  : 1
FPS         : 24.000
Processing frame 2946 of 2946...
Done.

Resolution  : 1920 x 768
Frames      : 2080
Frame size  : 2580480 bytes
Frame skip  : 1
FPS         : 24.000
Processing frame 2080 of 2080...

FWIW - thought i let people know that graphics enables works with the released 28May13 build stable at 57MB/s

speaking of graphics draw, recent builds have been doing weird things with it and that needs to be sorted out as well.

will be online less frequently until i get my computer back.

I think it's of important matter that specific needed changes for the 50d are merged to the unified branch as soon as possible to make sure there are little conflicts in the future. Then it's easier to branch of the unified code to play around a bit :)
Is there an overview of specific 50d stuff? Can't be that much code I guess?

Thanks all of you guys for the donations so far. I got a lot of response and PM's and after one day the funding for the camera is almost complete! (€ 52,60 left).

I think it will be a good idea to supply 1% with a fast CF card as well, since he only has slow ones. I'm suggesting the 64GB Komputerbay 1000X, cheapest I can find on ebay is about $120.

I'd like to finish the funding of the camera first and then keep the donations open for a little longer to fund the CF card. If you want to help, send me a PM and I'll send you the instructions and donations overview! Everything counts, even a few dollars/euros are welcome.




camera card writing speed will limit maximum resolution - seems like around 55 MB/s is maximum even on cards that benchmark at higher speeds.
I'm getting a bit more out of my card, 59MB/s, but that seems to be the limit of the card rather than the camera, as others have reported getting 1592x1062 recording stable (thats 60+ MB/s).

@JulianH

Good call on sending the 50D to 1%. Hopefully my card will turn up today and I can help with testing.

I'll PM you for donation details.

Thanks for everyone's hard work so far.

maybe getting the Komputerbay card from Amazon would be a better idea? or is it not available for International purchase? where is 1% located?

Guy's uploading some 50D footage to vimeo right now.  Just did a quick gorilla handheld style video just to see how it would hold up will post link in 30mins - 1 hour.
