Guy's I'm getting (*.....) 6 dots now instead of my previous 3 (*..) thanks to @menoc a lot of memory been freed-up Record Past 5GB with Zero Hick-ups Zero problems Here is a picture:

Guy's $180 dollars left to put in for donations Let's get it done for the 50D contact @JulianH for info.

Actually, the only setting that affects Shooting malloc is High ISO Speed Noise Reduction. Turn it OFF.

Thanks for update Menoc..

Here's what my shooting memory allocation reports after turning off High Speed Noise Reduction . . .

I've had inconsistent results with the read/write tests, that dont correlate to recoridng performance.

If I set FPS override to 0.15fps I get 60+mb/s, if 24fps I get 50ish, if 30fps I get 40-50+

So either the test is inaccurate if fps override is on, or there's something slowing it down in camera when it's at the higher frame rates.

Either way, regardless of what the speed tests indicate I seem to be able to record continuously up to about 55mb/s.

I'm finding that once you turn off the noise reduction it frees up the memory and you can actually turn it back on without affecting the free memory.  Also noticed no difference in frames captured at 3200iso with noise reduction on or off.

What the.... Surprise!

I had global draw turned off all the time. Thought that would take a hit on performance.

Just turned it on (Live view) and guess what, recording speed goes up! Getting stable 1592x896 now, recording at 57MB/s. Without GD i get like 52 and drops to 50. great!

Lets try how far we can get in 5x zoom. I'm getting 300 frames at 1720x968.
1600x900 is stable.

Super work guys. I'm shooting  720x1280 24fps at 37MBps and only (*....) with the original build on a 60 MBps Sandisk card I got yesterday. I'll PM Julian to pony up $20 for taking the lead on the development camera and I wish I got anywhere near as much value and fun from my other donations.

Great find!!!

(and it makes sense, since the 50D ML kills all Canon drawing code)

Tip: turn it off and call canon_gui_disable_front_buffer() from somewhere.

LOL weird stuff. For me it's the exact same opposite at 1592x896 with my 64gb komputerbay 1000x... Global draw on liveview and it stops after about 80 frames. Global draw off and it's at 12GB right now without a single skip :)

Wooohoo.. new trick to add to hacked mode. Esp.. for 600D/550D/etc.

Sick stuff: Global draw on liveview (but I have now all draw options disabled) and resolution at 1600: I can almost record 3:2 resolution:
1592x1062  1103 frames  8) (needed write speed 67,6)

Komputerbay 64gb 1000x (aligned at 4096)

edit: 5x zoom gives me a pink liveview....

BUT runs stable so far at 1920x818 (2.35:1) (62MB/s)

Recorded continuously to 4gb at 1920x818 in 5x crop mode on a Lexar 1000x 16g card.  Stars got up to 4 near the end but it made it to 4gb.  Not very sharp but some L glass might help this.  A lot of jello too...

Wild. Good find. Testing tonight.

I really feel a shared experience with this thread - I've recently bought a second hand 50D, and still waiting for a KomputerBay 64 GB card to arrive!

I bet you could do it if you kill all drawing with Clear Overlays . . .

Guy's we need everybody to contribute towards @JulianH purchase of a 50D for developers 1% he was kind enough to take that risk anything that you can give will help, like a posted before a $10 + is great got a long way to recover his expenses.  Let's make it happen guy's send him an email he will send you the info for donation we need everybody, we have the power to make the 50D shine with those contributions.

I'm in - and have been in touch with Julian.

Hello everyone,

First off thank you very much for all the effort being made to make the canon 50d able to shoot raw video it's been an awesome great experience.
however i'ave some doubt's. im currently using the Greg's 28 may built, with a sandisk extreme 60mb/s udma 8gb card. im getting about 38mb/s stable wich makes me able to shoot in 1280x720 without any problems, i can get away by shooting in a bit higher resolution by comprimessing height. when i warm up the card i can shoot about 41mb/s without any problems.
Globaldraw on my camera with only peak focus enabled makes my write speed about 23mb/s so not good.
i also have download the nightly build however it doesnt come with raw movie module and the only way to get it is by replacing the autoexebin file and placing the modules folder also wich makes not using the nightly build since im replacing the autoexe bin file.... how do i use the latest nightly build and the raw module at the same time?
Ok so, lets say i have recorded some raw movie footage. i want to edit it. i use raw2dng to convert to a dng file wich is at color deph? 14 bit? because i export the dng files. open them in photoshop and the camera raw give me rgb values that are in 8 bit mode range not more than that. however. i open a dng file in after effects, and the rbg values are in the same range as photoshop was giving me. if i change the project settings to a color depth of 16bit the values change and are much higher like a true 14 bit file should be however, i export the movie file in a openexr open that file in nuke and the values are a 8 bit file.
that being said why is my camera shooting in 8 bit color depth mode not in 14 bit... or am i doing something wrong? is the dng file that raw2dng makes a 14 bit file? because my investigation dont indicate me that :/
i was expecting the dng files being a 14 bit image not a 8 bit color mode :C
well sorry for my poor english im from portugal.
thank you all for the effort being made to create this awesome hack :)

That is exactly the post I wanted to see! Have  60Mb/s cards that write at 44.5Mb/s. Keen to try 720 work flow all way to vimeo.

Holy mother of God!! . . . . I'm getting FULL FRAMES stable  3:2 !!   

Did like 12GB with no frames skipping! . .  .WE HAVE TO GET FILE SPANNING WORKING!

Disabling the front buffer lets me preview with no loss of speed it appears.

High ISO noise reduction is really interesting, it reconfigures memories... some blocks become blue and your green blocks move around. I guess on 50D it actually frees the memory its not using.

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

Results im getting with my sandisk extreme 60mb/s UDMA 8 gb card

Hey John here are some bitrates for 50D in each mode, in 24fps/16:9 ratio:

640x480     - 9.2mb/s
720x406     - 11.6mb/s
960x540     - 20.7mb/s
1280x720   - 36.9mb/s
1329x742   - 39.2mb/s
1440x810   - 46.7mb/s
1592x896   - 57.1mb/s   (max res unless using 5x zoom)
1600x900   - 57.6mb/s   (5x zoom only)
1720x960   - 66.0mb/s   (5x zoom only)
1880x1056 - 79.5mb/s   (5x zoom only)
1920x1056 - 81.2mb/s   (5x zoom only)
1992x1056 - 84.2mb/s   (max res for 5x zoom mode)

As I mentioned earlier, despite speed tests showing 40-50mb/s I can happily sit at 1592x896 24fps until 4gb. The fastest rate it's shown while recording is 58mb/s.
