Raw Video / Re: 550D raw video recording port official thread

If you run the speed simulation script, you would notice that at 1152x460 you get 603 frames if the card write speed is 20.9 MB/s and 891 if the speed is 21.0. For reproducing the results: buffers 32x2+8, 23.976 fps, timing variation 0.

So these reports about slowdown are quite pointless.
I'm using the same card for every test (sandisk extreme pro 95 mbps 8gb) and with the latest build i get around 580 frames with 1152x460 at 23.976 fps, but with previous at least 900 and sometimes 1300. These results are consistent, not random. (magic raw)

Results for tragic raw:
with the previous build i have at least 386 frames at 1152x464
Now with these parameters recording stops everytime after 68 frames.

So obviously something is going on besides the card write speed etc.

Now I´m able to get 240 frames 3:1 1280x426 with magic raw, thanks mk11174!!! 
Previous build gives me 300+ frames 1280x426 in photo mode at 23.976 fps (sandisk 95 mbps).
For me, this last update works slightly worse then previous. For example, i had 900+ frames 1152x460, but now its only about 600. And the previous one worked nicely in photo mode, giving me better results. The last one have some problems with photo mode.
The one great thing is the ability to save settings of the raw-rec modules for sure.

Yeah I got a sandisk extreme 45 mb/s card and it's the same as my kingston class 10 card. Back it goes to costco.
I've got the same experience from my sandisk extreme 45 mb/s: i was disappointed, because it acts just slightly better then almost any other class 10 sd card, but then i got the sandisk extreme pro 95 mb/s, and now i'm easily getting stable 1152x464 for more than 600 frames at 23.976 fps.
It is just a strange “piece of luck” that sd controller bottleneck and write speed of 10 class sd cards are just about the same.
So you need a really fast card to be sure you hit the right one.

Now i'm getting stable 1280x536 (lovely 1:2.4 cinemascope ratio) at 18 fps, and with some effort and tricky twixtoring, i'm pretty sure i can shoot the whole short film entirely within the RAW workflow.

With all the fine detail, dynamic range, beautiful color reproduction and other flexibilities, we can now get a bunch of really shiny shots, guys.
Another color test:

A couple of tests with motion and slightly moving objects. As you can see, this technique theoretically can handle some more complex motion, so this is promising:

My current workflow:
- movie mode with overlays off
- 1280x536 18fps or 1344x576 15fps
- minimal possible ISO of course (for day outdoors usually i use iso 100-0.3 ml ev = 80)
- shutter speed for filmic look is obviously dictated by 180 degrees rule, so it should be around 1/40 - 1/50 sec. (if you are planning using some time remapping plugins like twixtor, the shutter speed shoud remain the same for natural motion blur, regardless of actual fps you are shooting on).
- Raw2DNG
- Initial and most thorough grading in Adobe Camera RAW
- Importing DNG's directly to AE (my slightly overclocked core i7 930 is enough for short tests, but for longer sequences i will use exporting to 16bit tiffs or smth)
- Twixtor pro to frame rate conversion.

guys, how do you embed videos in posts?

This button should help:

Just paste the link between the [youtube] tags.
