So what are you saying guys - raw is now enabled in unified builds for 550d?

@xaint, yes, fps override is constantly on at 18fps, so I am not changing it..

Can someone please check if dng frame sizes are correct? I am getting smaller resolution dng's, than what I have configured in the camera (550d). So for 1408x480 video I am getting 1392x464 dng's ...

One more sample from today 1408x480 @18fps

So.. several bugs to report.
1) Deleting raw files does not work properly and I can't switch from one raw file to another for in camera playback
2) 10x zoom kills camera, so would be nice to have it disabled by default.
3) Something weird going on with aperture and shutter settings. I can't get the logic here, but they seem to be changing when I switch to 5x. Also exposure visually seems to be different after camera restart, though the aperture and shutter settings remain the same. Why are they shown in red btw? Shutter setting seems to have almost no effect, when I change it from 200 to anything up to 4000, only aperture affects the amount of light..Maybe I am missing something?
4) When I extract dng's they seem to be at a smaller resolution compared to settings in camera, why is it so? For example for 1408x480 video dng's are 1392×464.

spent a lot of time trying to find this topic. Looks like it has been moved without any notice. Good that I had my history

Here's another test http://www.youtube.com/watch?v=HRFjtxzRPLk

1344x448 (3:1) @ 18fps

hello guys

i have read that 550d can use sdxc cards is that right?an will this brings more speed.

" Die Serienbildgeschwindigkeit ist nominell von 3,4 auf 3,7 Bildern gesteigert bei reduzierter Serienbildfolge (6 RAWs bzw. 34 JPEGs gegenüber 9/170 einer 500D). In unserem Test ergaben sich im Schnitt 3,5 B/Sek. bei ebenfalls 6 RAWs in unverzögerter Folge. Gegenüber der 500D konnnte die Wartezeit zwischen zwei Bursts von 10 auf 7 Sekunden gedrückt werden, schnelle SD-Karten vorausgesetzt (mit 30MB/Sek.). Unterstützt werden jetzt auch SDXC-Karten ("eXtended Capacity") mit theoretischen 300 MB/Sek und 2 Terabyte Kapazität. Ersteres dürfte die Wartezeiten zwischen einzelnen Serienbildsalven an der 550D nochmal spürbar verkürzen, derzeit sind aber keine höheren Transferraten als 30MB/Sek. bei den SD-Karten verfügbar."

this is from review 2010

sdxc work on exFat.

what if i want to try to format a card to exfat?

will it work?

SD card is not the bottleneck - it's card controller in our camera which limits the write speed.

My today's test 1728x576@12fps

Thanks mk11174! Will continue experimenting tomorrow.. now off to bed..

btw, raw playback in camera crashes it - have to pull out the battery.

1 skipped frame in the beginning, then continuous. I stopped it after 1000 frames

UPDATE: 960x544 (16:9) @ 20fps continuous

I would prefer a 1200 width option back, jumping from 960 to 1280 is a bit too much, maybe even something in between would not hurt.

trying it now! 720p @ 12fps

@NedB, cool! Meanwhile I ran some side by side tests of my Lumix GH2 with 100Mbps hack ([email protected]) and 550d at 1200x400@18fps raw and I see that Canon is not even close in terms of details.. Maybe I am not doing post processing properly? I convert with raw2dng, then export dng's to 16 bit tiff and then encode with ffmpeg using lossless libx246... One thing I noticed is that my video suffers from magenta

see the result http://l.bitcasa.com/MhTBidmb

mk11174, can you share the build you run stable at 960x480? I did not quite understand what I need besides the latest nightly...

aha, so choosing x5 zoom will do just that, right? Cool! Maybe I will finally get less frames skipped!

Someone mentioned line skipping. Would it be possible to take use just the center of the sensor to avoid line skipping? Just like GH2 does in EX. Tele Conv. mode ?

so.. 550d seems to be useless for raw, because in order to compare it to a hacked Lumix GH2 it needs to record at least in the same resolution.

3 Record with 2x scope at 12 FPS, tested with 1360 x 694 for 2.35 and 1440 x 694 for 2.48
Stretch 1360 x 694 to 1632 x 694 (2.35) and 1440 x 694 to 1728 x 694 (2.48)

I did not get that.. what do you mean?

Could it be that in 720p mode the captured area is actually smaller? That would explain the higher amount of frames. The picture I get in 720p mode is much grainier and noisier than in 1080p mode.

mm, dunno, looks quite grainy to my eyes. Perhaps needs higher bit rate export before uploading to youtube?

Managed to squeeze out 30 frames of 720p @ 23fps

http://vimeo.com/67151500

406p @ 23fps (720x406) seems to be stable for me

http://vimeo.com/67151498

It seems like there's a spike in nessecary transfer rate right at the start which kills it for some of the higher resolutions. I wonder if there's a way to solve this?

I noticed that too

Looks like my Toshiba SD card is not stable, because sometimes I am able to capture quite a few frames in 960x408 @ 24fps, and next time it stops  immediately even at lower resolutions.

Here's my quick test http://vimeo.com/67112590

My workflow on Mac:

1) raw2dng
2) batch convert in RPP > tiff (16-bit L Perceptual)
3) Terminal : ffmpeg -f image2 -r 24 -i %6d.tiff -vcodec libx264 -preset veryslow -qp 0 -pix_fmt yuv420p movie.mkv

Think I will play with Automator to make a script which will automate the whole process. As you can see the clip is very short, because it stops as soon as 1 frame drops.. I can allow skipped frames, then it drops a frame or two occasionally..

EDIT: Forgot to mention that I also adjust color and exposure in RPP and save setting as directory default before loading all dng's

Do you have global draw off etc?

Yes, I turn everything off

I used this build: http://www.magiclantern.fm/forum/index.php?topic=5582.msg40579#msg40579

Auto ETTR Build. I have a 45mb/s Sandisk Extreme card.

Hmm, I am using the same build, but my card is Toshiba 60mb/s. I should get another card..
