How can I post dng's here?
I can zip them and email it to you.

just put them in the public dropbox folder and post the url here with the "url" tags

Wow . . . wait a minute, Would I be too presumptuous to assume that if this works on the 5D2, this may very well work on the 50D!? Remember, the advantage of the 50D is that it takes CF cards - including the 1000x and has less overhead without audio . . .

Please say it will, Please say it will, Please say it will . . .

raw pictures work for 50D, I posted an example earlier in the thread, but burst pictures will need CONFIG_FULL_EXMEM_SUPPORT for 50D, which isn't yet available. I started adding support for 50D in raw.c but I've not found time to work out the correct offsets etc yet, hopefully I'll manage that in the next few days (or someone will beat me to it!).

For some reason my photos are 1880x1250 anyone know why?

I was able to get 54 DNG files in Jpeg mode on the 5DMK2 - Max I am able to get is 35 with Raw selected.

Canon 5dmk2 - duracell 600x CF card

I don't think any Canon engineers are following this thread. They know why

squig · « **Reply #204 on:** April 30, 2013, 03:21:50 PM »

So do you think Canon could enable 1920x752 RAW 24p recording even if you guys don't quite get there? It's just a matter of compressing the DNGs now isn't it?

I don't mean to sound pessimistic, I reckon you guys are gonna nail it.

Could we record video with 24fps, but only 2-3 seconds?

the current bottleneck for everything is sd/cf card technology, cards aren't fast enough yet

DjJuvan · « **Reply #207 on:** April 30, 2013, 04:45:45 PM »

What about using RAID technology on 5dmk3 with CF and SD at the same time? It could give some boost.

The only way out of the writing problem is to compress the frames to around 1MB. Canon doesn't need to follow the thread, they already made MJPEG on other cameras.

Just did a conversion to DNG Lossy using Adobe DNG Converter 7.4 and I got file size between 907k and 1136kb instead of 4965kb.

Good luck doing that in camera

1% · « **Reply #211 on:** April 30, 2013, 06:34:59 PM »

Can't make a module with TCC to do it or not enough processing power? Or maybe using the JPEG encoder? It should take both raw input and YUV since it does that for photos/eos utility preview.

*imo... that file size is enought to write continuously.

But could it be done in camera? Either to Lossy DNG or mjpeg. Do you think there is enough processing power?

not in real time at all

woodybrando · « **Reply #215 on:** April 30, 2013, 09:32:53 PM »

Seems like the only way it could work for more than a second is maybe if it can be subsampled from 14bit to 8bit and sent out the HDMI. are either of those things possible?

g3gg0 · « **Reply #216 on:** April 30, 2013, 09:45:08 PM »

short: nope, thats not possible.

but we implemented raw recording already.
see http://www.magiclantern.fm/forum/index.php?topic=5247.msg32533;topicseen#msg32533

its still experimental and not ready for release. but it will show you what is coming next.

One of the possibilities of RAW - you can get rid of most color moire with Lightroom!

N.Mendes · « **Reply #218 on:** April 30, 2013, 09:52:59 PM »

i'm not sure if that has been said before but, with the new 5d3 firmware (which allow an official hdmi output), did you try to record raw? With an atamos ninja let's say to an "SSD" ...

DjJuvan · « **Reply #219 on:** April 30, 2013, 09:57:31 PM »

You're saying as if there is Atomos Ninja2 laying in everyone homes.... get a grip Ok?

Some raw DNG tests:

g3gg0 · « **Reply #221 on:** April 30, 2013, 11:37:15 PM »

deshaker for virtualdub is very good when the video is shaky

wolf · « **Reply #222 on:** April 30, 2013, 11:43:45 PM »

Thanks for sharing.
At 29 sec (second subway shot) there is a change in exposure. Can you tell how this occurred?
And no more 99'er on wall street ;-)

1% · « **Reply #223 on:** May 01, 2013, 12:01:59 AM »

The expo change is from fps override. Yea.. I need to deshake (in ae or Vdub) and probably fix the black bars on some clips. Maybe I'll get longer ones from lverc now.

kgv5 · « **Reply #224 on:** May 01, 2013, 12:13:43 AM »

Could you please tell us what camera is it and what memory card did you use? Film is made of about 2 seconds clips so ~50 frames per each fragment am i right?
