Raw Video / Re: 50D - 14bit raw video builds and test results

« on: July 27, 2013, 09:55:31 AM »

I have been spending a lot of time in the 550d thread because thats the camera I have. The 50d isn't that much more money then the  550d but the results for shooting raw seem dramatically better yeah?

I'd say that the 50d is the best bang for your buck raw video camera going.

What do you think?

The 5d m2 isn't getting much better results then the 50d is it?

Obviously the 5d m3 is the best but WAY more expensive too.

Raw Video Postprocessing / Re: RAW conversion for Davinci Resolve

« on: July 01, 2013, 04:37:11 AM »

I use rawmagic. Then once the CinemaDNG files are in resolve, I change the raw settings for CinemaDNG files to BMD with highlight recovery. Gives a nice flat image and appears to keep all the highlight detail quite well.

When you bring your cDng's in resolve do you see hot pink highlights?

I only see the hot pink in resolve. So it seems like resolve needs resolving.

I really new to resolve and only have the Lite version. Maybe I need to change some settings in resolve to get rid of the pink?

thanks

I asked the crw2dpx dev if he could add dng support. Looks promising.

I tried Photomatix, not sure how this would work for batch processing dng to exr.

Have you tried this?

Looks like it can only export to tiff or jpg?

Thanks

I'm trying to convert a .RAW or .dng file to exr on mac.

I've found this info so far. Shows how to use dcraw in the terminal to convert raw files to other formats.

http://the-fuji-x100.blogspot.com/2011/03/compiling-and-using-dcraw-for-mac-os-x.html

I got stuck at opening up my raw file I got an error in my terminal.

Code: [Select]

any ideas?

Thanks

Hi, so why my final RAW VIDEO in canon t2i appear very cropped ? and this can be for my sd card speed? i use a "transcend sdhc class 10 32gb", i put the config: 640x360px but i cant get 1280x720px with no cropping, so what i need to have the exactly view i have in my viewport? Thanks, help!

This happened to me as well the first time. I couldn't figure out why things are so cropped then I saw the crop marks and I realized it's how we can shoot raw by making it cropped.

Come on guys give them a break it's not like there's a manual for the stuff.

To be honest , I also thought, that the more buffers are better, even if the overall size isn't bigger, I don't know why I haven't tried so far: D, but here it is:

Some really quick test results here, on 550D with SanDisk ExtremePro 16GB, 1280x426 @ 24fps:

Sorting	Buffers	Frames	Seconds
asc	8Mb+31Mb+31Mb	317	~13
desc	16Mb+16Mb+15Mb+15Mb+8Mb	1326	~55
asc	8Mb+15Mb+15Mb+16Mb+16Mb	1395	~58
none	15Mb+15Mb+16Mb+16Mb+8Mb	1326	~55

Try and let me know:

Great findings by the way a1ex, I'm still experimenting with this, and with your speedsym.py script.. looks like it worth the try thanks!



EDIT (9 x 8Mb):

Sorting	Buffers	Frames	Seconds
-	8Mb+8Mb+8Mb+8Mb+8Mb+8Mb+8Mb+8Mb+8Mb	1565	~65

With this new xaint I get twice the number of frames!

8Mb+15Mb+15Mb+16Mb+16Mb

was getting:

80 frames at 1152x460 with 23.976 fps with my Kingston sd card which is the same speed as the sandisk 45 mb/s.

now getting

162 frames at 1152x460 with 23.976 fps with my Kingston sd card which is the same speed as the sandisk 45 mb/s.

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.

I get 80 frames at 1152x460 with 23.976 fps with my Kingston sd card which is the same speed as the sandisk 45 mb/s.

You are getting like tens times the frames I am with the extreme pro.

Here are some other posts Re: EXR workflows.

With the cinema DNG converter getting close I think going into resolve and exporting it exr will be the best workflow.

or when NUKEPEDIA gets up and running and we can get the J_OP plug-in To import DNG sequences into nuke

it doesn't matter if you use ducati editions* on 550D, it can handle only 20MB/s data output to the SD card, I'm using both Sandisk extreme 20MB/s & 30MB/s (old series) and new Sandisk extreme 45MB/s there is no difference on bitrate increase / decrease.

here is the test of Sandisk extreme 30 and 45MB/s at USB 3.0 card reader on my site.

http://hepsicekiyor.wordpress.com/2013/05/12/sandisk-extreme-45mbs-hafiza-karti-inceleme/

*they are old, but if they were new, I know they can kick 120MB/s today.

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.

@notdabod
i used a sandisk extreme pro 95 mb/s 32gb to get 240 Frames at 1280x426...

thanks for the post.

sandisk extreme is 45 mb/s
sandisk extreme PRO is 95 mb/s


I'm wondering how big a difference a sandisk extreme vs extreme pro would make?

anyone done any tests?

It's just that costco has a sale on extreme's not extreme pro's.

thanks

Tried both 30mb & 45 mb ExtremePro cards and 45 gave me more frames and fps.  I've landed on 3:1 1280x426 @ 23fps, after maybe one drop frame record, it'll give me 3000+ on the 45MB... fyi  Magic Raw record module...

those are great numbers!

Wow the 550D is a real raw camera!

Hey guys here are two tests of the ML Raw Module:

from last week in Istanbul 960x480@24fps upscaled to 720p (ML_960x480_Raw_Rec from mk11174). Please download the HD Version (vimeo hd limit is reached)

and from Rhein in Duesseldorf 1280x426@24fps (latest built) got 240 frames continuously.

Thank you guys for your excellent work on 550D.

Wow 1280x426@24fps (latest built) got 240 frames continuously!

What sd card do you have, if I may ask?

I started shooting raw yesterday on my t2i. Wow it's a new camera!

I'm a raw shootist for life. No going back.

I am only getting 70 frames at a time at 960-544, but still it's shockingly better then 1920-1080 smashed by h.264.

Thanks so much for everyone's hard work to make this happen.

full-what? full-hd? yeah its impossible with 14bit raw at 20MB/s record rate.

we're already capturing 24fps 960x320px RAW Video on 550D, an it up-scales easily to 720p.

WOW!

Would you please share your steps to getting RAW working on 550D?

I think we can assume that everyone has the last firmware from canon and ML, but what next?

I did get RAW working on my friends 5dM2, is it as simple as that?

Just drag and drop the right files from the link below on the SD card and reformat?

Raw Video Postprocessing / Re: Offline/Online Workflow for DNG in OS X

« on: May 28, 2013, 02:17:42 AM »

Is anyone here good at writing shell scripts?

I've been experimenting with a script that takes a folder of DNG files and converts them to JPG. It uses the white balance of the DNG file and doesn't do any other adjustments (focus here is on speed). It's running dcraw to generate a standard output and then piping that to cjpeg from the old Netbpm toolkit.

Right now using this method, I'm processing about 111 DNG files in a minute, versus the ~70 I was getting in Photoshop/ACR.

But the best part is, I can run multiple instances of the script (it's really a matter of how many processor cores you have), so on my 8-core MacPro I stopped at 6 to leave a little overhead for other stuff.

The rates stayed more or less consistent with that many processes running, I think the lowest dip I saw was 105 images/minute, so obviously this is way better than just running it one at a time. That's a rate of ~630 frames/minute, or about 9x what I was getting doing the same thing in ACR. If I raised that to 7 or 8 instances it could probably hit 50% of realtime. Granted these are just proxies, but that sounds good to me!

Now the big question - can someone with script experience tell me if this is easily implementable:

1) Launching multiple instances within the script, either on the same folder/shot, or multiple folders/shots

2) Running the script recursively, so that I can give it a base folder and have it process everything (including additional folders) within that

I'm not a programmer, so I'm mostly fumbling around at this. The script is extremely basic right now:

Code: [Select]

#!/bin/bash

mkdir ./output/

for i in *.dng; do dcraw -c -w ${i} | cjpeg > ./output/${i}.jpg

done
Right now that makes an /output/ folder with the JPG files, although they have the extension .dng.jpg which I've been batch renaming in a separate step. I'm sure that can be scripted too.

Anyone want to help out?

Wow nice work!

can dcraw export to exr files instead of dng?

I read something somewhere that you could.

Thanks
