That is working with my newly bought 650D flawlessly! Fantastic! Thanks!

Can someone tell me - how can I use raw2dng chroma smoothing somehow together with dual iso?
I've been so long out of forums, and so many info & tools out there... But they all seem not exactly what's needed...

That's all great. The only downside I see is the image sensor size...

They all say that Super35 is film-industry standard, blah-blah... - Yes!...

BUT!

Industry is using Anamorphic optics with 2x anamorph coefficient. Making this Super35 TWICE as wide optically.
e.g. Cinemascope is 21.95mm wide, but after anamorph it "gets" - 43.9mm!
And that's even wider than 5dmk3.

Of course you can use $50K industry-standard anamorphic optics, but... why not just use RED or ALEXA then?
But if you can't afford true anamorph, and you're just low-budget DIY indie filmmaker - then you need a LARGE sensor with spherical optics, and crop it.

That's what I think... It needs to be going large!
But I hope it will.. In the next commercial release.

Well, it still hangs. With Review Hold, without hold (Off), with 2sec hold. It just draws a dozen of dots and then becomes unresponsive. It hanged with LED on, hanged with LED off.
I used 600D may 08 nightly, then cleared the card and installed clean may 13 - same thing. Btw, 600D has all builds Failed starting from May 13.

Here's the vid:

And here's what's in PPMs:


Btw, I also get this SNR curve (noice profile) table overlay slightly blinking in every menu (including canons own) and LV - even after restart with battery out.

Do I have to use a tripod? Found it - yes.

How long should it take to sample data? Mine's already working a couple of minutes - maybe it halted?
(600D)

Well, tried it for a couple of times. One time it always said "RAW Error", second time it halted again.

Today's nightly for 600D doesn't work (Built on: 2014-05-03 04:00:36 +0300)

Camera LED just blinks and nothing happens on screen or whatever, it even blinks after turning camera on and opening both doors - still blinking.

05-02 works though.

Anyone else trying Dual Iso video on the 600D?

Where can I get the build with Dual Iso? TragicLatern has only july SixThirty download.

Dual Iso is now available for 600D, the link was in the dual iso thread but it's dead now. Soon as it's back up I'll update the first post of this thread with the link.

Could you please tell more about this? I've searched the last few pages of dual-iso thread, but can't find much info about 600D. What's available? Only photo, or video too? What are the drawbacks (there must be some because 600D isn't as good as 5dmk3, right?), etc...

Maybe it's sharper that usual, but... still looks 720p. You can judge this from the logo in the end, which is supersharp (compared to the footage).

Do you plan returning all the GOP/Slice parameters to some newest build?

bit-depth has nothing to do with bit-rate

I found adtg shutters:

Could someone tell please what does it mean? I googled the forum and wiki, and only found out that these are some registers, that help with FPS Override... But what exactly should we test practically?

Heh, installing all and everything from Devel in Cygwin (4Gb!) - did the trick

But anyway, it's interesting to know which cygwin module was required...

Thanks! But what do you recommend to build it under windows?

There seems to be a problem with 'fseeko':

Cygwin gives me this:

$ make raw2dng
[ GCC      ]   raw2dng
[ GCC      ]   raw2dng
raw2dng.c: In function 'main':
raw2dng.c:60:5: warning: implicit declaration of function 'fseeko' [-Wimplicit-function-declaration]
[ GCC      ]   raw2dng
raw2dng.o:raw2dng.c:(.text.startup+0x58): undefined reference to `fseeko'
collect2: ld returned 1 exit status
Makefile:14: recipe for target `raw2dng' failed
make: *** [raw2dng] Error 1

MINGW this:

$ make raw2dng
[ GCC      ]   raw2dng
[ GCC      ]   raw2dng
raw2dng.c: In function 'main':
raw2dng.c:60:5: warning: implicit declaration of function 'fseeko' [-Wimplicit-function-declaration]

raw2dng.o:raw2dng.c:(.text.startup+0x58): undefined reference to `fseeko'
collect2: ld returned 1 exit status
make: *** [raw2dng] Error 1

Google tells me that MinGW doesn't support big files (http://stackoverflow.com/questions/9026896/get-large-file-size-in-c)

What should I use to get it right?

[raw2dng.c]

How can I compile raw2dng.c?

Already downloaded cygwin, but makefiles under modules don't do anything, and raw2dng.c requires raw.h and chdk-dng.h

Getting Err 70 almost every time I use MagicZoom. Updated the ML nightly build to latest, with SixThirty, but same problem.

I think it's time to put a little FAQ in the first post...

Hey at that moment i don't have the chance to test it myself so i want to ask you, what is the highest possible resolution you can shoot raw at lest 3-4 seconds (i'm NOT interested with continious) at 23.976 (24 fps) ?

I can get 100 frames (4 seconds with a bit) at 1600x672 (2.39:1) @ 23.976 fps (in 640x480 canon mode).

Or I can get around 120 frames (5 seconds) at 1728x576 => 1728x960 (16:9) @ 23.976 fps (in 720p canon mode, with skipped lines, stretched mode)

So, if you just need a couple of secs - you can already shoot at almost full-res.

Wow great. Now I can shoot reasonable time on max resolution @ 2.39:1 (1728x...).
Around 150-250 frames is usually enough. Both in [email protected] mode, and in 640@12fps mode.

By 720p I meant the canon mode that uses lineskipping.

By youtube 480p I meant the difference in sharpness between normal mode and line-skipping mode. And it's obvious that the RAW gives better color controls.

This time I have to request something like this, now that I got my hand on a t4i, and I want to see how far can it go.

Well, I've made some test yesterday, with 24fps 720p and with 12fps 640x480. Yes, sure, 12fps gives you a very decent picture quality. See for example here: http://www.naumik.com/temp/scr4/20130617-vnc-280kb.jpg

But when you have something to move fairy quickly on a textured background - you'll get this:
http://www.naumik.com/temp/scr4/20130617-gj8-256kb.jpg

I know twixtor has solutions for this with manual masking, etc, etc... but it's a too hard workflow already...

And it's not too visible on playback (just looks like blurred edges around moving things).

I've didn't develop all my yesterday's tests, so maybe I'll post an update later today or tomorrow.

But overall I think it's good to shoot slow moving scenes with 12fps, and fast moving thing with 24fps 720p mode.

I tried to shoot my usual style (short scenes, 5-10-15 sec per take), so I've got 1664x704 with 12fps, and 1536x384 (stretched to 1536x640) in 720p mode 24fps. Fairly good as for me.

Here's the difference between these modes:
12fps 1664x704: http://www.naumik.com/temp/scr4/20130617-s49-384kb.jpg
24fps 1536x384: http://www.naumik.com/temp/scr4/20130617-c32-321kb.jpg

Both stretched to 1920px wide using PhotoZoom Pro.

My opinion is - after YouTube applies it's magical compression to it - no one will see the difference (especially if watching from Facebook in 480p mode in little window).

So what? No one tried RAW on 650D?
Youtube has a lot of sample raw videos, and here I can't find any, even can't find an official 650D raw thread (except this one)...

Yeah, anamorph is great, sure.

But to me - it's unreal. Firstly the price, then focusing trouble (two focuses instead of one) so need an assistant (or two), and lens limitations/mounting trouble.

I have one. Zoom H2N. how do I sync ?

How the big guys do - with a clap.

Btw, people, please understand:

Say you want to shot 50mm (on 5D fullframe, normal lens, real 50mm, pretty standard and close to human fov)

To get the same FOV, you will need a 17mm lens when shooting RAW 960x540 16:9 on 600D (because of 2.88x crop factor (1.8*1.6))
And if you also use 3x crop, or zoom, or something - you'll need a 8mm fisheye, or even wider to get an ordinary normal 50mm field of view.

So now all talks about best quality 960x540 stretched to 1080p on youtube fit more to shooting the moon in the sky, birds in the forest and girl in the window next block - very special purpose, not for everyday shooting.
With all these crops, zooms, cropped raw little windows - you're getting a really-really-really long lens which isn't quite suitable for ordinary shooting (especially interior shooting). And if you cut it to cinemascope 2.39:1 - then you get even less space and less fov.
If you like to shoot long-lenses - then 600D is for you. If you're more to shooting wide - then nope.

Although, I can get a full 1728x960 (stretched from 1728x576 sqeeze in 720p mode) at 12FPS continuous recording (19.9MB/s stream) - and that's good for slow-movement shooting.

And btw, if 650D has twice the bandwidth - then we can do 1728x960 stretched in 24FPS, correct? That would be best for me.

So what are our options regarding RAW shooting + sound recording ?

Buy a voice-recorder. Zoom or Tascam. 100-200$ on amazon.
