Uncompressed 14-bit RAW video testing - 5D Mark III
« on: May 17, 2013, 04:59:17 PM »
I just wanted to create a topic that is specific to testing 5D3 nightly builds.

1. 5D Mark III only
2. 14bit Raw - no compression suggestions/ideas please.
3. This thread is to test 5d3 nightly builds and report back the results/findings.
4. Even ideas/suggestions should be limited to the development of ML builds of 5D3 14bit raw video.

Nothing against other camera users and other innovative ideas. I thought it would be good to have a thread that someone like me can check from time to time to read what pertains to 5D3 14bit raw ML instead of reading through many pages about other topics.

Admin, if you feel this thread is redundant and unnecessary, you can close it.

I was thinking the same thing.  It is a very good idea for my purpose but who knows it it works for DEVs.  If Ok there should be other threads for other cams to be more organized.

I will start with Audio wav file test

By importing the dng frames and wav to video software (Vegas Pro 12) file I obtain a synchronized video.  It seem ok!

The only issue I have is that the (apparent) audio file length is very large so the video software imports it as 12 hours 25 minutes and 39 seconds long.  If I play the file in WMP it play fine but again the length is incorrect and the file repeats itself over and over for the full apparent length.

Zoom Mode:

In first builds I pressed the zoom button and obtained a clear colored zoomed image in LV.

Now I get 5X gray image and distorted for an instant.  This goes away during recording RAW video but comes back it I stop the video.
In 10X the image is OK.

60 FPS frame distortion.

By using RAW video while the camera is in Video Mode I can select a video mode of 1280x720 60fps video.  If I press the record button the camera records RAW video at 60 fps but.. The frames are distorted (shrunk heigth) and need to be stretched in post to maintain the image shape.

ADOBE CAMERA RAW opens the DNG file which always have White Balance set at 6050 and Tint at +77.  This can be corrected in post but.. can this be set in camera to something more neutral like WB=5700 and Tint +6.

5/16th build seems to faster than 5/17 version. Anyone else agree?

When using the 5X zoom the gray screen now has framing white-line box which helps frame the subject.  This is very hepful but... when I press the record button the focusing box resets to the center so the framing and the subject are lost.  This framing needs to be maintained during recording also.

The same feature is needed at 10x.

Better solution would be if the video crop area could be changed to the center of the sensor where the lens is also at its optimum resolution.

For now I just use the joystick to control the focusing box by pushing it to the left seventeen times and eight times toward the top to obtain the correct framing.  This focusing box always remains in this position which is very helpful for framing 5X or using 10x for focusing.

Negative, I experienced the same speed.   The 5/17 version must include g3gOO commits to fix some errors in earlier changes.  May want to get a different build.

This uses quite a lot of CPU power. I'll try to slow it down though.

In 10X the image is OK.

I've found that the image will be distorted if your in 5x mode when enabling RAW record.  If I make sure I'm not in any zoom modes when enabling RAW record it works fine.

What's better - distorted and full screen, or correct aspect ratio, but tiny image?

Personally I'd prefer to have the correct aspect ratio.  A menu option would be best, but that's just being a typical user asking for lots  :P

Full screen, if its bigger than aspect ratio I can even tilt or pan in post.... David Fincher style.

I would stick with CORRECT aspect ratio.

I don't care if it's a bit distorted, I use it for focussing not admiring myself in a mirror. I've been shooting 1.5x anamorphic for years, it's never been an issue. How is it gonna be any good for focussing if it's tiny? But at the end of the day I'll take whatever I can get, thanks mate.

For focusing, you have the 10x mode unchanged. For framing, use 5x. For framing with high-res, press the shutter halfway.

I've just changed it for 1:1 aspect ratio (both preview and playback).

60 FPS frame distortion.

By using RAW video while the camera is in Video Mode I can select a video mode of 1280x720 60fps video.  If I press the record button the camera records RAW video at 60 fps but.. The frames are distorted (shrunk heigth) and need to be stretched in post to maintain the image shape.

For 600D it is 166% - you need to upscale height to 166% with 600D to restore correct aspect.
Can you calculate actual distortion? Knowing it, we can control output resolution.
(with 166% for example and 1920x650 60p it is 1920x1080 60p after correcting aspect in post. pretty nice)

That must be it. Just redownloaded 5/17 build.

5x doesn't display in grey. back to 1:1
Using KOMPUTERBAY 128GB CF 1000X, it constantly skipped frames at 1920x720 until I tried CF card workaround on. It recorded all the way to 4GB. (audio disabled. focus peaking on)

Testing of New Commit May 18th.

1. First thing I lost some focusing points.  I have always been using the left focusing points (20) and now I only have (9).  it kind of looks like the focusing system of the 5D2!  I cleared config file but nothing, changed ML versions and nothing.  When I press M-Fn to flip through the available selections I am still missing some of the points.  I use to have 61 points, and now I only have 33. The center seems correct.  On the right I had twenty points and I only have 9, same on the left.

Sorry this was operator error.  I changed to canon 180mm macro lenses which do not support all the focusing points!  Focusing points are back to normal.

Testing of New Commit May 18th 5D3

2.  The framing for 5X and 10X is still giving me a headache.  The 5X frames correctly but if I want to focus at 10X the framing goes to the center so I cannot focus on the subject.  Focusing is more difficult without colors, the jerky LV view is disturbing.

If this method of automatic framing does not work i would suggest the following system which worked fantastically for me:

As I have mentioned before I could do correct manual framing by moving the focusing square with joystick seventeen times to the left and eight to the top.  Now I found out that this can be simplified by using in Prefs tab the "focus box settings" menu and selecting the option "snap points" and selecting "Center/TL/TR/BR/BL".  Now when you press the joystick the focus box moves and when you get it on the top left then stop and it is almost perfect for zoom framing of RAW video.

I further tested this method with the commit of May 15 which does not have the auto framing and WORKS BEAUTIFULLY.  I can zoom 5X, 10X with proper framing and no gray boxes or fuzzy lines.  I can even record in Zoom mode and move around following the subject and refocusing by pressing half shutter.  I can go 5X, 10X, or full view without any problems in full color and resolution.

The snap points option could include a simple 5X snap so that you can flip from center focus or 5X focus at the tap of the joystick depending what type of video you are doing.

This is the ML version that works best with "snap points"

3. Tested new Hack3D but did notice any buffer speed improvement.
Under some test I got more frames after turning Hack3D OFF

4. If you press zoom button while recording to focus on different subject camera stops recording.  In some test I had pull battery out.

Again this does not happen with May 15th build

A question regarding the smaller sizes (1280x720 for example). On the latest build I installed it's now doing a crop of the fullframe sensor.
Am I remembering something wrongly but imho on the last build from some days ago it was recording fullscreen and scaling on that resolution? Or was it always this way?

2. I don't know exactly where the 5x cropped frame is, and this is camera-specific. The 17-click trick will not work on 5D2, for example. Use 5x for framing and 10x for focusing - the 10x box can be moved around.

3. try 720p, or compare the write speeds.

4. it's a safety feature, it never worked correctly.
