I can't reproduce any LV updating or freezing issues.

Memory is allocated only while recording, and it's deallocated right away.

Thanks Alex. I tested the mentioned bugs and it is all cleared now.

Thoughts on 5D3 new compile commit: 1112eed

One more thing, I want to used cropped digital video mode extensively for wildlife applications where the extra reach is an absolute must as well as exposure adjustment to changing conditions. For these situations I would love to have the auto exposure in zoomed mode. I tested the new build and it works perfect for non cropped mode but the auto adjustment does not work when zoom, so if I pan to different area the exposure does not change. I noticed that if I press half shutter the exposure corrects while I hold half shutter so maybe it is possible to enable this feature in zoom mode.

The Hack3D now showed REPEATABLE modest improvements in all video frames tested with slower 60MB/s Sandisk card. The test with the Lexar 1000X card also showed REPEATABLE improvement. The performance without the hack of the Lexar 1000X seems a bit better but not REPEATABLE sometimes better sometimes equal.

Thanks for listening, I will help on testing as much as possible.

Auto exposure works just like with plain Canon firmware. Maybe try in photo mode with expsim off?

Or, try enabling FEATURE_LV_ZOOM_AUTO_EXPOSURE in features.h. It seems to cause some trouble, but I'm not 100% sure.

RenatoPhoto · « **Reply #78 on:** May 20, 2013, 09:10:41 PM »

I changed features.h for 5D3 line 21 form undef to define. I then compiled this but did not enable auto exposure in zoom mode.

Ok, now I turned to Photo Mode with expsim OFF and it WORKS. I will test this feature and report back.
Thanks for the help

a1ex,

What are high priority items at this stage of development? Is it file spanning? Is it audio? Just wondering.
Thanks.

a1ex · « **Reply #81 on:** May 20, 2013, 09:42:22 PM »

I'd say making it rock-solid and enabling the module support in official nightly builds. Lots of fine-tuning and bug-fixing.

I don't see this as something for recording long conferences, and you already have basic audio.

Reporting back: auto exposure in zoom mode works without a flaw. No black frames or any troubles. With this feature enabled I can concentrate on focusing and leaving the exposure in Auto. For fast moving action I cannot adjust everything at the same time so this definitely helps.

Build "006d890" - Works great but I saw a fix related to DaVinci Resolve (removing thumbnails - "89e62d8 ") and I wanted to report that it's not working. Resolve still sees the files as 128x96 and doesn't interpret them right. ACR or PS doesn't recognize the camera id either, which was another fix in the code if I remember right. Magenta cast is definitely fixed though it didn't saved (or read) the WB I set on camera.

I was trying to figure out how to make the .DNGs fit the Cinema DNG standard, which is the only thing Resolve reads (allegedly a DNG 1.1 Subset), and I ran into the white paper from Adobe. I'm sure you're already familiar with that document but you have the link below.

Is there somebody who can record raw 5x zoom on CF Transend 600 32GB? I have memory error

a1ex · « **Reply #85 on:** May 21, 2013, 08:29:58 AM »

What exact error? You don't get memory errors when the card is slow...

vstrglv · « **Reply #86 on:** May 21, 2013, 08:35:40 AM »

"Memory error MB" for very short time. Very difficult to read. In normal mode I can record raw 1920x1080 with small number drop frames. I have 2 samples of CF Transend 600 32GB. The same result.

a1ex · « **Reply #87 on:** May 21, 2013, 08:47:58 AM »

Got it. Can you chek in Debug menu how much memory you have?

vstrglv · « **Reply #88 on:** May 21, 2013, 09:22:18 AM »

Ok, 10 hours later.

Thank you, a1ex. A quick question for you. Has there been a fix for 5x framing issue yet?

a1ex · « **Reply #90 on:** May 21, 2013, 06:13:22 PM »

Huh? it's working well here...

stevefal · « **Reply #91 on:** May 21, 2013, 06:27:38 PM »

5X doesn't work for me - "Memory error MB"

running 006d890 on 5D3 + Lexar 64GB 1000X

Debug menu Free Memory: 162K + 3720K

[EDIT] 5X working for me now on 240050c.

a1ex, when I use 5x, it always capture what is left to the frame on LCD.

Never mind. I just read I had to move the focus square 17 ticks to the left. It works good now.

That is the way it is, that mode is refereed to Cropped Digital Video. Please read the manual here:

17 times to the left and 8 to the top. Got it. By the way, this feature is fantastic to have!

For most uses I find that the setting obtained in Prefs Tab by:

3. Scroll to Focus box settings, press Q button, and enable Snap points choosing the Center/TL/TR/BR/BL setting. Press Set button and Q button.

To use this setting (in LV) just press the joystick and the focusing box will just move to the correct area. It goes Top Left, the if you press it again it will go, Top right, etc It is a quick way to get there, a shortcut.

Hurray for ML! I love this specific feature since I use it for wildlife video. My 300 f/4 lens is equivalent to having a 900mm f/4 (it does not even exist)

After Raw Video enabled and after raw video recording in full screen (1920x1080):
Free memory 162k+3720K
Image Buffers 720x480,1904x1274

After raw video attempt to record in 5x zoom following "Memory error MB"(1920x1080):
