Just curious...for those with the 5DM3, wouldn't it make sense to put the firmware on the SD chip and leave the CF clean for video? I can however understand if you don't have an option, then you are stuck.

@ajay and @audionut: can you develop your test shots (the same pictures that you posted earlier) with latest cr2hdr?

A1ex ... I took the two images that I sampled before using the latest cr2hdr and the halo effect is completely gone from the orange. The second image still has moire caused by the feathers, but the false colors are reduced quite a bit. Definitely better with both images.

Yes, some samples will be useful.

a1ex...Here are some 100% cropped images showing the artifacts. The first image shows extensive moire in the feather detail:



The second image shows the color halo effect. (Close-up of an orange.) This reminded me of the halo problem that Canon corrected when both the 5DM2 and 5DM3 were first introduced. It usually reared its ugly head with night-astro shots of stars or xmas lights at night:



If you want the originals, let me know where I can upload them.

Thanks again for all your hard work. --AJ

Thank again for another brilliant addition to the firmware for the 5DM3. I did some extensive still-shooting with the mod this morning...the dynamic improvement is incredible -- well done!

Just a few comments using the cr2hdr program (These are not complaints/criticisms, just letting you know what I experienced.):

1. Moire is extensive with bird feathers.
2. I'm seeing color artifacts around small, over-exposed areas. (By small, I mean points that are maybe 10 x 10 pixels or less.)

If anyone wants to see samples, let me know.

Raw Video / Re: Uncompressed 14-bit RAW video testing - 5D Mark III
« on: June 13, 2013, 05:25:48 AM »
Please forgive me if this was already mentioned, but at least the June 9th build and previous builds have a bug that you may or may not be aware of: When I delete a file in the file browser, I immediately lose the audio on my headset. To revive the headset audio, I must move the record video switch to live view, then back to record video mode. It's not a show-stopper, but it can be rather annoying.

You guys are GREAT!

Is it possible to add a feature to format cards in-camera using exFAT? (I've been formatting my cards this way in the pc to remove the 4GB file limitation.)

Thanks again for all that you guys have accomplished!

Here's a short clip taken with the 5DM3 and Canon's 600mm f/4 II lens. Works great by recording audio on the SD chip and the video on the compact flash. I've been getting full 1080p using Transcend's 1000x 32 GB chip.

Enjoy!

HI! Is it a 1000x card and have you tried it on 24p at 1080p? I,m about to buy one but it doesn,t seem to work that good?

I have been using (2) 1000x 32GB Transcend cards and it will work solid 1080p 24fps. That's with everything disabled (no global draw). Also, if I go into crop mode I have to scale down to 1920 x 840 in order for it not to skip frames. Does anyone know if the Lexar can do full 1080p @ 3x?

Thanks,

AJ

I've added live preview in 5x mode, so you can see exactly what you are recording. Just wait for next build.

Thanks Alex. I don't know if you realize this, but you guys are making A LOT of frustrated Canon users very happy.  :)

Another RAW video, but from a perspective as a bird photographer/videoagrapher. I was quite anxious to see how the 5DM3's RAW output would look using birds as a model. Here's a pair of Eastern Bluebirds preening. I filmed in 1920x840 perspective due to bandwidth limitations when using 5x zoom using Trancend's 1000x 32GB card. I have gotten it to work reliably now at 1920 x 1080 but only at 1x not 5x. 5x drops frames @ 1080p.

Also...I have no idea if I am correctly using the 5x mode. I set zoom to 5x, then record through ML's menu. Is this correct? I found that in 5x mode, what I see on the LCD screen is not what is being recorded. The subject that I want centered is usually off to the right or left of the zoomed display. (That's why in 5x mode in this video, the birds are chopped off frame. This test was really to see how the resolution looked at 5x.)

Anyhow...I am so elated to finally get excellent quality video from the 5DM3. I can't thank you guys enough for doing this. I will make a donation today!

Here's the clip...I did color correction and a bit of sharpening to the DNG's.


Thank you ML team!

Can someone please set me straight....I have been trying to get 1:1 cropping while recording RAW and I have scoured everywhere trying to figure out how to do this so I don't have to bug people, but I cannot for the life of me figure out how to record RAW in anything other than full-frame. What do I need to do to crop/pan while recording?

Sorry to be a bother...

Yoshiyuki,

I'm not seeing those options (1880 x 1080 or 1880x1152). Is there something I need to set? I also have no idea how to use crop mode. Can you explain?

As far as 1920 x 1080, it states I need 82.9 MB/s and it works for a limited time and eventually stops or skips frames. 1920 x 960 now works w/o issues.

Thanks,

AJ

Interesting. So it can do 86 MB/s, but still can't quite do full 1080p? What does the raw recorder say when you set it that high? For the 5D2, it says it needs 81.2 MB/s for 1880x1080 and 86.6 MB/s for 1880x1152.

For those who are interested in the performance of the Transcend 32GB, 1000x. I reran the test with global draw off and in liveview:

Try turning global draw off, that should release a little more memory for 1920 x 1080 recording.

I have the same card and it fluctuates between 80-84MB/s recording 1920 x 1080.

Funny you should mention that, cuz I just did that and it did help a bit. I also turned off audio...not sure if it matters, but I turned off just about everything I could think of. I can now get 1920 x 960 to work reliably although 1920 x 1080 still skips frames intermittently. Sometimes I can go pretty far w/o skips.

Thanks,

AJ

Here are test results of the Transcend 1000x 32 GB on the 5DM3:



In practice I have found 1920 x 840 seems to work flawlessly, greater than that eventually skips frames.

Is this on the mark III? Cause I am expecting 2 of these tomorrow and that will be disappointing! Can you upload footage/benchmark for your tests with the Transcend 32gb 1000x?

I'm about to run out the door, maybe later I can post a benchmark, but yes, that's on the Mark III.

Can someone answer my question regarding cropping? Is is possible to crop and only use the center pixels? Or some other smaller width than the actual sensor for 1920 x 1080? That's what I was hoping for...similar to the Panasonic GH2/GH3.

Thanks,

AJ

Please excuse my ignorance here, but I keep hearing about the ability to crop/pan the sensor. I have not been able to figure out how to do this.

FYI...Transcend's 32GB, 1000x card works fine up to but not including 1920 x 1080. At 1920 x 1080, it does drop frames intermittently.

Thanks for any help.

Tried some tests this morning with the 5DM3. I am noticing vertical banding in blurred backgrounds. They appear on the dng files. Anyone else seeing this?
