Test 1 of HDR mode on 5D with Mosaic optical anti alias filter.

Used Nikon 50mm f 1.4, Cinestyle profile at 24P.

Showing 3 out 5 HDR modes 3EV,4EV & 5EV.

This is the first time I tried Magic lantern and this feature was the compelling reason to do so
and so far I find it very interesting indeed.

I think there is an issue with fast motion, (note the passing truck in window) I think this is aggravated by using 24P,
I will do human motion test next and will include 30P so there
will be more frames to interpolate.

Most impressive. We have done a lot of real estate videos in the South of France & the big bugbear was always that if you expose correctly for the interiors then the windows are blown out. Property videos look like a perfect application for this implementation of HDR as there isn't much movement when you are just panning over the furniture. Then instead of white windows we would have the beautiful blue skies.

Impressive indeed Nigel, also, since like you I do a lot of real estate videos as well.
This version of ML now gives your 5D adjustable FRAMERATES between 31-1.
Instead of just 30-24. So now you can have MORE incredible low light performance or timelapse and slow shutter blurring effects. (vehicles passing buildings, night shots etc.)

Also I must add since you mentioned real estate, that when you add the mosaic VAF-5D2 filter you also now have moire free and alias free buildings, shingles, bricks, cable lines, water etc.

The 5D has truly been on an extended life.

I have recently been using a Panasonic GH2 with 7-14mm F/4 lens for shooting real estate videos instead of the 5DII & been delighted at the moire & alias free footage that I get compared to a Canon DSLR.

The Mosaic VAF-5D2 filter is interesting but a little too pricey plus I love to use my Canon 16-35mm F/2.8L for interiors & apparently the quality drops off for lenses with a focal length of 24mm & below. I think that I can live with moire & aliasing if the HDR is as good as it looks.

Wow !
How hard was combining in Post?
Super interesting esp with the new Frame rates working on the 5D. I know they were concerned because of the larger sensor.
There also seems to be a new focus assist as well in Magic Lantern (not just the window) that shows you what is in focus, correct?
I am very interested in this feature as well.
Any idea when this is going to be released to more of the public,

Thanks Ted!!!

Sorry for the late reply John as I was busy doing some more tests.

Splitting and combining in post is a one click affair. The developers provided a command line script that automates the process.
This script and its corresponding softwares comes together with the 5D magic lantern+HDR beta
when you give a donation.

There is a ton of features that practically makes the 5D a different camera.

For focus aids there is peaking aside from the magic window, which gives a windowed enlargement
of the scene. -and it can stay on while recording.

For exposure, you have zebras, histogram and waveform.

You can plug in headphones for audio monitoring and control its volume.

Variable frame rates! other than 24-30 now you have 4-31.

4fps is useful for lowlight as this increases lowlight capability a lot.

The list goes on and on.

This is already being released albeit beta. But its working already.

Heres a 2nd test, this time shot in 30P, includes some human movement to test.

Thanks Ted,
Happy New Year
I didn't realize I could donate & download Unified and run it on a 5D.
I thought it was rewritten for the 5D. Or is there a direct link ?
The wiki is confusing
Thanks,

What's supposed to happen after you donate to gain access to the 5DII beta? I donated this morning and am wondering.

on the donation page there is now a link that says
something like "return to developer site" that will take you to a bitbucket page that says "Alex is sharing code with you" Download there.

I donated a little more in Euros (vs USD, in case that made a difference since it was a different Donate button). I didn't recall seeing it the first time.

I haven't loaded it on Camera yet...
But
is the HDR PC only @ this point?

John,
I believe I read in the developer's workflow forum that it also waorks on mac, even linux.

It's funny because I was wondering not to long ago I'd something like this is possible. Very happy to see this. I am in the process of upgrading from a 7d to a 5d right now and very much look forward to playing with this when I get a chance.

My question is this: Obviously there is some issue with fast motion. Is there a difference between 24p and 30p when it comes to fast motion? Could it be less of an issue if you shot at 30p?

Ted Ramasola
January 8th, 2012, 03:08 PM
Is this with regards to HDR video in 5D? If so then the answer is 30 would be better to use when shooting HDR due to the fact that your framerate would be halved in post then interpolated back.

30 would be 15 and 24 would be 12. So with 30 you would have better motion interpolation.

Though I must say the 60D or t3i would be better suited for HDR than the 5D since they can shoot 60P thus giving you a normal motion cadence of 30 after interpolation.

Brad Ballew
January 8th, 2012, 05:26 PM
Thanks for the reply. I wonder if using twixtor could help with some of the motion issues? I am getting a 5D this week so I will get a chance to play with it before too long. I was just looking through all the features of Magic Lanter and it's pretty impressive what they have done so far.

Ted Ramasola
January 8th, 2012, 05:35 PM
I am using twixtor now on my own workflow. I'll share it with you when I'm done.

However, do try to use the scripted workflow that the developers will give you if you donate for the 5D unified ML beta.

I'm using this "beta" version and it is already very functional.

The scripted workflow is a one click process and includeds 3 small apps/software that automates the splitting of the mov file, merging the 2 image streams then interpolating the footage back to the same length.

So far its acceptable for a lot of scenarios.

It it the workflow I used for the samples I posted.

Off topic, since you plan to get a 5D, -aren't you attracted to the new nikon D4? wink wink... ;)

Brad Ballew
January 8th, 2012, 09:45 PM
Look forward to it. There is a lot of potential in this. I hadn't read too much on the Nikon.. looks interesting. Out of my price range at the moment. Getting a great deal on a 5D and a couple of Canon L lenses.. so I can't pass that up. :)

Hey how exactly do you donate to get the beta of the New Magic Lantern?

Thanks Ted,

I donated and downloaded the beta. I should be receiving my 5D tomorrow. Will I need to download and install the current Magic Lantern firmware before installing the beta?

Ted Ramasola
January 9th, 2012, 01:54 PM
no brad, you dont need to install previous versions of ML. the beta can be installed on a 5D running the current canon firmware 2.1.1

Good luck on your new camera.

So Ted,

How do you separate the video into the two clips? It seems that the HD workflow that is included slows the clips down prior to rendering the frames. I thought I could import the A and B image sequences into after effects and slow them down with twixtor only to discover that it seems they are already slowed down.

Would love to hear some thoughts on your twixtor workflow.

Brad Ballew

So I am able to separate the different iso streams from the video. Came up with a real easy way to do it.

To blend them, I just put one on top of the other and dropped the top clips opacity to about 55%. Surely there is a better way of mixing them. Can I isolate the process in the workflow they provided to merge the two streams?

I actually had better results with my particular video using pixel motion in after effects than I did in twixtor. This method also allows me to shoot at 30 fps, split the streams, and then slow them down just the right amount to form them into one 24p video clip. This at least lets you decrease the amount you slow the clip down some.

Man, if the 5D could handle 60p at 1080.... This would one hell of a camera. Perhaps the 5D MKIII will?

The seq A and B are the separated streams. C is already combined and retimed as you might have discovered by now. Theyre ready to be imported to your NLE or AE for grading and post processing.

Yes, pixel motion after time stretch also works. However, changing opacities to blend the streams will not yield optimum results as compared to certain workflows/programs dedicated to handling HDR material.

Try PHOTOMATIX. use batch processing. Exoprt a seq of 16bit tiffs to grade in AE then retime it and use pixel motion.

Brad Ballew

Thanks Ted.. Actually having now played around more with the provided workflow, I have to say that it is pretty good. However, I think an alternative workflow could benefit certain clips. I am still getting a handle on Twixtor and am just now learning how mattes can help keep the motion from warping.

I think you could use the HDR with somewhat faster motion in the frame, run it through twixtor and use mattes to fix any portions that have warping.

I have to say that this HDR function is amazing.

One question I do have is this: Although I know that as of now, 60P cannot be integrated into the 5D, is it possible to go any higher than 30 fps at all? Even if we were able to get up to 40 fps, it would help the motion in the HDR feature some. I know magic lantern allows for many other lower frame rates. Something just a tad higher could be beneficial as well.

Hey guys,

So I made a short video showing what HDR can do, to show a couple of realtors in my area that I might do some videos for. Thought I would share.

This was shot on my 5D MKII with a Canon 24mm f1.4L lens. My two ISOs were 100 and 3200. I used the provided workflow to separate the frames and combine them back again.

What is your work flow? I am at a stage where I have taken the HDR bracketed images in Photomatix and at a puddle what to do next.

I use P/shop CS5 and Premiere CS5.5

i actually preferred the non-hdr version as it made the home seem warmer, lighter and more inviting...
