1080p 50p/60p would be great for HDR video, because we could get two 25p/30p streams and the shadows would not suffer from optical flow issues... just the highlights would need optical flow. The great dynamic range in 1080p!

nikon, panasonic and sony already have 1080p 50p/60p in their dslr cameras, and Canon already have some powershoot cameras with the new digic 6 processor and 1080p 50p/60p video, so maybe the next Rebel 750d will have this amazing feature...

I know I can do hdr video in 720p 50p/60p, but aliasing is realy bad in canon low budget 720p dslr, so I am hoping for the 1080p 50p/60p in future canon low budget dslr cameras... Maybe in 750D next year?... fingers crossed!...

The 70D has a sensor where each pixel is a combination of two pixels, a dual pixel system for autofocus.

The idea is to use the 70D dual pixel system to enable two different iso exposure in each pixel and merge the two exposures in camera or in computer to get HDR video. Similar to the 5d3 dual iso in raw, but using the 70d dual pixel in H264 MOV instead of 5d3 sensor lines in RAW for the different iso.

This would solve the motion problem from the hdr video using different iso in subsequent frames and would solve the aliasing problem from hdr video using different iso in lines.

Maybe Canon will do this in future?... ML team could do early...

Would be possible for the Magic Lantern Team to develop a function in the Magic Lantern Firmware to allow us to load custom picture styles from the SD card?

It would be nice because Canon cameras just allow to load 3 custom picture styles and there are lots of interesting picture styles around designed for different situations.

It would avoid the need of using Canon EOS Utility software and carry a notebook or a tablet to the location to load picture styles to the camera.

If this feature could be implemented we could have a folder inside the SD card with lots of picture styles to chose and load to the 3 customs positions in camera.

Thanks!

In my tests with T3i 600D shooting 768 x 423 @37,7fps and 960 x 544 @ 24fps and upscaling to 1920 x 1080 I found the best solution for removing aliasing:

Red Giant Magic Bullet Instant HD 1.2 (99 usd plug-in)

Best settings for 768x432 and 960x544 resolutions:

output size: custom
1920 x **** (do your aspect ratio calculations) for 960x544 it is 1920x1088, for 768x432 it is 1920x1080
lock aspect ratio: off
filter type: better (important, "better" is even better than "best")
sharpness: 13 (more than this hurts the image)
quality: 8 (more than this hurts the image)
antialiasing: 10 (the maximum possible)

these settings I found after try everything with careful comparisons

you will not believe your eyes.

Hi,

Please, what would be the smallest device to install Canon Utility and connect to camera to change Picture Styles on set location.

The EOS Utility just install in Windows XP and above...

Would be great to have a version of EOS Utility to install on a SmartPhone and connect to camera via USB to change PS

Even a Java version to work in default Cel Phones...

thanks

Question is:

Is there a software which allows to do pre-grading in a DNG file sequence in the timeline instead of in a plugin window? By pre-grading I mean to manipulate the 14 bit DNG file to recover the shadows, to recover the highlights, to do white balance, and so on...

Something which works for raw DNG file sequence in the timeline in the same way we can apply effects in a MOV file to do grading on it...

thanks

This filter is designed to clean aliasing and moire in 1080p canon dslr video.

I was wondering if it can clean the moire in 720p canon video because 720p is perfect for Magic Lantern HDR.

Does anyone own this filter to do a test in 720p moire?

Thanks!

GH2 720p 50p and 60p is good resolution and GH3 can do 1080p 50p and 60p, this is perfect for HDR video using the Magic Lantern Firmware principle.

So the suggestion is Vitaliy Kiselev from Personal View  and Magic Lantern team work together to implement HDR video to the GH2 / GH3.

How do I chose a camera: Remember you do not need to agree with me. What is good for me can be bad for you. But if you want better DR for an affordable price think about this:

First I was hungry for a high resolution, moire/aliasing free, no compression artifacts camera. I could not accept defects in the image. So when the DSLR revolution begun I waited until the almost perfect image camera was released: the hacked GH2.

Looking further, There was another must have features:

I found I could not live without an articulated LCD. Carry, install and handle an external monitor is annoying. Weight on backpack and over the camera, size, batteries to charge and so on.

Good low light performance, at least iso 3200 was a must too. In some tests I found the human eye can see the same of 6400 iso at shutter 1/25 and f1.4, so if the camera can do this it is better.

Small, lightweight camera.

Affordable price, no more than 1K usd.

An EVF would be great, but without it I can use a dslr loupe.

Manual audio control, another must to avoid hiss using a preamp and also get constant audio level.

low noise at low light or, if there was noise, not so hard to be cleaned with denoise software.

I like big sensors. I come from a full frame 35mm still photo background and big sensors delight me. But the GH2 won the game due to the amazing image quality.

At that time I was not worried about dynamic range or about slow motion resolution. 720p slow motion in GH2 was good enough.

I even got used to the lack of headphoes connector and accepted work looking at the audio metering on screen or use phones connected to the wireless receiver.

But suddenly the highlight clipping in GH2 and the no option to get good shadows at same time of good light area start to annoy me. The i.dynamic feature does not work with legacy lenses, it just works with native/electronic m43 lenses, and it does not solve the problem at all. So I started to look around on internet to try to find the "magical camera" a GH2 with better dynamic range. But the answer was simple: it did not exist. But new models and hacks starts to show up.

The BMCC: 13 sftops DR, but it is not for me. no articulated lcd, maximum iso just 1600, difficult to do handheld shooting, not expensive for many people, but expensive for me, small sensor, large file sizes and expensive storage.

All other affordable cameras do not improve the DR enough to worth buy.

I even started drol about the VG900 due to the camcorder form factor and FF sensor, but the DR is not that great to handle highlights.

I know magic lantern HDR video was laying around since december 2011 but there was some issues I did not like. To work in 1080p it needs optical flow and it gives some annoying artifacts to the image movement. And working with 720p in Canon cameras was considered by me the "never option" due to low resolution, softness, aliasing, moire and so on.

The Magic Lantern HDR uses different iso in alternate frames to get two streams to merge in post. If you work with 720p 50p you get two 25p streams and you just need to do optical flow in the highlight stream to do merge, so the movements are good.

I did a research in reduser forum and people says you just need to interpret footage to change 25p to 23,976p, no need anything else, audio pitch correction is an option, but people say tv stations in europe do not do it. The ML allows to work with 48fps, but without audio, so 50fps is the way to go.

I become so hungry for DR I start new researches about the Canon cameras in 720p quality. I downloaded lots of videos from vimeo and review websites And I found it is not that bad. It is bad if you put it side by side with GH2, but if you look at it alone, to be honest: it is good enough!

Resolution is not everything, dynamic range start to become more important for me than resolution and there are some shoots impossible for any affordable camera to do, like a person inside a house against a opened window. The ML HDR can do it, and can do great! Vimeo have lots of videos showing this, just search magic lantern hdr. Also search for T3i 720p to download some videos to see the quality.

If you know how to work with the Canon 720p it can be good. tripod and shallow dof helps a lot, but do not feel tied to this. You can do handheld and architecture no problem. People who watch the videos will look at the main subject and will not be looking for image imperfections. The 50 inch LCD tv sets from 10 feet distance shows no significant difference between 1080p and 720p. We keep looking at our computer monitors so close and due to this we get hungry for resolution, but if you look at a 720p DLP or 3LCD projector in average distance the image will be amazing!

So after this conclusions I found the T3i 600D with HDR magic lantern is THE camera to go. Also Canon cameras have the Highlight Tone Priority function. It improves 1,3-1,7 fstops highlight over GH2 and there are some picture style profiles which allow even better DR in 1080p: Lightform, Cinema PS, Visioncolor / Visiontech, Marvel

The T3i 600D have all features: good codec and datarate, sdhc and sdxc cards, manual audio, articulated LCD, 6400 iso good enough to clean, aps size sensor, affordable price, image stabilization in kit lens, can use nikon lenses, good DR picture profiles to load into camera, highlight tone priority, 3,5mm mic jack, magic lantern is almost finishing the audio monitoring and agc disable for it, but canon original firmware allows manual audio control also. Also ML allows peaking, zebra, histogram, vectorscope, waveform, HDR video and lots of other features. It has manual exposure: iso, shutter and aperture, also there is a company developing a moire/aliasing filter to fit near the mirror which can clean the image imperfections. It is shipping for 7d and 5d and almost shipping for T3i.

So why will I keep myself a resolution slave? I like the Canon 720p quality to do better DR with ML HDR or with HTP and picture profiles. It is very cinematic in a projector. 115 inch screen from 10 to 12 feet is great for 720p.

Remember you do not need to agree with me. What is good for me can be bad for you. But if you want better DR for an affordable price think about it.

Hi all, my first post!

I am considering buy a 600D T3i to do HDR video. So...

I would like to know if I can use the options in the original canon firmware to do manual audio adjust even if the ML is instaled.

I want to to go to Sound Recording Menu and change Sound Rec. to Manual and adjust the Rec Level. Is this possible?

Thanks.
