View Full Version : 5DmkII now with 720P with magic lantern raw
Ted Ramasola May 15th, 2013, 03:18 AM Most of the video is shot in 1280x720 upscaled to 1920x1080. At the end are some chart tests to compare the rez of the different RAW video resolution with native h264.
Also some shots at 1880x720 and 1880x1080.

Wow, Magic Lantern has come a long way since early days when we first dared run that code on our cameras. I can remember Trammel's warning that we might end up with a brick.
So at this point, I would like to experiment with this and compare with my Black Magic camera. Not sure what version or where to get it. I am signed up with the ML and have 2.3, but I understand this is alpha, and would like to get some work in on it. How do I get into the Alpha stuff at this point.
Ted Ramasola May 15th, 2013, 09:20 PM Chris,
Sorry for the late reply, I've been a day sleeper lately. Do you currently have magic lantern in your 5d2? If so what version?
I'll fill you in on the module loading that's working in my camera once I know what ML version you have.
Everything is moving so fast over at ML forums, information is all over the place! I hope the dust settles soon.
Chris Barcellos May 16th, 2013, 12:36 PM I am running the latest official version 2.1.2-ml-V2.3.
Stephen de Vere May 17th, 2013, 08:20 AM So am I right in thinking that the 1080/24p RAW Magic Lantern recording onto CF card is of much higher resolution and cleaner than the uncompressed HDMI output, due to bypassing the default poor down-sampling and processing done in camera ?
Anyone done any res chart shots yet ?
I have avoided DSLRs for HD video so far as they don't seem to be able to achieve a similar and clean sharpness as my EX3.
Chris Barcellos May 17th, 2013, 12:40 PM Really very early in developments here. A lot of questions out there yet.
See Ted's video above. Some rez charts at end.
Stephen de Vere May 18th, 2013, 04:46 AM Thanks for pointing out the res charts at the end. Maybe I'm not 'reading' them correctly but it doesn't look encouraging on the resolution front.
Maybe the 5D Mk3 is different. I had read that the 1080 ML RAW video looked as good as 1080 stills from the 5dMk3.
Larry Vaughn May 18th, 2013, 10:12 AM What is the advantage of upscaling if you are going to publish web video in a smaller window than your upscaled resolution?

Hi Stephen,
Charts are charts, it is what it is. :) the 5d mkIII has more potential as it is, as for the 5D mkII which is what I have, I strongly recommend the mosaic filter with it for serious work other than cats and flowers. VAF is essential for the mkII weather its Magic lantern raw or h264.
Chris Barcellos May 19th, 2013, 01:02 AM After adjusting frame rate, I am shooting 1000 frames of 720x 1280 on my old 133x cards without stopping. This at least provides zan idea as to how ML works so far. I will do some testing tomorrow. I also have a 32gig 1000x card coming.
Note that when you select that frame size you are actually cropping sensor image. ML provides a guide on screen for the a tual image area.

Ted,
Thanks for that info - i now understand your test much better. I have much to learn about DSLR video on various cameras.
Do you know if the MKIII is different than MkII regarding built-in filter then ? Perhaps it is just that the slightly different resolution of the MkIII sensor easier to downscale to 1080 HD gives it a better edge video-wise ?
Ted Ramasola May 19th, 2013, 04:19 PM Stephen,
in the mark III, canon addressed the problem of the moire and aliasing by putting in a more agressive OLPF effectively solving most of the moire and aliasing, BUT at the expense of sharpness for native h264 video. Users complained again, some users even went as far as removing parts of the filter in front of the sensor without much improvement.
The magic lantern raw hack however gives us dngs before h264 compression allowing both cameras to gain in detail and resolution. The mkIII has better results out of the box due to an aggressive OLPF, the mkII still retains its usuall aliasing and moire, which can be controlled by the mosaic VAF filter.
