yea, uncompressed YUV, not raw RAW. my bad :)

best compression would be all-I or IPB at QP of 1 and whatever rate the scene produces. i have a bin up already if you want to start using it and pointing out the bugs.

Yes, it would be great. I am working on a movie right now and using the camera, so this is a good opportunity to check it in real world... if i don't brick it in the meantime :)

So what is theoretically the best bitrate/lowest compression you can achieve if you have the fastest available card and you shot on 6D or 5Dmk3 (i guess they are same regarding this question)?

What is needed to get there?

More or less:

RAW = full sensor bit depth
Uncompressed = YUV422 color space but no jpeg/mp4 compression (= less artifacts in theory)

This is the holy grail for every cinematographer out there, we are able to record 444 only with ARRIRAW recorder attached to ALEXA, but 422 uncompressed is what every cinematographer/editor/digital imaging technician would piss in their pants if its achieved in DSLR camera.

Somehow I think if Magic Lantern succeeds in this, all the cameras would be much cheaper and Canon and all the manufacturers would have to improve on other stuff, it would surely be an industry-changing event.

Until now, it was possible to film directly from the hdmi output, not sure why you can't make a hack to display 1920x1080 but I hope it will get there soon...

Can somebody tell me what is the maximum speed achievable in the SDXC slot? Is it this that is limiting the quality and bitrate and can you embed an option in the firmware so it recognizes what type of the card is in the slot so the bitrate can be better with faster cards?

That's uncompressed, not raw. Should be doable at reduced vertical resolution (how much... depends on card speed).

Sorry, but what is the difference between uncompressed and raw, since I use both terms when speaking about uncompressed video?

I received an email today from mosaic engineering saying that they are going to be releasing an official VAF-6D very soon for the 6D.

I have got a similar email, so i will copy it here:

QuoteHi Vladimir--

Thanks for writing!  Yes, we are certainly going to be releasing an official VAF-6D very soon; currently we are receiving a large number of inquiries in relation to this camera, and we are making it a high priority.  At this point, we've just this week obtained a 6D here ourselves, and have begun evaluating some prototype optical parts for it, as well as the VAF-5D2b itself; we should have a final informations or an optimized design confirmed soon, with production parts to follow as soon as we can manage.

We'll keep your email address here, and let you know directly as things progress!

Thanks again and best regards--

I am aware that this topic is not about moire, but i feel compeled to put it here, since I hope there will be a software solution for moire, and we don't need to buy a $350 part of equipment which have some trade-offs (jams the shutter, mirror and changes focus)...

all it would take is mosaic engineering to develop a filter
and i've seen other videos that showed the 5D MKii having worse moire than the 6d

Hello people, I have just registered to jump into the conversation.
I have just bought the 6D and since I have replaced the 5D mkII with the 6D for shooting as a second camera for an american feature film.

A couple of facts:

1. 6D does have a moire problem, but like on every professional job, you must handle moire by being smart about costumes and sets. It does not appear on my footage.

We have tested the raw material in BlackMagic DaVinci Resolve and compared it with footage from 5D mk2, 60D, ARRI Alexa and it is much better for grading than all the material that we got from HDSLR cameras, when you shot ALL-I frames. It makes much bigger files, the SDXC cards are really fast (90MB/s) so the whole workflow just got better and faster with better results. You can do wonders in grading now.

IT IS USABLE PROFESSIONALY and we mix the footage with ARRI ALEXA footage and in the end result you really can't see the difference. Don't forget, that not all is depending on the camera, but also the lens, the lights, sets and locations, costumes, movement, smart settings so you make the footage really look alike ARRI Alexa footage. I am not an advocate for 6D, I also use mk2, but since 6D i find it much more usable because of the price, weight, framerate, ALL-I, etc...

The low light conditions and low noise are much better than the mk2 and even 5d mk3, i guarantee. This is more important because when shooting video, you don't really want to play with the shutter (you shoot in the range 50-200), and I use the aperture creatively so I can choose DOF, then I am left with ISO range and it becomes so important believe me!

I think the moire problem will be resolved by software and i hope Magic Lantern can help with this. Also, I see that moire is less of a problem when you shot with flat profiles, cinestyle etc, it becomes visible when you shoot with strong contrast, but all you have to do is move, change your position or lens, a little bit and its gone.

AF system - video does not need it! whoever shots video does it manualy, and focusing is also a creative tool, so i really can't see who needs so many AF points, since i use AF occasionaly with one AF point, the center and use it for preview, not actual filming/focusing.

I really would like to see a magic lantern alpha release and i hope you focus on:

1. Clean HDMI output - this is terrific and you can choose a recorder like Atomos Ninja-2, I would like to see it without resizing and cropping later, if its possible 1920x1080...
2. Focusing tools
3. Frame rates and formats - maximizing bitrate and raw data
4. Changing aperture smoothly, not by steps, but i feel somehow 6D already does it pretty good just outside the box.
5. would it be ever possible to watch the lcd on camera and hdmi output simultaneously?
6. Look into the wi-fi and see if its possible to send the monitoring video while recording and in preview? it does not matter what resolution is sent wirelessly, but wireless monitoring would help all of us alot.

I will stay tuned and see the progress

Thanks alll of you guys for this work, I hope I can help...
