Raw Video / Re: Current raw video capabilities - All ML cameras
« on: September 01, 2013, 05:00:37 PM »
but I thought that producing a video with 80-95 MB bitrate would demand a card that is capable of faster writespeed than 40 MB/s. Maybe I'm interpreting these numbers all wrong???
The bit rate of that 80/95 Mbps video is is Mb/s, not MB/s.
95 Mbps = 11.875 MB/s.

Raw video with lets say 80MB/s, has a bitrate of 640Mb/s.

When i import into resolve and apply the blackmagic film color space, the video looks flat and it feels like loosing some color information.. When i apply a look onto that bmcc - a 3dlut it doesnt look right..
When you apply BMD film in resolve you get a very flat look. That doesn't mean you loose the color information, it's still stored in your raw file. From this point you can apply a LUT, make a node for example and choose the BMD film lut (3D lut). For me this works perfectly. The BMD film lut is very colourful, I do turn down the saturation from there.

are you aware that the progress bars lock after processing about 1/4th of the frames?
it still processes all of them, but the GUI greys out until its done if I click inside.
Same here (windows 7).

Raw Video / Re: 50D - 14bit raw video builds and test results

re: raw video

I'm just wondering if hardcoding common aspect ratios might be a better idea as a lot of the current options will likely never be used by anyone and might confuse some users. Maybe just keep SD, HD and Full HD + cinema ratios and x1.33, x1.5 & x2 options for anamorphic shooters?
Please leave them in... I love the freedom and creativity it gives. The more the better!
For anamorphic I use lots. 3:2, 4:3, 5:4 at various sizes.

Odd sizes could be in an 'advance' menu maybe if its a problem for others?

Thanks for the detailed information. Will give it a try.

I can't seem to get good speeds with that build Gregory. 65-68MB/s in all modes and all resolutions I've tried... Komputerbay 64GB 1000x.

I missed the last few builds since I was away for a few days. I might be doing something wrong. Will check some of them to see if speeds get better.

Good idea :) I think it needs a bit more 'structure' to get started though. If 20 people start editing this document at the same time, that's bound to be inefficient.

What is the plan? What should be in it, what should not be? (I think it should be about raw - there is plenty of documentation for vanilla ML).

Make everything from scratch or try to collect all the available and relevant info into one place?

I think the latter is the easiest way. We could mail some websites who wrote tutorials for example to ask if we can include their tutorials/text (with credits/back link).

Distribution - how? Google Docs can be nice, but a public editable document isn't a good idea for distribution. A PDF is too easily outdated. Maybe make one final Google Doc / Presentation that is editable only by a few moderators who can keep it up to date?

General Chat / Re: EOSHD $20 "Raw shooter's Guide"...
« on: June 18, 2013, 01:26:16 PM »
Agree with g3gg0.

Don't like it? Don't buy it. It's a free world we're living in.

I haven't bought the guide and I won't, because I've been following the developments for hours a day the past few weeks. Small chance I'll find something new in there that makes it worth the money.

But hey, if you want to jump into the game now... this might be a good buy. Of course, it would be cool if someone would make the whole thing for free. Actually I've been planning to make a simple (free) tutorial video to do raw on the 50D (for beginners). It's a lot of work though so I never get to finish it. Even something small like that. Imagine putting the whole guide together.

I have more respect for this pdf - that is the only available document right now - than all those book publishers with their 'how to'  crap books. Especially the photography ones made by shitty photographers.

Anyway, why bother complaining about it. Make a guide yourself - start a topic or a Google Doc where we can all collaberate on making the ultimate ML raw guide for free! I would put some time into it.

And to all the 'donate to ML!' sayers - there is currently no way of donating directly to ML... So that comment doesn't make any sense.

Raw Video Postprocessing / Re: The CinemaDNG Discussion
« on: June 18, 2013, 12:01:31 AM »
I'm getting weird results in Resolve when loading CinemaDNG's converted with raw2cdng.1.1.6. I'm shooting with the Canon 50D.
If I open the frames in ACR, they look fine. In Resolve there is a faint blue/orange coloured line inside of the frame.

See screenshot here: http://www.magiclantern.fm/forum/index.php?topic=5586.msg52177#msg52177

Could this be caused by raw2cdng? I don't think so since the DNG's look fine in ACR. Could it be a 50D problem? Anyone seen this and knows a fix for Resolve?

I will post my experiences with new builds here.
Latest build I've been using is ml-2013Jun16.50D.109.go.unified.b93d6ae2b30d. Will report back on it soon.

11
Looking very good! Haven't tried it myself yet, but definitely very interesting. I wonder though, what would be a good grading workflow? You could edit in Premiere and export to Prores 444 and go into Resolve maybe, but is there a possibility to export as .raw again, or dng or even better cinema dng...?

I've got a bunch of DNG files I want to proces in Resolve, but I already deleted the .raw files... Any chance I can put those DNG's back into a .raw or convert them straight to cinema DNG? tips?

Nice overview. I think the 50D is a bit underrated for low light at 'average' - I haven't done many comparisons with the 5D2, but in a small one I did, I think the 50D might even have the edge. Will try to do a better test next week when I have both available.


14
For 50D: You can't use cineform.... it either does funky colors or stuff like this. Unusable directly... need to output to cineform from like AE.
Cineform 444 works for me (installed the cineform studio premium trial). Made my last 2 video's this way...

15
I experienced the same problem with CineForm 444 files, rendered from RAWanizer. Made an edit in premiere, exported a finalcut EDL, imported in Resolve, but the clips are in a different order.

Will check out the tutorial to see If I can make it work.

By averaging the black areas from the DNG I've asked you to post a couple of times...

http://www.magiclantern.fm/forum/index.php?topic=5586.msg44299#msg44299
Sorry a1ex, there is no Silent DNG option on all of the 50D builds I've been using.
I'd gladly help out, but in this case, I don't know how.

How can I determinate the correct Blacklevel? (for the 50D). Default was at 2037 but that completely crushes the file. I just tried random numbers, around 1800 gives about the same exposure as Raw2DNG, but the colors are different when opened in ACR.

Anyway, it's workable, going to find out if my computer can keep up editing cinemaDNG in resolve... Thanks for the development!

Where would we buy the sensors and where would they fab it without huge up front order?

www.cmosis.com

They're in Belgium, small company, startup. Great future ahead though.
They make the 24MP fullframe sensor for the new Leica M and (not officially confirmed, but they don't deny it either) the BlackMagic 4K.

Not saying this all isn't extremely difficult. But I'm pretty sure CMOSIS would be open minded :)

Just did a clean install of RAWanizer with the updated .exe, but it failes at creating MP4 proxies:

Hey 5D II shooters. Need a cheap back up raw capable camera?
How about a 50D?  8)

ML with raw hack on the 50D. It is unbelievable... Love you guys  :-*

I'm posing my tests here:

I just cannot believe I bought a 300 euro camera and can shoot raw movies  :o

Raw Video / Re: Raw Burst on the 50D
« on: May 25, 2013, 11:00:22 PM »
I'm using a 90MB/s UDMA7 Sandisk 32GB Extreme Pro, getting reliable recordings up to about 50MB/s on the 50D.

In a USB3 reader I get higher scores, so I think the camera is limiting it, but it would make sense for you to get better scores...

This is great! Seems to be the easiest way to preview the shots right now. Thanks for the app!
