i was off some time, but have another, hopefully not too dumb question:
Would it be possible to use the edmac copy routine, to copy only every second line?
So sacrifying vertical resolution for more horizontal Pixels?
It doesn´t not necessary look too bad to interpolate every second line in post, and the possibilites would be enormous, if we could use e.g. 3840 x 820 @24fps, which would result in 125 MB/s, for a Super35mm equivalent Crop Factor of 1.5. In a cinemascope aspect ratio. If you could it interpolate it to 3840 x 1640 in the post. see what i mean?

greetings

rudi

@Hazer:
It looks like the DNGs from raw2dng do not have previews. Adobe DNG Converter adds previews to the filez.

Actually, I have that feature turned off, along with all the other options. i.e. I have JPEG previews, embedded fast load data, lossy compression, and embedded original all turned off. I have "preserve pixel count" turned on. Hit convert.

Again, not sure what changes if any are happening to the original image data, but the resulting image *looks* the same and appears to respond the same to highlight recovery and so forth. Further investigation is probably necessary.

Ok, my new test clip which aren't of plants or dogs!

Every now and then I need to remove the battery and put back in before the camera will start (after re-inserting the card after offload). Using Lorenco's May 17 build. Otherwise, everything is working great.

Nice vid! You mention using komputerbay card. Was it 64gb or 128gb you worked with?

I would have preferred to be able to use Lightroom 4 processing raw. Too bad that batch processing show inconsistent results. For instance when getting highligts back whites treats differently on different frames. This is not a problem in adobe camera raw. Personally I believe the raw engine has gotten worse in lightroom 4 compared to version 3. Lightroom 3 is also inconsistent but not as much.
For now I work with fast conversion to ProRes422HQ via AE, using either the PS camera raw engine or directly in AE. It,s only one or two steps away after the files are converted. Made a workflow tutorial about this, easy to follow.

Many people process timelapses in Lightroom, so it must be possible to get consistent frame-frame exposures using it.

This plugin
http://lrtimelapse.com/
is specifically for doing timelapse in Lightroom and it may be some use for processing frames of video too.

If you don't like the current way Lighrtoom deals with RAW you can revert to the old 'process version', it's in the develop module under 'Camera Calibration' (near the bottom of the right hand panel.

Adobe says (and my experience tallies with this) that equivalent versions of Lightroom and Camera Raw use EXACTLY the same conversion engine, so I don't know why you'd have different results with the two, maybe you have slightly different versions installed, as Camera Raw gets updated more often than Lightroom, but Lightroom is sometimes ahead on big releases.

Well, I suggest you do your own testing. I tried lightroom 3 and 4. Also thought It was the exact same camera raw module but I,m getting different results, don,t exactly know why but with some clips there was inconsistencies when retaining highlights and whites in lightroom 4. I have adobe camera raw 6.7, oldie but a goldie.
Still, don,t know if I,d use lightroom since it can,t convert to ProRes without creating a unnecessary extra step converting to either tiff or jpg first. From AE you go straight to ProRes422HQ

Hi-

Wanted to throw in a quick Mac workflow tip I've been using. I haven't seen this mentioned yet; apologies if it has and I missed it:

As you have probably experienced, the raw .dng files produced by raw2dng don't display in Finder/Quicklook, Preview, FCP/FCPX, Motion et al. The data is there, but the images show up black/blank. Ater Effects and Photoshop will take them, but if you'd like to use them in other apps, I've discovered that Adobe's DNG Converter utility fixes the problem *without* needing to convert everything to a tiff sequence and step away from raw. Here's the download link:

http://www.adobe.com/support/downloads/detail.jsp?ftpID=5568

After installing the app, just select all the .dng files for a given clip right in finder and open them. This will launch DNG Converter. Hit "Convert" and you'll get a new set of .dng files in the same folder that will work fine in the above applications. You now can use Quicklook/spacebar in Finder on these new files as usual. If you have Motion, you can drag them all right into the layers palette and you've got a raw image sequence. Color correct and export as ProRes.

Note that these are still raw frames and the original image data *appears* unaltered. I haven't examined in detail so those more knowledeable in this area should take a closer look. However I think DNG Converter is just re-wrapping them in a more Mac-friendly way.

Thanks!

Thanks for sharing!!! Definitely didn't see that before. I will try to test it out later today and see if its better than current post workflow.

I'd like to thank the developers, all this work is just awesome! However I have problems with the battery consumption. Even after my 5dmkIII is off, the LED still blinks from time to time and my camera stays warm. Also, battery power goes down real fast. I have to remove the battery if I'm leaving it alone for awhile. Any ideas?

Warning: disabling the 4GB checks will result in corrupted files on FAT32 cards, if recording stops automatically.

Is File spanning in FAT32 not possible?

Some info about Adobe Camera Raw (ACR) and Lightroom:

ACR and Lightroom have the exact same raw processing engine and results, as long as they are of the same generation.

That is to say:
Lightroom 5 = ACR 8 (CC and CS6 with June 2013 update)
Lightroom 4 = ACR 7 (CS6)
Lightroom 3 = ACR 6 (CS5)

Of course different generations of ACR, like Lightroom 3 vs Lightroom 4, are going to give different results.

Starting with Lightroom 4 and ACR 7, Adobe introduced process version 2012, which automatically controls highlights from frame to frame without user interaction. This is very likely the cause of some flicker from frame to frame. You can switch to process 2010 in the camera calibration area to turn this feature off, but also loose the advances made in highlight and shadow control made in process 2012.

Upon pressing the trash button to get into ML Alpha3 for 5D Mark 3 I get the message " Script DIR Missing" when I go to load modules
the raw video module loads "successfully" however when I proceed to the Movie Camera Icon and scroll down to start after making size 1920x1080 and start regardless of the card I'm using 2 different 1000x 128 gig Komputer Bay Cards and 1 Lexar Professional 300X (which I know is too slow) It stops with the message "Buffer usage Frames 32". The other day I had more success than this...I've reformatted and
reloaded Alpha 3 twice but I still get what I've described.

I am hoping to use this in Iceland soon for a project on glaciers and global warming any assistance or suggestions would be greatly appreciated.
In the last few days I had been fairly successful with 300x cards with of course some dropped frames but the Komputer Bay Cards and now the Lexar 300x are all pooping out at just 32 frames...shutter speed is 50. Thanks for any information people can provide feel free to call me a moron if you wish for forgetting something basic but I think I've covered the bases....perhaps problem lies in "Script DIR Missing" message or in something I've got set on the Mark 3 which the Alpha software doesn't like. VIVE Magic Lantern!

@RenatoPhoto - I'm in favor of more organized raw topics as you suggest. There are so many people wanting to know the raw capabilities and specifics of their camera body or just basic info and it's making the main topic messy.

A lot of people are so eager to find out info regarding raw video that I think there needs to be a post on the website's front page with the current state of play for each camera.

Danne,

I used lightroom 4 to process my raw DNGs for my test shoot and I didn't see any inconsistent highlight treatment. I used exposure, highlight/shadow recovery in nearly every shot. I did not use the tone curve for any of my shots though, so I'm not sure if that is consistent.

Hi! Looks nice! I might try the workflow with lightroom further on to see if i,ve done something wrong. I believe there was at least one more person in here that experienced the same problems as me. Still, if anyone has AE I don,t really see the benefits going through the hassle exporting from dng to tiff and then to for instance ProRes i lightroom. Dng staight to ProRes seems faster.
Thanks

Is it currently possible to record h.264 .movs simultaneously to sd for use as proxies in editing?

I'd love to try using the RAW feature for a short film shoot next weekend but the quick turnaround won't really allow for processing the dngs before editing..

I've also tried to remove the 4GB check, but I've got files without footer (which can't be converted). So it stays there until we have a better solution.

any update on fixing the 4 gig limit?
