Forgive me for not reading through every single message possibly related to this.

I want to do the following:
• Use an Arduino controller to move stepper motors and pass 400-1200' of 3-4 perf film through a gate, illuminated with a RGBW LED lamp.
like this: https://www.magiclantern.fm/forum/index.php?topic=25117.msg228255

• Mirror Lockup to avoid vibration and keep it from flapping around
https://wiki.magiclantern.fm/userguide#lcdsensor-remote
https://www.slrlounge.com/capture-sharper-landscape-detail-by-using-the-mirror-lock-up-feature-in-your-dslr/

• Use the 5D as a film scanner at max (2-4) FPS — without triggering the DIGIC buffer overflow to shut down.

• I'd like to avoid the MLV format altogether, and instead pass the full CR2 raw file (5616 × 3744) data back to CF Card, preferably as a CDNG, but that's a big ask.
https://forum.blackmagicdesign.com/viewtopic.php?f=3&t=28920

It seems this has been done in parts but not all at once. Am I missing something critical in the forum history?

Thanks in advance!

Post-processing Workflow / Re: From CR2 or DNG to MLV?
« on: August 14, 2020, 05:30:32 PM »
So here is my extremely ugly work around.

I split the folders up into subfolders using this "split files.sh" script:
https://stackoverflow.com/questions/29116212/split-a-folder-into-multiple-subfolders-in-terminal-bash-script

Code: [Select]
Usage: bash splitfiles.bash $PWD/directoryoffiles splitsize
Which for me looks like
Code: [Select]
scaleMP:~ sines$ bash split_files.sh /Volumes/Interval_wane/Wane_DNGs/M28-1609 1000
I then have 2-5 folders of 1000 DNGs each.

I launched MLV App 1.11, using File > Transcode and Import [aka raw2mlv] and reimported the folders, one by one as there is currently no provision to select multiple folders at once, both in MLV App 1.11 and raw2mlv. Would be great if we could!

I use A Simple Finder Rename to then resequence these files back into the correct order by converting the filenames back to the original media, such as M28-1609_0001.dngM28-1609_2301.dng

Then I have to manually attach the audio back back in synch at the start of the clip in Resolve.

I am sure there's a prettier way to do it, but this seems to work.

Danne; Is there a way to use your raw2mlv script via command line — and recursively convert subfolders in a folder to correctly labeled MLVs?

Uploaded 200 DNGs files here
https://drive.google.com/drive/folders/10216M0f-Bcvr2sYx1ORM07B80mmxwHd5?usp=sharing

This sequence is 2300 frames. Most sequences are less than 5000 frames. I am comfortable running a shell version of this, but can't compile, nor use
Code: [Select]
brew tap https://github.com/ilia3101/MLV-App
because there there's no Homebrew command for it that I can see.

Got the same Posix spawn error 7 with this:
Set default to bash in terminal:
Code: [Select]
chsh -s /bin/bashhit enter then restart terminal. Now try the app again.

Please don't double or triple post. I already answered you in another thread.

Understood, but they were for 3 different solutions: MLV App, raw2mlv, Switch. None of them work on a few of these DNGs, unfortunately.

I tried that and got "The action 'Run Shell Script' encountered an error: 'Couldn't posix_spawn: error7'"

Also tried MLVApp > File > Transcode & Import. These files will read in Resolve, but won't correctly reimport into MLV app.

1.8GB zip of 1st trouble sequence is here in case you want to give it a whirl: :-*

Raw Video / Re: How to eliminate Vertical Stripes from DNGs?
« on: August 14, 2020, 04:40:06 AM »
I did that this evening in MLV App 1.1; it worked on half of my shots, but keeps choking on 7-8 other clips. I got around a few problems when the shot got cut due to an buffer overrun error on the 5D MKIII, cutting the shot short as the CF card filled up; I deleted the last few black frames from the sequence which seems to help. The 7-8 other shots are still not working, producing a "Could not open file "filename.MLV" error each time. I have tried this with deleting everywhere from the last 5 frames, to the last 100+ frames and it's still throwing errors.

I tried using this on Catalina, but maybe I am missing something. Can Switch be used to convert DNGs back to MLV, or to DNG again, but apply the Force Vertical Stripes processing upon output? I can't seem to figure it out.

Thanks!

Raw Video / How to eliminate Vertical Stripes from DNGs?
« on: August 13, 2020, 05:40:37 PM »
I unfortunately have blown away dozens of MLVs, except for a choice few, and have found that MLV App's "Force Vertical Stripes" fix does wonders for that footage.

Is there a way to "re-wrap" my already exported DNGs+WAVs back into an MLV, then re process it through MLV App to eliminate the vertical stripes issue?

Raw Video / Re: New and Old Banding Issues
« on: August 13, 2019, 10:48:15 PM »
Below are 2 examples of DNG sequences from MLVs that I shot, and disposed of the MLVs from. They were decoded using MLV Viewer 1.4.3 and

Has anyone managed to develop a script to remove the banding in post? Since I only have the DNGs at this point, repackaging as MLV and re-decoding to DNGs is impossible, so I have to find another way to remove the stripes from what I have. I am entertaining a highly laborious idea of several vertical stripe "mattes" within Davinci Resolve that would allow for individual balancing of each series of 8 stripes to reduce the banding. But it seems like there has to be smarter "automagic" way to deal with it.

Thoughts?

No noise reduction


Resolve temporal noise reduction filter applied


The second image loses too much detail in the skin and water droplets.
It's a "look" but I want the detail back.

Thanks for any ideas or help!

This could probably be fixed with some scripting adding necessary metadata info through bwfmeta edit for example.
Could you upload one folder containing dng files + wav?

There are a few here:
https://drive.google.com/drive/folders/1KiN1P894edU_Xbpes_FKIdTNv16c7QGe

Another annoying issue with these, is that the audio that Resolve sees in the folder is silent, but the WAVs in the folder have audio. I have to import each WAV for each clip separately and line them up by eye.. thank god for snapping timelines, but it's pretty tedious regardless. The 5D material was more of my B cam [Ronin-M] stuff for other parts of this series, so I have coverage, I would just rather have the ability to use everything I shot and sync it all via waveform / etc.

Thanks!

looks like I'm stuck with it.. already dumped the MLVs after not doing the research first. :/

next time. Thanks everyone!

Having this issue on the Mac. Don't have any Windoze machines to run batch_mlv on.
I have already converted all of my MLVs to DNGs via MLV Raw Viewer, and have already dumped ALL the MLVs.. so I'm left trying to "resolve" this issue with Resolve. Are there any other ways aside from lining up these clips by hand?

Thanks!

I filmed this panel discussion at the New School and am trying to figure out what the heck happened. Filmed with 3 cameras: BM Ursa 4.6K EF, BM Micro Cinema Camera, and Canon 5D MKIII running ML 1.2.3 to MLVs. I have already post converted the MLVs into DNG sequences. Camera was set to 1920x1038, 24 FPS and was not set to FPS override or off-speed recording.

When bringing the files in, the audio is consistently 20-30% shorter, even if the footage reinterpreted to 29.97.
Every other thread I read, people say their audio is *longer*, but mine is quite the opposite.

Let me know if you have any thoughts. Here are a few clips exhibiting these symptoms that I'm trying to ... resolve. ;)

Raw Video / Re: DNG to RAW/MLV/CR2? Remove banding from DNGs?
« on: August 30, 2016, 04:00:41 PM »
Also looking for a remedy for this. I converted everything to DNGs and dumped the MLVs, now trying to get rid of the banding... no luck so far.

Raw Video / recording + previewing ML Raw video via DJI Lightbridge 2?
« on: January 01, 2016, 10:08:54 PM »
I'm about to dive into the world of UAV / drones and want to fly my 5D MKIII on a DJI Spreading Wings S1000+ with a DJI Ronin-M [why? because with a CineMilled plate I can use one gimbal for handheld and drone work] and control my flight path via DJI Lightbridge 2 + A2 controller.

I noticed that martinbennett70 used ML Raw when shooting his piece for Overfinch
http://www.magiclantern.fm/forum/index.php?topic=14085.0

There are numerous slow motion drone shots and I would love to know how would you monitor and start recording via DJI Lightbridge 2 and the OSD Android / iOS App, but my experience with using an external HDMI monitor while recording with ML Raw / MLV and a firmware of 1.2.3 creates a lot of lag, potentially corrupting the files we're recording while a camera is 400' in the air. I would hate to hose the shot because I was recording at a overcranked frame rate, running out of buffer space and having it drop frames or unexpectedly terminate the recording.

Any experience or links to other relevant threads would be greatly appreciated.

Hi Martin, great job and another feather in the cap for ML / Canon platform! Wondering how you previewed the drone feed while recording to KomputerBay 64 GB cards in slow motion; I'm gearing up to do a similar shoot and trying to figure out how to monitor what I'm shooting! Thanks!

checked the black imprint on the side of the card.. it's indeed a 64GB card. F*ckers.

« on: December 16, 2015, 06:24:50 AM »
Just bought 2 128GB 1066x Komputer Bay CF cards. In OSX 10.10.5 Yosemite the finder / Disk Utility only sees the cards as 64GB. Formatted via exFat several times and the same results, in addition to reformatting in my 1.1.3 Firmware Canon 5D MK III.

from Disk Utility:

Insignia [Best Buy] USB ns-dcr30a2 CF Card reader

Wondering if the card reader is somehow limiting the available size to be formatted.. but that just doesn't make sense.

Possibly they were mislabeled at the factory, or is this a known issue?


thx!

Thank you. an oversight on my part. :/

21
Read almost every comment. Somehow I'm missing how to batch process clips with the same setting. Can you point me to the post?

22
So it seems. Is there a nice way to get MLV Raw Viewer to batch? When it opens single clips I shot yesterday with MLV Raw Viewer, they are only exporting 10-20% of the clip duration whereas Son of Batch does the whole thing [but, creates a lot more mess]

23
First.. thank you for making this..

On my first try, the folder navigation thing is a bit wonky...

So I exported 4 MLV files


and this is what I got:


I unchecked .DNG [which is what I did first time] and instead I get folders of .dn files [?] but no ProRes Quicktime movies.

Would be nice if you could make it so we can select multiple files from multiple directories.. and change directories if necessary before we start exporting.
What might I be doing incorrectly with export? Do I need to install some other secret stuff?

MlRawViewer may work one at time but I can use it to export .movs at least..

Or am I missing something?

When pasting the footer from another spanned file of shorter length, both raw2dng and RAWMagic Lite on the Mac truncate the sequence to the number of frames of the shorter sequence of 827 frames. So instead showing the entire 19 GB clip [spanned over an original 5 files] I am only seeing 827 frames instead of ... 2400 or so.

So I tried the hex value in the code from above, which would create a sequence of 1920x1080, 8071 frames [23.976fps]. Since I am shooting at 1.85:1, the res is 1920x1038, 23.976 fps, but a unknown sequence length since the clip got trimmed. Any idea on how to change the Y res in hex to 1038 so that RAWMagic thinks it's of a sequence longer than 827 frames?

I did a search of 0x438 in hex [1080] and there are just too many values & instances of it to sift through to have it make any sense.
