I just shot a car video using the MLV format. I have shot multiple times using this format before without any issues. However I am reviewing the footage now and have noticed this in random intervuls through every clip except the first one of the day.



Any ideas? The only thing I did different was I used the batch MLV to DNG found here: http://www.magiclantern.fm/forum/index.php?topic=9679.0

I am thinking about going and doing it manually just using the MLV_Dump.osx to see if it fixes it.

Video of the issue:

Shot on 5dMKIII

Thank you.

Will do!

We are actually in the process of having our own system designed from the ground up. We want to have full control over it as well as offering a few options that are not available on any other handheld rig!

Latest shoot and first one to use the RAW video on our MKIII.

This was also shot using our custom SteadiFly handheld stabilizer rig.

Here's my current workflow:

Change File0001.ASF to File0001.RAW
Opening the file in 0xED and add the footer information from known working file. Save the file.
Run the updated RAW file through Raw2DNG.
Import DNG's into Lightroom.

Here is where things are odd. In every instance I get the file to show some type of information. Some I get almost all of it. But then the next file is messed up again.

Here are 4 images from 4 files. As you can see File0002.RAW is almost completely intact.

File0001.RAW


File0002.RAW


File0003.RAW


File0004.RAW


I would pay anyone to download the files and see what you can figure out. I have an FTP server that has unlimited space so I could upload it all to you.

Thanks again for working with me on this.

Here is a video of all the ASF files together.

From what I can see the files are already in the correct order. Can you elaborate a bit more on the n*log(n) thing? Thanks.

So after going through the files here's what I can see.

I do infact have the entire clip. It's just broken up into 215 different ASF files. I am able to combine the files into 1 .RAW file and get DNG's out of it. My problem is the alignment of the frames. For each ASF file the alignment changes. The last file, 215.ASF is the closest it comes to being correct framing. 95% of the frame is there with just a little bit of pink in the bottom of the frame.



If I merge multiple files together the arrangement jumps as it gets to each new file in the hex code.

Is this fixable or am I really just screwed? I saw in the thread about fixing the Odd Pink DNGs 1% saying something about the alignment looked off but I can't find anything about fixing that... I followed the steps listed in that thread but it didn't seem to fix the alignment issue.

Thanks guys!

Ok, I am getting somewhere.

I ran a card recovery program on the CF Card. It found a bunch of .ASF files. The files range in size from as little as 20mb to as much as 1.4GB. I took the first .ASF file and changed the extension to .RAW and tried running it through RAW2DNG. This didn't work and I got a "This Ain't A Valid..." I then took a 4GB footer file from the above link on how to fix footers. After I added this and dropped the newly saved .RAW into RAW2DNG it ran! I stopped it after a few seconds since I didn't want to let it go completely if it wasn't going to work. I then imported the DNG's into Adobe LightRoom and low and behold PARTS of my footage is there. I say parts because it's in an odd order... Here is a quick screen shot.



I am going to backup these ASF files so I have the originals then I am going to attempt the Salvage crazy DNG's link above and see what happens.

Do you think this is still possible to save?!?!? I hope so!!!

Thank you. I will try the first option. I tried the footer fix and that didn't seem to work.

You'll have to manually create a header in the file. Everything up to the shutoff should be recoverable... the frames you had in memory when it turned off, maybe not.

How is this done?

I don't like that answer... haha! Unfortunately it was somewhat of an important shot, and we can't shoot again. I have been testing both RAW on the camera and these memory cards for the last 2 weeks straight without any issues at all. Because of this we decided to shoot RAW on this project since all the other cameras being used were REDs (Scarlet and EPICs). We do aerial video production and decided to use our MKIII with RAW instead of flying the RED EPIC.

I am running a recovery program on this memory card and it's finding a bunch of .ASF files. Could any of these be part of the missing footage? The thing thats confusing me is the card says there is about 20GB of data on the card but I can't see it.

Anyone else have anything I could try?

Thanks for the help.

Josh

I tried the above using an external hard-drive copy of the card. Still the same result. I get a bunch of black DNG's with odd-color lines in the top portion. Any ideas? Thanks.

Hey Everyone,
I have been using the RAW hack on the 5d3 for a while now and love it. I haven't had any issues till yesterday. During a shoot we were recording 1080p @ 24fps RAW. When I pressed the stop record button it said "Busy" on the top of the camera and the red record light was still lit. I let the camera sit for about 5minutes and when I came back it was still doing the same thing. I turned off the camera then turned it back on and received an "ERR 80" Message on the top of the camera. This didn't go away till I pulled the battery. After I pulled the battery and restarted the camera I swapped cards.

My problem is now I can't get anything off that card. When I plug the card into my computer I can see 2 files. A backup.raw and the M13-1314.RAW file. The backup.raw file is 524kb and the .RAW file is 0kb. However if I look at the used space on the card it says about 20GB has been used on the card. I just can't find that file. Any ideas on how I can salvage this? I have tried coping the files to my computers HDD but it went really quickly and after doing a footer file fix I just get blank DNGs. Currently I am making an exact backup of the entire card to an external hard drive so I can try working on the files there as if I am working on the actual card. I am hoping I get better results.

Any ideas welcome! Thanks!

Josh
