RAW HDR VIDEO - Batch process?

[kawasakiguy37]

I have a ton of both HDR RAW and Dual ISO RAW video I need to process. Recently I started using MLV mystic for the Dual ISO stuff and Im very satisfied with this tool

Is there anything similar for HDR video (where ever other frame is a diff exposure?). I havent been able to find much at all on this forum about processing HDR video, really stuck here

Batch process HDR video (dual ISO) would be so helpful to me right now.  Currently I'm working on 178 videos... one at a time.

Maybe some of the other guys using HDR video for real estate would be interested too.  @jbggump, @rainboy, @donjames150, @kawasakiguy37

Would a cash reward Be appropriate to offer?


This is what I would like to see the Batch Program do.

• Select Videos
  
• Split Video - With the option of Jpeg or Tiff  (Tiff Script: http://gpwrite.com/magic-lantern-firmware-hdr-video-script-eos-5d/)
• Enfuse
• Delete A and B images
• Leave C Image is separate folders (uniquely named).  I don't use Vdub to save the video.  I import image sequence to AE and go from there.  So someone else can suggest how to automate Vdub export.
• Do the next one.

I found this speed hack here, perhaps this could help too. http://www.magiclantern.fm/forum/index.php?topic=10627.0

I believe there is already a program that does batch of Dual ISO video - What I'm looking for is the fastest workflow to process HDR RAW video (every other frame different exposure), ideally with a batch script, or without.

This could be helpful. Try converting to .mov and the run this script http://www.magiclantern.fm/forum/index.php?topic=8937.new#new

I'm on a PC. Any script for that?

Opps, I made a slip up.  I meant every other frame HDR as well.   Not the Dual ISO that alternates ISO within the the image.

@kawasakiguy37 please share if you find something.

I'm am trying this for alternating ISO HDR Video: For Mac only at the moment

Thank you @Danne for looking out!

Update:

I experience the same issue as Jed,

It is the frame rate I think...I am fairly new to digital video (did Beta back in the late 90s in college).  I shoot at 29.97fps and with the dual ISO it goes to 14.99fps.  I can't really wrap my head around what to do to make is smooth.  I speed the footage up anywhere from 125% to 200%, but it doesn't seem natural...could just be me though.  Do you have a suggestion?  I did a quick video to show the differences...  200% would seem logical, but it moves faster than real life (but is smooth).

Just dawned on me...do I need to be shooting at 1/60?  I am usually at 1/30...

Also, I can't get the batch HDR to work.  It only does one file if I have multiple in the folder.

Processing on 2.7 i7 MBP.  16gb ram.

Love the program though - I can sense it will be advancing my work.  Thank you

Here is some help:

It does some of what you (and others) want, but you'll have to get the
interframe scripts working on the mac using wine

you do select the videos (one at a time, up to 6 total)
it does delete A and B frames, leaving C frames in a unique folder
it has an option for writing an avi file, but writes slow (1-1/2 mins for 4 sec clip)
Using the avi option it took 35 minutes to write ten 4 second clips. Half of that
time was the avi writing. I sent him an email about that, I don't see a need for
a 545 mb bitrate, I'm sure he could tweak that part and maybe take off the cap
on the number of files to batch at one time. Maybe make it so you could select
several at once rather than add one at a time. He does say it's a beta program.

Ok, I've found my solution for HDR video. I'm using Malcolm Debono's HDSLR Offloader program and photomatix. Photomatix works inside the Offloader program to merge the frames. It fills all my needs. it's fast (Processed a 5 second clip in 1 min, 20 sec), it takes an unlimited list of .mov HDR clips, and it creates individual output files. Input your list, walk away and just rename the files.  I was using 720p at 60fps so that I could control the speed easier, but I was getting too much moire. I saw that 1920x1088 at 30fps had significantly less moire (haha, could be read as less more), and if you output from the Offloader program at 60fps then it can be slowed down to your liking in your editor (with a tiny bit of stabilization). Photomatix has a free download, they want you to pay, but there's no watermark on the output nor time limit for using the download so you'd be on your own to buy it or not ($100 for the pro version which you need).

edit 5/29/14: This is still the best option for me, but I've discovered the output is not as good as the interframe script, but easily fixed in post by turning the contrast all the way down (-100) and adding +50 for sharpness (of 200 in my editor). Comes out great, I think.

edit 7/5/14: I've changed my mind about 'always' turning the contrast all the way down, in some light it works, others maybe 1/2 contrast, others normal contrast. Depends.

edit: 6/4/14: I downloaded an old version of Photomatic (vers 4.0.2 64bit and it processes MUCH faster. A 15 second clip using the laterst version took 3mins 45sec and with vers 4.0.2 the same clip took 1min 45sec !
