HI all,

Fisrt : I wanted to say I'm sorry because my English is very bad.


I'm looking for a quicker solution to treat my videos. All my videos are dual iso in .MOV, for each video (about 3min) I put almost 2 hours to process complet. I use the method that cuts all the frames into two parts (one for low ISO and one for hight ISO) and together at the end to create the video. After i need to treat it in VirtualDub... BUT IT'S REALLY TOO LONG.


Have - you a solution to treat my videos faster ? Thank you in advance !

That shouldn't be possible. If ML lets you do that, it's a bug, what camera and ML build (date) are you using? It's impossible to properly recover dual ISO that's been compressed with H.264. If you want to use dual ISO you need to use raw video, and you need to use cr2hdr to convert the frames to something usable. And this is going to be a slow process pretty much no matter what. If you don't have lots of time to spend in post processing, avoid using dual ISO.

@dmilligan
He says dual iso, but probably means that mode where ML alternates iso between each frame...(HDR mode ?)

@badboys46
Never used that mode, so I don't know if there's a quick way for post process. I guess not.
There's also something called dual iso:

this can be used for photo and video.
BUT this one also needs a lot of post processing. 
If you're looking for quick video solutions, ML is not the tool I guess.

It's right i have alternates iso between each frame ... With the image below is a sample configuration for the dual iso that makes me videos in MOV



I'm using method described in the user guide :

HDR video


This feature allows you to shoot a high dynamic range video by alternating ISO every other frame. Select the two ISO values from the submenu.

Possible postprocessing workflows:

Interframe script: user-friendly version

And qhen I use this method it retrieves me JPG and not CR2 or other formats.

You're mixing up two very different methods:
- Dual-ISO: Works in RAW only, not in Canon's video implementation (H.264 inside MOV files)
  Each frame has interlaced ISO inside. If you view such a frame you will see line 1,3,5,... exposed with ISO 200, line 2,4,6,... in ISO 6400.
- HDR: You get alternating frames. Frame 1,3,5,... are exposed with the "low" ISO setting, Frame 2,4,6,... are exposed with the "high" ISO setting.

The files on your CF- or SD-card: Are they *.RAW/*.MLV or *.MOV?

EDIT: Saw your edit too late. Your files on your card are named *.JPG? Do you use camera's video mode or do you take stills (=photographs)?

EDIT2: What is your native language?

- With your description, my videos are in HDR. (1,3,5 frames in low iso / 2,4,6 frames in hight iso).

- My files are in SD-Card, i'm working with 60D canon: My vidéo are *.MOV

- I'm using camera's video mode : (It's an exemple)


- My native language is french

Hello badboys46,

Si je peux t'aider, n'hésites pas !   ;)

Walter Schulz

Okay, I think we understand this part now.

To help you we have to talk about your postprocessing steps.
I suppose your 3-min videos have a filesize about 1 GByte out of the cam. Correct?

Which software do you use? Describe your steps to process your output file. And - if possible - add the time/duration each step is taking.
And some information about the computer. Windows or OS X or Linux? Processor type and speed? How much RAM? Do you use harddisks and/or SSD devices for Windows/OS X/Linux? And where do you store your files?

@Mod: Move; please!

badboys46

OUI Je veux bien !!!


EN gros j'ai des fichiers .MOV avec une frame sur deux en low ou hight ISO. Je suis la procédure qu'on nous indique dans le user guide de ML, HORS c'est juste extrêmement long 2-3h pour une vidéo de 3min à peine !

J'aimerai savoir s'il y a une autre méthode car j'ai quand même 74 vidéo à traiter, sachant que dans une demi journée je fais 1 vidéo pas plus ! :'(
Alors je cherche une méthode plus rapide pour gagner du temps !!

Merci d'avance !

Yes my video around 1GB (800-900Mo / video).

I'm using this https://bitbucket.org/a1ex/magic-lantern/downloads/HDR-workflow-051.zip
Quotehttp://wiki.magiclantern.fm/fr:userguide#hdr_video


My computer :
intel I5 4750
8GB
SSD
Windows
File store directly in folder of SSD

STEP BY STEP PROCESSING :
1 - copy/paste my video in folder HDR-workflow-051

2 - rename my video : MV_7550.MOV ==> RAW.MOV

3 - Execute : main.cmd

4 - WAITING LONG TIME :
main.cmd create 1 JPG for each frame for my video. A0001.jpg, B0001.jpg

5 - WAITING more and more : main.cmd : Create C0001.jpg with enfuse

6 - VirtuakDub Was open : Add filter near video and compress video with Xvid 2 pass

7 - Save 1 first time vidéo with first pass in folder where i want - Waiting 40-50 view more

8 - Re save second time video with 2eme pass in same folder - Waiting 40-50 view more

9 - HAPPY to finish an other video

Walter Schulz

Would have expected durations in minutes and not "Long, Waiting more and more". Those descriptions are not that helpful ...

Anyway: Please test again with virus scanner/internet security suite deactivated. You may disconnect your computer from the net during this test. Results?

You might find some faster workflows here:

http://www.magiclantern.fm/forum/index.php?topic=10627.0

All these old tools and scripts are more or less no longer maintained, because raw video and dual iso have mostly replaced HDR video. You may have issues getting them to work at all.

QuoteOUI Je veux bien !!!

dmilligan et Walter Schulz t'ont fourni les bonnes clés pour traiter tes fichiers.
Il me semble qu'il y a effectivement un problème avec ta config...

Essaies de lire les workflow en anglais et si t'as des questions n'hésites pas à me contacter.
(mais effectivement, ces outils ainsi que le HDR en .mov ne sont plus trop maintenus depuis l'arrivée de la vidéo RAW & Dual-ISO...)

Bonne chance !

@vertigopix :
On va dire que mon MAGIC LANTERN ne me propose pas d'autres solutions ^^


@Walter Schulz :
Steps 4 and 5 had a general 50-60min


@dmilligan :
I will see your website around 17h30 for learn if they are faster, i hope this.

Walter Schulz

Well, that's a slow, slow workflow!
Just tested it with a pretty small file (21 seconds recording time) and performance is just as good as yours.
Tried running it in RAM (SoftPerfect RAM Disk; 9500 MByte) and this made no difference.

Will come back with results from dmilligan's suggestions.

badboys46

I already test with pretty small file and it's not long ... 10-15min for 20-30sec video


SoftPerfect RAM Disk : If i use it I will exceed the total size of my RAM and saturated it.

Actualy i'm testing : http://www.magiclantern.fm/forum/index.php?topic=10627.0 I see it's best faster.

I cant test this : http://www.magiclantern.fm/forum/index.php?topic=8937.0 because it's for MAC / Linux :'(

Have you a tutorial for use ffmpeg with HDR video ? I see it's possible https://www.youtube.com/watch?v=s44o8MBfGg0

For 3.22min video :
1 - Create all jpg frame - 14.33min

2 - Merges imgA + imgB=>ImgC  - 1h

3 - fisrt pass video : 30min

4 - second pass video : 30min

it's faster but i see it's possible to be even faster with ffmpeg
