HDR and Dual ISO Postprocessing / HDR Workflow on Mac -- Please Help!

« on: June 10, 2013, 03:48:09 PM »

Hello everyone,  I know most of you have moved on to solving a RAW workflow, but I'm back here on HDR trying to figure out how to get this to work on a Mac. I'm trying to use the "User-Friendly Script" here: http://wiki.magiclantern.fm/userguide#hdr_video

I'm an Adobe user, can't really afford GingerHDR, and tested out the Glogger Web Service. I had temporary access to a PC, and ran the user-friendly script on it; it gave awesome results, but unfortunately it was a very slow laptop and took nearly 8 hours to complete ONE shot. I compared the resulting frames to the .mp4 files produced by Glogger, and have found that the frames are of much higher quality and are closer to what I want.

So, I would like help setting up the User-Friendly Script on my Mac. The included PDF mentions setting it up in Wine, but gives no specifics, which really leaves me out in the wind! I Google searched and tried using this page (http://avisynth.org/mediawiki/HOWTO:_AviSynth_video_processing_with_WINE) to install AviSynth and VirtualDub. I had the VirtualDub program open on my computer.

From what I understand next, I took the text from the "main.sh" Shell script, and copied it into the Terminal. Below is what Terminal "said" back:

Richard-McClellands-MacBook-Pro:~ Rick$ #!/bin/bash
Richard-McClellands-MacBook-Pro:~ Rick$
Richard-McClellands-MacBook-Pro:~ Rick$ mkdir frames
mkdir: frames: File exists
Richard-McClellands-MacBook-Pro:~ Rick$ rm frames/*
rm: frames/*: No such file or directory
Richard-McClellands-MacBook-Pro:~ Rick$ rm RAW.MOV.ffindex
rm: RAW.MOV.ffindex: No such file or directory
Richard-McClellands-MacBook-Pro:~ Rick$ wine VirtualDub/VirtualDub.exe scripts\\hdr_split.avs
-bash: wine: command not found
Richard-McClellands-MacBook-Pro:~ Rick$ bash scripts/enfuse_all_frames.sh
bash: scripts/enfuse_all_frames.sh: No such file or directory
Richard-McClellands-MacBook-Pro:~ Rick$ wine VirtualDub/VirtualDub.exe /s scripts\\hdr_join.vcf
-bash: wine: command not found

So to be quite honest, at this point I'm at a loss. I don't quite understand the entire Wine process and how it all works. I've tried searching on here and on Google for more help on how to do this, but really figured it's about time to just ask the experts. If you guys could point me in the direction of a comprehensive resource, or give me some advice, I'd really appreciate it, as the footage looks quite good. I just don't feel like waiting 8 hours on one shot on the slow PC.

I'm willing to start my scratch if need be, whatever is best at this point.

Thank you in advance!

Shoot Preparation / Audio, ML, and T3i

« on: December 26, 2012, 04:54:29 AM »

Okay, I've spent the last hour or two exploring my options for capturing good audio with my t3i. I have a few questions and am hoping the more experienced users can answer.

One of the routes I'm considering is buying a Rode VideoMic Pro, and plugging directly into my camera. If I'm reading right, all I need to do then is turn off the AGC using Magic Lantern, and then turn down my in-camera preamp as well to eliminate more noise, which would be offset by the +20 dB provided for on the VideoMic Pro.

But then I also read that version 2.3 of Magic Lantern doesn't include Audio Controls for the t3i and that instead I would have to download a nightly build. Was looking for confirmation on this, and if so, where I can get the correct download of the nightly build. Also, if there is a separate way that these builds need to be installed, a link to that particular guide would also be useful.

One additional feature I was hoping to take advantage of was headphone monitoring, but it seems the t3i is lacking in this department. I found this video (http://www.youtube.com/watch?feature=player_embedded&v=BnEtj5l3acs#!) where he uses a mini-usb to rca adapter included with the camera. The problem with this is that you then lose the on-camera monitor, which I do not want to happen. So I was wondering if anyone else had thought up a scheme where you could monitor audio through headphones on the t3i, while still keeping the on-camera lcd functioning.

I think that's about it for now. I'm looking to make the camera do run & gun fairly well, and I think the the Rode VideoMic Pro is the best way to get there because it eliminates the additional burden of external recorders. From what I've seen, it also works fairly well for small interviews, in place of lavaliers (still on a small budget at this stage), which is why I'm more interested in the internal monitoring. I've done some noise removal using Adobe Audition before and think I could do the same to eliminate any residual noise; I just want to make sure I've got the method of going about the settings on ML correct, as well as that it's possible for the t3i, and where I can get the correct ML build. In addition to that, I'd really like to know if anyone has a way to monitor audio levels via headphones.

Thank you all for the responses in advance! I apologize if this has been answered in-depth already elsewhere on the forum, I did a search which is how I found some of the stuff above, but it left me with a few questions. If there's a really good topic on it, feel free to point me there too. Just trying to make sure I get this all right before I go about implementing ML and getting various audio equipment.
