I've been following all of the threads on the HDR workflow but none are Vegas specific. There is one guy who has created a MAC program that will separate the HDR file into 2 streams but again, not on a PC. I think I can figure out how to blend the 2 streams but it's the separating part that is over me.

Two ways I can think of. One, render as .jpg and separate into odds and even - only way I know to do this is view .jpgs as medium icons, squeeze into two columns and select one side with mouse - if any one has a more elegant way, script or rename utility, I'd be interested. Cut and paste selected sequence to another folder. You can also then batch render with photomatix for tone mapping. Other way, in event properties, change playback rate to 2 and render - this gives you every second frame. Then, restore playback rate, delete first frame of original sequence, change playback rate to 2 and render - gives you every other frame. Interested to hear your thoughts about blending. If you work out how to blend the tracks in Vegas, you could do it without intermediate renders - just duplicate your footage on different tracks, and follow process above.

Rainer,

Interesting ideas. Will work on some this weekend and let you know how I do.

I tried the image sequence route and it seems to work. I got stuck on the image sequence import for a bit. You have to rename the files because to import the image sequence, Vegas wants all of the images to be sequential and with this method, you are left with all odds and all evens. There is a tool called bulk rename utility that takes care of this easily. Once files are renamed sequentially, you can then import as a half frame rate image sequence, then render back out as 1080 24p mxf.

Now for the blending. I'm experimenting with compositing modes and am finding that my trial footage is horrible and I need to shoot some better footage. I think I will try the 720p/48fps mode as described in the vimeo forums also.

Lots to play with, but Rainer definitely gave me a starting point.

Thanks,
JAB

If you follow the link to Vimeo posted above, there is a link to an AviSynth workflow which will work pretty elegantly on the PC. You can frameserve to AviSynth from Vegas and there is some guidance on getting this working in my lengthy web video tutorial.

thanks Nick! Very helpful

JAB,

I'm just now looking into this and it is thus far, waay over my head.

Did you find a workflow that is usable?

Thanks,
Keith

According to the tutorials on the web you have to duplicate the layer (2 tracks). Then move 1 layer, 1 frame left or right. This is because every alternate frame is shot with either 100 or 160 ISO depending on the HDR level increment you have set. Then you play around with opacity between the 2 tracks.

I'm going to give it a try.

I expect to see this HDR feature in future cams

Workflow is demonstrated albeit not in Vegas however the FX's used are in Vegas.

You crazy not to install Magic Lantern if you own a DSLR Canon camera.

3D leaves me cold, but HDR? There's a most ardently desired object. When are we going to see that in main stream cameras?

I'm trying to make a Magic Lantern HDR Vegas workflow. The video clip is double PAL with every alternate frame being ISO bracketed between 100 and 400 ISO.

Video clip = HDR video 50 fps, bracketed ISO 100 & 400
Insert and copy the clip onto 2 seperate video tracks.
Right click video1 Clip - Properties - set Playback rate to 0.5
If you play the video1 clip you'll see the clip flicker between 100 ISO and 400 ISO at 50 fps
Delete the first frame from video 1 so that its 1st frame is darker. Then right click and set playback back to 1.0
When you play back video1 you'll see the clip is playing only the dark frames of the clip.

The issue I'm experiencing is that although I see only the dark frames (every 2nd frame) in playback it renderes out the lighter frames ignoring the fact that I deleted the first light frame.

Anyone else trying HDR video workflow?

So I shot a lot of HDR video using Magic Lantern on my Canon 60D and need some Vegas workflow help.

This is what I understand of how it works. The camera shoots double PAL which I assume 50 FPS. The camera exposes every 1st frame at 100 ISO and then every second frame at 800 ISO.

How do I get Vegas to read every 2nd frame on one timeline and every 1st frame on another timeline?

Craig I had a crack at it and this is what I got.

Right click clip disable resample undersample rate .5
Triple clip on timeline middle track create subclip delete dark frame
This will give you 2 clips 1 over exposed and 1 under exposed
Use the overexposed track as a lumens mask on the underexposed track
Check end for workflow layout.

intro few seconds of playback @1
