Hello ML Forum!,
I've just completed a two week process of trying to figure out running the provided HDR Video "User-Friendly script" (on Magic Lantern user guide) and am now looking at the finished products (or what's left of them).
It seems the beginning of the clip in some of the files looks nice and HDR'd - and then all the frames end up the same a few seconds later - blown out. Almost as if the program got confused on which frames to split and just went with darker or lighter ones. It hasn't happened on every clip, but on enough of them to warrant a "WTF is happening".
I have really only one clip that looks marvelous and the ghosting is not there. Here's the raw example:

Then I have others that are almost ridiculously ghosted. Here's an example of one of those:

I have realized that this was my first time filming in HDR so on a lot of them I was moving the camera too quickly, or using a horizontal pan, so those i'm not worried about because that's a dumb mistake I made. This probably fell into that category, i'm not sure. (Let me know if yes, I was just moving camera way to fast)
BUT my real question is that on some clips I would start the "main.cmd" and 'Virtual Dub' would open up and start flicking back and forth splitting into A&B frames - seemingly awesome and working. Then, for (to me) no reason at all, others I would activate the "main.cmd" and immediately this popped up:
"Virtual Dub Error: Avi Synth: Accurate frame seeking is not possible with this file"
Then I tried it out with another clip and that one worked - so it's almost as if the clips need certain requirements to run smoothly through the Virtual Dub as well as Enfuse.
Is this the case? Is there a required amount of Dynamic Range needed for it to properly recognize? Why is it so f*cked?
Thank you very much. Any thoughts AT ALL are so appreciated
