I think you misunderstand my intention. I’ll attempt to elaborate.

The goal is not to run the AEP in order to run the script. That would, indeed, be backwards. I’m conceiving of a script that loads lots of pre-created elements for the user, into their own project. Rather than do a boatload of scripting to generate these elements, it would seem much easier to have an AEP full of these elements (like comps and such) that the script simply opens and imports. So the AEP is simply a resource file that the script needs. The script is kind of an import tool, invoked within whatever project the user is working on.

Which is why I’m trying to think of a logical and reliable place for the resource AEP to exist for the script to call upon it. It seemed logical to me that it reside along with the script itself, making “installation” simple, and to my human brain, seems like a place where it could be “found” fairly easily… if I could deduce where either the ScriptsUI folder is, or where AE is running.

Does that make more sense?

[Ryan Wieber]

…really? This is asking the impossible? I mean, come on, at the very least, my backup plan is to do an OS check, and based on that, simply guess the usual file paths it tends to be installed to, until it hits one that exists. I’d think that would work for many cases… but not all.

Doesn’t it seem like, when After Effects is running, that it would know *where* it’s running?

Another option is to encode in QuickTime with the PNG codec, which was made speficially to be a widely-compatible, fully lossless compression format.

If you can tape in 50 FPS, then you’re slo-mo is done for you. Just interperet that footage at 25 or 29.97 FPS.

I think you may mean 50i, in which case, yes, you want to film interlaced.

For me, all I have to do is a time stretch of 200% on the interlaced footage and After Effects is smart enough to siply pull from each field to build the full frames. Frame blending is unnecessary.

Once you’ve done that, you should have progressive frames at the framerate you want, and any field business you do after that is up to you and whatever you need for your final output.

[Ryan Wieber]

And this works “between” frames? No time remapping needed? I’ll have to look into it.

[Ryan Wieber]

Yeah, I know about shutter phase and angle. That’s not really what I’m asking about. I’m talking about the ammount of subsamples AE uses to create that blur. You might think of it like “quality” or “steps” if “subsample” isn’t particularly illustrative.
