Jesse, care to elaborate on some of the effects and their parameters? perhaps screen grabs?

It appears to be doing both, somehow. I’m using EVO ShareBrowser.
This is what I see when I click “mount.”
I think each access port on the physical server has its own IP address, so even if we map to a drive letter, it has an associated IP address as well.
I’m not very tech savvy, so I’m not sure what information is helpful, or if my assessment of things is completely accurate.
We called EVO support, but they are in the dark about it, which is why we think it’s either a windows setting or an Adobe setting.

[Dave LaRonde] “With a properly-exposed shot — or better lighting — Then this entire discussion wouldn’t have been necessary.”
I’m quite certain you’re still missing something. The question is not at all about recovering highlights. It’s an It’s about preserving highlight information above 100 IRE when rendering to intermediate codec.

Ok… So how then is an MXF file out of a P2 camera (Panasonic AG HPX250 P) able to have a dynamic range beyond 0 and 100 IRE? Why can an inexpensive camera (compared to big production/film cameras) record highlights and shadows beyond 0 and 100, but a professional editing suite can’t encode that without a ridiculously large and relatively unknown format like an EXR sequence?
I’m more than willing to read up on help files and tech journals on the issue, but I don’t know where to look, since my concept of related terms and specs just got up-ended. Feel free to link away.
I appreciate your patience as my head continues to spin…

[Conrad Olson] “In your situation, you cannot compromise on bit depth, so you have to use a different format, but sacrifice file size and realtime playback.”
I understand. I think my confusion came in at “10 bit.” I thought 10 bit was a higher dynamic range than 8 bit. So when I used 10 bit codecs and they clamped, I was confused.
I suppose this is not the case?

[Conrad Olson] “If you are pre-rendering something to continue using in After Effects”
Yes, I am rendering something (pre-color grading) for continued use in AE. So I need the color space.
[Conrad Olson] “you will need to pick a format that supports 32bit floating point values, which realistically is only EXR”
I have never ever heard this before. In my opinion, it needs to be more prevalent in talk about intermediate codecs.
And just why in the world don’t more codecs support high dynamic range?! seems like everyone would need that kind of functionality, since color grading is usually done last.
[Dave LaRonde] “AE’s good at helping a little bit. It can’t work miracles. Unless I’m missing something — something that could be explained by a screen shot of the footage and not Color Finesse — I’d say a re-shoot is in order.”
Yeah, I’m afraid you are missing something. The first waveform is the original footage. The highlights are blown out, but the subject is properly exposed. The second waveform is the same footage, rendered out of AE and re-imported. the color space above 100 IRE is completely gone. That’s the thing: i’m trying to preserve highlights, not recover them.

Same desire, same search, same results. Anyone know of a way to get render notifications on PC?

I have done this very thing in post using the corner pin method described above… be prepared for a major headache. corner pinning a frame so that an image within that frame (that has perspective distortion) becomes full screen… is no quick, fun task.

OK, I’m a dork… I affirmed that it worked, but I had forgoten to switch on motion blur, which is what illuminated this problem to begin with… And it was still spinning! I can’t for the life of me figure out why!
Here’s the 3-frame progression of the problem with the original z-rotation values.
-179.93
-179.9626
179.9956.The z-rotation values were changed because of the expression, but the image didn’t respond! It was as if the expression weren’t even there, even though the final numbers were correct.
So then I tried “Convert Expression to Keyframes” and it works wonderfully (I double-checked this time).
Why?! Grr!

So “?” = “then” and “:” = “else” is that right?
