Bruce GaberNoisy import of PSD image sequence
by on Nov 29, 2013 at 11:23:52 pm

This is very weird

I've imported into AE a 19 frame PSD image sequence as exported as PSD rom LR 5. Great! images are beautiful. Then I made a virtual copy set of the same images, did some minimal color correction, exported as PSD, and when viewed in PS they are dead on. But, upon import into AE and under the same AE setting, the images are grainy. Now this is an interesting look, but not one I want. Actually I had this happen once before on a JPG import.

What's goin' on?

Thanks to all

Bruce

What is the resolution of the imported images?

e.g. Width X Height + psi.

images in each sequence are 2648 x 2648 px

Again what is the psi 72, 150, 300, 600??

Also a screenshot of before and after would help

original was 72 ppi, changed to 300 ppi with no change in the image quality in AE. I'm not too surprised as I wouldn't think this setting would have any effect on AE as it really only applicable to printed images. But worth a try.

What was surprising, though, is that when I rendered out a single frame it was fine, noise-free. So the problem has something to do with the way AE is representing the files, not the files themselves.

Working out how to upload screen grabs

DPI or PPI is irrelevant in AE. It only looks at the PIXELS.

A 2-inch by 2-inch image at 400 dpi is 800 pixels in each dimension.
An 8-inch by 8-inch image at 100 dpi is 800 pixels in each dimension.
To AE, they are precisely the same size, 800x800 pixels.

Your problem probably lies in the codec you used for rendering out of AE. It may have been ill-suited for the dimensions at which you rendered.

So what was that codec, and what was the media container to which it was rendered?

Hi Dave

Yes, I understand the concept of pixel dimensions. I was simply replying to the previous post on the thread requesting that information.

The issue occurs on importing images directly into AE. I've gone back and reproduced the export from LR for both my color corrected and original images as both PSD and TIFF. Now ALL the images show up as grainy when I examine the footage in AE. They render out just fine, look just fine in PS.

Your sage advice is most welcomed--and needed

Thanks

The reason I asked for psi is because one time many moons ago I was handed an AE project and everything had a ton of noise... the image's psi was like 800 or something. Once changed to 72dpi the noise went away.

Granted this was in AE version 4 or something, but it did happen to me once, although I can't explain... nor do I have the faintest idea why that was the cause... but it was.... anyway....

Without a screenshot of your composition and timeline window, I can't comment further to the reason behind your extra noise.

Thanks Mat

Yes, there are some really mysteries under the hood of AE. Working thru the procedure for uploading screen shots so you can have a look.

Hmmm.... do you have a good deal of experience with AE?
Is it really grainy, or is that your best description of what you're seeing?
Could it be something minor, like have the comp's resolution set to half, third or quarter?
Are you scaling up layers beyond 100%, which is never a good way to retain a sharp-looking image?
Do you have the image quality switch for the imported image sequence set to something other than best for the layer in the timeline?

I'd rate myself an experienced apprentice* AE user, been using it for about 2 years
Grainy, as in a print shot from old ISO 400 film; not blurry, grainy
Res is 100%; scaling = 100%; image qual switch = best

I'm thinking that the issue has something to do with the fact that these images were cropped in LR. If I set the layer scaling at about 40% and the screen mag ratio to 100%, the image looks fine. And as I noted before the rendered images are fine. May have to do with how AE is generating thumbnails (is that the way it works?)

It could be the cropping. Look at the horizontal & vertical dimensions of the footage by highlighting it in the project panel, and reading the info about it at the very top. If it's less than the comp size, and you're filling the comp with it, the layer is being scaled up.

You don't have any effects applied to the layers in question, do you?

Nope. The footage is 2648x 2648 as is the comp. (And speaking of comps--why does AE generate a new comp each time I drag a piece of footage into the timeline? And no, I'm not dragging onto the "make new comp icon")

AE's making a new comp when you drag footage onto the timeline? Okay, that's officially weird.

Check to make sure your AE version is fully updated... as are any any drivers for third-party cards used by AE.

That's the last piece of advice I have before you need to provide a big boatload of information.

Yup, that's what it's doing. Whether I drag footage to the layer list, the comp window, or directly onto the timeline AE generates a new comp. Perhaps this is what is supposed to happen and I never noticed it, but I don't recall seeing it before and I don't find it documented in the online help or in Meyer's CMG with AE. Weird indeed.

I'm running AE 6.0, but I just now installed AE CC. Same behavior. (Guess there's something to be said about instant access to updates with CC)

Well, you DO have easy access to CS6 updates, too. Look in the Help Menu in AE.
