Can't Import .tif files
on Apr 9, 2010 at 1:22:31 pm

I'm updating a project that was made last year. I was having problems with their still images, so I checked the size and they were HUGE, and I thought it was making FCP angry. So I opened it in Photoshop, flattened the layers, scaled down, and added an alpha channel. Then I saved as a .tif.

That has always been my way of bringing stills into FCP, and I've never had problem until today.

The original problem I was having - the reason why i brought them into Photoshop to begin with - was that the image seemed to have a layer turned on that should not have been turn on. It was all scratchy looking and appear behind the subject of the image. It's weird though because there is no scratchy looking layer when I open the .tif in Photoshop. But I wanted to flatten the layers and add the alpha anyway to see if that would fix the problem.

Well now that I've added the alpha, FCP won't let me import the image. It says "Error: Unknown File Error." I can import the image if I delete the alpha, but then the scratchiness behind the subject of the image still appears.

The file is NOT CMYK and the dimensions are approximately 1280X720 at 72ppi. So the image isn't too big for my timeline either. I also have my timeline compressor set to ProRes (not HQ).

Any other ideas of what the problem may be?

If you want to save it with an alpha channel, save it as a .png not as a .tiff.

ok i'll give that a shot. That's strange though, I've never had a problem using alpha channels on .tif. In a tutorial on the COW, Rich Harrington even suggests using the .tif

Anyway...thanks!

Alpha channels are supported with Tif... No problem there.

Layers are not supported with Tif...
LZW Compression can cause problems.
32bit might cause an issue too.

Shouldn't be any problem for a TIIF, but if it doesn't work I would try with PNG or even PS.
The conversion is lossless.

Yes, it shouldn't be a problem with a .tiff but it is in his case.

the .png works! who woulda thunk?

Strange...I really have no idea what the problem was with the .tif. Like I said, it's been the norm for me, but it's nice to know I can use .png if I have problems again in the future. I had no idea .png supported alpha channels.

Thanks guys!

You can also use TG files.
All of them hold the same 8b RGB.
PNG is an older format and supports less options, but this makes the files more simple and easier to manage.
Normally I use PNG for stills and still with Alpha.
Photoshop only for the layered images.

"All of them hold the same 8b RGB."

I don't understand where people get this stuff.

the Tagged Image File Format (tiff) supports up to 32bit CMYK and 24Bit RGB imagery.

32b CMYK, means 8b per channel.
24b RGB, means 8b per channel.
I think you are forgetting the most basic maths, Gary:-)
Some of these formats can support more than 8b per channel.
If I'm not wrong PNG supports 16b per channel, but that's nothing for FC, that only supports 8b RGB.

Gary, this question is about a normal scenario where people works with normal software and hardware.
Nothing about these kind of special workflow that only people like you are able to fallow and understand.
You should concentrate in posts about 10b up workflows.
8b is too little for you.
Happy New Year.

Actually Tiff does support up to 32bit PER CHANNEL...not just 32 bit total..

From the Photoshop CS4 Manual...

TIFF

Tagged-Image File Format (TIFF, TIF) is used to exchange files between applications and computer platforms. TIFF is a flexible bitmap image format supported by virtually all paint, image-editing, and page-layout applications. Also, virtually all desktop scanners can produce TIFF images. TIFF documents have a maximum file size of 4 GB. Photoshop CS and later supports large documents saved in TIFF format. However, most other applications and older versions of Photoshop do not support documents with file sizes greater than 2 GB.

TIFF format supports CMYK, RGB, Lab, Indexed Color, and Grayscale images with alpha channels and Bitmap mode images without alpha channels. Photoshop can save layers in a TIFF file; however, if you open the file in another application, only the flattened image is visible. Photoshop can also save notes, transparency, and multiresolution pyramid data in TIFF format.

In Photoshop, TIFF image files have a bit depth of 8, 16, or 32 bits per channel. You can save high dynamic range images as 32‑bits-per-channel TIFF files.


I would not recommend trying to use it FCP...and this may be why the OP's file won't import properly...as I indicated in my earlier posting.

John,
The Tiff's 32 bits per channel option in in the export window of Photoshop since a few years.
What I'm talking is about the Tiff which we are currently using in FC.
32b can mean 8b per channel in CYMK, or 8b per channel in RGB plus Alpha channel.
For us is meaningless that Tiff supports 32b per channel when FC supports only 8b.
When I said that "All of them hold the same 8b RGB" I wasn't try to give any lesson about Tiff files, just to explain to Rob Grauer that he can use any of the familiar 8b RGB formats (PNG, Tiff, TG,..) to bring his graphics to FC with the same results.
I never thought Rob would be much interested in the possibility of printing 32b per channel CYMK pictures.
Happy Lao New Year

I have also just started encountering issues importing TIF files w/ alpha channels. Have been doing it for years into FCP. What changed for me is I upgraded Photoshop from CS to CS5. The files exported from CS5 no longer import into FCP, but if I open the same Photoshop file in CS and export the same TIF, FCP is happy. Any clues as to why this has become an issue? What is CS5 doing that is different? I confirmed it is an 8 bit TIF. I've tried RGB and Grayscale modes.
