Eric,

I’m not sure you will see the same info using all Operating Systems but on my Windows 7 machine I can right click on a TIFF file I’m trying to import and select properties. The properties windows has a “details” tab that shows the bits per channel.

If I show the details for an 8 bit TIFF file, the bit depth equals 24. This makes sense to me since there are 3 color channels (R, G, B) and each is 8 bits for a total of 24 bits.

If I show the details for a 16 bit TIFF file, the bit depth equals 48. This makes sense to me since there are 3 color channels (R, G, B) and each is 16 bits for a total of 48 bits.

You can find similar info using Photoshop CS4 if you have an image loaded and select “File Info…” from the file menu. The “Raw Data” tab shows something like this for the 8 bit TIFF:


8
8
8

So it sounds like Encore CS4 only likes 8 bit TIFF files (24 bits of color info) and not 16 bit TIFF files (48 bits of color info). A lot of color info is therefore unfortunately discarded…I guess?

Thanks again for your help with this.

Thanks for the quick response and info Eric.

As you suggested I resized images to 720 x 480. When I save the images as TIFF 8 bit everything works fine but but unfortunately I get the same error message from Encore when saving as 16 bit TIFF. Seems like the issue is specific to 16 bit TIFF images.

So my guess is that either the mpeg2 DVD codec that ships with Encore can’t handle 16 bit TIFF or mpeg2 DVDs just can’t contain 16 bit TIFF images. I haven’t found any documentation that proves or disproves these theories. I feel like I’m loosing a lot of quality by saving as 8 bit TIFF images.

All I really want to do is take the RAW images I shot on my relatively high end Canon EOS 5D Mark II camera and put them on a DVD (without loosing significant quality) so that they can be veiwed on a TV or PC. I thought Encore CS4 would help me do this easily.

Thanks again for the help!

I’m having a similar problem. I’m getting the same cryptic message when I try to import a 16 bit tiff file into encore cs4. Tiff 8 bit files import ok.

Been looking for days but can’t find any documentation that indicates that 16 bit tiff is not supported. Adobe Encore docs all say “Tiff” implying that all tiff files are supported.

Concerning codecs, Is there a codec that handles 16 bit Tiff? I see a lot of video codecs available for free download but how does one determine their quality?

I’m a newbie and just want to create a DVD based slideshow of the high quality photos I’ve taken with Canon 5D camera but can’t seem to get Encore CS4 to do so.

Thanks for any help!
