Can't use TIFs

Athenian wrote on 9/1/2008, 8:12 PM

I'm creating a slide show (Using VMS 8.0) and I'm unable to use any TIF files. At first I was getting errors about the QuickTime plug-in and now that I've updated that, VMS is just saying that it can't open them; that they might be corrupt. This is happening will all my TIFs and they are fine in all my image programs.

Is there a secret to using TIFs in slide shows or are they just forbidden?

I have heard that Vegas has trouble with TIF and that it prefers PNG. I would use Irfanview to batch convert them.

Thank you Terry,

Since I only have 5 or 6 TIFs in this project, it won't be a hardship in this case. I use ThumbsPlus to organize my images so I can batch convert these problem slides in a few seconds.

It would have been nice if there had been some sort of documentation about this problem. I wasted a lot of time trying fix something that apparently can't be fixed. Do you know if the latest version of Vegas has the same limitation?

You might also want to check the size of your stills. If they are really high rez you might want to reduce them to no more that twice the project resolution.

Converting the images to PNGs did indeed work as advertised.

The TIFs were included in the media bin because the images are irregular shaped with a transparent backround. All of the images for the project came from a folder with 300dpi files. Afterr resizing the TIFs to 100dpi though, the import ran without a hitch.

Thanks for both tips.

You'll do yourself a favor with your video editing if you stop thinking in DPI. It's an utterly meaningless measurement in Video. What matters are the pixel dimensions of the images, such as 2048x1536, or 640x480, etc. Start thinking of them that way now and you'll be a lot farther ahead.

Technically, changing an image from 300dpi to 100dpi doesn't change the dimensions of the image at all. It's still the same size. The dpi setting merely specifies how much paper it should be spread out over when printed. A 1024x768 image at 300dpi will print about 3.25 x 2.5 inches. Resizing it to 100dpi would still be a 1024x768 image that would print about 10 x 7.5 inches. This means that when you said you "resized to 100dpi", what you apparently really did was shrink the image to 1/3 the size. This is the important part, not the dpi setting.

I use tiffs and pngs in Vegas right lick on tiff . properties . media .check your alpha channel choose premultiply or pre multi dirty for tiff and straight for png

I' don't think I understand what you are saying. I cannot import TIFs into the media bin (and therefore can't change the properties) unless I resize them. Having done that, there doesn't seem to be any need to deal with the alpha channel.
