Help with Blurry Images in Published File

No matter what format I insert in Powerpoint, when I publish to Breeze the image becomes blurry. I tried multiple image formats, with and without transparency.

Any suggestions?

Thanks for the great replies. Rob, I tried your one suggestion of creating the imagery as a .swf and import that way. Works great. I have a few photo type images and a vector logo that are now crystal clear. But it seems that swf and powerpoint objects on the same slide do not play well when it comes to order or layer order. Oh well.

As a graphic designer and a perfectionist this problem is very disappointing.

[ For what it's worth, one other thing we've noticed about images in PPT is that if things are grouped, they inexplicably get more blurry than if the images were all separate objects to begin with. Not to confuse the issue that Sean mentions, but what I'm suggesting is the following:

Rather than grouping a series of images on a slide, keep everything separate.]

I saw the same issues when jpgs were close together, for sure. This is actually what led us to just make grouped into their own larger jpg.

Thanks for joggin' my memory - this one was a nightmare for me and the client.

No problem Sean!

When I first encountered this problem, it was driving me nuts! Even after changing the quality setting, I still had images that looked like garbage. For me, the problem first occured when I wanted to animate several objects at the same time. But the end result looked terrible. Then I ungrouped them, rebuilt the animation, republished and PRESTO!...everything looked 10x better!

Then, this forced me to rethink a workflow process when handling images, and now I do things quite a bit differently. One thing that seems to have helped is to throw a little bit of sharpening (most of my image editing is done in Photoshop) to the tune of about 50-70% and during the "save for web" process, I set the quality as high as I can get it without creating too huge a file.

If you search around, you'll no doubt find that others have different ways of handling the quality issue. I've tried a couple other techniques that I've read in this forum, but I'm sure it's also going to be tough for some folks especially if you don't have a decent set of tools to work with, such as Photoshop, PSP, Corel, etc.

I have seen this with some of my clients, and as much as we tried to narrow this down, we couldn't. We 1st thought it was PPT, then the OS, then maybe Breeze Presenter 5 vs Presenter 6. We also adjusted the image quality, which by default, is set to medium.

Out of all of this investigation, we found that to get th best results witht he following (and with unsupported reasons, just what we found)
- Use Presenter 6 on high quality image setting
- Don't make the jpg image larger in PPT after you've inserted it. In other words, inserting the image at the exactly same size it was captured.
- if you have multiple jpgs, or images on one slide, take all of the together and make 1 large jpg, then insert them all as 1 file

Hope this helps?

Thanks for the info. I agree this may be the best I can do.

What is strange is if you add a logo or a facilitator photo it does not blur it at all.

HCSG,

What kind of images specifically are you having issues with? Vector based or photographic?

If you're using content comprised of vectors (like artwork created in CorelDraw or Illustrator), you might want to try exporting your graphics in the .wmf format. Objects in that format retain clarity and provide editability if you have the need to go back and modify an object while in the powerpoint environment.

As for photographic content, all I can say is that this has been a sticky issue since Breeze came on the scene. Folks have reported various workaround techinques, and a search through these forums would result in a few topics I'm sure.

One such fix includes converting artwork into .swf format and then importing the flash object into Powerpoint. The only problem I see with that technique is scaling...if you resize the file, you'll end up with more aliasing than you want. In this case, follow Sean's advice: don't make imagery larger than how you initially captured it.

What I can also share, if it helps at all, is a thread between myself and asm0d about this topic as well:

And lastly, there are a number of articles regarding image resolution, size and bit depth when incorporating graphics in PowerPoint...one such article can be found here: http://pptfaq.com/FAQ00415.htm

Hope this helps!
