Jagged JPEG output in SWF files

Postby jimC on Tue May 29, 2007 8:21 pm

I'm getting jagged JPEGs in my swf movie, even on the highest output setting and using the original high quality imported JPEG file (not compressing it in the imported graphic's info box).

This is a real problem - my client expects everything to be very clean and sharp looking. It looks beautiful on the stage but when I ouput the file, it looks like absolute garbage. I'll never get paid this way.

I've seen other Flash sites that look beautiful. What do they know that I don't? Is there some kind of post export program I need to send it through? I've been using Flash for several years and frankly, I've seen this problem before. On this job I won't get away with it, though.

I made the best possible files in Photoshop before I imported them.

Thanks for reading my post. I've found that masking the item (in the symbol iteself) with the Bezier pen tool smooths the jagged edges nicely. You need to make the border of the mask just inside the edge of the object you're masking so that it's a little smaller.

There's not much you can do about the inside areas, though. You just need to make the imported graphic the best quality you can and be sure to keep it at 100%. Scaling will make it look really bad in the swf.

Actually, I looked at the other sites I've been using to compare mine with and they show the same jaggedness in certain areas.

It seems to be an inherent limitation of the technology since Flash is, after all, a tool for Web graphics. At 72 ppi you're just not going to have the same resolution as a printed piece. Most people, especially clients(!)don't understand this!

I know someone else created a post in this forum about the same issue, so hopefully they'll see this one.

Thanks!
