you should consider more conventional ways to reduce your swf's size. (and it is the swf that's 1.8 mb, correct?)
first, what do you mean by "..i tried an swf and flv file"? do you have video embedded in your current swf? if there audio? are there images in your swf?
Let me be more conside. created a document at 800 X 600 px. There is audio and pictures. No embedded video. The flash presentation runs about 4 minutes. The .fla file is about 9mb. I am trying to get the file size down so I can put it on a website. When I convert it to a swf file the file size goes down but is still 1.8mb. Much too large for viewing on a site. How do you take the native size of the document as a whole, the 800 X 600 and reduce that size, thus reducing the final output on web?
remove your images from your fla and load them when needed. remove the audio from your fla and load it when needed.
I do not think you understand the question. Here is an answer I got off another forum but do not quite understand how to implement.
If you want to resize everything, a quicker way would be to select all frames (select the onion skin tool) and then resize everything to fit the new canvas size. That way, every frame of your animation will be reduced at once.
Does that make sense? How do you get the onion skin to select every frame in the animation?
Resizing the Flash file isn't going to save you very much. What usually drives the size of the file is the weight of the imported content it holds. Most of the weight is usually due to images, sound, and video files.
You can resize/optimize your images before importing them to realize some savings. Changing their size after their imported isn't going to reduce the file weight they add.
Another thing you might try, if you haven't done this yet... select Save and Compact the next time you save it. This removes memories of the past that can add unnecessary weight to a file.
