I'm working on a video project that I'm mastering in 1080p 23.976 fps. The flash project will be in the same format to begin with (so an animation can be included in the video). Along with outputting the project as an mp4 file, I also need to output it as an swf I can put on a website. Obviously 1080 is way too big for the web.
So what I need to know is if I can convert project size within Flash after I finish the project, or if I need to do it in another program. I would prefer to do this as efficiently as possible to maintain functionality.
Not sure I'm following exactly. So, this answer might not be addressing your question.
There's no way in Flash to export at any other size than the size of the fla doc. ( Not referring to scaling, or extending of the stage. ) This is in referring to the Flash authoring application. Encoding video into a format which can play in the Flash player, that though is a different story. That can be done at any size you want.
Thanks Justin, that's exactly what I wanted to know. So it looks like I need to make separate flash projects in order to have one file that fits inside the video and one that will work on the web. I hope I can do that by throwing the objects I use into the library so I don't have to remake them for each project : P
