How do you convert a video into an Adobe Flash file or if I cant how can I put a gif into an Adobe Flash file and add sound?
If the video is a supported file format, from Flash, choose File
> Import > Video and follow the prompts. There you can either
embed the video directly into the file or load it as an external
file. Once you have imported the video, drag it from the library
onto the stage. If your video is not a supported file format, you
will have to convert it first. Most likely, your copy of Flash came
with Adobe Media Encoder, which you can use to convert your video
file. I recommend using FLV or F4V for the best Flash support.
