reason for this is because i wanted to upload the finish product to youtube i did the background animation design in flash and wanted to import the two videos which would be playing at the same time... in the end i had to export the background scene From Flash and import everything to Adobe Premiere it isn't exactly how i wanted it to be but at least i got it done. however i can't shake the feeling that there's a much more easier way of doing this.
these are the supported youtube formats:
and, of those, only mov and avi can be exported from flash pro. those exports are usually unsatisfactory because flash pro is not a video editing program. ie, you are using the wrong tool for the job.
check adobe premiere.
