Here’s how I do it.
PAL 16:9 displays using rectangular pixels at 720×576. unfortunately Flash uses square pixels so you will need to set up your Flash stage slightly wider than the video 1024×576.
I export the video in three ways.
1) Set your publish settings to Flash 5 and select the Formats tab and check the Qucktime with Flash Track (.mov) radio button to export the video directly. Unfortuantely this method only supports Flash 5 graphical elements for not funky line strokes or filter effects show up. – I was reading an article that explained that this doesn’t actually create a video file – it embeds the Flash movie inside a quicktime.mov
2) Goto File > Export > Export Movie > Then select PNG sequence from tdrop down Format box. – You then use After Effects or some such video program to import the series of images as frames of a video project – easy.
3) If you’re on a Mac you get to export Quicktime directly – this supports later versions of Flash so – you can use your strok effects and filters after all!
The last two options seems to work best for me – personally the third option seems to be the best at dealing with more complex Flash animations. If you don’t have a mac – option 2 is your best bet.
Set up a project in After Effects whos export setting are set to PAL 16:9 High Quality 720×576 Next you open your quicktime.mov or .png sequence in After Effects and export out a new quicktime.mov file – hey presto rectangular pixels!! Unfortuantely the file will look rubbish on your monitor because your monitor uses square pixels but once you get the Flash into a video compositing application like Final Cut Pro or Avid Xpress it will ping back to clarity suitable for broadcasting.
Tips: Be aware that until we all go digital, which is still a couple of years away TVs are rubbish. They display substantially less information than a monitor and their gamut of colours is much smaller. Broadcast Safe Colours are as follows:
RGB between 16 and 235
Pure white= 235,235,235
Pure black= 16,16,16
