I'm converting a bunch of old Flash animations to HD video. To do so, I first resize the stage canvas from 550px width to 1920px and also adjust stage height sufficiently (to eventually paste on to a new HD canvas of 1920px X 1080px). In doing so, I'm struggling to find a tidy way to scale up my old Flash animations. as it's difficult to select all frames (including keyframes) to scale them up and reposition as required.
Is there a knack to doing this? Any tips?
From Modify menu, you can choose Document Settings.
Make sure you check 'Scale content'
If your files have a 4:3 ratio and you want to go to 16:9 just do the width first with scaling 'on' and then you will need to crop them in a second pass (scaling 'off'). That will mean chopping a strip at the top and bottom of your stage.
For more precision, you can nest everything inside a Graphic Symbol, using Timeline Block To Symbol or manually.
Working on the Main Timeline is not a good practice and this is only one situation that can be easily avoided if files were set up properly from the beginning.
Hope this helps!
Thanks Nick, that's helfpul.
