problem on converting SWF to MP4 while using camera tool

Is there a reason you can just export as a video to media encoder to make it a mp4?

Hi mate,

Swivel is an old piece of software and it does not recognise the new features of Animate (such as camera).

To export your camera, open your FLA in Animate and use Animate's video export or render your animation to a PNG sequence and then produce a video out of that in Premiere, AE or similar.
