Creating Video Timeline from accelerated playback

Can anyone help me achieve my goal? Is it possible to record my accelerated playback from the action panel and automatically convert it into a video animation to "create video timeline"? This would be similar to a screen recording, but I hope If I could record directly within Photoshop, I would be able to export the created video with a transparent background. If this isn't straightforward, is there a plugin or another method that can achieve this?

I’m aware that using a green screen as a background is an alternative, but if my creation has areas of transparency, removing the green can be very challenging and time consuming.
