Your Adobe Animate file uses a proprietary format called .fla (for “Flash” – Animate’s previous incarnation). This is your working file, with all your layers, frames etc.
In order to view your animation as a self-contained Quicktime video file (the format required to upload to YouTube, Vimeo etc.) you must export it. Note that all your layers (even hidden ones will appear in the exported version). Consider creating another version of the file before deleting layers.
To create Quicktime version of your animation:
- Go to File > Export > Export Video…
- The Render sizeshould be the same as your Stage/HD
- Ignore stage color and Convert video in Adobe Media Encoder can be left unchecked
- Stop exportingshould be set to When last frame is reached
- Select the location where you want the exported file to be saved by clicking on the Browsebutton
- Press the Export button
