The video recording did work in a previous version - but only when you where connected to the internet and in low resolution. We used an external platform called “Kamcord” - but they stopped their service - so we had to take the functionality out.
The Tagtool Player works best for recording animations - we are working on the public release for that. The current BETA version is also in development due to the current app update.
External software/hardware might be an option.
