Sadly we have to limit how many scenes you can have in a video 😢. For 1.0, the limit is 100 scenes as it can take way way too long to build and time-out after that. As for 3.0, we recommend making your project up to 3 minutes long for the same reason.
We also find that a lot of uploaded content, particularly videos can slow or even stop your video from building. So if you're finding this is the case, contact us and we'll check into the reason for you and help you out.
Extra tip for you: now that you know how long a Biteable video can be, you might wonder how long should your video be for maximum punch! Here’s an interesting article on Hubspot that recommends different video lengths for popular platforms.
