If you plan to record lengthy screencasts in Articulate Storyline, you’ll need a powerful computer that can process large video files. And be aware that it may take a very long time to process. We recommend multiple smaller screencasts rather than one long screencast.
Storyline lets you record up to two hours for a single recording. However, not all computers are equipped to process such a lengthy video. It's best to record smaller chunks to avoid processing issues and learner fatigue.
