As answered by people managing Project Euler and Spectacle.
Spectacle's answer:
Spectacle is unique to other tools because, instead of recording your screen, it captures actions (clicks, form submissions, etc.) and creates a script.
These actions are arranged individually on a timeline to generate your video. This makes it easy to update, add or remove actions, and keep your videos up-to-date.
This was designed specifically with SaaS tutorials and product demos in mind, so when your product changes, you just need to hit re-record and get an updated version. You don’t need to reshoot or start from the beginning.
Spectacle's answer:
This was developed out of a challenge we faced at a previous SaaS company: the constant need to keep tutorial videos current.
The recurring roadblocks we can into doing this included:
No money or resources to create something professional: Free screen recordings always looked cheap.
Spent a lot of money on a video agency: After we had the budget, we hired a fancy design agency to create explainer and tutorial videos. To be fair, the videos looked good. But it was expensive and the collaboration process was time-consuming, especially for one-off videos that weren’t timeless.
Couldn’t maintain videos and our product docs were outdated: After just one product release, these videos were no longer relevant. So despite the help from an agency, we found that we still didn’t have a maintainable or scalable strategy in place.
Spectacle is our solution to creating and maintaining SaaS tutorial and product videos without the hassle or high costs.
Spectacle's answer:
Screen recordings are a great way to teach your users how to use your product and get the most out of it. But creating screen recording videos of your product can be time-consuming. And frustrating. And a pain to do.
Especially if you need to update your documentation often.
Spectacle is a smarter alternative to traditional screen recording videos.
Having the ability to generate updated videos automatically with a single click saves you both time and money.
