Why we like it

Earns its place in the superhive library for a narrow, practical job: it removes the guesswork around the End Frame during real-time keyframe recording, and stays non-destructive while doing it.

What is Realtime Endframe Add-On?

Realtime Endframe Add-On automatically extends the Blender timeline while animation playback is running. It appears as a tab in the Sidebar of the 3D Viewport, the N panel. Clicking Start Recording plays the animation, and when the current frame gets close to the end frame, the add-on pushes the end frame forward, keeping playback going indefinitely.

When you're done, press ESC or click the button again. Playback stops, the final frame is set, and the timeline is trimmed exactly where it needs to be. It's non-destructive, so it doesn't change your Auto Keying settings or previously set keyframes, and no setup is needed since it works instantly out of the box.

It's ideal for recording keyframes in real time, for example with Auto Keying. The developer built it for archviz animations using Walk mode and Auto Keying, to avoid guessing the End Frame in advance. It was made and tested with Blender 4.3 and is distributed under the GPL license.

Who is Realtime Endframe Add-On best for?

Realtime Endframe Add-On is best for recording keyframes in real time with Auto Keying, and archviz animations built with Walk mode where you'd rather not set the End Frame in advance.

Frequently asked questions

Does Realtime Endframe Add-On work with Blender 4.3?

Realtime Endframe Add-On was made and tested with Blender 4.3, according to the developer. It's distributed under the GPL license. If you're on a different Blender release, check the developer's page for confirmation before relying on it in a project, since Blender 4.3 is the version stated for compatibility here. When in doubt, the developer's page is the place to verify support for your setup, since compatibility with other Blender versions isn't stated in the listing.

Where does Realtime Endframe Add-On appear in Blender?

Realtime Endframe Add-On shows up as a tab in the Sidebar of the 3D Viewport, known as the N panel. From there you click the Start Recording button to begin playback. As the current frame approaches the end frame, the add-on pushes the end frame forward, so playback continues indefinitely. When you're finished, press ESC or click the button again to stop playback, set the final frame, and trim the timeline exactly where it needs to be.

Does Realtime Endframe Add-On change my Auto Keying settings or existing keyframes?

Realtime Endframe Add-On is non-destructive. It doesn't change your Auto Keying settings, and it leaves previously set keyframes untouched. It also needs no setup and works instantly out of the box. Its role is limited to extending the timeline during playback by pushing the End Frame forward, then trimming the timeline when you stop. That keeps it safe to drop into an existing scene without reworking how you already have Auto Keying configured.

Is Realtime Endframe Add-On free?

Realtime Endframe Add-On is listed as free in this catalog. Licensing and pricing can change over time, so for the current terms and any purchase details, check the developer's page directly. The add-on is published by FrancescoMilanese and is distributed under the GPL license. Visiting the developer's page is also the best way to find the latest version and any documentation before you install it.
