Why we like it

Earns its place in the superhive library as a focused FPS conversion utility that keeps animation timing intact and adds undo and backup options while you experiment.

What is Change Frame Rate?

Change Frame Rate is a Blender add-on for converting the frame rate of a 3D project. Instead of manually calculating time stretch ratios and multiplying frame ranges, you type a new FPS and click Change, and the add-on handles the math, scaling, and scene updates. It works on FPS, time stretching, and frame range together in a single action.

One stated behaviour is that timing is preserved: a 10-second animation stays 10 seconds long regardless of the new FPS you choose. If you change your mind, a smart undo reverts the settings, and a backup system lets you store and restore scene settings while you experiment.

The add-on is integrated into Blender's Output Properties panel and supports Blender versions 3.6 through 5.0, with Cycles and Eevee as the render engines used. It is Blender Extension compatible, released under the GPL license, and the current version is 1.0.1. Documentation is included.

Who is Change Frame Rate best for?

Change Frame Rate is best for blender artists who need to convert a scene's FPS without manually recalculating time stretch ratios and frame ranges.

How much does Change Frame Rate cost?

Change Frame Rate is completely free to download and use.

Frequently asked questions

What Blender versions does Change Frame Rate support?

Change Frame Rate supports Blender versions 3.6 through 5.0 and is listed as Blender Extension compatible. Cycles and Eevee are listed as the render engines used. The current release is version 1.0.1, and the add-on is categorized under Scene Tools and lives in the Output Properties panel. If you're running a Blender release inside that 3.6 to 5.0 range, Change Frame Rate should match your setup.

How does Change Frame Rate keep my animation timing when I convert FPS?

Change Frame Rate preserves the duration of your animation when you convert the frame rate. A 10-second animation stays 10 seconds long regardless of the new FPS you pick. The add-on handles the FPS value, time stretching, and frame range automatically after you type a new FPS and click Change, so you don't calculate time stretch ratios or multiply frame ranges by hand. A smart undo lets you revert the settings if you change your mind.

Where does Change Frame Rate appear in the Blender interface?

Change Frame Rate is integrated directly into Blender's Output Properties panel, which is also listed as its location within the interface. You set your target FPS there and click Change to apply the conversion. Alongside the conversion, the add-on includes a backup system that lets you store and restore scene settings while you experiment, plus a smart undo to roll back changes. Documentation is included to help you get started with the workflow.

Is Change Frame Rate free, and what license does it use?

Change Frame Rate is listed as free in this catalog. For current licensing details, check the developer's page. The add-on is released under the GPL license, and its developer, Vikky3D, is noted as a Blender Development Fund contributor. It was published around six months ago as an add-on categorized under Scene Tools. The developer's page is the best place to confirm any terms before you download.
