If we've only partially render our animation we can just set the start frame value to where we've stopped rendering and then set the end frame value to cover the rest of our animation. The start frame value also cannot go below 0. These frames are the range that Blender will render and we'll need to make sure that the end value covers our whole render. In the Timeline Window as well as the output properties there are two input fields which allow us to input the start and end frames.

We can leave all the options as is for now and head over to the compositing workspace. In the output properties under output click on the file format dropdown and select OpenEXR MultiLayer. Next we'll want to output our frames as multi layer EXR so we can save all of our compositing data and later reimport it. In the path input field click on the file button and navigate to the folder you want to output to. To set the path go to Properties > Output Properties > Output. Outputting an animation with multilayer EXR filesįirst we'll want to specify our file output path if we haven't already. This method also allows for compositing outside of Blender. This method also allows for the separation of rendering and compositing for example if we're working in a team and have someone who specializes in compositing.

The advantage of this method is that if we want to change our compositing setup we can render those changes much quicker since we won't need to render the whole scene again. Render an image sequence first and composite it after renderingĪnother great way to composite an animation is to do all the compositing after we've rendered. This can help cut down on render time as well as file size since we can render everything in one go. When we render all the compositing will be included. This compositing step will also be applied if we were to use our scene as a clip in another scene's video editor. We may also not need nearly as much color depth or accuracy. We can directly output our files in a more compressed format since we won't need multiple layers for compositing later. This method is also great for saving on file size. In properties > output properties > set the output path as well as the format we'd like to useĬompositing at render time can be a lot quicker than outputting an EXR and then having to reimport and composite later.
