# Blender 3D: Noob to Pro/Using the sequencer to compile frames into an animation

## Preamble

When you render an animation, often it\'s a good idea to render the
individual frames and then compile them into the animation. This has
several benefits over rendering directly to a movie file. Some of them
are these:

-   -   If you discover a mistake in the render, you can modify sections
        of the animation and rerender those frames without having to
        rerender the whole animation.
    -   If the render crashes because the power went out or, (psst),
        blender crashed, you can pick up the render at the last rendered
        frame without having to rerender the whole animation

## Tutorial

-   Open your animation in blender

Begin by opening blender to an animation that is ready to be rendered.

-   If you don\'t have one and don\'t want to wait to long, just
    download the demo file from blender.org For
    You

```{=html}
<!-- -->
```
-   The output format should stay PNG. Though you can use any image
    format you want, I recommend PNG because it is lossless format.

```{=html}
<!-- -->
```
-   Set the file output location.

Set the location on your file system where you want all the frames to be
saved to.

-   Set Endframe to match the animation

If you animated 500 frames, set the end frame to that same number. the
default is 250.

-   Render the animation!

Simply press the \"Render\" button under the render tab.

-   For \"For You\", you only need to click Num0 and go to \"Render\" in
    the menu bar. Then click on \"OpenGL Render Animation\". For
    exercise, 100 frames must be enough.

## Use the Sequencer to compile the images into a movie file

-   Open a new blender and delete everything except the camera.

```{=html}
<!-- -->
```
-   Change the 3d window into the \"Video Sequencer Editor\" window.

!video Sequence

-   Add the images to the sequencer.

On the bottom of the sequencer window click Add\>\>Image then browse to
the location where you saved the images, Press A to select all the
images and finally press "Add Image Strip\" on the top-right.

-   Set final movie format.
-   Set the location that the movie will be saved to by changing the
    output path.

-   Render!

Just Press the Render \"Animation\" button and wait a few seconds till
it\'s done. Browse to the location you saved your movie and enjoy the
animation.
