Specific Settings for Videos

Available in: Matter: Snapshot > Snapshot Video

Videos exports a timeline as a sequence of frames in a video file. This editor allows you to specify all of the parameters for the conversion of your real-time animation to a frame-based video format that can be saved to your computer and read by common video players.

From Videos, you can set the parameters for the conversion from real-time to video file:

  • The dimensions,

  • The video format, including file name, file extension, codec, and compression,

  • The rendering engine to use,

  • The timeline that will provide the animation, and the frame rate to apply,

  • The frames to include in the video file,

  • A preview of the frames that will be created.

Once all of the parameters have been defined, click the Render button to launch the rendering of each frame and the production of the video file.

Tip

During rendering, a dialogue box is displayed to show the progression of the creation of the video file. The Viewer button at the bottom of this dialogue box opens a frame viewing window.

At any time, you can pause the progression by clicking the Pause button, or cancel it by clicking the Cancel button. If you have paused the rendering, start it again by clicking on Resume.

Dimensions Zone

The dimensions of the animation to be rendered are filled out in the Dimensions box.

The Format drop-down lists the most common sizes and formats. Some, such as User-Defined, allow you to directly set the dimension values. By default, the format Defined by Viewport is proposed.

Files Zone

Video formats are defined by three parameters:

  • Container (file format),

  • Codec (encoding algorithm),

  • Bitrate (encoding quality).

When the container is changed, the codecs available in the drop-down list are updated according to the codecs supported by the format.

The available containers (formats) are the following:

  • AVI (Audio / Video Interleaved) ;

  • MKV (Matrovska Video) ;

  • FLV (Flash Video).

Each video format can embed different encoding algorithms called codecs. Some of them are specific to a format. For example, only Sorenson codec is available for FLV format. Check the documentation of your movie processing software to known which format and codec best fit your needs.

The bitrate defines the amount of data stored to represent the frames. A low value will generate a small-sized file, but visual quality will be low. Conversely, a high value will generate a good quality video but the file will be larger.

Timeline Zone

The Timeline zone provides the Timeline drop-down list from which you can choose the timeline to be rendered as a video.

Next to the timeline selection, specify the frame rate for the conversion from real-time animation to frame-based video.

Frame Output Zone

You have the option to render only a portion of the timeline range by providing the numbers of the desired frames:

  • Current Frame,

  • All Frames,

  • A Range of frames.

It is also possible to indicate the initial number for the index appended to the filename of each frame in the Output Filename zone. By default, the value of this option is "0."

Preview

The Preview zone provides a preview of each of the frames that will be rendered.

You can move within the preview sequence:

  • By using the buttons to step backwards (<) and forwards (>) one frame at a time in the sequence,

  • By providing a frame number,

  • By sliding the cursor along the bar.

You can also visualize the sequence by using the Play and Stop buttons. The frame sequence playback is displayed in the current active viewport.

Tick the Loop checkbox to play the video preview in a loop.

Note

The editors Videos and Timelines both use the active viewport to display playback. Consequently, you cannot view playback from both editors at the same time.

If the real-time playback in Timelines is playing, you will not be able to play the video preview. Use the controls in the Timelines to pause the real-time playback before playing the video preview.

Conversely, if the video preview is playing, you must stop it in Videos before running real-time playback from Timelines.
