Rendering and Exporting in Synfig Studio

What is Rendering?

In Synfig, rendering is the process of generating all the frames of the animation - including all those between keyframes (-aka tweening). This process can take some time to complete (-the higher the resolution and the lengthier the animation, the longer the render will take to complete).

In Synfig, rendering is the process of generating all the frames of the animation - including all those between keyframes..

Due to the time required to carry out a render, it is normally only done at key points, once a section of animation is complete.

Rendering your Project

Once you have completed your project - and it looks good in the preview - click on the caret icon and choose the following option:

File → Render:

The render option

A dialogue box will open up, allowing you to specify various options for the render process. In the top half of the screen are the main two options that you will want to change - notably:

  • Quality: use a value of 1 for the best quality (-or higher values for quicker renders when drafting)
  • Anti-aliasing: Synfig recommends a maximum value of 3 for best results

In the bottom half of the dialogue are a number of tabs. By default, the Image tab is displayed -and this allows you to adjust the canvas size and image attributes of the render (-these will default to your original settings, which are normally what you require anyway):

The Render Properties Dialogue

If you click on the Time tab, you can opt to render just a subset of the whole animation by specifying a start and end time; you can also adjust the frame rate (fps), to make your animation smoother or more compact:

If you click on the Other tab, you can tweak some other, rather esoteric, parameters - but these are not normally something that beginners will need to touch:

Click on the "Render" button to begin the process. A message is displayed at the bottom of the Canvas whilst the process is running but you can continue to use Synfig whilst it is progressing, as the work is all done in the background:

Rendering in Progress

The render process will create one file per frame of animation. That means that if you have a 5 second animation - at a frame rate of 24fps - a total of 24 * 5 = 120 files will be created. Each filename will include a numeric frame number:

These files can then be imported into KDEnlive - just like a manual frame by frame animation - by selecting the "Import image sequence" checkbox:

Saving your Animation

As with all computer work, you should save your work regularly. Synfig is a pretty robust program - but the nature of computer RAM is volatile, so we would recommend frequent saving at key points in your development process.

To save your animation, simply select:

File → Save As:

A dialogue box will open up allowing you to specify the filename and location for the file:

Exiting Synfig Studio

To exit Synfig, simply click the caret icon and choose the option:

File → Quit:
