Here are the file types that can be rendered

  • bmp - Bitmap
  • dv - digital video
  • mpg - Motion Picture Expert Group file format for moving pictures
  • gif - graphic interchange format
  • imagemagick - image manipulation program
  • jpeg - Joint Photographic Expert Group - still format suited to photographs
  • libav - libavcodec is a free software/open source LGPL-licensed library of codecs for encoding and decoding video and audio data; it is written in the C programming language. It is part of the FFmpeg-project and many free/open source applications rely on it.
  • null - Dummy file for rendering engine testing?
  • null-tile - Dummy file for rendering engine testing?
  • open-exr - Still image designed for handling Motion picture frames developed by ILM
  • png - portable Network graphics - still images with lossless compression
  • ppm - portable pixmap - still image using very basic format
  • yuv420p - Still image format designed to preserve the images luminance

Rendering to Video

Rendering to video directly from Synfig under Windows presents some challenges.

If you want to render to anything other than mpg with ffmpeg, you'll want to save a series of images that represent your animation, to a still format that ffmpeg can read. I recommend png. Whilst you can render to any size image, if you're going to show your video on Youtube*.mpg->, you may want to take that into account when you render.

If you set up your render like Render.png

Image size - width 320 Xres 72.0 Phys width 4.44 Height 240 Yres 72.0 Phys Height 3.33 (Image span 11.0127

Image area Top left X: -3.67 Y:4.2 Bottom right X: 3.67 y:-4.2)

You will get a series of png files in your output directory. Open a command prompt, cd to that directory, then use ffmpeg to assemble these png files into the video stream of your choice. for example -

C:\output>ffmpeg -r 15 -i rfrac%04d.png -f flv fractal.flv

creates a Flash video file of with the same framerate as used on Youtube. You should be able to submit it to Youtube without the need for the Youtube servers to have to re-compress it.
