The Window Sill Observatory

Dave’s Video Stabiliser (DVS)

Dave’s Video Stabiliser (DVS) allows you to create time-lapse animations from a series of still frames such as solar prominence eruptions, Jupiter rotations or comet movement. It removes any frame-to-frame jitter so that your animations are rock steady.

It can also be used to add text or graphic overlays to single images or image sequences.

The current features include

  • Single application covers Windows XP, Vista, 7 (both 32 and 64 bit versions)
  • Import PNG, TIFF, BMP, JPG, GIF
  • Imported frames can be different sizes
  • Optional manual alignment of any frame
  • Crop to region of interest
  • Export as AVI video with adjustable framerate
  • Export to image sequence (PNG)
  • Pixel or sub-pixel alignment
  • Text overlays with selectable font, size and color
  • Graphic overlays (including images with transparent alpha channel)
  • All overlays can have adjustable mark-in and mark-out points to control their visibility
  • Support for multi-core processors
  • NEW! Add timestamps to each frame (UT or local time)
  • NEW!! Astrometry module – see here.

DVS was released in February 2012 and is available as a free public demo in the Support and Downloads page.

Below is a video that shows an unaligned time-lapse animation of a solar feature. It then shows the effects of DVS alignment to the nearest pixel, 1/2 pixel and 1/3 pixel. It also shows several text and graphics overlays with differing mark-in and out points.



  1. I’ve just started using your software, managed to capture and create an animation with it – Thanks for taking the time to write it 🙂

    Animation can be seen here>><&lt; or on SGL 🙂 Also added Windowsill Observatory to my links section!

    Cheers, Ant
