How to Find Missing Frames in an Image Sequence

How to Find Missing Frames in an Image Sequence with a JavaScript Applet on Mac OS X

When network rendering with software like LightWave 3D, modo, Blender or others we often wind up with missing frames. I’m often asked how to find missing frames in an image sequence. DreamLight Constellation has an option to find missing frames in an image sequence and render only missing frames. In preparation of enhancing that feature to include finding missing frames from render buffer exports in LightWave 3D 2018, I wrote a little JavaScript applet in Apple’s Script Editor to quickly find missing frames in any numbered image sequence.

I figured I’d release a standalone JavaScript applet for use until I have a chance to add a cross-platform implementation into a future update of DreamLight Constellation. Michael Scaramozzino and DreamLight Incorporated make no warranties whatsoever regarding this script applet. USE AT YOUR OWN RISK!

1. Download the JavaScript applet.

2. Drag a numbered frame file from an image sequence onto the JavaScript applet.
   
   
3. Click OK to copy the missing frame range(s) to the clipboard. Then paste the arbitrary range(s) into LightWave 3D or DreamLight Constellation to render the missing frames.
