Thanks, John. It was shot using the in-camera custom white balance, which was done using sintered PTFE as white balance reference. Hence I did not need to adjust this when making the clip in iMovie.
I created an account on Vimeo and uploaded my UV-video of a pair of American Goldfinches on one of my Dad's homemade bird feeders.
The WB seems OK and clearly shows rather striking false UV-yellow especially on the male. The video quality on Vimeo is less than my native file presumably due to how they compress.
Actually, much like flowers that are yellow in visible and also false UV-yellow, these birds have a roughly similar appearance in the visible. I did not collect sufficiently detailed images to be able to discern any Vis/UV differential patterns.
Here is a link to a drawing of how they look which varies with season. Unfortunately the drawing has an error, the right uppermost is a male in winter plumage not a female.
This video was shot with a full-spectrum Olympus EM-5 with my custom-made Insect-D-sight (UV+ blue and green) filter. I used in-camera custom white balance done for this filter to shoot the video. The only post-processing was trimming of clips and adding of titles and music in iMovie.
