Thanks to Carl for running the workshop session last night, and for finding a solution to The Codec Problem!

But there was one point which I forgot to make - the suggestion that once you've loaded your video sequence and performed all the Alignment and Stacking steps (and maybe the RGB Align too), it's a good idea to Save a copy of the resultant image (in a 16-bit format) before starting any of the later processing (histogram stretch, wavelets, etc.)
Then if you make a mess of the rest of the post-processing, you can easily re-load the "pristine" stacked image, rather than having to waste time going "back to square one" and repeating the alignment and stacking.
And this single image is a lot more compact to archive than the original video stream!
:idea: This also allows you to export the stacked image into other wavelet programs (e.g. IRIS) to compare the results which they can achieve with the same data...

in a 16-bit format

When saving in Registax (or any even IRIS) try and save as a TIFF file. This is the the 16-bit format and contains all the data. The tip is courtesy of Dave Ratledge.

I choose to image with an 11" SCT Celestron in this decade and do the other things, not because they are easy, but because they are hard......
