Thanks Robin. Indeed with a dedicated planetary camera, one minute of video is typically in excess of 3GB. I am just writing a talk for my local society and showing them how Registax and AS!4 both handle a 10GB video file… AS!4 does all the processing in 2 minutes, whilst RegiStax has only aligned 7% of the frames at 25 minutes, and has yet to limit them, and stack them…
I will have to look what the file size is for the lowest compression DSLR video at 60fps.
