Most of last night was lost to cloud. There was a slight clearance just before the dawn that revealed this magnificent display. Still compromised by the weather though. www.youtube.com/watch?v=nsX4z-MRxUU
Hi Bill, I record it using a Canon EOS 600D. The movie record size is 1920 x 1080 and 25 frames a second, but...by adding the free Magic Lantern software to the card I can slow the frame capture rate to 1 frame per second. This creates a timelapse on playback. I load the file into the free version of 'VideoPad' film editor. After any edits required I save it as an AVI file 1920 x 1080 and by clicking on the 'encoder options' I choose the 'Xvid MPEG-4 Codec' and you can also click on the 'Video Compression Settings' to compress it - I usually choose between the '1' to '1.22' setting (highest quality) The short timelapse last night ended up being about 99mb in size and took about 30 minutes to upload. At the moment the Canon EOS 600D is probably the best suited for the Magic Lantern slow frame rate. The 550D starts to complain about the heat. The later versions of the EOS cameras are still experimental. I think the 650D shows black vertical lines on the timelapse. I am a long way from being an expert on these things. I am the 'press this button and hope for the best' type of person. Hope you can make something of this rambling response.
