Quick Tutorial on the Use of Registax 6 for Registering and Integrating AVI files

These are very tentative procedures. I have not tested the software thoroughly, but these should get you started. There appears to be no need to first create a Registered video. The procedures Align the video first before asking for the Integrated AVI parameters. I went with the default values for the most part. The only change that is required is to change the Framerate as mentioned below.
1. Select Choose the AVI file you want to analyze. If the file doesn’t open, try opening the
file in VirtualDub and re-saving as an AVI file with a new name.
2. Set alignpoints Choose 1 or more alignment stars by right-clicking on each one. Use fairly bright
stars. To undo an alignment star, left-click it. For now, leave all the default
settings as they are. On most videos, one star should be fine. I understand that
the program has the ability to “de-rotate” a video. I haven’t tried that.
2a. De-Rotate ? Select the Estimate Rotation box. Choose at least 2 stars for alignment that are
widely spaced across the video frame. Registax 6 will de-rotate the video so all
field stars stay fixed. This will mean that any time stamps will not work in
LiMovie. This feature is specifically designed for alt-az videos.
3. Align Select Align. Registax will now go through and align the video using the star(s)
you selected. When done, you should see at the bottom that all your frames were
included (the frame counter should show all frames used and the slider at
the bottom should be all the way to the right). If not, move the slider below all
the way to the right manually..
4. Limit Click Limit. This causes Registax to use all the video frames. When done, you
should see a video frame showing the amount of alignment shift. This new
Window will have the AVI file choices at the lower left side.
5. Frame Rate Be sure the Frame Rate is set to “30” for NTSC videos.
6. Save Integrated Select the number of frames to be integrated and, when prompted, give the file
a name. Be descriptive in the name so that you know how the file was created.
7. Analysis The video should now be ready for analysis with LiMovie and/or Tangra.
