<"I uploaded the processed JPEG file from another AVI video with a longer exposure time of 591ms and a lower gain of 16 to reduce noise in image.">
First, don't use jpeg files out of AS!3 - they are only for posting images to be clear, output .tifs from AS!3.
Second, an exposure time of 591ms is less than 2 frames per second & a gain of "16" is ridiculously low...I'm assuming you're using the ASI120MC camera & using FireCapture for image capture..?
With exp. 591ms & gain "16" you are making things far too difficult - exposure determines fps (frame-rate) & as an example 10ms = 100fps...20ms = 50fps etc but you also need to adjust the ROI (region of interest) to enable faster frame-rates. Specifically the "height" of any ROI you select but capture in avi format (8 bit) & have the "High Speed" checked under the "More" tab's dropdown menu.
The gain determines the histogram you set - a bit confusing when a lot of people think exposure = histogram but you aim for a histogram of about 60%+ with the ASI120MC because it doesn't like going too much below this because artefacts "can" occur if you do.
<"I thought that the PIPP app was to align all the individual frames in a video so that you don’t get this problem. Could that possibly be the problem?">
AS!3 is perfectly capable of doing this without PIPP - PIPP is really only useful imo if you have a lot of frames during the capture where the planet is half off the capture screen etc, as when you image in very windy situations. But used correctly PIPP before AS!3 shouldn't cause problems, just unnecessary most of the time!
<"Here is an image after post processing by using Kokatha Man’s suggestions from a previous post that he mentioned earlier in this post for processing Saturn. I’m also uploading a screenshot of the MAP’s of how I placed them according to his suggestions.">
Unfortunately I cannot see from you images what size you set the AP's at - I can see that you drew 2 like I tried to demonstrate but taking into account the size of your image the AP's you placed on the rings etc are still outside those 2 drawn ones at the top.
The "non-drawn" AP's are also far too big for the size of the image...in my example the size of the planet is the capture size...in your smaller image you have to scale down the AP size & make the 2 drawn ones at the end of my example encompass all these as per my images & text.
You're also not equally-spacing those you've placed along the rings, some places are missing an AP & they are not regularly placed along the rings as well...
Before you place the AP's on the planet in AS!3 you really should run the "Analyse" stage of AS!3 to get a quality-ordered sequence - your image is blurry & by "Analysing" first you can use the first frame in the series which should be the sharpest/clearest to place AP's on...it is not necessary to place the AP's before you run the "Analyse" stage of AS!3 btw..!
<"If you zoom in on the image you can see a ghost of rings super imposed on each other at different angles.........................................................I’m not sure if this is all due to bad seeing conditions or my poor post processing but I think it’s the former.">
Collimation, poor focus & poor seeing are all very likely problems unfortunately; the ploy of placing AP's along the entire ring (as per how I demonstrated) can sometimes alleviate the split Cassini Division at the ansae (ends) of the rings in certain seeing conditions, but it is far from foolproof - collimation & focus also require a minimum of decent seeing to be able to be obtained also.
