Glad you have the colour issue sorted now. By doing nothing with the defaults a TIF file will be saved from Autostaakert.
As to quality, this is worth a read
https://www.astrokraai.nl/software/Sky% ... 072%5D.pdf. In this document, written by Emil Kraaikamp, Autostakkert Developer, it is stated "typically anything below the horizontal 50% quality line can be ignored" (page 70, left column, last paragraph). That leaves you stacking around 3% of frames captured for the example video if you want to use 75% or better quality. You can stack up to 4 different percentage of frames at 1 pass.
You have the combination of a 6SE scope, 2x Barlow and bad upper atmospheric conditions. From your capture settings file I see figures which are typical of those I have used. Using the Barlow forces an increase in exposure which then lowers the frames per second. Removing the Barlow decreases the image size but increases the frame rate.
Getting the log histogram in the classic 'whale' shape for a given gain is the best indicator of good capture settings.

The atmosphere can vary wildly over minutes e.g. some turbulence or very thin cloud. Over the last 3 or 4 years, Jupiter has been low elevation for me (~25°) and in the Celestron C8 SCT it looked like it was being boiled. Where I live it is not uncommon to see clouds moving from the east and the west - when the two weather fronts meet the atmosphere is unsettled. To counter this, I take multiple SER captures one after the other. These are easy to process - select all the SER files and drag and drop onto the Autostaakert Open button, run through the first and the rest of the videos will be processed using the same settings.
The best planetary images on Astrobin tend to be captured using Celestron C14 or C11 scopes and the capture locations need to be noted. Damian Peach produces excellent planetary images but a 1m scope, 3000m up a mountain does help
http://www.damianpeach.com/picdumidi2017.htm. Damian Peach is second from the left, Emil Kraaikamp (Autostaakert developer) is second from the right. I learnt most of my imaging by attending Damian's 6 hour planetary and lunar workshops.
1 minute videos for Jupiter is good. The fast rotation causes longer videos to 'smear' the detail. As @Altocumulus stated - WinJupos de-rotation software is the answer. There are
(hotly debated) 'guidelines' for maximum video captures of the planets and maximum video time. Some typical figures are:

That should give you enough reading material for a while.

3 minute's a good compromise, but then you're starting to look at de-rotating in winjupos (another ball game to consider!)
