[HELP] Does resizing a cropped resolution to a higher one cause video quality degradation?

[Lunacy]

Sorry, but what you write about aspect ratios does not make sense to me.
For further details about PAR&Co, reading [INFO] About pixel aspect ratios,.. and the linked articles there might help.
If your source is not properly flagged and hasn't a 1:1 PAR, you should set the 'Input PAR' to the correct values.
If you want the minimal possible distortion, then set the output PAR you aim for and set just the width. (Do not disable 'Auto adjust'.)

Let me see if I can clarify: 
My original source is captured at 720x480, which has a "stretched" 3:2 storage aspect ratio (SAR). What I'm aiming for is to achieve a display aspect ratio (DAR) of 4:3 while also eliminating headswitching and overscan in Hybrid. To do this, I'm cropping the image to 700x472 to remove headswitching and overscan. However, I'm concerned that resizing it to a higher resolution of 704x480 might negatively impact the image quality during rendering. Would resizing to 704x480 still be acceptable, or is there a better approach compared to what I did in my screenshot?

Or to make matters "easier", what values should I enter in the PAR and Picture Resize boxes within the Crop/Resize window to attain a 4:3 Display Aspect Ratio (DAR) considering I've already specified my desired crop dimensions resulting in a crop resolution of 700x472 in the Picture Crop box?
