An MP4 file is a compressed file. When your AVS editor renders it, it’s compressing the output file again, causing the loss of definition.
As with Mike, I’m not familiar with AVS but read over the manual and see if there’s a setting that will not re-compress a rendered file. For example, in Premiere Pro, the export routine has a setting that determines the final size of the finished file and that’s what determines how much or how little compression is applied.
After checking the AVS website, it seems they have an editing application that does not re-compress the files called AVS Video Remaker. You might want to have a look at that.
