Having trouble removing ads without encoding

I am trying to remove ads from an episode of family guy i got using playon from my hulu account.

the issue im having is after it encodes it to a mp4 at 1920, the episode looks fuzzy during movement of the characters.

this slight fuzz is not there in the original 720 playon file.

the ad removal works great and i was wondering if i can by pass the encoding part? afterall its not changing the format, its going from mp4 to mp4 so its pointless.

now, i am using the free trial as i needed to know if it would do what it was said to do, and is it because im trying to encode a 720 to a 1920?

any advice would be very helpful before i start the long process of trying to remove the ads from my dvr recordings. thank you in advance

Use the Unprocessed profiles, it retains the original video and audio without recoding.
