what have you broken?
A lot of my videos are done via one of my editing suits. If I have videoed in 4K or higher I then use either "wondershare Filmora" or if that doesn't have what I want I use " Movavi editor plus 2022 "version.
Otherwise for all else I turn to "Adobe Premier Elements" editing suite. They all have a built in rendering program.
So to give you an exact answer I can't do. However your question is a bit vague, if I may politely suggest, as rendering can be several different things, From matching a sound track to a video-smoothing out a video- or using a particular codec to name but a few. then if the latter it depends on the camera/camcorder used. That rhino one was on an old panasonic HC-X900M camcorder I no longer have..
My apology for this next bit and all that own a Sony AX53
If I remember you bought a SonyAX53 camcorder against my strong advice about going for a panasonic camcorder such as my Panasonic HC -X1500. Not trying to rub it in but I do make suggestions based on various things of what a camcorder can and can't do having owned that Sony. That Sony has a 1" sensor so pixelation may show up more???? at least in camcorder terms. this might be what you are referring to . Also the lack of control ,as I mentioned in a previous post, I found so restrictive with that Sony version I P/X it after a very short time. It is ok for what it is and can do but not for more serious videographers. If I remember correctly you said the panasonic HC-X1500 looked too professional
Maybe you might consider doing the same and go P/X like I did. I promise you that you will never regret it
Panasonic HC=X1500 hand held on our trip to Faroe Isle church last year. sorry it is only youtube quality

Or thinking about it maybe the graphics computer card can't handle 4k videos or even your down to your monitor is Not a 4K one
If I don't get back to you for a time we are very soon off to Portugal on yet another fly/cruise. My son will be here holding the fort and looking after our dog
