I don't think, that you will get acceptable results. I don't know the photo effect, that allows a 200% zoom and just softens the edges and let the photo still clear.
Whats not in the picture or a video clip, you will not get it by post production.
Every (non optical) zooming and almost every filter makes a videoclip worse.
I don't recommend dashcams. They do not have a good quality by design. They are made for taking long shots. Not the quality is important, but the length of the produced clip. Better use cheap actioncams. Even better: Let some children do the job with the mobile phones from their parents. Really better: use cheap compact cameras.
Do it the best quality. If you have 4K or 4K-light or 2.7K, use it. If you have to stabilize the footage (and you will have to), you always have to zoom in.
But to answer your question:
1. You can play with BCC Beauty Studio (PowerDirector 16 Ultimate):

2. You can split your clip into a picture sequence. Maybe you can use the filter, that you mentioned, on every picture by a batch process.
