Hello
I am facing a challenge in a coming job on a documentary film, a part from erasing people and corrections, I am asked to (make that person) sharper in shots, where the out of focus went off the subject. I am aware if I have some sharp frames, I can use some MV (mapping) using the details as a first-aid patch to cover, but I am not sure how this will look in the final result.
Is there any other techniques that could be used? AI maybe?

Yikes! How out of focus are they?
I don’t envy you. I can only think of sharpening tools you can try. You should take a look at crok_equalizer
Selectively sharpen different thresholds.

Thanks man, I didn’t know about the equaliser tool, I will give it a try
Do you have access to Nuke 13? You can train a copycat ML tool to do some refocusing.
Hi Andy, I am aware of the copycat capacities, I will see if the production budget will permit me to go to Nuke as a license, since I am already subscribed with Flame. Was hoping though if someone already trained some nodes to be used inside Flame 
I’d luck with TopazAI Sharpen.
It’s originally for stills, but you can feed a tiff sequence and apply the same settings.
Just have an eye on flickering.
They have a 30-day trial i think.
A few weeks ago there was a thread about making a high pass filter. It can also be used a sharpener, although there is no magic that will make an out of focus shot all well again. In any event, if you put a colour correct node between the high pass filter and the linear light comp node, you can adjust the contrast of the high pass filter and it makes a nice sharpener.

Just keep repeating this mantra to your client:
