Are you on a Mac or PC? If on a Mac, there is a great utility called 5DtoRGB Batch which converts from h.264 to ProRes which is 10 bit. You're just taking an 8 bit file and putting into a 10 bit container, but the video is still 8bit. Your benefit comes in when you do a lot of post processing. Any banding issues in the 8bit video won't magically go way once converted to 10bit.

thanks, however I'm on PC, seems like 5DtoRGB is only for mac.
Meanwhile I found out that Adobe kinda come with Cineform itself. By using the Gopro Cineform codec Quality 5 is equivalent to Film Scan 2. I put my files in my timeline and with the project manager they will output 10 or 12 bits files.
The bandings issue won't likely to be fully resolved, but it could be greatly reduced with filters which is one benefits of this technique by using neat video and noise filters. I already did few tests and I had some convincing results.
Only I have to do this on every clips because Lumetri filters seems to not like at all 8 bits footage or there will be huge artifacts. I don't know if there's a way in Premiere to make a batch with filter applied, that would speed up the process.
