Hi Bill,
the accelerator was ON on both pcs.
I Turned it off on the i7 pc and it now works with the graphics accelerator off.
With quality set to max it renders giving double the bitrate and double the file size !
thanks
Bill
Good news! It is doing what I would expect it to do at Max.
On mine, the Panasonic camera menu sets it at 100Mbps for best 4K. File peeping suggests that might vary a little. In Premier Elements both "match source" and "medium, recommended" is also 100Mbps. File peeping shows it might be 109Mbps. Like all editors, it is rendering, not making exact copies. So, there should be some differences.
I think using Max at 200Mbps might be trying to make something out of nothing and is a waste of time. I don't know why the choice is there unless other cameras have some higher bitrate settings.
Relative to Sony Movie Studio and Premier Elements, I tried at Movie Studio once. I kept finding Premiere Elements superior for my needs. I can't find anything it won't do and do well.
There is both a free and advanced online third party training course that will bring anybody up to speed quickly. Reply if you want links.
One more thing! I get points if you mark this correct. Someday, if I get enough points, Adobe might give me access to the entire Creative Cloud and I could learn the "real" Premier Pro.
Good luck and have fun with your new camera!
