From the file dropdown - Import previous Pinnacle Studio Projects. I have just imported two projects one from 2006 probably created using PS10 source video 4:3 AVI. The second from 2010 probably created with PS15 source video 1080 m2ts. Some media needed relinking but was otherwise ok. Audio is split from the video, so if making any adjustments ...

Wasted a lot of time trying to fix this. A reinstall of W10 fixed it. 

Initially when I installed refocus the version was 210712 this updated to 211005. I have uninstalled (via Windows), this removes the filters from PS23, 24 and 25. I have reinstalled the problem is still with PS25. I am currently trying a PS25 repair.

Only the filters section

Unfortunately suggestion has not helped.

Should have been fixed by now!

Having decided to update to PS25, the NewBlue Filters 5 Refocus, (which came as freebie) do not seem to integrate into PS25 but seem at home in PS23, PS24. Any ideas?

This patch has fixed the jumpy stuttering playback that the 24.1 patch introduced.  

Link to sample now posted. Take a look at Orbryn Stevensons comment 13 Aug 2020 editors forum. 

Configuration: signal generator connected via line in to camera. 2 clips recorded, one mp4, one m2ts. PS22 and earlier both have same audio level. PS23/24 the m2ts clip has 12dB uplift.  link to files:   Download link ...
