Based upon your description, you should use say a black color board instead. Place it on a lower track below the video. Open PiP Designer. Go to Object settings and uncheck the Maintain aspect ratio Resize the color board to cover only the part of the video you want to ‘bloop’ out.

As above,
definately sounds more pip than mask.

Thanks guys....I will give it a go....

btw.....also I had been using Power Director 8 for a long time so the jump to 16 has been a learning curve....but I now don't seem to be able to "split" detected scenes in videos. Previously, after detecting scenes, I have viewed and re-split so that I can drop stuff to cut down large video extracts etc. Everytime I do this, version 16 seems to simply crash after I hit OK at the end....any thoughts???

Sorry - bit of a novice..

The last time I used any scene detection is with dv and pinnacle. Modern camera video already have separate files for each recording that I do so don’t need it in my opinion as I prefer to edit it myself without the need of scene detection to do it for me like on continuous video tape. You have not stated why you use PD16 if PD8 is what you are comfortable with. I believe that there may be users who claim PD8 is compatible with Windows 10.

Let us know what type of video file format you are editing and the version of windows that you are using.
