I have recently bought PTE version 7 and combine video clips taken with my Nikon Coolpix S8000. Some of the clips require adjustments to brightness, contrast and saturation but it seems that this is not possible inside PTE. I have used Windows Movie Maker and brightness is crudely controlled by dragging and dropping an icon onto the file, for a maximum of six times . When right-clicking in PTE there is a way of adjusting the video but I was directed to Windows Media Player. After adjusting the sliders for Brightness, saturation etc I hoped that the changes would be saved but it seems that the adjustments are only for the duration of the slide show;the file in the timeline was unchanged. Have I missed something in my search for a more sophisticated method of adjustment than that of Windows Movie Maker? Also, WMM would not play the soundtrack of imported Nikon .mov files and I needed to download software to convert the file to .avi format. The sound was then present in the video clip but there was loss of quality; a kind of ghostly pixellation. PTE is fine with .mov files but asks if I wish to optimise for better performance.I OK the request and there doesn't seem to be any loss but some videos were taken on bullet train journeys and there is some noticeable buffering and the resultant jerky movement; not too much but very frustrating. In WMM there was no buffering but the quality loss was the downside. It seems that I must compromise between the two conditions and wonder if anyone can suggest the settings that would suit that particular video clip during the train journey. Thanks Ed.
