Hi, I have a mixture of videos i want to add to create single output video. Some from iphone 3gs and others from a Lumix DMC-FT10 (Quicktime MotionJPEG). I notice that they all work in videopad however the transition dont work very well. On the fade, one video doesn't start playing untill the fade has completed or on crossfade the image quality is very pixelated. I assume this is due to trying to transition between differing video formats or the formats being used aren't very suitable (quicktime). I know for example some compressed video formats aren't very suitable for editing because of the way they fill in the (b)etween frames as part of their compression algorithm. What video format should i first convert these videos all too to ensure that videopad is going to be able to edit them optimally ? Comments below would be appreciated. Thanks
