I will try and give as much information as possible.
I bought a cheap video camera, i know the worst kind but was so i didnt mind it getting hit, a little while ago.
It has been filming fine and edited it on my old laptop using Windows Movie Maker.
For the cost of the camera and the software I was using I was quite happy.
I decided to buy a new desktop PC to help editing the video as the laptop was on its last legs.
At the same time I have decided I want to get some better software.
I downloaded Adobe Premier Elements 10 and Sony Vegas Movie Studio HD Platinum 11 trials to see what they were like.
Now comes the problem.
Using Quicktime, Windows Movie maker, VideoImpression 2 and even Adobe Organiser the videos play fine.
When I use the better programs however, the audio plays fine but I only get brief flashes of video.
Using the Movie Inspector mode in Quicktime I have found out that they are in "Motion JPEG OpenDML" format.
I will be honest in saying that I dont know a great deal about computer software and even less about video editing.
I have tried downloading various codecs and codec packs but have had no luck.
If anyone can give me any advice or help it would be greatly appreciated.
