Hi Borate,
Thank you very much for your help.
You are right, I had the older version of VP and that was exactly the problem.
I have now installed the new version you linked and when I preview the video it's no longer blurry.
However,
I now have two problems,
First off, my older version was licensed, I had paid for it and this latest version I just installed appears to be the non-commercial version.
Can I update to a paid version? How do I do that? I was warned about this before I installed it, but want to ask if I can licence it from having previously paid on older version.
Second problem,
When I exported my video to YouTube, as soon as the export queuing completed, I got a bug message and it program shut down.
I have reported this bug as prompted, but wanted to mention it to you too.
Before I exported the video, I got a message about cropping the video or auto-sizing, I tried both times and still crashed after exporting,
I still need to experiment with this but please tell me if you have any ideas.
We are almost there now,
Video problem fixed, but cant upload without crashing and want to know if I can upgrade licence to latest version please.
