On this subject , I have just had a fright. When enlarging the preview to full screen the picture quality is just awful. I then checked a same picture against the one I have on WMMaker and Wmm is outstanding. Also checked the original of course - again perfect.
So I did the export to PC file and what a relief, so much better. Not as good as on WMM though for some reason, but as I am still experimenting I have the choice ; WMM - but lacks channels and little can be done with audio, versus VP - which I like the features but a little disappointed at final result. Yes, someone is going to ask what settings i used for the export - and of course I don't know.
I will re-export with "auto match content" for starters as the gentleman above suggests and also note what other settings I use. Thank you for listening, just nice to know others are as interested as me.
