Thanks for all the replies.
I am a serious hobbiest, and a computer enthusiast (in that I am a developer).
I am also willing to pay for something that makes life easier long run.
I take about 10 home videos a month, and like to edit them together so i have a few well produced ones, rather than a lot of rubbish ones. Also with smart phone HD video i find a lot of times i want to quickly capture something and put on facebook / youtube.
I have been using AVS, which is paid for, for a long time, and found it really good. video editing is nice, converting is easy, batch conversion etc... it's just that it seems to cut off my mobile device HD video audio after a 30 seconds...
So, i tried premier as a well regarded creative software firm, (have been using photoshop 7 for years now).
All ok on my laptop, although it could not handle AVI files from an old canon camera (Canon MVI01), and produced very dodgy output of my JVC files. a lot of investigation later, and i realise the difference between frame aspect, and pixel aspect, manually told PE10 that my files are 16:9 720x576 (took a while to figure out how the hell that maths worked....) and now it looks good.
however very slow on laptop and no conversion that i could see, (really would like batch).
i then installed on my main PC in my home office, which has more grunt, however it will not launch at all! there is a thread here on adobe site trying to get it sorted
I did notice also on the laptop version now I have gone back to that whilst i wait for a solution that:
1. transition "fade" is not there, and "dip to black" which i would guess is the same, starts with a still of the next video. looks like transition is OUT and not IN to the next scene, however perhaps just my learning curve...
2. the mp4 file i copied from my phone STILL has audio sync problem when played just using preview! same as MOVAVI. this plays fine in windows media player, and in VLC, however even when just double clicking and previewing in APrE10 it is out of sync. so that does not solve my problem.
Either there is something wrong with my file (but it works in vlc/wmp), or both movav and APrE10 (seems unlikely), or some other problem, like codecs?
just really frustrating, i have a couple of clips from holiday on phone I wanted to share on youtube and i just cannot do it without uploading non-edited from the phone...
in any case until PE10 works in windows, i will move on to evaluate the next one. Sony Vegas i think, as i have cyberlink stuff bundled with my optical drives and it is always slow and bloated (the software that came with my blueray player would not play bluerays until i upgraded to the full "pro package" which would have put my £40 br player price up to about £200 !! what a rip off. (anyway, off topic), thanks for the help so far, appreciate it, and if you have any thoughts on my problems with mobile phone content, please let me know. (it's a samsung Gax 2)
