I'm having real trouble working with the movie files (.avi) from my viosport helmet camera. I have some qu.s as I am trying to put together a video this weekend (some background info is below - please help if you can!):
1. Has anyone worked with the viosport camera videos and edited them successfully?
2. They are labelled as .avi, but are not visible to iMovie 09 (ver 8.0.5). All my other .avi clips have no problem like this - are these videos actually a different format but cloaked as avi?! does this make sense?...
3. iMovie HD was importing them OK, but on some large videos (29min, 672MB) now comes up with an unknown error and fails to import - why? This file had previously imported without a problem.
4. NTSC/PAL - The videos were recorded in PAL, but iMovie HD only opens a new project as NTSC. The 'video format' options when opening a new project does not give the options that the help file says it will (there is no mention of PAL/NTSC next to the various options, only 'DV, DV Widescreen,...'). Can I change it once a project is opened - immediately or with videos imported?
Background:
The videos are saved in iPhoto and open in good quality in Quicktime, but are not visible to iMovie 09 and cannot be imported by any of the normal means that I have tried (file/import, drag and drop,...). I have no prob with my other video files. I have tried opening in HD and exporting as quicktime but the file size increases by many times if done at best quality. Doing this can enable '09 to see the file, but rather than 600MB it would become many Gb! - with lots of clips this is unfeasible to make a video (and even the 'best quality' is not as good as the original!).
This is my first real attempt at compiling a movie - any assistance will be hugely appreciated!
