Ziatron you asked
Is there some other video format that can be moved directly into iMovie 06 where it will not go through any conversion process ? I am starting with mp4 video.
I know this is a few months old now, and have probably solved your issue, but thought you might find this interesting.
I believe there is a way of " Importing" ProRes 422 into iMovie HD 6 without going through a conversion process.
As you are probably aware ProRes 422 can be imported into iMovie '09 and '11 if you have the ProRess 422 codec installed on your Mac.
This is usually achieved by having Final Cut Studio 2 or 3 installed.There are other ways of having these codecs installed , but am not sure of the details.
As I have FC Studio 2, then I have the ProRes 422 codec along with others.
This is how you get the ProRes 422 clips into iMovie HD6, without conversion.
Create a new iMovie 6 project.Choose a video format,DV,DV widescreen,HDV 1080i,HDV 720p, etc.
I chose HDV 1080i, as my ProRes files were 1080i.Save to desk-top,select create, then close and quit iMovie 6.
Now control click on the project on the desk-top and Show Package Contents.
Now drag the ProRess files into the Media Folder.Close
Now double click on the iMovie 6 project to open it and select View Trash.
You will see the ProRes files here which you should now drag into the import windows to the right.
Thats it. The ProRes are not converted into AIC.Now you can edit.
I am not sure what would happen if you try this with the mp4 video you had.
I have done a simple test with ProRes as above with a few transitions and titles and it seems OK, then exported as ProRes.
You can then use this ProRes export in iDVD.
Of course people would say that if you have got FCP 6 or 7 then why would you use iMovie HD6.It's down to choice I guess.
The choice of video format when creating the iMovie 6 project may depend on the files being used, but I haven't experimented much with this.
Thought you might like to experiment.
