It is an excellent idea to work on a project in small parts, share each part as a DV-AVI and then collect all of your AVIs into a master project for final mix-down. (You may have to use a different output file if you're assembling your video for a BluRay disc.)
Meantime, make sure that you only edit AVCHD video in a project set up for AVCHD. And ensure that your photos are no larger than 1000x750 pixels (or 2000x1500 if you're working on a BluRay hi-def project) and render as you work.
Thanks for the endorsement on this idea!
While I could likely make it through as one file, it would likely take longer and cause a little frustration than starting a 2nd, especially being at a logical breaking point.
Regarding the note on the photo size, my movie is 16:9, right? (or, should I say - 'right.') These dimensions on the still images would be a 4:3, so wouldn't I want a 16:9 on that too? i.e. 1920x1080? Or, is this to keep it in a more native size format (as it was taken)?
I am fairly certain I selected an AVCHD project from the beginning, where can I check this? Although, if I can't change one it's underway maybe I don't want to know! Under Edit, Project Settings it shows - Editing Mode HD 1080i, Timebase 29.97 - Video frame size 1920x1080 ... is this related to the original project settings?
I typically work, stop and render, work, stop and render ... and save every few minutes in between!
You can see (but not change) your project settings under the Edit menu.
You can only change your project settings when you first start a project. You can not change the settings mid-project.
