I export the finished

project back out to the camcorder. I also burn a standard def DVD...

Then, at the point I get a BluRay or HD-DVD burner connected to my 'puter, I import from the camcorder to the 'puter and into that HD format...

BUT, I use a miniDV based 1080i camcorder, so this is easy to do and archiving digital tape is a good long-term safe storage strategy...

so... I saw your earlier post, but you are not in the miniDV

tape environment, so my solution does not apply.

I expect that you would export the finished project back out to SD card(s) - but that will get expensive. Oh well... I guess that is another downside of using memory card-based systems... as has been noted here several times.

Here's a question
by Dan Filice / November 5, 2007 8:45 AM PST

My Mac uses iMovieHD, which means I can import HD footage, edit, then output back to an HD camcorder. This means in theory, I can edit HD content and watch it in HD if I connect my HD camcorder directly to the TV. But here's the question: iMovie stores it's media files in a folder, and couln't I just save these files to a storage medium (burn data to a DVD or an external drive), and wouldn't these files maintain their HD format? Then, when I get an HD-DVD burner, couldn't these files be re-introduced to iMovie (or Toast Titanium) to burn to a new HD DVD?

You *could* store those iMovie project files

In reply to: Here's a question

as indicated... But after the most recent iMovie upgrade, I would be pretty careful with that... iMovie HD (AKA: iMovie 5, I think) was the first version to handle high definition. iMovie 6 got along well with those files. The most recent version of iMovie (included with iLife 08) is not backward compatible with iMovie 6 - and folks who upgraded yelled loud enough at Apple that Apple is now allowing iMovie 6 to be a free download.

An hour of standard def video takes ~ 13 gig of hard drive space on your computer and an hour of hidef video takes 3x-4x more space.

Then, depending on how you work your iMovie projects, no matter what you do, you can get back to the original clip - not quite "non-destructive" editing as in FinalCut, but the end result is that the iMovie files end up keeping a LOT of information (hence taking up unnecessary hard drive space).

The Share... activity should be to save the file as "Full Quality" Quicktime. These are pretty big files, too... but it should accomplish what you want to do (and get rid of all the unecessary file iMovie was saving for you). Depending on the length of these projects will determine whether a DVD will hold what is needed or if large external hard drives are required.

The other issue is whether the poster's video editing application has these "save as" capabilities... I have no clue.

By the way, I just did one so I checked the file sizes... The original capture camcorder was my Sony HDR-HC1 onto miniDV tape as HDV (1080i)... then imported over FireWire to iMovie...
I started with about three hours of footage (over 100 gig). After all the editing was done, I moved remaining unused clips in the Clips pane to the trash and emptied the trash... The resulting iMovie project file size is now ~53 gig and the edited video in the timeline is 3 minutes: 40 seconds: 21 frames. Just to make it easy, I did a "Share: Full Quality". The resulting file is 2.22 gig... When I am ready, I can re-import this HD (.mov) video file to iMovie or FinalCut and move it out to HD-DVD or BluRay. I chose to export the project back to my camcorder because miniDV tape is cheap - and it is easy to do.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
