Perhaps this post is long overdue. In reality, you can find a lot of this information elsewhere in this blog, but I think that having it all contained in one, easy-to-link post will help smooth the transition for those taking their first dive into iMovie '08.

So here it is. If you used iMovie HD, here are the things you should know about iMovie '08 before you get started.

1. Don't expect iMovie '08 to behave like previous versions of iMovie.
This is the most important thing I will say to you. It bears repeating:

Don't expect iMovie '08 to behave like previous versions of iMovie.

If you switched from Windows to the Mac (or from OS 9 to OS X, for that matter) you had to relearn a few things. Trying to get the OS X to act like Windows only resulted in frustration. Buttons were in different places. Functions did different things. The same concept applies here. iMovie '08 may share a name with iMovie HD, but they are two completely different pieces of software. Use iMovie '08 the way it was meant to be used.

If you were a heavy iMovie HD user, the editing process may confuse you at first. For example, you won't be able to use a traditional timeline view. Be patient. You will learn it quickly and probably, as in my case, learn to love it.

2. iMovie '08 uses nondestructive reference editing.
What in the world does that mean? Well, in old versions of iMovie, if you trimmed a clip, the actual video file in the Finder was trimmed. Once you were beyond the limited power of the Undo command, these changes were irreversible. If you regretted an edit, you'd have to reimport video from your camera, assuming you still had it.

iMovie '08 doesn't work this way. A movie project in this version acts something like a big list of instructions. All the source video is stored safely in your Event library and iMovie '08 just makes a list of what pieces should appear where. It doesn't actually move or edit your source footage. (iMovie will edit or move your source footage if you are rejecting it for deletion or reorganizing your events.) Everything you see when you preview a project is just a representation of "the list" that iMovie is creating and showing you on the fly. As far as I can tell, this is one of the reasons older Macs don't run iMovie '08, because creating a preview on the fly is demanding on the computer.

The benefits of this ability:
* Your source footage is always safe and sound.
* Using footage in two different projects does not require two space-hogging copies of the same clips.
* iMovie doesn't render anything during the edit process. Transitions, titles, and color effects are instantaneously available.

Some warnings:
* Don't mess around with Event footage in the Finder, unless you know what you are doing. If you delete event footage, all projects using that footage will be broken.
* You don't save projects. This means that if you want different versions of an individual project, you need to make copies of the project in the Project list.

3. iMovie '08 is missing some features found in iMovie HD, but not all the features others have said are missing.
Missing features are the biggest complaint that most people have about iMovie '08. Unfortunately, many people (myself included) had a knee-jerk reaction to iMovie and made some unfounded accusations. In fact, you might see some people refer to this version of iMovie as "iMovie Lite". (An ironic name considering some of the incredibly advanced stuff that iMovie '08 does that no previous version of iMovie can do.) I'd like to dispel some misconceptions before you start using iMovie '08.

Here is a list of key missing features.

* Video effects (including fast/slow/reverse) other than color adjustments
* Audio effects
* Themes
* Export to camera
* Chapter creation for iDVD
* "Rubber band" audio editing
* Some styles for transitions and titles

Here is a list of features still in iMovie.

* Frame-precise editing
* Precise audio level editing and fading
* Multiple audio tracks
* Extracting audio from a clip
* Adding black space to a project
* Sending movies to iDVD, iTunes, iWeb, or GarageBand
* Capturing a still image from a video clip
* Selecting multiple clips

Of course, there is an impressive list of things you can do in iMovie '08 that you cannot do in iMovie HD, but people inclined to complain don't spend a lot of time on these. Here are some of the really nice things you can do in iMovie '08.

* Crop or rotate video clips
* Footage organization tools, like favorites and keywords
* More than two audio tracks
* Advanced, flexible typography in titles
* Using images with transparency
* Adaptable editing interface
* Full screen scrubbing

3a. You can edit audio with basically the same precision, it's just done differently.
The very common complaint leveled against iMovie '08 is that you can't edit audio as well. This isn't a fair accusation. The rubber-band tool is gone, but you can still have audio dip at just the right point to just the right level. Just a few observations about this:

First, you can't edit audio within a clip, which means audio changes always apply to an entire clip. But, you can easily split clips. This is important to getting particular parts to dip or swell in the right places. Splitting clips doesn't effect the end product.

Secondly, as of the 7.1 update, you can get audio to fade in and out with custom settings you determine. This means a fade can last half a second or up to two seconds.

Just remember that, in general, editing audio revolves around the video clips. You don't need to dip an audio track itself, instead you just tell the video clip to dip all the other audio around it.

4. Keyboard shortcuts in iMovie '08 are awesome.
iMovie is still crazy-easy to use with just your mouse, but if you want more power you can get it. In fact, be prepared to enter an editing world where you feel like one of those pros who has a keyboard with different colored keys just for video editing. The keyboard shortcuts in iMovie are multitudinous.

More importantly, Apple recognized that you don't need the normal keys on your keyboard for actual typing. This means a lot of the keyboard shortcuts don't require the annoyance of modifier keys, like Shift or Option. (There are still plenty of those kind of keyboard shortcuts, but mostly because Apple is getting full use out of the keyboard.)

Why use keyboard shortcuts? They are fast and pretty easy to learn. You will feel like a pro when you edit, and you won't have to spend a lot of time learning before you start using the keyboard like crazy.

To view a list of keyboard shortcuts, go to the iMovie Help menu, open the help application, and search for "Keyboard Shortcuts."

5. Thumbnails can take a long time to make, so plan ahead
When you first add some footage to iMovie and discover that it may take a long, long time to make thumbnails for your footage, you might wonder if you did something wrong. You didn't. Thumbnails are just an integral part to the skimming ability of iMovie. If you don't have the time to create thumbnails for a whole set of footage, do what you can to import just the video clips you will need for your project.

6. iMovie '08 is still a work in progress.
If you decide to use iMovie '08, consider yourself an early adopter. And what that means, Early Adopter, is that you might encounter bugs or other problems. These are a tradeoff to all of the rather amazing features iMovie '08 provides to you.

It feels to me something like using OS 10.0. When OS X came out, I insisted on using it because it was the future. With each new version, I saw the different bugs melt away into what is now the best operating system ever made.

As an early adopter, you will also have a chance to contribute to the future versions of iMovie. Apple reads all of the feedback people submit through the established channels. If you submit thoughtful, insightful feedback, don't be surprised if Apple makes an improvement as a result.

I hope these comments are useful. Having the right expectations from the start really does make a huge difference in the way you will use iMovie '08.
