Since there are several questions about using the Xacti FH1 with iMovie in the main Xacti thread, I thought I'd start a new thread to discuss a workflow for using this camera in iMovie '09 on Macintosh computers. First, let me say that this works very well if you are patient with the huge files and some sluggishness of the program considering the data load it is having to manage. This is my personal workflow and I will try to explain why I do each of these steps.
1. Set your camera for Full-HR mode which is 1920x1080 60fps. I ALWAYS record in the maximum possible quality as that is the whole point of this camera. Anyone wanting to film at 30 Hz or with interlaced recording should buy another camera due to limitations with this one (chief among them being weak image stabilization and the quirky zoom discussed below).
2. Turn off digital zoom. Digital zooms reduce quality of the recorded image.
3. Be very careful about recording footage at the high end of the optical zoom range. Recording quality is poor at the high end of the optical range for a simple reason: Sanyo has developed this nifty technology called "16x advanced zoom" which is detailed on this page

Sanyo seems to be high on it, but trust me, this is a disaster. Any footage recorded at the high end of the optical zoom range will be subjected to this non-defeatable electronic trick that increases zoom, and image quality will suffer. I demonstrated this clearly in my recent recording of a play where I filmed some material at intermediate zoom and others a the high extreme of the optical zoom, and the latter is quite "fuzzy". It looks kindof like it is out of focus, but that's not really it. It really is just "digitally altered" which looks poor compared to the intermediate zoomed material.
4. Film your footage. Be sure to plan to stop the recording about every 20 minutes and then restart it, because if you don't, and you are recording a continous event like a play, then as soon as the file size gets to about 4GB, the camera will close the file and start writing a new file to card (this is because the format used for the SDHC card is FAT-32, and 4 Gig is the largest possible file that can be written to this disk format). This will introduce a pause into your recorded footage. I'm of the view it is better to introduce the pause yourself at a good point (such as when the lights go down between acts) rather than have the camera do it at an inconvenient time (such as in the midst of a dialog).
5. Use Xacti Library to back up all your raw footage (films and photos) before doing anything else. I cannot overemphasize this step. I was AMAZED by the Xacti Library feature. In a nutshell you can connect a USB 2.0 hard drive directly to the camera and then download all your footage to the hard drive. This works flawlessly, and now your footage is all backed up. You can even play the movies off the hard drive through your camera. But the main point of it is to ensure that you have a full backup of your footage before playing with the card and ultimately reformatting the SDHC card (I use a 16 GB card for 1.5 hours recording time at Full-HR quality).
6. Now you are ready to connect either the camera itself or the card via a card-reader to your Mac. It will launch iPhoto first if you took any still photos and import those normally. Then you manually launch iMovie '09 and it will prompt you to import your footage. This is where I ran into my first hiccup... iMovie did not find all the footage on my card and did not import everything! I kept trying to find a scene in the play I had recorded and could not find it. I then verified that it had in fact not been captured by iMovie, AFTER I had already erased my SDHC card! This is when I was very grateful for my Xacti Library Hard Drive! I simply connected my hard drive, manually told the program to import movie, and navigated to the folder containing all my recordings and it imported them fine.
7. Once you have imported all your footage into an iMovie event, you can then edit your movie fine. Note that iMovie will not transcode these files since it thinks these are in Quicktime format. Note that while these files are MP4 files, the container is wrong and so it will be sluggish and choppy to edit them. I suppose one could use Quicktime to convert them all to Apple Intermediate Codec, but I'm not sure if this would preserve the 60fps frame rate so I haven't tried this. You can edit the files natively (and I'm using the slowest Mac you can get [a 2GHz Mac Mini]) they are just sluggish so you need to be patient.
8. Trim your clips, add music, transitions, whatever as you normally would in iMovie.
9. Thus far, iMovie has retained your source files in all their pristine, untouched 60fps glory...
10. The most important part of the process is getting the final movie out of iMovie without destroying the image quality of this camera or the whole point of buying it, namely the 60fps frame rate. To do this, select Share, Export using Quicktime, and then select Options, Video Settings. On this page, specify the following parameters:
Compression type: H.264
Frame rate: 59.94
Key frames: every 24
Frame reordering: Unchecked
Data rate: Restrict to 24000
Compressor: Faster encode (single pass)
Under Options, Video Size select dimensions HD 1920x1080 16:9, leave preserve aspect ratio and deinterlace source video unchecked.
I leave filter off, and sound settings at their defaults.
11. Now, depending on the length of the movie you plan to render and the speed of your Mac, you may either need to go out for a meal or go on a weekend trip somewhere! When you get back, you will have a Quicktime file (MOV extension) that is 1980x1080p, 60fps. This file will also likely be difficult for your computer to play, but now you can easily convert it to other formats using various video conversion programs. One of the nicest playback options is to use the PS3; this beast can easily handle the data-rate, but it does require conversion to the correct container. I use Red Kawa's PS3 Video 9 program on the PC to generate perfect 60fps files that the PS3 can play back flawlessly. My monitor is capable of displaying a 1080p/60 source file natively so this looks incredible. My wife says my home movie made according to this work flow looked better than prime time high definition programming... a rather nice endorsement.
Have fun!
