(I removed the nice vendor as I am going to talk about a different
product and did not want to offend...)
The ability to edit the video *can* be based based upon the
COmpression/DECompression method used. Some CODECs are only good for
output based upon the way they compression video... they don't lend
themselves to non-linear (NLE) editing. For a long time MPEG was that
way. This could be the reason. I get similar types of output files
from one of my cameras...
And speaking of files... It seems that the Canon SureShot camera
provides '.avi' files, true? In that file the video format is motion
JPEG or MJPG and the audio is PCM format (pulse code modulation).
This format is typically chosen as it offers the best quality for the
lowest processor usage (and hence cost of processor and camera battery
consumption). My Fuji does this too... annoying.
So the first thing I do is convert to MPEG-4. Even though I am a big
QuickTime fan, MPEG is the only true video standard which means that
it will be supported for probably longer than VHS. It is also
supremely scaler (from dinky Motorola Q to BluRay HD beyond 1080p).
But if you have any serious editing to do, I would recommend up
converting to DV format. When you import into iMove, FinalCut Pro /
Suite or import from a professional video camera this is what you get
(part of the base definition of FireWire's transport). DV can usually
be imported or used anywhere any serious video editing tool used.
iSquint is good. I also use Stomp from Shiny White Box http://www.shinywhitebox.com/
(iShowYou is also a nice product)
But back to the simple and easy... most of the time I simply use the
built in output routines in QuickTime Pro that Apple gen's up. Their
quality vs bitrate on iPods, iPhones, etc is excellent. As in all
Apple output, they will error on better quality over lower bandwidth
or bitrate. An added benefit is that QuickTime Pro is massively
multithreaded. I will commonly ratchet up 5 or 10 video compressions
(transcodes) all at the same time and let it go. Lastly, QuickTime
Pro can be commanded via Automator for a workflow... you make a drag
and drop application that spits out multiple versions of a video in
MPEG-4, one for iPhone, one for first gen video iPod, 2g video iPod,
streaming, etc. You can even make a 'folder action' on a Mac to pick
up any new file and automatically generate multiple copies into a
project folder in the same directory... a video compression server...
Anyway, long story short, I would concur that moving it from the
'.avi' to a broadcast quality format (MPEG-4, DV, etc.) is the best
bet. I seem to recall that iTunes can do this too (via the QuickTime
engine of course)
V/R,

Update. I think the issue was the camera I used. When I use video
from other sources or the Isight camera, the QuickTime works. But
if I use my SureShot pictures, the option of editing isn't available.
There are very few things that quicktime pro will not edit (but will
play).
If the option of conversion is available to you then I recommend
iSquint. It is an app designed to convert videos to a format that is
compatible with ipods, Apple TVs, iPhones, Quicktime, etc... and is
based on the open source tool ffmpeg. It was originally the freeware
version of VisualHub (which has apparently been forcibly shut down).
You can download this app from:
http://dl.macupdate.com/final/multimedia/19769/iSquint1.5.2.dmg
Information about the application and their recent close down can be
found at:
http://www.macupdate.com/info.php/id/19769/isquint
Information about ffmpeg (the open source engine involved) can be
found at:
http://www.ffmpeg.org/
You might wish to hurry up and download though because the link
above is one of the few remaining mirrors that appear to be open and
will likely (in my impartial and humble opinion) be closed as part
of the "loose ends" cleanup.
