Coppatop65 - I'm not sure why folk think that they have to "edit *.mov" files.....
My Canon SX10 and Fuji HS10 both save video in the MOV container, and I certainly don't edit either the SX10's 640 x 480 MOV, or the HS10's - either level - of HD MOV.
The cameras save H264 video in Apple's Proprietary MOV container.
H264 is a subset of MPEG4 - controlled by the Motion Picture Experts Group (can Google that) - and can either use the *.avi or *.mp4 extensions. H264 is just a later and more efficient/compressible version of MPEG4 - also called MPEG4 AVC - Advanced Video Codec.
You can strip the MOV container from the H264 - the result is then "Vidname.avi". That gives you a smaller filesize to convert or edit. However, as H264 is quite recent, I don't know if all Editors in Windows can handle it.
However, it converts readily to Compliant MPEG4, which most Editors handle. (Or Xvid4, better than MPEG4, and a converter / editor standard in Linux.)
If you just want to remove 40-seconds from the head of a file still in the MOV container, and use the remainder in the MOV container, you can use Avidemux, free for Windows, Mac, and Linux.
Download and install Avidemux. Works very well in XP - can't say for Vista or Win-7, as I haven't used those.
Open Avidemux, and drag-drop your MOV item into the window. It will ask you, "H264 detected" and options. Click the "No" button, and your file will open in the window.
On the bottom slider bar - advance your video to the 40-second point, and click-in the A-marker. If you are retaining all of the rest of the video, the B-marker will go at the end of the video.
Go to - File > Save > Save Video - click, name your extract, and select a Destination. Avidemux will cut the video at the closest reference-frame to your 40-second A-marker, and Save the Re-named remainder between the A and B marker points, into the Destination directory.
From that directory, just run the video to be quite sure the cut was accurate. Rarely, you might need redo it, moving the A-marker back a few thousandths of a second to get the cut at the reference-frame, but usually not.
Avidemux doesn't alter the original file while doing this - it copies the A > B section as an extract and exports it - that's why the new filename is needed.
You can strip the MOV container from camera H264/MOV clips with Avidemux. Drop the Video into Avidemux, under Video on the left, select "MPEG4 AVC (x264)" (x264 is the OpenSource converter) - Audio leave, as Copy, and export Format, at the bottom, is AVI.
If not sure that your Editor uses H264 - just convert to compliant MPEG4 instead.
You can use Filters, Sharpen, Brighten, etc, and resizing, in Avidemux. Or just convert your MOV to MPEG2, resized to a DVD compliant *.mpeg(2) file. (Format exension is "MPEG PS (A+V)".
Use the *.mpeg(2) in DVD-Styler (free for Windows, Mac, Linux) - to create a DVD ISO, compliant DVD-fileset, or with Intro and Menus made in 'Styler, burn to TV-playable DVD.
If not clear - post back....
