I did try exporting in Full Quality (DV) but the result is fuzzy and the image is low quality.
I record the screen on a Windows computer and the resulting output file is an AVI file with a Microsfot Video 1 Codec at 1016x760 with a data size of 41MB.
This opens and plays gorgeous in Quicktime. However, when i import this AVI file into iMovie and export it out again the result is a loss in quality of video.
I need to import this into iMovie to be part of an instructional video. Perhaps double compressing the video like this is the cause of such fuzzy quality. Can anyone lend their expertise in the matter? Maybe someone who has done screen capture before with iMovie. I also welcome any other comments or suggestions!
That is scaled to PAL 720x576...
So: if you original gorgeous clips has any 1 pixel lines, they are scaled to 0 pixels or to some fuzzy intermediate...
Try to adjust the screen capture to 768x576 or 640x480 etc -- then the scaling to 720x576 should be better quality.
Also remember that the DV codec may produce some compression artifacts to some colors.
iMovie is - as allready stated - not choice #1 for editing 'any' codec, nor preparing screengrabs for delivery ..
as an example, honorable forum member +Jon Walker+ uses ScreenFlow (I guess), on his 10.5. capable IntelMac.. in result:
superb screengrabbings. e.g. http://web.mac.com/jrwalker4/MotionEffects/QT_Pro1.html
.. but this is on your set-up no help..
Five years ago I made some beautiful crisp screenshots (stills) to use in iMovie for a talk I was giving.
Of course the results were unsharp and shimmery ......... totally unsuitable.
Matti Haveri has told you the reason. You are converting a high quality computer display picture into a comparatively low quality TV image with only a quarter of the total pixels.
It is not iMovie's fault. Any video editing programme will give the same disappointing results.
There is nothing you can do about it if you want to capture the ENTIRE SCREEN.
However, if you are content to capture an area about half the computer screen width (as Matti Haveri suggested) you will get a very satisfactory result.
I used my Windows Screen Capture software (Cam Studio) and just captured the open window for recording. This does not capture the whole screen but captures the window you click on. When i finished recording it made an .AVI file which i open and save in QuickTime as a .Mov file. Now i add a soundtrack and some other videos into that QuickTime movie for some cool picture in picture effects and added some cool title effects throughout the movie. Everything plays crisp and clear.
I think the problem may have been what was mentioned earlier in that iMovie took the resolution of the .AVI file and somehow compressed it at import and made it "fuzzy". I did not try changing the resolution of the AVI file from the software.
