Edit in iMovie

Question

I want to re-edit a movie but after going iMovie>garage band>iTunes, it's in .MOV container.
iMovie will not recognize. What settings I need, to convert again for iMovie in MPEGSTreamclip by not doing a re-compress ?
the format is :
Data Size: 669.42 MB
Bit Rate: 3.97 Mbps
Video Tracks:
H.264, 960 × 540, 25 fps, 3.78 Mbps
Audio Tracks:
MPEG-4 Audio stereo, 44.1 kHz, 195 kbps

Answer 1

And how can I delete the track ?
There are two basic methods of deleting extraneous tracks of data:
1) The first is rather "hit or miss" and basically relies on track type compatibility with the various file containers. An MOV file container can contain up to 99 tracks of data that may consist of one or more tracks of audio, video, image, text, timecode, sprite, "Tween", etc. content. Take an iPhoto slideshow exported as an MPEG4/AAC file for instance. It will not import to iMovie '08 because it contains a "Tween" track. However, since the MPEG-4 video and the AAC audio is compatible with an MP4 file container but the "Tween" track is not, placing the audio/data in an MPr container using the MPEG Streamclip (free) "Save As..." option will automatically "strip" the target file of the "Tween" track because it is incompatible with the file container and cannot be copied to the new file. This, in effect, is one way to delete the "Tween" track without re-compressing the data itself. Unfortunately, this method only works if the audio and video content is compatible with the MP4 file container and your extraneous track is not compatible with the MP4 file container.
2) The preferred method would be to use the QT Pro Player application. This will work with any QT compatible file. The basic strategy here is to simply open the file in the QT Pro Player, open the "Properties" window, select the track you wiah to delete, and then press the "Delete" button in upper, left-hand corner of the "Properties" window. Further, This application will also allow you analyze which tracks are and are not compatible with iMovie '08. In this case the strategy is simply to extract the video track, save the new player created, and then try importing it to iMovie '08. If it imports, the video content is compatible with iMovie '08 and if it won't import, then it isn't. Thereafter, you can successively extract other data tracks and add them to your extracted video file, save the result, and again try to import the newly created/saved file. Once aga, if it imports the newly added track is iMovie '08 compatible. It it isn't, then you can go back and eliminate the incompatible track from your "test file" and continue adding extracted tracks until all of the original movie tracks have been determined to be compatible/incompatible and you are left with a test file that is completely compatible with iMovie '08 (with the possible exception of Apple Animation and/or Apple Video compressed video tracks which are know to be import and edit compatible but cannot be exported correctly from iMovie '08).
I do not want to delete any track, only want to insert a small movie in it. What should I do ? Export to MPG4 in mpegtraemclip ? What settings I will need without re-compress ? the source is H.264, 960 x 540, Millions AAC, Stereo (L R), 44,100 kHz
It depends on what you mean by insert here. If you are referring to the inserting of a "window-in-window" effect, then neither MPEG Streamclip not iMovie '08 will work since neither has movie layer/compositing capabilities. If you are referring to the insertion of a clip into a cut/splitting of your file, then this can be done in QT Pro or MPEG Streamclip, but not in GarageBand which only allows the presence of a single video/podcast track at a time or iMovie '08 without either deleting the problem track or re-compressing the file which you say you are not willing to do. This process does not usually require re-compression as files of differing content can be merged and saved in the MOV file container and in this case the strategy is focused on the correct placement (frame level inserting) and not the compression formats involved. Unfortunately, the work flow depends, to some extent, on which application you want to use, so I will not go into details at this time.
Of course, "noticeable" is a relative term and that is why I tried to be more specific and mentioned the "average viewer." I'm sure a videophile could tell the difference.
Am sure most of us here agree with you on this point.
