Using GarageBand (or a newer version of Compressor i believe) they can also be embedded with chapter markers for use with the QT Player, Front Row, iTunes, iPod, iPhone, TV, and QT web player plug-in (web sites). Like the MP4 file container, M4V files can be associated with external image files (i.e., "artwork") for use as "poster frames" in applications like iTunes and iWeb. Either of these two export modes can be accessed using the iMovie '08 "Export Using QuickTime." option under the "Share" menu. Use the "Movie to MPEG-4" option to select the "MP4" file type (i.e., container) and either MPEG-4 or H.264 video encoder. If you are referring to an initial export from iMovie '08 here, use the "Movie to Quicktime Movie " option to place whatever video compression option you use into an MOV file container. How exactly do I determine if I will get a mp4/mov container with H.264/AAC or MPEG4/AAC. If by this you mean 8- or 10-bit uncompressed 4:2:2, the that is also an option from iMovie '08 if you have the proper codecs installed. As to "raw" video, do not know what you want. For that matter, you can use the QT Pro's "Save As." option to place the same content an MOV file container. Since the MP4 file container can hold either MPEG4/AAC or H.264/AAC files you can either export using the "Movie to MPEG-4" export option which will place either combination in an MP4 file container or use MPEG Streamclip's "Save As." option to remove the H.264/AAC content from the M4V file container and place it in an MP4 (or MOV) file container. If you are sending files specifically to Windows users, then maybe DivX or WMV would better meet your needs.Īlso it is unclear whether it is the H.264/AAC compression formats that you object to or just the file container which typically opens in iTunes rather than the QT Player but which you can reassign for opening in QT if you want. If you distribute files on the internet then maybe you want something like MPEG-1 which is fairly universal for all platforms if kept standardized. For instance, do you watch movies in Front Row? If so, then maybe you would prefer MPEG-2/AC3 files. Basically when you just tells us what you don't want, you imply that everything else may be acceptable for you. MPEG4/AAC files require about 2.0-2.5 times as much video data rate to produce the same level of quality as H.264 but encodes much faster. H.264/AAC (in either the M4V, MP4, or MOV file container) produce the smallest files with the best quality for a given video data rate which is why iMovie '08 is optimized for its use and why it is used for the compression of HD content. Motion-JPEG or Photo-JPEG compressed files are usually about half as large as AIC/AIFF files, still produce reasonably good quality and remain iMovie '08 compatible. Many users also like Apple Animation but exporting to this codec would not be compatible with iMovie '08 if you wanted to bring it back in for any reason at a later time. ![]() DV or AIC is commonly used if you need to do further editing or are trying to maintain maximum quality but both of these compression formats produce fairly large files. Use the "Export using QuickTime" to export to other compression formats. It might be easier to suggest a work flow if you would state your goal. In all of the export the extension is m4v which isn't very good for me because I am doing projects for my school and no one around me has iTunes (nor do I like watching my videos through it), how can I export the film as raw?
