      Several basic questions:  I notice not all my mp4 files import.  Some do some don't.  I was told by adobe support to encode to avi.  except for the large files, is the output (dvd) going to deminish in quality because of this encoding.  Should I encode it to something else?  It did work on one file that failed as an mp 4.  seems like a lot of time would be spent doing the whole 1 hour segment.  2.  I've read that the avchd is farily hard to work with.  I need to buy a new camera.  current new computer config>  i7 960 processor, 9 megs ram.  good video card two t harddrives (one for programs, one for assets).  With this config, is a avchd format camera a good choice, or do I need to go a different route. sorry if these questions are basic, tried to locate the answers, but was unable.

          The key is what CODEC is in that file?


          MP4 is a highly compressed format that is, generally, made for viewing and not editing... more info at http://www.pacifier.com/~jtsmith/ADOBE.HTM#edcf

          Yes, AVCHD is not easy to edit, and requires a powerful, properly setup computer (see link above)

            MP4 is but a "wrapper," as John mentions. It is like .AVI, .MOV, .WMV, etc., and can contain all sorts of CODEC's (the "building blocks" of AV files). This ARTICLE will give you some more background on those "wrappers," and how to peek inside them. For a primer on CODEC's, this ARTICLE will give you some useful links.


            For your MP4 files, it is very likely that they are not created equal, and differ inside. It might be the CODEC, or implementation of the CODEC.


            In a perfect world, one will work with footage from the same camera. With footage from several sources, one has a challenge ahead, and conversion might be the only way to solve the issues.


            Good luck,
