    H.264

      I am thinking of buying a Samsung SC-HMX20 camcorder. It says it compresses video using H.264(MPEG-4.AVC) main profile format.

      Simply question does premiere elements 7 support this coding and
      has anyone got any experience with this camera.

      Thanks

          Premiere Elements 7 will edit AVCHD hi-def video, Chris. And, from all reports, it does a pretty good job at it too.

          It does require a pretty powerful system, though, to handle these hi-definition, highly-compressed files.

          Here's a list of our system recommendations. If I were you, I'd look into the highest recommendations in the article.

            Thanks steve

            From what I gather from reading some comments on the web the Samsung doesn't use the AVCHD extended form which Canon and Panasonic use but H.264(MPEG-4.AVC) main profile format. Can I assume this can be read and processed by premiere 7. I understand about the processing requirements.

              I don't know enough to comment on that.

              Anybody else have experience with it?

                  "AVCHD is a high-definition recording format designed by Sony and Panasonic that uses H.264 (conforming to H.264 while adding additional application-specific features and constraints)."

                  I'm not sure the two are always interchangeable.

                    I am using PRE7 to edit AVCHD video in .MTS (from my Canon HF100). I have two issues. The first is that for some reason PRE7 will not "smart render" (i.e. if you want to export it, it re-renders the whole clip even if you've done absolutely nothing to it). IMHO, if you've done nothing to the clip or if all you want to do is snip a little off the beginning and/or the end of the clip, PSE7 should allow you to drop it in the timeline, do your snips, and then "smart render" the result without having to re-render the whole thing from scratch. Other software (from the Pixella ImageMixer software that was included with my camcorder, to Nero to Vegas) support this pretty basic function, and I frankly am stumped why PSE7 doesn't -- particularly since Adobe was so late getting into the AVCHD "game".

                    Second, and related to it, is that I'm getting a "Multiplexing has failed" error when I try to export in "h.264 1920x1080i 30", but there's more on that here: http://www.adobeforums.com/webx/.59b6c530/1

                        I don't think Adobe has ever used any kind of smart rendering with any kind of video in any of their software. I agree that it's a pity. However, I can think of a number of PE7 competitor packages which don't smart render - either by design or because they're supposed to and don't. Nero indeed is very good at that, but pretty limited in all other aspects of its operation.
