There are many flavors of MP4s, unfortunately, and not all behave the same way and not all, by any means, are easily digested by this program.
The program does handle AVCHD video, which is in the MP4 format. But it can have real problems with video from sources like inexpensive pocket camcorders, like the Flip, which also produce MP4s but which use a proprietary codec that almost no PC video editing app can handle.
What model of camcorder are you getting this video from? The fact that you say you're pulling it off a "card" seems to indicate that it may be something other than a standard AVCHD file.
If so, you'll just need to convert it to a more editable format. How you do that and what you convert it to depends on if the video is hi-def and if you need it to be in hi-def after you convert it.
hmm...that sucks. well, i am getting it from a sony digital camera (DSC-W290) that claims it produces 1080p videos. they are pretty dang good videos. its a great camera. yeah, i need them at any cost. if i can keep them high def that'd be fantastic. if not then no big deal but its the easiest way to make videos for me. i use this camera all the time. i guess the only thing i havent tried is plugging my camera into the computer and pulling it directly from that but i have tried various ways of pulling it off my media card that i pulled from my camera. i plug the SD card into the computer and that hasnt worked at all. do you think pulling it straight from my camera would work? if not what other options do i have? thanks so much for your help!!
Sony usually ships with a browser. I'd look into using that to transfer the files to the computer. Then, you should be able to Get Media>Folders Files. Is that not working for you?
Have you seen the recent thread of APK-1 and his "red" video? Apparently his Sanyo camera shoots SD and HD, and it was the HD video with the red video issue. He is now OK with Premiere Elements and the HD video and MPEG Streamclip conversion of it.
