Real video photographers would strive for higher and higher resolution and higher frame rate. If properly handled, that might make the end result more professional-looking. However, as was noted, you have to have the back end stuff to squeeze all of that performance out of the video file.
The good news about a more modest resolution and frame rate is that it makes the video file smaller and more compact, so it makes it more portable for transfer around the Internet.
One thing about the video files is that there are different degrees of video compression. Some are better for slow action, and some are better for fast action. You just have to decide what you want to end up with. Also, some video file formats are easily editable, and some are not. I have some utilities to convert files out of the native format of the camera and into something that is more friendly for the editor. Of course, some people never edit a video file. There's no fun in that.
Additionally, you want to decide how you feel about audio. With some cameras, you can record audio right along with the video, all right in the same file. With some cameras, the microphone isn't worth a damn, so you end up with a lot of muddy and scratchy audio. You can add on serious microphones if you want. You can also add on an audio field recorder and record your own audio independently from the video. Or, you can simply graft on a music track when you have the bare video in the editor.
Too many choices.
