I understand that it is critical when using Adobe Premiere Elements 10 that the video settings of your project match the settings of your camera. I want to upload video from my Nikon D300s DSLR which has the video setting options of 480P (640 x 480), 576P (720 x 576), 720P (1,280 x 720), and 1080i (1,920 x 1,080). I will primarly be making videos either to upload to You Tube, or save on a dvd. Can anyone tell me which would be th right settings for my camera and Premiere?
It depends on which resolution you're shooting your videos in.
It looks like that cam shoots in 1280x720 at 24p. There should be a DSLR project setting for that.
But if the camera shoots in all of the video modes you've listed, you can shoot it in any -- just make sure to select the DSLR project settings that match the video.
Personally, I'd shoot in 640x480 to start out with. It will be the easiest to work with. Then you can work your way up to 1920x1080 if you feel the need.
