I'm using Premiere to edit some drone videos. After I export the video and it's converted to an MP4 when I play the video it continues far longer than the actual video image and shows a blank screen for another 3-4 minutes. How do I end the file size where the video images stop. Very frustrating. Thanks for any help.
You may have a stray frame or piece of the clip stuck out to the right on your timeline. Pressing the "\" will fit the entire project into view. It should display across about 3/4 of your screen. If it looks smaller, you have a stray clip. It may be on a different track.
If you don't find the stay clip, use the work area bars to restrict the output.
You can try the 'next edit point' button to bump forward from clip to clip. It should find any stray clips off to the right.
