I just made a 25-minute video with 100 slides in it and HDV footage running under it the whole way, mostly because I wanted the audio from it. I used some of the video in it to. My project settings are good. I tried twice to save it in H.264 on the Youtube HD setting (and setting the width to 700 pixels with locked aspect ratio). Now I'm processing it in the default MP4 setting. Also, I export with Adobe Media Encoder.
Is there anything here that indicates why the YouTube HD setting would render a video that comes out shaky? This is new for me. Twice it comes out with footage and slides (with no footage showing) shaking.
UPDATE: The default H.264 setting in Adobe Media Encoder (728 pixels wide, I believe) came out well. I wonder if that YouTube HD setting has a problem. I wanted to use it and to understand the limitations.
