Poster Frame not working?!
I am editing a short clip for a client for social media. I have spent HOURS trying to get the video to show the introductory screen as it's "resting place" before you hit the play button. I have tried all of the "poster frame" setting options in Premier, Shift-P, going to thumbnails view and right clicking to select "Set Poster Frame", stopping the slider and selecting the camera, which displays "Poster Frame". Alas, when you view the video in either windows explorer or drop box, the frame selected is neither what is displayed prior to hitting "play" or what is displayed as the thumbnail. I have tried encoding in Premier Pro and exporting to Media Encoder. HELP! I look like an idiot to my client.
Is Poster Frame not what is used to set both the starting image and the thumbnail. Educate me, PLEASE!
Here is a screen shot of what the video looks like when you view it:
