Thank you both for the prompt responses.
I like the idea of bringing the footage down to letterbox format, but I’m a little concerned because I didn’t set out with that idea in mind and have already put many hours into editing the footage.
Currently, my Premiere Pro sequence is 1440 x 1080 (1.333)
Within it, I have my SD 720 x 480 (0.9) footage and my HD 1440 x 1080.
Can I convert my existing work into a format suitable for the letterbox method you have described without losing what I’ve already done?
The final video will be played back on everything from older televisions to newer HD flat panel models. I am worried that attempting to “letterbox” the footage in my current wide-screen sequence within Premiere Pro might compromise the durability of the video to be viewed on different types of TVs.
Thanks again!
