I know that if I click the Use previews box it speeds up my render substantially, but I was wondering if it lowers my output quality on the final export?
Yea I just went through a four hour export experiment trying different combinations of H.264 with previews, without previews, 1080p 720p email@example.com, High@4.2, adjusted bit rates, etc. My conclusion, don't use previews for final export, max bitrate, high@ 4.2 (since many don't support 5.1-still don't really understand this area though), and use 720p since many systems cannot playback 1080 without choppy playback. I think this is my best option for my 2 minute video...I hope.
Also, I am exporting to Vimeo and I noticed they have a 720 and 1080 option. The question I have now is, would it be best to export at 1080p from premiere, and then show at 720p on Vimeo? or would I just go 720p all the way? Both options of course with the same settings mentioned above.
