In this video, I cover the settings used for exporting a project video out of Adobe Premiere Pro with high quality high definition settings. This should be similar on Adobe Premiere Pro CS3, Adobe Premiere Pro CS4, Adobe Premiere Pro CS5 (what I’m using).
When you export a video from Premiere, make sure it is fully rendered and the entire project is selected. Export in 1080p high definition.
These might be the best settings for exporting videos for YouTube in HD, but you could know better settings-please share with us!
