I have a video that needs to be replicated approximately 100 times with the only change being a logo, some text and phone number. What is the quickest way to achieve this? I would need to make the edits using XML, then rendering, then even uploading directly to Youtube would be nice. Any help would be greatly appreciated.
You need to get into scripting. Search AEScripts and other such resources. E.g. the Comp from Spreadsheet script might help. You can't upload directly to YT from any Adobe app. You'll have to use otehr tools to do that or get into their API and write your own little app/ script.
