I am having an issue exporting from AE to MP4's for Safari 5.1.5 running under OS X Lion. The videos no longer play. As far as I can determine, this is only an issue under Lion. Of course, this is the browser the client uses. I have tried all variations of exporting from AE, direct from QT 7 etc to no avail. It seems like there must be a flag to set somewhere that will work. Any pointers greatly appreciated as I have been pulling my hair out and other sites on the web haven't been any help.
Have you tried using AME instead of AE to export/render your H264? FWIW, choose the H264 format instead of Quicktime>MP4. You can import/add an AEP into AME whereby upon import, you will be allowed to choose a composition to render, all from AME, without having to open AE. The advantage AME has over AE is its -pass VBR encoding.
