I am currently trying to export a video from AE as an MP4 sized 335 x305. My first attempt produced black bars. I have looked around forums and following the suggestions exported as an avi and attempted conversion in Adobe Media Encoder with no luck as it keeps wanting to resize the video.
I need to maintain the video size as its going in a specific spot on a webpage and I need an MP4 format so that it can run on Ipod and other tablets.
My second question is transparency. Is there a way to maintain background transparency in the MP4 export.
