media encoder,not encorder
Here the issue lies with Media Encoder, as your animation shows fine before exporting, but its lost after exporting.
Therefore I am moving this thread to Adobe Media Encoder (AME) forum, so that the experts out there can look up into the issue.
Please provide a screen grab of the export setting is AME so we know what you are doing.
