If the file size is the issue, you should see an error message when you upload to say whether the file is too big or small.
The file size parameters are as follows:
Min - 10mb
Max - 600mb
Please note that file type can also be an issue. With you recording the content on your phone I would expect the video would saved as mp4. These are the file types we accept, so might just be worth checking this too.
Video File Formats: 3g2, 3gp, avi, flv, m2v, m4v, mov, mp4, mpg, ogg, ogv, rm, webm, wmv
Hope this helps, let me know if you are still experiencing any issues.
Take care,
