I am having an issue opening my mp4 files. Can you help me?

[Debbie M.1]

I shared a mp4 video from mac to dropbox but the file cannot be opened by a MS OS device. Realplayer is the default so it should work for any OS device. Is there something special I need to do when I upload the file to dropbox or before I share the link from dropbox? Thank you

Hi there,

Sorry for the late response - are you still having issues?

Thanks

[Debbie M.1]

Yes I am still having issues. I haven't been able to successfully open the iMovie using realplayer. Do you have any ideas? Thank you

Having thesame issue: cannot play mp4 files on iPad and iPhone, they're saying files are 0 MB but MacBook says files are the real MB's???

Debbie - thats an issue you need to speak to iMovie (Apple) and Real about. It isnt anything to do with Dropbox. 

That means they've not yet fully uploaded Riet. Apple creates 0byte files when you move data around and then fills them up. Dropbox often uploads the 0byte files before they finish uploading. Those 0byte files will change to full ones once the computer uploads them.

Thanks Mark, indeed, I was too fast. Uploading/synchronising took more time than I thought.
