Video [WP7.8 rooted] How to upload a big video file?

Hi. How can I upload a big video file (~300MB) from my Windows Phone 7 to any online service without resizing the 720p video? Skydrive, Dropbox, Youtube, anything is ok. I have a rooted Nokia Lumia 710 running Rataplan ROM

Move to Cloud is otherwise a really nice app to upload anything to SkyDrive, but there is this nasty filesize limit of about 50-100MB.

Built-in Internet Explorer browser can't upload any files anywehere.

Opera seems to, in principle, allow uploading, but I haven't succeed.

Any advise?
