Road To V entrants will be able to be seen and heard during this year's competition, with bands able to upload videos as well as music for fans to enjoy.
The best videos each week will also be shown on Virgin Media's Video On Demand, giving artists the chance to be seen by thousands more potential fans.
The contest, which is now into its sixth year, will search for the very best emerging talent to fill two slots at this August's V Festival.
The competition is open until Sunday 12 April.
Ten lucky finalists will also get mentored, and play alongside, two big acts at The Great Escape festival as part of the live stage of the competition.
The public will choose the first two finalists before the two artist mentors handpick four acts each for the final.
After a live show, which will be filmed and broadcast on Virgin 1, the public will ultimately select the two acts they want to open this year's V Festivals.
Previous winners of the competition include Young Knives, Johnny Foreigner and The Rebs.
For videos, the organisers can accept: AVI, ASF, MOV, WMV and MPEG files, in either 16:9 or 4:9 ratio.
