Amid much expectation, Core Contents Media has informed fans that T-ara's new music video for their upcoming comeback "Day by Day" will be delayed for 13 hours.

Originally scheduled to be released at midnight, July 3rd, the new release hour will be at 1:00 PM on the same day. "Due to the lack of completion for the computer-graphics work, the release has been delayed by 13 hours," CCM said.�Since the music video takes place in the future, a large amount of work is needed for accurate computer graphics - around 15 days' worth.

Although work was done around-the-clock to have it finished within 10 days, there wasn't enough time to properly finish the CG work, leading to the slight delay.

"Because T-ara's music videos are always blockbuster-quality, due to the large amount of CG and audio work our videos are always delayed. We are very sorry," CCM apologized.

Part 1 of T-ara's "Day by Day" music video will be released at 1:00 PM on July 3rd, followed by their first stage performance on July 7th's episode of MBC's 'Music Core'.
