Drag screen to fast track videos

The Goal:
To enable Viki users to fast track to their favourite scenes. According to our hardcore users, a lot of them said that they would always go back to certain episodes to re-watch their favourite scenes. A useful feature is to enable them to fast-track to a particular scene without any hassle, right on their finger tips.

How?
A simple idea is to press and drag left or drag right with one finger. We got this interaction idea from some podcast and other Chinese video apps.

Engineering Challenge:
Implementation can be a challenge because a video needs to be loaded as fast as the gesture of the finger. Hence, the app's performance needs to be optimised to handle such interactions.
