VK Speeds Up Video Launch by 6x Even with Weak Internet

The update sharply increased playback stability and reduced delays

VK Video has dramatically accelerated the launch of videos for users with unstable internet. After the update, video on Android starts playing 6 times faster, and in the web version - 4 times faster.

The company also increased the share of successful launches with a weak connection by 16 times. This means that videos are now much less likely to "freeze" and do not require re-downloading.

The effect is achieved through adaptive algorithms that adjust the stream quality to the internet speed and device power in real time. The system analyzes the connection and immediately selects the optimal resolution so that the video starts without delays.

We managed to find solutions that work in conjunction and give a tangible result - the start of the video has accelerated significantly.

Additionally, the web player has been updated: it takes into account the window size and network status, so the first frame appears faster even at low speed.
