3. Superior Compression Results
Video compression methods focus on shrinking files as much as possible while keeping the look of the video clear. Current solutions can often achieve around 30% more compression than standard approaches, with the final file size sometimes dropping to a quarter of the original.
For advanced 3D videos, using multi-view HEVC allows for both left and right views to share data. This leads to up to 50% less data usage, while only needing about 10% more time for processing. This allows for efficient streaming and storage of 3D and VR content.
Advances in Modern Video Formats
3D and Multiple View Video Capabilities
New video formats now support 3D and multi-view features. In older methods, a separate video stream was made for each eye when creating 3D videos. This doubled storage needs and made it harder to manage files.
With newer multi-view technology, systems can combine similar parts of each video stream. This can reduce the total bitrate by about 50% compared to the traditional method. According to testing, this modern process only takes about 10% more time than the old way, but it saves a lot of space and bandwidth.
Here’s a simple comparison:
Method | Bitrate Required | Processing Time |
Traditional Dual Streams | High | Normal |
Multi-View (Latest) | About 50% lower | About 10% higher |
These improvements make it easier and more affordable to deliver 3D and multi-view content.
