In one embodiment of the invention, encoding multimedia content for use in adaptive streaming systems, includes selecting a first encoding level from a plurality of encoding levels using a media server, determining encoding information for a first stream of video data using the first encoding level and the media server, encoding the first stream of video data using the media server, where the first stream of video data includes a first resolution and a first bitrate, selecting a second encoding level from the plurality of encoding levels using the media server, and encoding a second stream of video data using the encoding information and the media server, where the second stream of video data includes a second resolution and a second bitrate.
1. A method for encoding multimedia content for use in adaptive streaming systems, comprising:
selecting a first encoding level from a plurality of encoding levels using a media server, where the media server comprises a processor and a memory;
determining encoding information at a video encoder for a first stream of video data using the first encoding level and the media server, where determining encoding information comprises determining motion estimations for the first stream of video data;
encoding the first stream of video data using the determined motion estimation results and the media server, where the first stream of video data includes a first resolution and a first bitrate;
selecting a second encoding level from the plurality of encoding levels using the media server; and
encoding a second stream of video data reusing the encoding information determined for the first stream of video data and using the media server, the second stream of video data being independent from the first stream of video data, wherein:
reusing the encoding information comprises scaling the determined motion estimation results for the second stream of video data using the second encoding level; and
the second stream of video data comprises a second resolution and a second bitrate.
2. The method of claim 1 , wherein the first resolution and the second resolution are the same.

7. The method of claim 1 , wherein determining motion estimation includes hierarchical motion estimations using the media server.
8. The method of claim 1 , further comprising storing the first stream of video data and the second stream of video data in a container file using the media server.
9. The method of claim 8 , wherein the container file is a Matroska container file.
10. The method of claim 1 , further comprising storing the first stream of video data and the second stream of video data in separate container files using the media server.
11. The method of claim 1 , wherein encoding the first stream of video data and encoding the second stream of video data utilizes scalable video coding.
12. A media server, comprising:
memory storing multimedia content comprising a source video; and

select a first encoding level from a plurality of encoding levels;
determine encoding information at a video encoder for a first stream of video data using the first encoding level, where determining encoding information comprises determining motion estimations for the first stream of video data;
encode the first stream of video data using the determined motion estimation results, where the first stream of video data includes a first resolution and a first bitrate;
select a second encoding level from the plurality of encoding levels; and
encode a second stream of video data reusing the encoding information determined for the first stream of video data, the second stream of video data being independent from the first stream of video data;
wherein reusing the encoding information comprises scaling the determined motion estimation results for the second stream of video data using the second encoding level; and
wherein the second stream of video data includes a second resolution and a second bitrate.
13. The media server of claim 12 , wherein the first resolution and the second resolution are the same.
14. The media server of claim 13 , wherein the first bitrate is lower than the second bitrate.
