4. First, a little bit of history

5. The Architecture of the old system
Video CMS
(StoryLog)
NYTimes CMS
(Scoop)
Internal
Encoding Cluster
Internal Storage

6. The flaws

7. The Flaws
1. The whole process relies on a filename
2. Several watch folders
3. Unstable transcoding
4. Hard to scale
5. Two CMSs are required to publish a video.

8. The Flaws
1. The whole process relies on a filename
2. Several watch folders (hard to maintain)
3. Unstable transcoding (proprietary software)
4. Hard to scale (cluster in-house)
