| Title |
IS13 wmv to video format-X Migration Results in Out-of-sync Sound and Video |
| Detailed description | SB does not want to keep the windows media video files for preservation. Earlier attempts at migration using ffmpeg failed on some files. Some of the migrated files had sound and video out of sync. |
| Scalability Challenge |
4 TB collection windows media video (wmv). Number of files ~ 14640. Detecting the out-of-sync files manually is resource demanding. |

Evaluation
| Objectives | Scalability, automation |
| Success criteria | The workflow that migrates the files also performs a QA, that convinces us the migrated files do not have out-of-sync errors, and with reasonable performance. |
| Automatic measures | * process 20 files per hour per node * 99% of files pass automatic QA test |
| Manual assessment | * any 'failed files' should be checked. They should not be 'false positives' (successful migrations with no out-of-sync errors). |
