TimeMachine causes QuickTime Export Error -49

Originator:oliver.drobnik
Number:rdar://11881015 Date Originated:July 16, 2012
Status:Open Resolved:
Product:Mac OS X Product Version:10.8 (12A269)
Classification:Serious Bug Reproducible:Always
 
Summary:

If local snap shots are enabled in TimeMachine you are unable to export lengthy files via QuickTime for apps like ScreenFlow. The export process will go to 100% but instead of completion an error -49 will be reported.

Steps to Reproduce:

- Export a Screencast with over 2 hours from ScreenFlow (from Mac App Store) via the Export Setting

Expected Results:

- Video should be completed

Actual Results:

- Error -49 is reported by QuickTime.

Regression:

This began with Lion when local snapshots where first implemented.

Notes:

There is a forum link of people describing the issue further: https://discussions.apple.com/thread/3398814?start=0&tstart=0

I found that this workaround enabled me to complete the export:
- disable local snapshots
- disable TimeMachine
- reboot Mac

This has been filed a year ago by Screenflow under rdar://10465651 and this has been closed as duplicate of 10378221.

Nevertheless this is an ongoing problem in 10.8.
