Not finishing execution on PowerShell

[corujoraphael]

Hi team,
I m not sure it s an issue, i probably might do something wrong, but here is my question.
When I run "Natron -b .\LowerThird_01.ntp" in PowerShell everything works fine, but the script doesn't finish the execution. It gets blocked on the last message waiting for some action. The last lines of process feedback are:

Write1 ==> Frame: 297, Progress: 99.0%, 1.9 Fps, Time Remaining: 1 seconds
[libx264 @ 000000000a1be9c0] non-strictly-monotonic PTS
Write1 ==> Frame: 298, Progress: 99.3%, 1.9 Fps, Time Remaining: 1 seconds
[libx264 @ 000000000a1be9c0] non-strictly-monotonic PTS
Write1 ==> Frame: 299, Progress: 99.7%, 1.9 Fps, Time Remaining: 0 second
[libx264 @ 000000000a1be9c0] non-strictly-monotonic PTS
Write1 ==> Frame: 300, Progress: 100.0%, 1.9 Fps, Time Remaining: 0 second
Write1 ==> Rendering finished

Do you have any flags you can put to stop waiting?
