I cannot see 09:13:53 on the picture, while video contains that timestamp and not the bird. Are you sure about the picture and the timestamp? Sometimes stream and substream may be not in sync, so you may see such weird recordings. Increasing pre- and post-capture may help, as well as adjusting camera's encoding to have all key frames or set it to CBR. Also you can try to enable |

And I mean the timestamp that camera prints on the image, not motion's timestamp |

That's my problem, the timestamp is not readable. |

Have you looked to see if there were multiple movies created during the event? Either in the log or in the directory. Or that the movie names are not overlapping and over writing each other? i.e. A second movie during the last part of the event is not overwriting a movie created during the first part of the event. Based upon the camera timestamps and playback duration, it looks like all the frames were recorded so just not sure if the bird was there during a time before or after this movie. (Recall that the "best" picture per event and there can be multiple movies per event. So the "best" image is not going to be in every movie created.) |

No, there's only one movie, also only one recording in the logfile. |

what is your camera model? does it allow changing the codec or the video encoding params? |

We will need to see a full log at the INF or DBG level to understand it. |

Hm, is this realy helpful? Cameratime 17:21:51, Motion-Time 17:22:01 |

This provides a lot of insight into the issue. The important bits to the log are not only this but also the startup where we can see the version, parameters and messages around the starting of the cameras. |

Looks like you also could have some other things going on. First, probably should stop and disable the service. Then start Motion in a terminal and look at the log and verify that the Next, I see that the option For the netcam options, I noticed that you used As for the cause, it could possibly be duplicate instances running or possibly a sync issue between the regular |

Hello Mr-Dave, Also setting daemon to off is not the way to go. The But it is still running: For now, I will start motion in a terminal and see if my problem persists. |

Yea, I've been thinking about this one for the last week or so. This is sort of a bug as well as an enhancement. Enhancement by virtue of it has always had this issue. Bug because it isn't staying in sync with the high resolution. I would say that first you should add a As for long term resolution, I have an idea to solve this using an opaque on the packet to capture extraction time and compare after it comes out of decoding and then perhaps speed up the capture/decoding but I've not seen any real life examples of it. My guess is that it would be complex/significant and tbh not even sure it is possible. |
