Synchronisation between Video and Annotaions

Synchronisation between Video and Annotaions
We started using ELAN for a backtranslation. After checking with our consultant that he was happy with the way we had done the first few sentences we wanted to continue. Now we find that we cannot get the video lined up with the end of the last annotation unless we start it running from the beginning. Also if we try to use any of the buttons which should enable us to jump from one place to another the video jumps to something quite differnt and even the annotations are not correct.
It is interesting to note that the correct time is indicated but the wrong frame is visible. We are using Windows XP SP3, ELAN 3.7.2. It doesn´t matter if we are useing Quicktime or not also it is independent of the video codec (mpeg 1, mpeg 2, mov).
Has anyone else this problem?

Re: Synchronisation between Video and Annotaions
Even though this behaviour seems to be independent of the media player in use, it would still be interesting to see what information is available in the log file (<user_home>\.elan_data\elan0.log). E.g. after opening and navigating through an mpg-1 file and then exiting ELAN. Especially the part after "Filters in the filter chain: " (in case of the Windows Media Player) would be of interest.

Hallo Han,
I have an interesting solution. I deinstalled quicktime, restarted the computer and the problem was solved.
In the Elan log there are for the m2v file no exceptions but for the m1v file i found this
Filters in the filter chain:
index: 0 name: Video Renderer
pin: 0 name: VMR Input0
index: 1 name: MPEG Video Decoder
pin: 0 name: Input
pin: 1 name: Output
index: 2 name: MPEG-I Stream Splitter
pin: 0 name: Input
pin: 1 name: Video
index: 3 name: file:///F:/Ruth_Backtranslation/Sabine_v2_5.12.08.m1v
pin: 0 name: Output
Aspect Ratio: 1.3677486
Millis per Sample: 40.0

Clean up media player...

Hope the problem won´t come back.

Re: Re: Re: Synchronisation between Video and Annotaions
Ah, thanks for reporting this exception. This one has nothing to do with media playback but with the "Recent Files" list in the File menu. I'll see if I can fix this bug before the next release.
