|Summary||0000167: Automatic resynchronization of the video and audio tracks of a timeline clip|
|Description||I have searched the Cinelerra menus and manuals and I can't find if there is an automatic resynchronization option between the audio and video tracks of a timeline clip.|
Here when I talk about synchronization I mean the relative position of the sound and image, as it was (and still is) on the source media from which a timeline clip originates.
Situation: It happens that voluntarily, by wrong operation or by an operating bug, the sound of a timeline clip is no longer attached to the video track exactly as it was on the clip source.
When later on, we want to bring the relationship of the sound and image of this clip back into "synchronization" such as on the source media, sometimes it is easy but other times it is more difficult. However, the reference of this synchronization still exists on the source.
Would it be possible to create an option to automatically resynchronize the audio and video tracks of a timeline clip, as it is still on the source media, either by automatically moving (slip) one or both audio tracks according to the image or vice versa, moving (slip) the image track according to one of the original sound tracks?

|Maybe we can find a better way. Marking as related to issue 0000165.|
|Well, after more tests, my procedure doesn't seem to work every time.... It was too simple....|
Actually, I found a simpler method:
Simply select the clip (from the timeline) that has lost its synchronization, then use the context menu "Find in resources". If the number of clips extracted from this source is not large, it will be possible by Src Target to determine and display the segment concerned in the Viewer. Then simply use the "Overlay" Viewer command to easily replace the unsynchronized track of the selected timeline clip.
Here it is clear that an improvement of the "Find in resources" function to more easily identify the right segment of the source would be useful. This could be colored differently on the Src Target screen.
From my understanding of what GG has explained to me, if not using "align edits" because it is not simply a matter of realigning the edges, then the easiest method to synchronize is with the use of "Show edit".
You would right mouse click the Video track and record the "Start Source" and "Start Project" numerical values.
Then do the same for the Audio track. You should be able to subtract the numbers and use them to realign between the 2 with the aid of the zoombar Selection start time values.
Does this solve synchronization easy enough? GG thinks so but I am not so sure.
