If you use a live captioning service, the caption file usually starts when the first person speaks. This often doesn't match your video timing because you might have gone live 10 minutes before anyone talked. In this case, your first caption shows 00:00:00.00, but the actual dialog in your video starts at 00:10:00.00. Now, everything is out of sync.
For cases like this, you can use the Shift caption timing feature to easily and quickly sync your captions with the video.
Shift caption timing
First, you find the segment that marks the beginning of the file that is out of sync:
- If the whole file is out of sync, then pick the first segment in the file (e.g., the actual dialog in your video starts at 00:10:00.00 - pick the very first segment in the caption file and shift it to match the 00:10:00 mark in your video).
- If the sync problems don't appear until later, you select the segment where the problem begins. From this segment onward, all segments will be shifted by the same amount of time.
Steps:
1. Open the video > click Captions.
2. Click on at the right edge of the segment and click on Shift Timing.
This opens the pop-up window with the player.
3. Using the video player, find the point in the video when you want that caption to start. If the caption is "Hello, welcome to the meeting" then find the point in the video where you hear "hello". That time will now be displayed in the time field.
4. Click on Shift Captions Segments.
All other caption segments after this segment will also be moved by the same amount of time.
