Link-Unlink Function in Adobe Premiere
The link-unlink function in Adobe Premiere is extremely useful for lots of reasons. The most obvious is for the syncing of audio and video, but there is so much more that can be done with it.
The link function allows you to link clips together. For example, let's say you shot a video and had a professional sound man who recorded his audio onto a flash drive instead of syncing to the camera. You would have to sync the video and audio in Premiere. This process can be a little tedious because being off by a fraction of a second will be noticed. You don't want to accidentally undo your hard work, so you link the clips together when you're done. This way, if you click on the video, the audio is also selected.
This is also useful when your compositing several layers of video into an effect. Accidentally altering one of the can undo your work, so you link all the clips together to prevent that. It also makes moving those few seconds of video a lot easier because you only need to click one to click all.
By default, audio shot in the camera is linked to the video that was captured with it. But, sometimes you just want to use the audio on a different piece of video. This is where unlinking comes in handy. You select the clip and can choose unlink from the 'Clip' menu. Now, both clips are unlinked, but they're also both selected. Click on something else to unselect them. Then, click on the video clip and delete it. You can now drag the audio to where ever you want it to play.
This only effects the clips as they appear in the timeline. The original synced audio and video is still in your bin if you want to go back to it.
If you recorded the audio on a source that wasn't the camera, and if the camera recorded audio that wasn't really good that you don't plan on using, don't be tempted to unlink that audio and delete it. Instead, you can just turn off the audio for that track. Even though that audio might be poor, it's perfectly synced to the video and could be used as a reference when syncing your professional sound.
Turn both audio tracks on and listen to see if the syncing was done right. If there is a slight echo, then you are not synced and need to adjust the audio's position by a couple of frames.Popular Cameras for High Quality Photos:
