How To Use The TimeBolt Extension

In this step, we're going to take a look at how to set-up the Timeline to use the TimeBolt Extension. We've broken the step down into the various permutations of files that are available.

• Single Audio Track

As shown in the image above, we drop the audio file (.wav, .aac etc) in the Timeline Sequence and align it to start from zero seconds.

Steps

1. Open the audio file in TimeBolt and adjust the cuts to your liking.
2. Save .json from TimeBolt.
3. In Premiere Pro, select the clip you want to apply the .json file to with your mouse.
4. Open up the TimeBolt extension from Window > Extensions > TimeBolt Extension.
5. Click on the Apply JSON File button and navigate to the .json file saved from TimeBolt.
6. Click open and bam! Your cuts are ready.

• Single Video Track linked with Single Audio Track

As shown in the image, we have a video file which has a single stereo audio track. Again, this file is dropped in the Timeline Sequence at zero seconds.

Steps

1. Open the video file in TimeBolt and adjust the cuts to your liking.
2. Save .json from TimeBolt.
3. In Premiere Pro, select the clip you want to apply the .json file to with your mouse.
4. Open up the TimeBolt extension from Window > Extensions > TimeBolt Extension.
5. Click on the Apply JSON File button and navigate to the .json file saved from TimeBolt.
6. Click open and bam! Your cuts are ready.

• Single Video Track linked with Multiple Audio Tracks

As shown in the image, we have a video file which has multiple stereo audio tracks. Again, this file is dropped in the Timeline Sequence at zero seconds.

Steps

1. Open the video file with multiple audio tracks in TimeBolt and adjust the cuts to your liking.
2. Save .json from TimeBolt.
3. In Premiere Pro, select the clip you want to apply the .json file to with your mouse.
4. Open up the TimeBolt extension from Window > Extensions > TimeBolt Extension.
5. Click on the Apply JSON File button and navigate to the .json file saved from TimeBolt.
6. Click open and bam! Your cuts are ready.

• Multiple Synchronized Video / Audio Files

CASE #1

As you can see in the image, we have a Timeline Sequence set-up with files from a multi-camera project.

Before we dive into the steps, we'd like to point out a few things about this particular structure. Each video track corresponds with the audio track with the same index. Ex: Video Clip in V1 track and Audio Clip in A1 track are from the same file and Video Clip in V2 track and Audio Clip in A2 track are from the same file and so on. The Extension will give unstable results if this convention is not followed.

The obvious next question is—what if I have a Master Audio File (.wav, .aac etc)?

In that case you'd have to leave the video track empty as shown in the image.

CASE #2

Another case could be where, you have an audio file along with all your multi-cam files but that audio file is not your Master Audio file. In that case, you can just drop that clip on the highest audio track. You can do this for multiple audio files.

CASE #3

Please Note

Always remember that your Master File or the file that you TimeBolt for cuts should start from zero seconds in the Premiere Pro Timeline and is preferably the longest file. The saved .json file doesn't care whether it originated from a video file or audio file. It is just a collection of timestamps and can be applied to any clip—video or audio.

Steps

1. Open the Master file (video or audio file) in TimeBolt and adjust the cuts to your liking.
2. Save .json from TimeBolt.
3. In Premiere Pro, select the first clip you want to apply the .json file to with your mouse (start from V1-A1).
4. Open up the TimeBolt extension from Window > Extensions > TimeBolt Extension.
5. Click on the Apply JSON File button and navigate to the .json file saved from TimeBolt.
6. Select the next clip and similarly apply .json to that clip.
7. Repeat Step 6 until .json is applied to all cuts.
8. NOTE: the cut footage is applied to the end of the timeline in Premiere. Just delete these clips. 
9. Click open and bam! Your cuts are ready.

These are the set-ups that the TimeBolt Extension supports right out of the box. You remove silence so fast, it almost feels like magic. If you're going for a more complex set-up, you can always create a new sequence, apply the .json file on the tracks in that sequence and then copy the cuts back into your main sequence.
