How to merge audio and video clips in Premiere Pro

The goal of virtual is to create an immersive experience and too many times the audio is a forgotten component towards that goal. Since having good audio is so crucial — or at least bad audio is so detrimental — the best practice is to use a third party mic, like a lav mic, to record the audio from interviews that will be played over the video.

Adding this audio to the video is easy when the interview is done off screen, but it can get tricky when you are redubbing audio that the 360 camera has already picked up. Thankfully Adobe Premiere Pro has some built-in tools to help with this process.

The first step in merging the recorded audio clip with the video clip is like with any project, just making sure that all of your material is organized and easily acessible. This will help with the merging of the two clips, especially if you are matching up numerous video clips with one audio file, which is what is being done in the examples laid out below.

Once you have the audio and video clips ready to go you can start by selecting both files by holding the Command button. After they are selected, you can right click to bring up options and then select “Merge Clips.”

This can also be done using the drop-down menus, as shown below.

After you do this a prompt like the one below will show up. You need to be sure to set the synchronize point to audio, so that Premiere will know to process the two clips and match up at the right spot. You also should make sure that the “Remove Audio From AV Clip” is selected so that you only get the higher quality audio from the mic in the video.

At this point, you are essentially done as long as the audio clip and video clips you started with were the same length. But just in case you are dealing with multiple shots and only one audio recording, there is still more that needs to be done.

If you are matching up multiple video clips to a single audio clip you will have to repeat the process above for each individual video clip. You will also have to trim the resulting merged file because it will be as long as the audio clip because it will just relay the video over the adjacent spot.

So you will see a lot of nothing until you trim the clip to only the part where the video is matched with the audio.

You want this:

Not this:

Now you have a video clip with the added benefit of better audio from a mic.



MythBusters Shark Experiment — Story Review

The great thing about the emergence of virtual reality and 360 video is that, along with the completely new content, already present content creators can hop on and give their followers an additional layer of coverage and media. This is exactly what Discovery Channel and MythBusters do in their 360 videos on a shark experiment.

The two videos I watched and am going to review compliment each other in that they follow an experiment through the reconnaissance of the producers to the execution of the actual experiment. Both videos are narrated by the show’s host Adam Savage and he does great to guide viewers while also providing great information about what they are seeing and how it’s all involved in the experiment.

While the two videos are two parts of a whole, I thought it was interesting that the producers tried different things in both to make each capable of being a standalone content item. The biggest difference in the two videos is the placement of the camera. In the first, the camera is held by a diver as he swims past two shipwrecks that have a bunch of sharks swimming around them. The camerawork is really well done and the ride along is really smooth. The second video takes place on the haul of one of the shipwrecks where the experiment is taken place. The stationary placement allows for a nice contrast and a more engulfing view of the sharks swarming around you.

One of the things that seemed a bit new to me in a VR experience like this was how cognitive and upfront with this being a VR experience. Savage pointed out pretty quickly in the first video that he wouldn’t be in this video and at times hyped up the features of 360 videos a little much. This could simply be for promotional purposes, especially in the second video where he talks about how viewers can’t get this immersive environment in any other way, but I wasn’t too bothered by them because it was a really cool experience being so close to underwater shipwreck and a crazy amount of sharks. To me, this seems like the perfect use for 360 videos and while it’s not completely narrative driven, it serves as a really nice complimentary piece to the show.

The blatant statements about this being a 360 video also work because of the many ways they take advantage of it. Savage specifically tells the viewer where to look at certain points to great effect and there is also so helpful and informative labels that pop up throughout the video like in the screencap below. The type of VR experience leads to the viewer wanting to look around without any necessary nudge from the producers, but Discovery and MythBusters does a good job of making fun like in the second video they talk in-depth about a shark that lost half of its jaw in a fishing accident and then Savage lets you know that that shark is currently in the shot so you can try to find him.

This type of content is something that Discovery is no stranger to at this point, as they have a whole VR page on YouTube. And it’s pretty clear that shark content is a great match for this medium as four of their top 10 most popular videos feature sharks in some way. The shipwreck video is actually the page’s number one video sitting at over 15 million views, so I think that is pretty telling in itself.

Overall, it’s hard not to be entertained when Adam Savage and MythBusters is involved. These particular 360 videos add a great extra layer to the experiment and are fun to experience.
