In the life of every video editing lover, there comes a time when it's time to learn not only video effects, but also audio - how to change audio track... And sometimes it is a necessity, if the sound in the video leaves much to be desired and needs to be replaced. Or you want to add a special piquancy or zest to the video sequence, for example, the effect of an echo, an assembly hall, the feeling of a room, and more.

Sony Vegas video editing software is like no other suitable for this type of work, moreover, even a beginner can easily master it.

So, our today's lesson will be devoted to editing audio tracks in Sony Vegas. And we'll cover four basic basic tricks.

1. Removing and replacing audio.

This technique is needed in order to replace the existing audio with something else (for example, instead of drunken trills of guests at a wedding, substitute Verka Serduchka's hit or simply delete it.

Open the project, load the desired video fragment into it and drag it to the work area. If you drag this video around the work area with the mouse, you will notice that both video and audio go together inseparably. And this does not depend on whether you drag the mouse for a piece of video or for a piece of audio.

Accordingly, if you try in such a case with the key DELETE delete the audio track, then the entire movie will be deleted along with the video. To prevent this from happening, it is necessary to "break" the video and audio. To do this, click on the video and press the " U ". Then, dragging the video with the mouse again, you will see that it is already moving separately from the audio track. After that, we simply delete it and, if desired, put another one.

2. Change the sound level.

This technique helps to make sound jumps from loud to quiet, when at a certain moment the sound needs to be muted or, on the contrary, raised its level. So, for this we go to the menu items Insert ->AudioEnvelopes ->Volume or use hotkeys Shift + V.

Then we return to our video, or rather to the audio track that belonged to him. Double-click the mouse to place marks in the places where we will adjust the sound.

Then, by pressing these marks and moving them, you can raise or lower the level of sounds. Listen to what happened, it might be funny.

You can also make an effect that I call “ Left ear - Right ear". It assumes the sound of audio in the left speaker, then in the right. To do this, go to the menu items Insert ->AudioEnvelopes ->Pan or press the burning keys Shift + P.

Again, on the audio track, put marks in several places where we want to apply the audio effect.

And, as in the previous case, using the labels, we adjust where the audio will fall to " left ear", And where - on" right ear».

3. Special audio effects

Sony Vega s has its own set of audio effects that will help to embellish the sound of the video. To find them, go to the menu items View ->Plug-inManager .

A window opens to our eyes with a variety of audio effects for every taste.

To use one of them, you need to drag the selected one onto our audio track with the mouse and set the necessary characteristics.

4. Slow-motion sound

To "stretch" the audio sound (in English - slowmotion), you need to select the desired video, if necessary, "cut" the piece that will be edited (for this, the cursor clicks on the video in the place where you want to make the "cut" and click key " S"). And then the desired piece is pulled to the side.

And then we hold down the key CTRL and drag the video by the edge, thus stretching it. So much for slow motion and sound.

The dubbing process consists in extracting the existing audio track from the video clip for its subsequent removal and replacing it with your own. This can be done in a variety of ways. Some methods are used to replace background music or sounds to add new sounds. Many YouTube videos use dubbing to overlay a new voice track into an existing video clip, such as commercials. Some musicians use dubbing in a different way, they replace the low-quality sound of a live performance with a better one or a different version of the sound.

The dubbing process is fairly easy to do in iMovie for macOS, but it can get complicated depending on how well you need to get the job done.

Removing and replacing audio in iMovie

First you need to delete the old audio track in the video clip for this you need to create a project and drag your video clip there, which already includes the audio track. In the iMovie app on your Mac, create a new project by clicking on the + icon in the upper right corner. After that, in your project library, find the folder containing the video you want to use or do a search in your library. Find a video clip and then drag it to the iMovie timeline tab.

Now select this clip and then from the menu bar, choose the "Modify" command. Click on "Detach Audio" from this menu. (Alternatively, you can simply right-click a clip and select that command there, as in the screenshot.) Note that iMovie has split this clip into two independent files: audio and video, so you can freely edit and manipulate them separately.

After that, you can very easily delete the original audio track and drag your own audio track there. Click on an audio track in iMovie and then Delete on your keyboard. You can then use the iMovie app's audio library to drag and drop a new audio file there, or import your own file from the Finder.

Drag the new sound file to the bottom panel below the video clip and make sure it is aligned properly to avoid pauses. Play the entire clip in the iMovie app and you now have a new video clip with a new audio track.

Combining a newaudiotracks with the previous audio trackin iMovie

This tactic is applied to a variety of needs. Merging a new audio track with a previous one isn't just dragging and dropping a new audio track. Correct alignment of two audio files will help to achieve the correct sound for all audio tracks and maintain consistency and continuity of sound.

For example, let's say you recorded a video of you singing a song. In general, everything sounds good, except for a small snippet. Therefore, you recorded another take, in which you corrected all the mistakes that took place in the first take. Using the replacement process, you insert into the video clip only that part of the audio track that fits exactly with the poor quality fragment and now the entire audio track sounds great. Thus, you have fixed all your mistakes in the sound design of the video clip.

The alignment process requires special, proper alignment of both audio tracks plus proper alignment with the video sequence so that your mouth movements align correctly with the audio track.

As in the previous method, first drag your video clip into a new project, and then right-click on the timeline to select an audio track.

Note the two parallel audio tracks for one video.

Now, instead of deleting the audio track, you need to save it. Then you need to find either another video clip with soundtrack, or just a separate audio file that you need to use in the first video. Most likely, both tracks will be the same in terms of duration, but with slight variations in sound design. If you drag a full-fledged video clip onto the timeline, you must first select the audio track in it, and then delete the video component. If it's just audio, all you have to do is drag and drop the audio file onto the timeline.

Place the new audio track under the old audio track. Pay attention to the similarities in the vibrations of the sound waves, so you know exactly where and how to place the new audio clip. Both audio clips should match each other as closely as possible and have only minimal differences.

Determine where you want to stop the sound of the first soundtrack and where you want to sound the second soundtrack. Then, you need to split both clips at the same point in the timeline. Do this by holding down the Shift key and selecting both audio tracks, then position the cursor at the split point. Click the Edit button in the menu bar and select the Split Clip button. (Or press Command + B.).

Determine the second split point on the timeline in the same way. You may need to play the audio track several times to determine the time interval that we want to replace. Choose the split area on the track where it is easiest to mix audio tracks, that is, the joints should fall on the area of ​​the minimum audio level. Now, you should have two audio files, each with two timeline separators.

Delete the highlighted time slot in the upper audio track, and then drag the highlighted time slot of the second audio track from the lower file into the upper audio file. For best results, you need to align the audio tracks as accurately as possible.

You may need to change the sound parameters and adjust the audio clips to make them sound right, so listen to them several times. After achieving the desired effect, you can remove any unnecessary audio fragment from the second audio track.

As you know, files with the extension mkv is a special multimedia container for storing video, audio paths and subtitles. She is Matryoshka. Below will be described how to work correctly with audio tracks.

It often happens that there are several audio paths and subtitles in a container, and some of them are not needed. For example, roads with an unfamiliar language or several Russians. Or another option, when the sound road has the format dts, which is not always reproduced by "iron" players. It can be recoded to ac3.

I will describe the most optimal, in my opinion, actions to accomplish these tasks.
You only need two programs.
The first one is Mkvtoolnix for working with mkv containers.
The second - Xilisoft Video Converter Ultimate... Besides coding dts v ac3 has many other useful features.

Take the once popular Slumdog Saints as an example.
Launch mkvmerge GUI from the kit Mkvtoolnix
Choosing a movie and getting something like this:

In addition to the video and subtitles, the container contains four more roads. English, two Russians and a road by Goblin. Here she is just needed. Remove the checkboxes from unnecessary elements, select the final path and the name of the reassembled container and click Start muxing.

After mixing is complete, the new container looks like this. Video and one audio track.

Now it can be recoded into ac3.
Launch Xilisoft Video Converter Ultimate... Add a file, in the Profiles tab, select ac3 and the path to save. Also on the right side of the program, you can change the settings for the encoded track.
We press the red button at the top and wait.

It turned out to be a separate track ac3... Now you need to replace the track with the extension with it. dts... To do this, open the mkvmerge GUI again, select the file mkv with one track dts and add the track with the add button ac3, while from the track dts respectively, uncheck the box.

You ask why all this was needed?
The original file with all tracks weighed 6.56 GB, the final file was 3.78 GB. In addition to the fact that it takes up less space, it can be copied relatively quickly to a USB flash drive and viewed from a device that does not support sound in the format dts(for example, SAMSUNG TVs of the sixth series of 2009, which even the new firmware did not help to learn to read dts).

It is not recommended to use mkvmerge versions higher than 4.0.0. This is especially true for owners of Samsung TVs of 2009 release. (2009 is the B in the model name. For example LE37 B*****) Most of the reassembled containers refuse to run on the built-in player of the above TVs.

UPDATE2:

And how to pull out separate subtitles or an audio track? It's simple. To do this, you need a program MKVExtractGUI... It must be placed in a folder with Mkvtoolnix.

Everything is intuitive here: select a file, an output folder and check the boxes to mark the files needed to extract from the container.

The wonders of video editing are available to everyone today, and for this it is not at all necessary to go broke on expensive programs from Western developers. The Russian analogue of Pinnacle Studio makes it much easier to edit videos: its interface is clear for every user. A large number of lessons on the site makes it easier to master the editor, even for absolute beginners in editing.

If there are noises in the source material or the voice acting does not meet your wishes, the analogue of Pinnacle in Russian will allow you to replace the sound with video. This task is surprisingly simple and can be completed in a matter of minutes. Follow this instruction and in just a few steps you will get the desired result.

Step 1. Download Pinnacle and install it

From the main page of the site, go to the "Download" section, enter your e-mail and click the "Download now" button. In the letter that will come to the specified email address, click on the link to download the installation distribution. The trial version of the Russian version of Pinnacle Studio is 52 MB in size, and even at low Internet speeds, it downloads very quickly. After downloading, open the file and install the program on your hard drive, and then launch Pinnacle.

Step 2. Create a project

After starting the program, you will see the main menu. Here you can choose in which mode to work further. Since we are faced with the task of replacing the sound in the video, we select the top option "New Project". In the next dialog box, adjust the aspect ratio of the video - the easiest way is to select the "Set automatically" option. Click "Apply" and go to the next step.

Step 3. Add video to the project

At this step, you need to open the file with which you want to work next. It can be selected through the built-in file manager by dragging it from the folder to the temporary panel below, or by clicking directly on the "Add video" icon on the bottom panel of the program.

After the file is added, do not rush to move on. Pinnacle in Russian automatically adds transitions at the end - this makes it easier to work with editing, but when processing single videos, this function is not always needed. To disable it, right-click on it, and in the menu that opens, select "delete transition". After that, you can move on.

Step 4. Replace the audio track

There are two ways to replace sound in video with music or pre-recorded speech in this program. The first one involves working with added files and allows you to set the sound for each fragment separately. The second one adds voiceovers to the entire video. And since we are now considering replacing the sound on the same file, both methods will give the same result.

Method 1. Working with the file

Go to the "Edit" tab and select the "Replace Sound" option. By clicking on the "Add Audio" button, you can use one of the built-in tracks or select a file from your computer. Once added, you can trim it to fit the length of the video you are working with. To do this, click on the scissors icon and move the black markers to the desired positions. Remember to listen to the result to make sure you are not mistaken.

Method 2. Working with a complete project

Go to the "Music" tab and click on the "Add Music" button. The options for selecting and cutting the duration of the voiceover are completely similar to the previous method, with the exception of an important point. In order for the selected track to completely replace the standard audio track in the video, it is necessary to uncheck the "Add music to original video sound" option.

Step 5. Save the processed video

The final step is to save the work done. Go to the Create tab and select the appropriate save option. allows you to save video in any of the popular formats, burn it to DVD or optimize it for viewing on mobile gadgets or publishing on the Internet. After you decide on the choice, the Russian analogue Pinnacle will process and save the video, and you can enjoy the result.
