Decide before adding BGM to fireworks videos

When adding BGM to a video of a fireworks display, first decide how much local sound will be left, so that the work is less likely to shake. If you leave the sound of fireworks and people's cheers a little, it is easy to get a sense of realism, and conversely, if you make BGM the leading role, it will be easier to create a summer memory mood. Both are correct, but if you do not decide the axis first, it tends to be a video that does not settle down due to overlapping sounds.

Next, it is important to narrow down which scene in the video you want to be impressive. Whether you want to show the moment of the launch or the beauty of the afterglow, the way the song enters and the peak of the volume will change. If you decide the protagonist of the scene first, it will be difficult to erase the goodness of the image even after adding BGM.

BGM is not a decoration,
If you think of it as a last resort to figuring out what video you want to show, it will be less likely to fail.
  • Decide first whether to keep a little local sound or focus on BGM.
  • Narrow down to one or two scenes of fireworks that you want to show the most.
  • Prioritize the temperature feeling that matches the air feeling of the video over the tempo of the song.

Preparing the video you want to prepare before adding BGM

Rather than putting BGM first, it is better to arrange the length and flow of the image first to stabilize the finish. Fireworks videos are easy to follow similar cuts, so it is easier to match the excitement of the song by narrowing down the scenes to use and then adding music. If you add BGM with a margin that is too long, it will be difficult to understand where to cut later.

Also, if there is a large shake in the material taken by hand, if you check the calmness of the image with a wire like image stabilization before adding BGM, it will be difficult to see even if you add music. Even if only the sound is adjusted, if the image is shaking, the overall perfection is difficult to increase.

    STEP 1
  1. Narrow down to 2-4 cuts and shorten the front and back that are too long.
  2. STEP 2
  3. Look at the shaking and darkness of the image and adjust it lightly if necessary.
  4. STEP 3
  5. Before adding a song, check the tempo by passing through the video only once.
  6. STEP 4
  7. Roughly decide where to start the song and where to turn it down.

CapCut to add background music to a video

CapCut, it is easier to judge if you first create the flow of the video and then put only one song instead of touching the volume finely from the beginning. Since the change of light is clear in the fireworks video, it is easier to organize the atmosphere and reduce the hesitation of editing if you narrow down the song to one song.

For example, in online video editing , you can arrange the material, leave only the scene you want to show, and then add background music to see how the song enters and how the video changes. It is more natural to create the overall atmosphere first and then enter the detailed volume adjustment.

    STEP 1
  1. Arrange the material of the fireworks movie and leave only the scene to be used first.
  2. STEP 2
  3. First, put only one song and see if the whole atmosphere fits.
  4. STEP 3
  5. Set the beginning of the song to just before the fireworks or just before the first highlight.
  6. STEP 4
  7. After watching the video and song once, adjust the volume in detail.

Tips to adjust the volume according to the climax of fireworks

In fireworks videos, it is more impressive to lift only the highlight a little rather than playing BGM at the same volume from beginning to end. If you raise the BGM just a little before the launch or the moment when it opens wide, the excitement of the image and the expectation of the sound will easily overlap.

On the other hand, if you want to leave the sound of cheering or launching, it is better to pull the BGM a little to leave the fireworks. If you want to show a long finish on the video side, you can also consider auxiliary wires that adjust the growth of movement like a speed lamp , making it difficult to worry about the gap between sound and video.

  • Raise the BGM a little before the big fireworks to make it easier to welcome the highlight.
  • Lightly lower the BGM when you want to keep the sound of cheering or launching.
  • Avoid unnaturalness by gently moving without suddenly increasing the volume difference.
  • When changing the elongation of the image, review the peak of the sound together.

The last way to make it memorable without being noisy

If you want to finish the video of the fireworks display memorably, it will be easier to organize it by using one song carefully until the end rather than increasing the number of songs. If you switch to another song on the way, the editing feeling will be easier to come forward than the impression of the fireworks themselves, so it may be difficult to face the video you want to show as a single flow.

Finally, if you gently lower the BGM a little before the video ends, it will be easier to leave a lingering sound. When completed, reduce the volume a little and look back to make sure that all the sounds of lines, cheers, and fireworks are not buried, making it easier to prepare a video that is easy to see.

    STEP 1
  1. The song is narrowed down to one song and the whole atmosphere is aligned.
  2. STEP 2
  3. At the end, it does not stop suddenly, but lowers the sound little by little and leaves a lingering sound.
  4. STEP 3
  5. After completion, look back at even a small sound and make sure that your ears are not tired.
  6. STEP 4
  7. If there is a concern, arrange it in the direction of scraping rather than adding.
