Clean Voice Track in AVS Audio Editor

Voice recordings often contain background noises: microphone buzzing, computer humming, outside traffic. Use multiple tools in AVS Audio Editor to make your track sound clearer. They all have presets to keep things simple.

Noise removal

Noise removal polishes up your recording automatically — no need to adjust equalizer bands. With presets and basic parameters you can easily find correct balance by ear.

Step 1. Open your recording and choose Noise Removal on the main toolbar.

AVS Audio Editor removes noises from the entire track by default. If you need to clean up a particular area, click on Get Noise Profile and select it.

Step 2. Choose one of presets and click on Preview. Sounds better? Just choose OK to save the settings.


Set suitable voice frequencies in equalizer automatically with the Vocal preset.


Remove sharp sounds or make whisper audible. Choose one of amplification presets or adjust one manually. Higher values — louder sounds.

Fade In/Out

Presets for fading in and out help mute accidental mouse clicks at the beginning and end of your recording.

Fading is also useful for podcasts where intro music should be played smoothly. Now you can make your voice recording more pleasant. Play with the sound editing tools in the latest version of AVS Audio Editor:

Tilt-shift in AVS Video Editor

What is Tilt-shift

Tilt-shift is a technology that blurs corners of your video. It focuses viewers‘ attention on certain details. Professional photographers will think of tilt-shift lenses, but it is also a visual effect.

When is Tilt-shift used

Video makers may apply the tilt-shift effect to draw attention of the audience to important elements of the image. Look how the American insurance company Allstate used it in their TV commercial:

The message is clear. This video helps us focus on everything we need insurance for — cars, motorbikes, boats, real estate, and people‘s life.

Another way to use tilt-shift is timelapse. Such videos show quick motions on the same place. See the timelapse by Filippo Rivetti with blurred top and bottom. Looks vibrant, right?

Directors use tilt-shift in their films. It can express author‘s emotions and symbolize ideas as in The Social Network (2010) by David Fincher.

Have more ideas of creative tilt-shift usage? Share with us in the comments!

Good news — you can do such videos in AVS Video Editor. Let’s see how.

Tilt-shift in AVS Video Editor

Get AVS Video Editor and follow these steps to apply tilt-shift.

Step 1. Open AVS Video Editor and go to Video Effects -> Special.

Step 2. Find Tilt-shift and drag‘n‘drop it to a line for video effects. Regulate position and duration of the effect.

Here we go!

5 tips for spectacular videos

We bet many of you think that a professional video means high-cost equipment, lighting and software that laymen would learn to use in another decade only. Good news — in AVS4YOU everyone can make any video more Hollywood-looking with any budget or camera!

Just take these five tips into consideration any time you edit footages.

Use colour correction. One of the most important features of a pro video is finding balance of colours.

In AVS4YOU you have several options to play with:

  • Brightness.
  • Temperature.
  • Contrast.
  • Saturation.
  • Gamma.
  • Hue.

A bit difficult for a start? Use the Auto Color Correction option to make the adjustments automatically.

More about Color Correction

Stabilize shaking videos. OK, we don‘t have rails to move a camera, drones directed from smartphones and maybe even tripod. Of course, our videos get shaky sometimes and don‘t just look amateurish, they‘re difficult to watch.

To avoid shaking, stabilize your footage in AVS4YOU.

More about Stabilization

Apply effects reasonably. In AVS Video Editor we have many effects that can decorate your video, but also make it look unnatural, if you overuse them. Try to choose not more than two effects for a scene and make sure they are applicable to the tone of your video.

More about effects in AVS Video Editor

Smooth transitions. You must have seen that in professional videos scenes are rarely changed unexpectedly. Every time you want to change the plot, point of view or landscape, consider applying transitions to carefully bring viewers into another part of your story.

More about transitions in AVS Video Editor

It‘s not only about image. That‘s not to reduce the importance of how the things are shown, but if you choose a right-to-the-point soundtrack, your video will obtain a special atmosphere. A good example is nature footages accompanied by classic music.

And of course, every big masterpiece has titles in the end — in AVS Video Editor you can do it in a few clicks!

More about adding audio in AVS Video Editor

To sum it up, the most important thing is to keep your video harmonious visually and logically. Be careful when choosing effects, follow your inspiration and any video will become more spectacular.

Best editors of 4K videos

Nowadays HQ resolution cameras and appropriate multimedia tools allow you to make professional videos at home without large money spendings. Let‘s see some software for editing 4K videos worth trying in 2021.

Adobe Premiere Pro CC

Adobe always gets into the tops of video editing software — and that is quite logical. With a large set of professional solutions for design, graphics and footages Adobe contributed to the visuals in some notable films, such as Avatar, Deadpool and Terminator: Dark Fate.

With Adobe Premiere Pro СС you‘re free in expressing creative skills using perhaps the richest range of video editing features possible. It runs on Windows and Mac machines and its prices start from $20.99/mo.

Adobe Premiere is certainly the best choice, if video editing is your job or absolute hobby and you have rather deep knowledge of advanced multimedia tools. Otherwise it would hardly be a sensible investment.


+ The richest range of features

+ Windows and Mac supported

+ Automatic backups to cloud

— Expensive for home use

— High system requirements for HQ videos

— Takes time to learn


As you probably guess from the name, iMovie is an editor for high quality videos on Mac devices. It has an intuitive interface and offers all necessary features for polishing up your 4K video and audio tracks.

Good news is that iMovie is really easy to navigate through, you don‘t need an editing degree to use its functionality, there are apps for iPad and iPhone. Necessary tools are always at hand: many stunning effects, transitions, adding text, soundtracks etc. And the best about it — iMovie is entirely free!

All in all, it is a must-have for every Apple device holder. If you‘re not, buying one may be pretty costly.


+ Professional features

+ Easy to use

+ Mobile apps

+ Free on any Apple device

— macOS only supported

— Devices can be costly

Vegas Movie Studio

Another award-winning, easy to use, yet powerful video editing software with a comprehensive set of tools. Fast rendering through CPU/GPU, numerous effects and transitions, detailed work with colors — in fact, it includes most features needed for both amateurs and pros.

The prices start from $49.99 and it is a one-time purchase. But here we see some drawbacks of the basic Vegas Movie Studio plan — pretty fundamental features like color correction and white balance are only available for the Platinum and Suite pricing plans.

Vegas Movie Studio is a good option, if you want some advanced features for 4K, edit videos on a non-regular basis and do not want to pay for a monthly subscription.


+ Professional features

+ Easy to use

+ One-time purchase

— Some features in more expensive versions only

— Rather high system requirements

Wondershare Filmora

Supported on Windows and macOS computers, Filmora is a good and affordable alternative to Adobe Premiere Pro for 4K video editing. It offers many effects, transitions, color matching, hardware acceleration and a clear interface:

Besides, there are a lot of non-editing benefits like easy sharing to YouTube right from the app. The price for a license starts at $39.99, but you can try some features free.


+ Advanced, yet easy-to-apply features

+ One-time purchase

+ Windows and Mac supported

— Some features in more expensive versions only

— Rather costly Pro version

AVS Video Editor

AVS4YOU also offers HD video editing, as well as speeding up the process due to the integrated video cache technology and GPU acceleration. You get access to numerous effects and transitions, basic and advanced editing tools, including color correction, stabilizing shaky videos, trimming, rotating and more.

4K videos in AVS Video Editor

Apart from a video editor, you‘ll have a ready-to-go multimedia suite: video editor, video converter, audio editor and converter, media player, etc. See full list >>

Besides, AVS4YOU constantly has attractive discounts, free updates and support.


+ Features for HQ video editing

+ Easy to use

+ Acceptable system requirements

Every of the above listed apps has strengths and drawbacks, so the right choice will fully depend on your needs, experience and volume of investments. It may sound banal, but there is no one-size-fits-all solution even in big multimedia suites. But we don‘t want to let you go empty-handed!

AVS4YOU colour correction

One of the most important, though often neglected features of truly professional videos is correct colours. We take it for granted in popular films, but poor colour balance is always noticeable when you see it. In this post we give you some tips on how to achieve a good one in AVS Video Editor without attending design classes.

In AVS Video Editor you have several colour correction options to play with:

  • Brightness
  • Temperature
  • Contrast
  • Saturation
  • Gamma
  • Hue

A bit confused? No worries — at the end of this article you will know what each tool is about and perhaps use one in your future video projects! Let‘s look inside.


Although the name suggests adding lights to a footage, it can also darken the image. That is exactly the case, if you want to put some shades and emphasize the contrast.

At the same time, a gentle shift to the right will make warm colours even more impressive. Notice how juicy these bright yellow petals become with +25 brightness?

Of course, you may not prefer too vivid colours. But if the image definitely lacks them, brightness correction can be a good idea.


Artists describe different colours as cold and warm. White and sky blue usually make us think of the snow, ice and cold air, while yellow and orange throw us back to the summer beach and…well, oranges.

In AVS Video Editor you determine the weather in your videos, no more forecasts! Compare 50 degrees above and below zero on this beautiful lake:

Remember that temperature must correlate with the original footage. In other words, even this parameter can‘t make rain disappear from your video!


As you probably can guess, this feature gives a nice contrast between light and dark colour of the image.

Look how moving the contrast slider to the right can make ocean shades deeper and mysterious:

However, contrast is what most laymen often overuse. Make sure your video still looks natural, not like a cartoon (unless it is your plan).


Sometimes colours are too dim and go in disharmony with feelings your video should appeal to. In this case the image will probably need more intense shades.

Look how this parameter may freshen our ocean footage:

Likewise you can reduce intensity of colours, if you find them annoying for viewers‘ eyes — just move the slider to the left.


This effect is quite close to modifying brightness, but using more in-depth change of colours. While brightness makes simple adjustments in a tonal range of a video file, Gamma alters the values of every pixel making the overall image brighter or darker.

Here is a good example of darkening pixels to underline particular colour palette:


Become a true painter by mixing colours in your video! With such impressive shades we can almost turn divers into space travellers:

Remember that the chosen colour will be added, not applied. Example: If you need green palette, and a footage contains plenty of yellow, you need to choose blue (Blue + Yellow = Green). Or the Hue effect may help you create sepia colours.

Before you start

There are also some basic tips to keep in mind:

  • Try and experiment. After all, you can always undo the changes.
  • Avoid excessive colouring. It can annoy viewers and make your footage look artificial.
  • Use Auto Color Correction option to make the adjustments automatically. Sometimes it is not easy to find a good balance yourself and AVS Video Editor can give you an idea.
  • Original video quality is important. That is to say correction is just an editing tool, not an ideal video maker.

Now it is time to show what you can do in the latest version of AVS Video Editor:

AVS Audio Editor balancing

Imagine a music teacher Jack who has a bunch of memorable audio recordings — Jack playing ragtime, his son‘s first guitar melodies and his wife singing Christmas songs. He wants to blend these recordings on one CD and present it on a family celebration.

Jack fused audio files and was disappointed by the result — ragtime music was really loud, guitar melody hard to be heard and Christmas songs were something in between.

In AVS Audio Editor that can be easily fixed by normalizing volume levels of your tracks. Let‘s see how.

Step 1. Open audio files for editing by clicking on the Open button on the Home tab. Find all necessary files and add them to AVS Audio Editor.

Step 2. Switch to the Effects tab and click the Batch button. In the appeared window leave all boxes unchecked except for Normalize*.

Step 3. Click on the Normalize effect and define the volume level. Choose OK and select songs where the effect should be applied.

Preview the result — if everything is right, save your audio file as usual. Now you can listen to music without changing volume for each track!

*The Normalize effect not in the list? Click on the Effects >> button and select Amplitude -> Normalize.
