 i  free download      More Info  

A typical video quality enhancement software for old videos works to improve video quality through the following features.

• Perform color correction
• Remove noise
• Filtering to correct contours
• Perform frame interpolation, including deinterlacing
• Remove scratches
• Perform image stabilization

As you can see, video quality enhancement software performs a variety of correction processes to improve image quality. However, due to the nature of video data, these processes do not essentially improve image quality. In other words, these various corrections are actually "processing to make the image quality look better.

DVDFab Video Processing AI differs from conventional video enhancement software as described above in that it uses AI technology to perform processing. It uses advanced machine learning to improve the quality of older videos, allowing them to be played back more clearly than before.

This is not strictly speaking an actual video quality improvement, but you will feel a similar effect. Another nice feature is the fully automatic video processing. This means that even beginners can easily improve video quality without the need for complicated parameter settings.

With DVDFab Video Processing AI, you can upscale low-resolution videos, such as old home videos, to 4K level. Increasing the resolution of your videos is something you should consider if you want to enjoy your precious old videos for a long time.
 

Video Enhancer 3: Video Enhancer

Topaz  Video Enhancer is one of the leading free software for video enhancement, and both Windows and Mac versions have already been developed, so users who mainly use either can use it.

Video Enhancer offers two modes, "Simple" and "Advanced," each with different processing possibilities.

• Simple" mode: This mode is mainly used to enhance video quality through resolution-enhancing functions. This mode is for people who do not need advanced processing.
• Advanced" mode: In addition to the high-resolution processing function, a function called "VD Filter" is available. This mode is effective for those who want to improve video quality other than resolution at the same time.

Thus, the two modes differ in the range of possible video processing. In "Advanced" mode, "VD Filter" with the following functions is available, so you can enjoy higher quality videos by utilizing this function.

• Block noise/noise removal
• Color tone correction
• Shake Correction
• Sharpening

One drawback of this video enhancement software is that there is no Japanese version.

Another disadvantage is that it is not a video editing software, so it does not have many functions other than those related to video quality improvement. However, the high-resolution processing functions in particular have been well received by users. Anyway, if you are looking for a software with good video quality enhancement features, it is worth a try.

Video quality improvement software 4: AviUtl

AviUtl is a free software that is immensely popular as video editing software. Unfortunately, the supported OS is Windows-only, but it has the excellent property that its functions can be expanded by installing plug-ins.

AviUtl is often used for video editing, but it can also improve video quality. For example, by installing plug-ins that can perform the following processes, it can be used as a high-definition software to improve video quality.

• Deinterlacing
• Color correction
• Noise Removal
• Sharpening

Since "AviUtl" is used as video editing software, the following processing and video editing can be performed in addition to image enhancement.

• Subtitle editing
• Mosaic processing
• Adding transitions
• Resizing and adjusting aspect ratio
• Video trimming
• Rotating and flipping
• Video Cut Editing
• Outputting Video

As described above, "AviUtl" can perform all major video editing tasks except for some special ones such as DVD authoring. If you plan to do serious video editing, "AviUtl" is a good choice as a high quality video editing software.

However, because of its high scalability, "AviUtl" requires complicated work in terms of installing the main unit and plug-ins. It is recommended to start using "AviUtl" after fully understanding its disadvantages, since a certain number of users fail in the initial setup.

Recommended free apps to improve the quality of old videos

Next, we will also introduce recommended free apps and video high quality conversion sites for videos on your smartphone.

Please note that only software that is compatible with both iOS and Android is discussed in this article, so both iPhone and Android users can read on with confidence.

Free Video Enhancer 1: Remini

Remini is one of the leading image quality enhancement applications for smartphones; it is compatible with iOS and Android devices and can be used on a wide variety of devices.

Remini is best known as an app that can enhance photos, but it can also handle videos with its "Video enhance" feature.

One of Remini's unique features is its use of AI to enhance the app's image quality; AI technology allows for clearer portrayal of people, landscapes, and buildings, making, for example, blurry, low-quality videos easier to view.

The following simple steps are easy to use for high quality image enhancement and video editing.

1. Launch the Remini application and open the top page.
2. Select the video editing process you want to perform
3. Upload the video you want to process and you can correct the image quality.

On the other hand, the following are some of the disadvantages of Remini

• Supported language is English only
• The free version can only be used up to 5 times a day
• Large videos take a long time to be processed for image quality enhancement

The fact that there is no Japanese version and you have to use the English version is a disadvantage. However, as we have already mentioned, the procedure for using Remini for image enhancement is very simple. Most people should be able to operate it intuitively, even if they do not understand the English well.

In addition, the free version has a limit on the number of times you can use it per day, so people who use it frequently may feel stressed. However, the limit can be removed by subscribing to a paid plan, so if you are not satisfied with the service, you can reduce the disadvantages by paying a fee.

Considering that this is a highly functional free application with AI processing, it can be said that the advantages outweigh the disadvantages. If you are looking for a free high-definition application, please give it a try.

Video Enhancer Free Software 2: CapCut

CapCut is a free app with a full range of video editing functions. Like "Remini," it is compatible with both Android and iOS, but note that it may not work properly unless Android is 5.0 or later and iOS is 11 or later.

CapCut has excellent output features and is capable of outputting high quality video. Although it is a smartphone app, it supports 2K and 4K levels of resolution, so you will be able to make your videos relatively higher resolution than if you use other apps for output.

In addition, since CapCut is a video editing app, a wide variety of video editing functions are implemented as follows.

• Video cut editing
• Reverse playback and speed change
• Filter processing (beauty face filter)
• Transitions
• Design editing using templates

In this way, "CapCut" can perform advanced video editing that is as good as PC software, so it can be said to have very high functionality among free video editing applications.

However, video editing is the main function, and with the exception of the output function, the functions related to image quality are not that extensive. Therefore, it is suitable for those who often perform video editing, but it is recommended that those who mainly use the high-definition function check in advance whether it is suitable for the purpose of use.

Free Video Enhancer 3: Adobe Spark Video

Adobe Spark Video is a highly functional free application suitable mainly for editing and creating videos. iOS and Android, as well as OS X and Windows, are supported, so if you like using it on your smartphone, you can also introduce it to your PC.

Since Adobe Spark Video is an app for video editing and creation, it does not offer a full range of functions to directly improve image quality, such as filters and effects. Therefore, in some cases, it may not be suitable for those who want to thoroughly focus on improving image quality.

However, using Adobe Spark Video templates and themes for videos has the advantage of enhancing resolution. In other words, by utilizing templates and themes, videos can appear higher quality, which is practically the same as achieving higher image quality.

This feature makes Adobe Spark Video a good choice for use as a video quality enhancement application.

In addition, Adobe Spark Video's templates and themes allow anyone to create well-designed videos. Since edited videos can be saved to the camera roll or uploaded to various video posting sites and social networking services, sharing and publishing is also easy. Japanese-language support makes it very easy to use.

Adobe Spark Video is basically free to use, although some content is available for a fee. You can try it out at no cost, so if you have any doubts, it is a good idea to download it once.

There are also many video quality improvement sites, so please refer to the following article [ Video Quality Improvement Sites]!

Tidbits of information about video quality:

Factors affecting image quality: Frame rate, bit rate, resolution, brightness, and contrast are said to be factors affecting image quality.

Frame rate: This is the number of frames of still images used per second in a video, expressed in units of fps (frames per second). The higher the frame rate number, the smoother the motion of the video.

Bit rate: This is the number of bits transferred per second, expressed in bps (bits per second). Videos with a higher bit rate transfer more information per second, resulting in better image and sound quality.

Resolution: is the fineness within a single unit size range of an image, expressed as the number of dots per inch, using the unit dpi. For videos of the same size, the higher the resolution, the greater the number of pixels that make up the image, and the finer and cleaner the video screen.

Brightness: This is the brightness of the video screen. If the video screen is too dark, it is difficult to see the details of the video.

Contrast: This is the difference in brightness or brightness/darkness ratio between the darkest and brightest areas of the screen. The higher the contrast, the greater the difference between brightness and darkness, resulting in a clearer video.
