"What is the best online video converter to upscale low quality 720p video to high definition 1080p?"
The human eye can only process 2160 pixels in a horizontal direction, making it difficult to detect subtle differences in high-definition video resolution.

The perceived quality of a video depends on the viewer's visual acuity, attention to detail, and cognitive biases.

The International Telecommunication Union (ITU) recommends a minimum video resolution of 1280x720 pixels for a 16:9 aspect ratio in SD resolution.
To achieve HD quality, a minimum resolution of 1920x1080 pixels is required.

AI-powered video converters can improve video quality by adjusting settings such as bitrate, framerate, and compression ratio.
However, the effectiveness of these adjustments depends on the original video quality and encoding settings.

The primary difference between MPEG4 and H.264 video compression is the encoding method, with H.264 providing better compression efficiency and higher video quality at the same bitrate.

When converting low-quality video to HD 1080p, it's essential to consider the video's original frame rate, resolution, and bitrate to ensure accurate upscaling and prevent artifacts.

The resolution of a video is not the only factor contributing to its quality.
Other factors like bitrate, framerate, and color depth can also affect the video's overall quality.

The human brain is more sensitive to low-quality video artifacts than high-resolution video with low-quality encoding.
This means that even low-resolution videos can appear clear and sharp if encoded with high-quality settings.

The International Telecommunication Union (ITU) recommends a minimum video bitrate of 1280 kbps for SD resolution and 2000 kbps for HD resolution.

Online video converters often have specific settings and algorithms for specific video formats, such as MP4, AVI, or MOV.
Understanding the video's native format and compression settings is crucial for effective upscaling.

The video quality assessment (VQA) algorithm is a widely used method for evaluating video quality.
It calculates metrics like peak signal-to-noise ratio (PSNR), structural similarity index (SSIM), and mean opinion score (MOS) to assess video quality.

The quality of a video converter is often determined by its ability to preserve the original video's quality, rather than simply upscaling the resolution.

The decoding process can affect video quality, especially if the decoder is not optimized for the specific video codec or resolution.

Video transcoding can introduce artifacts, such as loss of quality, loss of frames, or compression artifacts, if not done correctly.
