Video resolution determines the amount of detail in your video or how realistic and clear the video appears. In general, the higher the resolution your video has, the clearer it looks. But if the wrong resolution is used the video will look stretched and has a black bar. This works the same as the video aspect ratio. This recommended Windows video editor provides three options to change the video resolution. By the way, 1080P, 4K, and 8K videos all are supported.

Besides video resolution, frame rate, and bitrate also matter in video quality. Frame rate measures how quickly a number of frames displays within a second, indicating how smooth the video looks. And higher bitrate results in a larger file and a better look for the video.

In Parameter settings, you can customize them by choosing from the given options or inputting a specific value.

What’s more, you can switch from VBR (Variable Bitrate) to CBR (Constant Bitrate), and vice versa based on your actual needs.

Poor audio quality can also lower the video quality. Both contribute to the overall perceived audiovisual quality. Sometimes, when we are talking about how to fix low quality videos, there are chances we are exploring the way to enhance the audio quality.

Audio quality mainly depends upon four aspects: sample rate, bitrate, format and encoded method. Of course, the volume level matters as well.

With HD Video Converter Factory, you can adjust the audio volume, add background music, transcode your audio, switch stereo to mono and vice versa, and modify bitrate (i.e. Convert MP3 128kbps to 320kbps) and sample rate. Besides, increase your audio volume to 200%.

Incompatible format and missing codecs also contribute to a low-quality video. The video may get extremely pixelated, jerky, shaky, or out-of-sync during the playback. Even worse. The player may fail to open the video and one error message pops up, such as “Windows Media Player encountered a problem while playing the file” or “To play this video, you need a new codec”.
