Tips: How Can You Tell if a Video Is Really HD

HD is the next generation of standard definition and has been widely applied in TV, streaming, gaming, recording, and filmmaking.

Officially, an HD video or an HDTV video refers to a video with a resolution of 720P (1280×720), 1080p or 1080i (1920×1080) and at a frame rate between 24FPS and 60FPS. And its scanning mode can be either progressive or interlace.

But sometimes, the video quality largely drops down after being converted to HD and looks terrible. That's because you may ignore the video bitrate. It indicates how much data of the video color and luminance is output per second and directly makes difference in the video quality.

Therefore, HD converters that only gives you resolution options cannot make real HD videos. Thankfully, VideoProc Converter AI has a full set of video settings so that you can tweak the resolution, frame rate, and bitrate all together.
