Theoretically, the quality will be degraded after downscaling from 4K to p. However, you won't notice any quality loss when you play the compressed file on p TV or mobile devices. This is also a useful way to resize GoPro 4K video. After loading target footage, simply click "Option" button and then you'll get access to the panel where you can adjust bit rate, frame rate, GOP and other parameters. Bit rate is an important factor that affects video quality and file size. In theory, the higher the bit rate, the better the video quality and the larger the file size.

However, when the bit rate reaches a critical point, our eyes will no longer notice enhancement of quality, but only increase of file size. Therefore, we can choose a relatively low bit rate to reduce the file size of GoPro 4K video.

For example, assume that you want to upload a GoPro 4K 30fps video to YouTube, you can set the bit rate to kbps. Frame rate can also impact file size and fluidity of a video. You're suggested to choose a high frame rate when you need to record sports videos. However, it is not necessary to set too high to record a video that isn't full of action scenes. The size of 1 I-frame is far larger than that of B- and P-frames.

So, when we increase the value of GOP, the number of I-frames in a video will be decreased, thus reducing the file size. When you transcode your GoPro 4K video with "Auto Copy" selected and "Force Copy" disabled, it will transcode the audio only and deliver a smaller file.
