For example, you may that the 4K video is very choppy when viewing on slow or under powered computer or your smartphone and tablets get stutter when handling 60fps video. To fix all those video quality concerned issue, you will need a workable video quality converter to change the video quality to let then match with your devices.
What will influence video quality? Codec, Resolution, Bitrate, Frame Rate, etc or other?
Before searching on the Internet for a Video Quality Converter, there is still another important questions that you should be clear: how to change video quality? To fix this problem, you should know what factors that will influence a video quality. The fact is that the video quality can be determined by various different factors including codec, resolution, bit rate, frame rate, aspect ratio, etc. The following will show how those factors’ influence on video quality with great details.
1. Codec
Different codecs will lead to the differences results among video sizes, but also video quality. Usually we will choose to convert videos to H.265, H.264, Xvid, WMV9 or Real9 when converting videos to MP4, AVI, WMV etc., causing a discrepancy in video quality. Besides, during the converting process, it’s inevitable to get videos compressed, which also matters a lot on video quality. To make it clear, we have a video quality test to convert and compress a 15fps, 120kbps, 150KB video to H.264, DivX, XviD, WMV9, Real9, Quicktime.
2. Resolution
The higher the video resolution is, the higher the quality is. However, the higher the resolution, the larger the file size will be. Obviously, a 4K video will kook clear than 1080p or 720p video. Different devices will have different resolution playback requirements. Generally 640×480 for Apple TV or iOS devices; 720×480 for Android Samsung, HTC; 720×480 or 320×240 for Microsoft WP8, Xbox, Surface, Zune and Sony PS4, PS3, PSP etc. You can compress 4k to 1080p, 1080p to 720p, or 720p to 480p according to your needs.
3. Bit rate
Firstly bitrate in proportion to file size of a video, reflecting the richness of the content. It means if there are two videos in same size, resolution and others, the higher bitrate one will be sharper and in better quality than the lower one. So adjusting bitrate is an effective choice to change video quality.
4. Frame rate.
Frame rate is the frequency at which consecutive images called frames are displayed in an animated display. It influences more about the video’s fluency rather than quality. Therefore, as you change video quality from high to low, you can omit the frame rate adjusting option, since it has little impact on quality.
5. Aspect ratio
It’s more reflected on the video’s display when playing video on Mac, iPhone iPad Android. If you watch a 4:3 video on a 16:9 screen, the video image will be squashed. Given that, if you’re gonna to watch videos on a 16:9 HDTV, you can make use of an aspect ratio converter to convert 4:3 to 16:9 aspect ratio for a better video quality.
