Is Converting a Video from 720p to 1080p Worth It? Understanding the Limits of Up-Scaling
When considering converting a video from 720p to 1080p, many wonder if this adjustment will truly enhance the video quality. The answer is not clear-cut due to the technical nature of video resolution and up-scaling. Let's break down the concepts involved and understand why converting a 720p video to 1080p might not always yield the expected improvements in visual quality.
Understanding Resolution
Before delving into up-scaling, it's essential to understand the basics of video resolution. 720p has a resolution of 128720 pixels, while 1080p offers 1921080 pixels. This increased resolution in 1080p allows for more detailed visuals, provided the original content supports such quality.
What is Upscaling?
When you convert a 720p video to 1080p, you are essentially up-scaling the video. This process involves increasing the pixel dimensions, but it does not add new detail. The software used in up-scaling algorithms can only guess at the missing details and fill in with interpolated data. In essence, you are not increasing the amount of actual information in the video; you are only expanding the existing
Perceived Quality and Display Preferences
The perceived quality of the upscaled video can vary depending on several factors, including the playback device and the distance from the screen. On smaller screens, the difference between 720p and 1080p might be minimal. However, on larger displays, the lack of true detail from the original 720p source becomes more noticeable. The TV or projector performing the up-scaling will also play a significant role in the final visual outcome.
Conclusion
In summary, while a 1080p video is technically higher resolution than a 720p video, simply converting a 720p video to 1080p does not necessarily make it better. Upscaling cannot add information that wasn't in the original video. The video won’t become any clearer or sharper, but it might require more storage or bandwidth/processing power to play. The best approach is to shoot in the highest possible resolution that you have. If you have 4K, do it in 4K. You can always downscale later, but up-scaling never works out for better. It is better to let the TV or projector do the scaling for you.
