Upload in 1080p High Quality - YouTube

How to Upload Better Quality Videos at YouTube

By Rulens Satin

You can now upload videos with high quality images at YouTube because their technology is now 1080p enabled. Just what is 1080p? The word stands for (p)progressive scanning of 1080 rows in a display. 1080p rendering is used for High Definition Television broadcasting and has been adopted for computer videos. There are two ways of rendering electronic images on a display.

1.Interlaced scanning is the technique which involves rendering the odd and even lines on a display as two separate fields. For a display with 50 horizontal lines a scan interlacing the 25 odd and 25 even lines may be performed every 1/25 of a second giving a refresh rate of 25 frames per second.

2.Progressive scanning on the other hand scans all the rows of a display in sequence. Owing to the regular sequence of row rendering, the resulting image is smoother than that from an interlaced scan. A variant of 1080p, the 1080p24, has become the norm for producing digital flicks. This technique also converts interlaced sources to 1080p format.

Currently, not much content is available in 1080p format. Of the few that we have, the Blu-Ray Movies and some internet content are representative. Both the Microsoft WMV and the Apple QuickTime file formats are now 1080p enabled. You can also stream 1080p videos using Microsoft Silverlight and IIS.

Now that YouTube will allow buffs to upload videos in 1080p format, the issue of file size needs to be tackled. But they are probably aware of this over at YouTube. In the near future we may hope to be able to upload files larger than 2 GB.
