How to improve the quality of downloaded videos from Jewtube and co.

Why shouldn’t I share a few of those little things I learned on the road. A lot of people nowadays seem to download video from sites like google.video and co and sometimes also upload them somewhere else, a process which done directly does not work without a further reduction of the video quality, which means that the second time uploaded video will look visibly inferior to the downloaded version because the already heavily compressed version will undergo the same process of compression a second time when being uploaded to one of those various video hosting sites around. But there is a easy and fast way to solve this problem!

All needed for it is the open source video converter “Media Coder” which may be download here.

Media Coder is probably one of the best video converting tools out there, media coder works with pretty much with all known formats and offers a lot of helpful options. At first all those options may be a little confusing but this impression will cease rather fast. The main problems with videos download from most hosting sites is high compression leading to low quality and possible artifacts, and low resolution, both which can be taken care of easily with media coder. The standard resolution of most video hosting sites is 320×240, I found that the best value to increase the resolution to while keeping a decent quality seems to be 480×272, which can be done in media coder under “picture”

But only increasing the resolution will only further decrease the video quality, another step is required. Again under “picture” at the bottom on the left is a button called “effects”, pressing this button will open another menu which looks like the fallowing (note that this menu will only open in case there is already a video opened with media coder):

In this menu activate “deblocking”, horizontal and vertical like seen in the picture above, and set the “denoiser” option to “high quality 3D”. That was all, now the only thing left is to choose the video and audio codec you prefer and to start the re-encoding process. I personally use XVid/mp3 and avi. as container for the simple reason that those formats are the most widespread and thus have the least problems with compatibility issues while offering good quality and fast encoding.
