Many people ask if they have Nuevoplayer, will their videos will be of same high quality as on demo website.
This is really weird question.
Video cannot be better quality than it already is.

Other weird thing is when some people think that they will automatically have HD video option because Nuevoplayer supports such feature.
1. Already mentioned once - same video file can't be of different quality.
2. HD switcher feature is possible and appears automatically only if you have 2 different video files same content, but different quality, where one is of so called "HD" quality.

To have multiple videos of same content but different quality your system/script must support such type of conversion first, just like AVS script version 2.x has. And of course uploaded video must be of enough high quality so it could be recognized later as "HD" and converted to multiple instances.

Sorenson(H 263) encoded videos (method used by most of video scripts) are not suggested for high quality video streaming. If you set high bitrate and high resolution such encoded video will be very demanding for streaming, killing server CPU usage, usually not acceptable by most of viewers connection speed.

Only H 264 encoded videos ensure high quality and relatively small file size, and are acceptable for streaming spped. Such videos are of "mp4" file format so your video script must support such file type.
Default mplayer/ffmpeg librariries and tools are not enough to encode H 264 videos. Several other tools are required for "mp4" format processing.

X264 conversion is very extensive process, so the server must be really powerful and good quality.
It cannot be SHARED plan. Also cheap VPS server is not enough.
For several scripts we as Nuevolab offer server setup and conversion classes for such high quality conversion, but there is no sense to ask us for such service if you do not have powerful VPS server or good dedicated server.
We also rather do not agree for such installations on servers from some "amateurish" hosting companies, just to avoid future problems not related to what we install.

Other thing the user must remember that having SD/HD feature requires multiple ( minimum) versions of same video. This means much more disk space usage.

Hope this clears some misunderstandings,
Thanks.
