At an optimum point, you get possibly the best looking picture, i.e., even if you add bits and bytes to it, it may not give the impression of being any better. The PQ increases as you go on increasing the file size. A tradeoff exists between the PQ and the data size. Lower quality pictures might be blurry, or have blocky video artifacts.

The primary challenge is that one needs to maintain the transparency, i.e., how close the picture quality (PQ) of the encoded frame is to that of the original frame, at the smallest possible size. In the world of video encoding/transcoding, there are a plethora of applications, including the free ones. If your operating system is Windows 8 or above, you won’t need to install anything (.NET 4 pre-installed). If you don’t have it installed in Windows 7, VidCoder will prompt you to download and install it. No option to keep the original resolution.No option to keep the original untouched audio.Small encoded preview clips can be created.‘Same as source’ option for the audio sample rate, ‘Auto’ option for the bitrate.‘Framerate (FPS)’ ‘Same as source’ selection for video.Target size, bitrate or quality choice for video.Detelecine, decomb, deinterlace, denoise, deblock, rotation, reflect filters.‘Keep Aspect Ratio’, ‘Cropping’ options for picture.Completely integrated encoding pipeline: no large intermediate temporary files.AAC, HE-AAC, AC3, MP3 audio codec options and ‘Passthrough if possible’.Vidcoder helps convert videos ( aka re-encoding or transcoding) for your iPod, iPhone, iPad, PSP, Android/Windows phone/tablet or even laptop, and implement subtitles, chapter break-ups, and the other customizations. VidCoder also adds pared-down menus and options. The UI of VidCoder seems to be a little more pleasing to the eye than that of HandBrake. Why VidCoder when Handbrake itself helps convert videos for your devices, and does the other customizations? Well, to some of us, the user interface (UI) of HandBrake is a bit daunting to the novices, at least on Windows platform. VidCoder uses HandBrake as its encoding engine. HandBrake is an extremely popular open source cross-platform (Windows, Mac and Linux) freeware for converting ( aka transcoding) videos from virtually any format to the most modern, widely supported, user-friendly formats.
