Ripping. Ripping is distinct from simple file copying, in that the source audio or video often isn't originally formatted for ease of use in a computer file system; ripping such data usually involves reformatting it and optionally compressing it during the extraction process. The source material being ripped need not be digital; ripping can involve digitizing audio and video originally stored on analog formats, such as vinyl records. Ripping software[edit] A CD ripper, CD grabber or CD extractor is a piece of software designed to extract or "rip" raw digital audio (in format commonly called CDDA) from a compact disc to a file or other output. Some all-in-one ripping programs can simplify the entire process by ripping and burning the audio to disc in one step, possibly re-encoding the audio on-the-fly in the process.

For example, audio CDs contain 16-bit, 44.1 kHz LPCM-encoded audio samples interleaved with secondary data streams and synchronization and error correction info. Legality[edit] Video post-processing. The term post-processing (or postproc for short) is used in the video/film business for quality-improvement image processing (specifically digital image processing) methods used in video playback devices, (such as stand-alone DVD-Video players), and video players software and transcoding software.

It is also commonly used in real-time 3D rendering (such as in video games) to add additional effects. Uses in video production[edit] Video post-processing is the process of changing the perceived quality of a video on playback (done after the decoding process). Image scaling routines such as linear interpolation, bilinear interpolation, or cubic interpolation can for example be performed when increasing the size of images, this involves either subsampling (reducing or shrinking an image) or zooming (enlarging an image).

This helps reduce or hide image artifacts and flaws in the original film material. Uses in 3D rendering[edit] See also[edit] Post-production External links[edit] Bitrate Calculator.

Added Video size, MPEG/Authoring overhead, Audio size, ISO and Total size under advanced mode. Compiled it as one jar file instead of several class files. How To - Choose video type under Type If you are thinking of adding still images, menus, motion menus and extra subtitles and such you must add a few extra MBs to the other ISO files (click on advanced) or lower the calculated bitrate some bits or else it wont fit.

Net - The Definitive DVD Backup Resource. Krzysztof Wojdon - VirtualDub. VirtualDub Filters. This page contains the latest versions of some filters I made for VirtualDub. Put them into the VirtualDub plugins folder and restart VirtualDub to make them available from VirtualDub. Deshaker - video stabilizer Deinterlace - PAL movie Deinterlace - area based Field shift Deinterlace - smooth (go here for Xesdeeni's great AVISynth port of this deinterlacer) General convolution 3D Deinterlace - PAL movie In PAL, two kinds of video exist: 50fps video with half vertical resolution (i.e. interlaced video) and 25fps video with full vertical resolution (i.e. progressive video) Both of these are usually captured as 25fps full resolution video which means that for 50fps video, each frame will consist of two subframes, or "fields".

Settings Swap fields: Sometimes the fields of a frame are in wrong order. Version history: Version 1.1: Added script support.

VirtualDub Plug-ins (Filters) Once you have installed VirtualDub (see my Software page), there are several plug-ins that you must install to complete portions of this guide.

Plug-ins, also called filters, are extensions to VirtualDub that allow it to process video in special fashions. We will use plug-ins to improve the image quality of the video. All of the plug-ins are installed in the same fashion. Here are the plug-ins you may need: 2D Cleaner - This filter can smooth out the background noise in your video. Also, although you will not need them for this guide, you can find more filters at the official VirtualDub Filters page.
