Slide 1:

NON-LINEAR EDITING By INTRODUCTION To ABHI ELECTRONICS

Slide 2:

LINEAR EDITING VTR formats for analog recording tapes : Ampex 2” Quad format , BCN , U-matic highband and low band , Betacam SP Digital Tape recording formats : DV, DVCAM , DVCPRO, DIGITAL S, DIGITAL BETACAM, MPEG IMX, UNCOMPRESSED D5, HD FORMATS

Slide 3:

PROBLEMS WITH LINEAR TAPE BASED EDITING Editing is sequential – first shot first. Long hours spent on rewinding of tapes , search of material Potential risk of damage to original footage. Difficult to insert a new shot in an edit Difficult to experiment with Variations Quality loss more in analog; even with digital Limited Compositing, effects, color correction Capability

Slide 4:

What is NLE NLE is video editing in digital format with standard computer based technology Computer technology is harnessed in Random access, computational and manipulation capability, multiple copies, intelligent search, sophisticated project and media management tools, standard interfaces, and powerful display

Slide 5:

ADVANTAGE WITH NLE Flexibility in all editing functions Easy to do changes, undo, copy, duplicate & multiple version Easy operation for cut, dissolve, wipes and other transition effects Multilayering of video is easy Powerful integration of video and graphics. Tools for filtering, color correction, key framing & special 2D/3D effects Equally powerful audio effects and mixing Possible to trim, compress or expand the length of the clip Support for multi format , multi resolution clips Intelligent and powerful 3D video effect can be created and customised Efficient and intelligent storage

System Requirement:

System Requirement Intel Pentium 233 MHz processor (Higher recommended) PCI 2.1 complaint motherboard 128 MB 0r higher RAM 25 MB of available system hard drive space for drivers and dpsrRality software plus additional space for digitized audio files. SCSI (Small Computer System Interface) System driver recommended, with an additional SCSI system drive for audio files. Dedicated wide SCSI AV drive to store digital video files (at least 18GB) CD-ROM drive (SCSI drive recommended), standard keyboard, three button mouse

System Requirement cont….:

System Requirement cont…. Super VGA display (at least 1024 78624 bit true color) monitor and accelerated graphics card ( 1152 864 or greater recommended). Operating System: Windows 2000 Pro or Windows XP. Internet Explorer 5.0 NTSC or PAL video monitor. Separate audio card is recommended for system sound. VTR Speaker

Slide 10:

A single cable brings Component, S-Video, Composite video, balanced and unbalanced analog from the card to and from the breakout box dpsReality Card

Slide 11:

B-Y R-Y Component Analog Video: (Y, R-Y, B-Y) is the highest quality video and can be captured through dpsReality board. S-Video: is lower in quality compared to Component video and works by separating the chrominance ( color) and luminance (brightness) signals. Composite Video: (CCVS) is the lowest quality compared to Component video and S-Video signals and can be captured through dpsReality board. Only one video source should be connected to the breakout box at a time

Slide 12:

To capture synchronized audio with video, you must connect audio out from the VTR or other playback device to the audio inputs. You can also connect audio-only device for soundtrack production, etc. Balanced Audio (XLR connectors): Preferred over long distances since the balanced audio lines are less noisy. Unbalanced Audio (RCA connectors): Over short distances, excellent quality audio recordings can be achieved using the unbalanced audio lines. Aux Audio : Form computer’s sound card-allows you to input system audio through the dpsReality hardware. Audio Inputs

Slide 13:

Time code is simply a series of labels attached to a recording at timed intervals, generally fraction of second. Each label contains a time of recording. Time code is used for editing, in order to be return repeatedly to a selected time, and for synchronization among audio and video recorders and players. Two versions of time codes are available with the dpsReality board. LTC: is placed on one of the linear audio tracks of the video VITC: is recoded within the picture, during the vertical blanking interval. It can be read from a still frame and provides field-rate accuracy. If you an RS-422 cable connected to your computer, you may also acquire timecode through that interface.

Slide 14:

VIDEO OUTPUTS

Slide 15:

Choose what type of video to output based on whether your VTR and other video and audio equipment can receive balance or unbalance audio. Audio out is connected to speakers for playback or to a VTR or other audio recording device during recording.

Slide 16:

VTR BREAKOUT BOX PC Computer with dpsReality hardware RS-422 Control RS-422 Control cable Connect the RS-422 cable from VTR to front of the breakout box. Connect the RS-422 cable from computer to Back of the breakout box

Slide 17:

Connecting the digital I/O card The digital I/O has a digital audio connector. If you choose the serial digital video option, it will also include three SDI BNC connectors. If you have a DV option for your Digital I/O card, the IEEE-1394 interface is connected to the outside of your computer either through a serial port knockout or through an unused PCI slot.

Slide 18:

Connect the 3-BNC adapter cable to the three outputs on the digital I/O card at the back of the computer. The three cable can connect in any order.Attach the other end of this cable to the breakout box. Ensure that the same color cable that is attached to the SDI In on the digital I/O card is attached to the SDI In on the breakout box. The two SDI out connectors feed video /alpha channel Attach the 15-pin connector on one end to the digital I/O card. Attach the other end to the connector marked Digital audio on the breakout box If you have the DV option, attach the IEEE-1394 cable to the connector on the computer, and to the breakout box. Now, hook up a cable from the DV device to IEEE-1394 connector on the front of the breakout box Connect a cable from your SDI VTR to the SDI In connector on the front of your breakout box. Connect one or two output devices to SDI OUT1 and SDI OUT2 connectors

Slide 19:

Connect digital audio devices to your AES/EBU and S/P DIF connectors on the front of your breakout box. There are three digital audio option Balanced AES/EBU (XLR connectors) is the standard digital audio format Unbalanced AES/EBU (RCA connectors) are also available. S/P DIF (RCA connectors) audio is found on consumer-level electronics
