- Before spending any money on decks, you'd better check-out the following.

- DIGITAL EDITMASTER
- Non-linear Editing System
-
-
- "The Digital EditMaster system and a Commodore Amiga is a complete,
- professional quality, digital video editing suite for under $5000."
-
- * Full-motion JPEG Technology
-
- * Real-time 30fps Video Capture
-
- * Real-time Video Display & Recording
-
- * Frame-by-frame Recording
-
- * Full Screen Non-linear Editing
-
- * SMPTE Time Code Read & Write
-
-
- The Digital EditMaster ($2495 list) system from Digital Micronics, Inc.
- (DMI) allows you to edit and produce professional quality video productions
- on Commodore Amiga computers. It lets you capture in real time full-screen
- NTSC, PAL and SVHS video to a standard Amiga hard drive at 30 fps (25 in
- PAL), edit your production and then output the final results in real-time
- to a standard video tape recorder.
-
-
-
- NON-LINEAR EDITING SOFTWARE -- Stored video segments can be edited,
- modified and played back to tape. DMI's Digital EditMaster software allows
- instant access to any number of video segments strored on the hard drive,
- giving complete creative freedom and flexibility to the editor.
-
-
- THE DMI BUS -- Supports the DMI 32-bit pixel bus which allows direct 32-bit
- connectivity with DMI's Vivid 24 (tm) graphics co-processor. [100,000
- Shaded Polygons Per Second, 160 MFLOPS (an SGI Indigo does 4.2 MFLOPS for
- comparison), 24-bit Color Gfx, 8-bit Alpha Channel, 2048 X 2048 interlaced
- resolution or 1280 X 1024 non-interlaced resolution, real-time simulations]
-
-
- AUDIO -- The Digital EditMaster and SunRize Industry sound boards are fully
- integrated using SMPTE time code for simultaneous digitizing and editing of
- both audio and video tracks.
-
-
- SPECIAL EFFECTS -- Version 1.0 [boy, this is bran new] includes basic cut
- and paste capabilities and the abiliy to playback video and frame-by-frame
- animation in real-time. The next version includes A/B roll, simple wipes,
- fades, etc. As the software matures, more and more features will be added
- so you defintly want to register your board. Software upgrades will be
- free during the initial stages of development. [This board, being
- inexpesive, will probably also attract the support of current Amiga
- software companies as well as other third parties so all kinds of software
- and support will probably soon be available.]
-
-
- COMPARISONS TO OTHER SYSTEMS (Avid, Emc2, DigitalFilm, etc.) -- First, the
- Digital EditMaster system takes advantage of the incredible speed of the
- Amiga bus (33 MB per second) which in not available on other desktop
- platforms. This allows video to be digitized *into* the system using a
- very low compression ratio. This is a distinct advantage over digital
- editing systems on other platforms. Second, the Digital EditMaster system
- uses the full motion JPEG chipset from LSI Logic. The LSI chipset operates
- internally at a 4:2:2 digital resolution of 720 X 486. Other products
- which use C-Cubed JPEG chips, generally digitize the video signal at much
- lower pixel resolution, as low as 320 X 200. The high resolution and low
- compression ratio of this system make it possible for the Digital
- EditMaster to output edited video at Betacam quality.
-
- VIDEO QUALITY -- There have been many articles written describing how JPEG
- compression affects video quality. One such article states that between
- 5:1 and 10:1 compares to Betacam, 15:1 is considered "visually lossless"
- and compared to 3/4 inch, and 25:1 compares to VHS. [Compression ratios
- are selectable from 15:1 to 70:1]
