- Notes about BuildCD
- ===================
- (c) Copyright 1993-1999 Amiga, Inc. All Rights Reserved
- Confidential.
-
-
- The BuildCD software allows you to cut "gold disc" CD-ROMs using an
- Amiga and a Phillips CDD-521 write-once CD-ROM cutter from data files
- which have been prepared for CD-ROM such as an ISO-9660 image file,
- MPEG tracks, and CD Audio tracks.
-
- BuildCD features:
-
- o Easy-to-use gadtools interface
- o Cuts 0 or 1 Data tracks first, and any number of Audio or MPEG tracks
- in any order
- o Displays CD space and time used for all tracks
- o Loads and saves track sheets for frequestly cut titles
-
-
- Required Hardware
- =================
-
- You will need an Amiga with very fast SCSI, fast SCSI harddisks
- with lots of storage space, a Philips CDD 521 Compact Disk Recorder
- (which can cost up to $5000), plus blank gold disks.
-
-
- The following Amiga configurations haved been tested:
-
- 1. 25MHz A3000
- 2. A4000 [25MHz MC68040, 8Mb FAST RAM] with the A4091 or FastLane
- SCSI-2 host adapters.
-
- We have not tested with an A2000/A2091.
-
- The Philips drive requires a steady uninterrupted 300K/second sustained
- transfer rate. We do not know if this is possible with the any hardware
- other than what we have tested.
-
- Hard Disk Drives
- ================
-
- For harddisk space, you will need approximately 3x the amount of space
- your source data takes up, with 1/3 of that on a partition which can be
- reformatted often and which can hold all of your final data for your CD.
-
- We have successfully cut disks with samples of the following drives:
-
- o Seagate/Imprimis/CDC Wren IV,VI,VII
- o Seagate ST11200
- o Maxtor "Magic" 540, 1240
-
- Reselect
- ========
-
- Important!!! The Philips drive can not deal with other drives that have
- Reselect On. If a drive with Reselect On is on the bus when cutting
- disks, you will get errors and will cut a bad disk. You must be sure
- that all SCSI devices on the bus have Reselect OFF. For harddisks, this
- can generally be accomplished with the ReselectOff script and icon
- (ignore the error output for unit numbers you don't have). For some
- drives and other SCSI devices, you may have to consult the documentation
- which came with the device to see if there is a jumper for reselection.
- The Fish Disk tool "RDBInfo" (Disk 779) may be used to check the reslection
- state of individual SCSI units.
-
-
- Other Required Software/Hardware
- ================================
- You need to create the data for your disk and get it into a standard
- CD-ROM format before you can use BuildCD to place the data on the disk.
-
- Suggested tools for getting your data in CD-ROM formats:
-
- - ISO Image (data track)
- For the Amiga, use the Amiga ISOCD program which AmigaCD licensees
- receive without charge. Only the Amiga ISOCD program can create
- a bootable disk for CDTV or CD32. Only licensees may have and use
- this program. Commodore subsidiaries and other licensees may not
- build title disks for a developer unless the developer or publisher
- has signed an AmigaCD license and amendment for that title.
-
- For other systems (Mac and PC), there are commercial software
- packages available for building ISO image files. These packages
- can not build a bootable Amiga CD32 disk.
-
- - Audio tracks
- Digitize with the Studio-16 sampler, and then use the tool called
- "Conversion" by Jim Hawkins to place the sound sample bytes
- in the correct order for a CD track.
-
- - MPEG tracks
- We have these made by providing our video to a company that converts
- our video to MPEG. See the list of some MPEG services at the end of
- this document. Before cutting the MPEG binary you receive from the
- MPEG service, you may need to align and pad it properly by making
- a copy of the stream with the tool called "Padstream".
-
-
- CCOPY
- =====
-
- CCopy must be used to copy your CD-ready data (ISO image, audio tracks,
- mpeg tracks) to a clean FastFileSystem partition (we'll call this the
- "build" partition). You then use BuildCD to cut the CD from the data
- on your build partition.
-
- CCopy is a special version of COPY which attempts to place files
- in a manner optimal for sustained reads when transferring to the Philips
- drive. For CCopy to work properly, it must be used to copy data to an
- Amiga FastFileSystem partition which is either freshly formatted,
- OR has never had files deleted from it. (i.e. you can CCopy multiple
- ISO images, audio tracks, MPEG tracks, etc. to a fresh FFS partition
- as long as you don't delete any files from the partition. Deleting files
- would leave a fragmented disk structure and subsequent CCopy'ed
- files would not be laid down contiguously, possibly making it
- impossible to sustain the transfer rate needed to cut a CD).
-
- If possible, use the V40 Amiga filesystem on this partition and use
- V40 HDToolbox to set the block size for the partition to 2048 instead
- of 512. Do this before formatting the partition. Note - to make sure
- the partition is actually using the 2048 blocksize, use the CLI "Info"
- command after formatting and multiply the number of free blocks shown
- by 2048 and make sure the result is close to the size of the partition
- in bytes. Use of 2048-size blocks will allow BuildCD to read the data
- more quickly from your drive when cutting the CD.
-
- MPEG
- ====
-
- To include a properly encoded and interleaved SIF format MPEG track on a
- CD32 disc...
-
- 1 - Be sure that the MPEG file is properly encoded and interleaved to comply
- with the VideoCD standard. Things to check for...
-
- a - Encoded at the proper VideoCD bit-rates for audio and video.
-
- b - Audio and Video properly interleaved for VideoCD
-
- c - Ready to be written as Mode 2 Form 2 data (properly padded for
- Mode 2 Form 2 sector size.)
-
- d - Two seconds of blank sectors at head of data. (only strictly
- necessary for files that will be played by the ROM player
- interface.)
-
- If either "c" or "d" above are either not true or unsure, run the
- "padstream" program on the MPEG data file.
-
- Command format:
- PadStream Source/A,Dest/A,VideoCD/S
- Where source is the name of the file in question, Dest is the
- file that will be written, and VideoCD is a command line switch
- that should be used if the file will be part of a VideoCD
- compliant disc that is intended to be played by the ROM VideoCD
- player program.
-
- 2 - Use ISOCD to build your data file as normal.
-
- 3 - Use BuildCD 1.31 or greater to cut track 1 as data (with your ISOCD
- generated ISO image as the data file), and tracks 2-99 as either
- audio and/or MPEG tracks. Be sure to specify MPEG for MPEG tracks
- and Audio for Audio tracks.
-
-
- MPEG ENCODING
- =============
- o What is the cost for MPEG encoding ?
-
- Costs vary from between $60/min (Laser Pacific, if you tell them you're
- a CD-I developer) and $170/min (Philips if you tell them you're a CD32
- developer.)
-
- o Are their any Micro based MPEG encoding solutions?
-
- None yet that have the quality of a professional encoding job. There
- is a software based solution from a company called Helfrich in Germany.
- It works using their Piccollo graphics card. The software does a pretty
- good job, but you obviously have to be willing to let it sit a long time
- with each frame if you want decent quality.
-
- We've heard that there are some PC solutions in the works, but haven't
- actually seen anything available yet.
