IndawPass & InstaSync explained


Next Page: Film-chunks »

IndawPass & InstaSync deliver location recordists and telecine colorists from the "seven-seconds-before-camera-start" preroll hassle.

Thanks to 'Film-chunks' (see notes on next page) inserted into the BWF EBU files by the IndawPass workstation, the ultra fast InstaSync speeds up both Aatoncode and traditional-slate syncing.

--

It all starts with the IndawPass workstation designed to handle all audio sync situations a transfer facility encounters - including the 23.976/24.002/ 29.97ndf ones. Unattended, IndawPass transfers 4 track Nagra-D, IVS-TC, and DAT tapes onto SCSI drives (e.g. one hour and a half @16bit/48kHz stereo on a JAZ cartridge, one hour @16bit/ 48kHz stereo on a CDrom).

IndawPass never requires the play-back machine to stop, nor does it lose the slightest audio sample on Smpte timecode breaks induced by recorder stops and starts; a unique feature.

IndawPass's innovative 'audio-page' layout offers the most ergonomic tool for operators to enter slate-marks and scene/take numbers during traditional slate-sync prepping; these entries can be keyed on-the-fly during uninterrupted tape to disk copy and trimmed later. All operator's comments are recorded into film-chunks within the audio files (see under), which are read by Keylink InstaSync and "Avid Film Composers".

Then comes in the "InstaSync" option which turns Keylink into the fastest syncing machine around: with a 2/100 sec. seek time it surpasses the 1 to 5 sec. of the best existing audio synchronisers. Since the disk copies of the audio-tapes can be made while the film is being processed, they arrive in time for the negative - be it AatonCoded or slated - to be synced on the telecine itself.

InstaSync is so fast, it totally eliminates the start-of-take sound voids commonly found in one-light non-stop transfers. Even if the location recordist had switched his recorder at camera start only, i.e. with no preroll at all, the sound will appear on the flashed images (or as soon as the colorist keys the scene/take numbers). Post-telecine syncing is eliminated: quicker rushes, and cheaper too.

InstaSync: Four track disk reader- synchroniser, four AES out, 4 to 2 digital mixer with 16bit DA out. Disk controller for SCSI drives e.g. JAZ, CDrom, etc. For those facilities who prefer to insure audio-sync operations after telecine transfer, the IndawPass workstation receives a PostSync option which instantly locks up the sound from the audioTC recorded in the 3LineVitc of the tape (or from the scene/take numbers read on the slate and keyed by the operator).

IndawPass-4: Four track disk recorder, four AES in/out, Smpte LTC & Video-in, four 20bit DA analog outputs. Interchannel phase measurement and inversion. Disk controller for seven SCSI drives e.g. JAZ, CDrom, etc.

* PostSync option: 3LineVitc reader and on-the-fly synchroniser.
* Keyer option: Keycode, Audio-TC, RGB values and 3LineVitc re-insertion during post-sync operations.
