LANDELLE VIDEO SERVICES
LVS a proposé dès 2004 des serveurs de production vidéo multicam MVR, et un workflow entièrement IP basé sur une vision de la production vidéo.
Cette vision a été encouragée par le CNC ( resultats-de-l-appel-a-projets-2006 ) qui m'a permis de développer une partie du workflow en attendant la vente du produit. Le projet MIA (MVR In Action) n'a pas rempli ses objectifs malgré la grande tolérance du CNC sur le planning car LVS n'a pas fait suffisamment de CA (le financement est partiel). Ce projet à néanmoins abouti à une machine vendable, acquise en deux exemplaires par BUF COMPAGNIE pour la réalisation des films d'animation de Luc Besson (ARTHUR).
Le passage à la HD a été confidentiel en ce qui concerne les technologies d'encodage, avec l'absence de produit OEM permettant l'encodage avec un CODEC éditable. En SD il existait de nombreuses cartes d'encodage, mais en HD l'offre n'était pas publique. LVS n'a donc jamais pu fabriquer de machine équivalente en HD bien que l'ensemble du logiciel fût prévu (couche d’abstraction matérielle).
Cette expérience a été solitaire et difficile, mais instructive en proportion.
1) Mon premier client n'a pas été Français mais Grec (SPORTS COMM).
2) Aucune vente n'a été faite par un apporteur d'affaire - personne ou entreprise - malgré la marge de 20% offerte au dealer. Un dealer multi-cartes préfére toujours capitaliser sur l'existant qui génère du revenu que de miser sur un outsider.
3) J'ai aussi mesuré la difficulté de vendre a des entreprises possédées par la finance, où l'acheteur est un salarié avec des consignes parfois indifférentes aux besoins des techniciens. La performance importe peu au groupe financier qui gère sa rente de situation par d'autres procédés.
4) Enfin j'ai aussi compris que le danger ne vient pas des clients mais des fournisseurs. De même que l'apporteur d'affaire le fournisseur est par nature serviteur de vos concurrents, son choix est vite fait. Les clients aussi peuvent obtenir des faveurs en échange de confidences.
5) Certaines entreprises ont une place dans l'écosystème sans créer de valeur visible (copinage, commission, cavalerie, maçonneries, sectes, partis politiques, etc.).

Indexing + Edit-list ... while recording !
programmable interface to log events along with video using current time code.
preview clickable to build a multicam edit list while recording.
background flush to a remote editing workstation for near-to-live workflows.
MVR shoots on Compact Flash
Open standards / future proof :
the same MPEG2 format as DVD :
fully playable in high-end DVD Players (component or SDI, computer)
imported into any non-linear editor (LIQUID, FCP, EDIUS, PREMIERE, etc.)
one single standard hard drive for many hours of shooting with 10 cameras
instant archiving @ lowest price (manage hard drive like tapes, bar codes, database)
digital asset under control for decades, because MPEG2 is the broadcast standard, worldwide.
uses hard drive / flash disks as consumables (unbeatable price & reliability)
Technical specifications of MVR™ :
Frame accurate sync among all channels (with genlock)
4 to 16 video inputs (SDI - composite)
4 to 32 independent audio inputs (analog XLR - jack3,5)

Industrial grade 4U PC rack (400W, 20kg, 60cm depth)
Windows XP PRO
Key Benefits of MVR™ platform :
up to 16 video recorders in a single 4U rack
industrial PC capable of running your NLE (not during record)
Direct editing of video material (no transfer, no conversion)
Ideal for 576p to 720p blow up
Built-in analog inputs (no nood for conversion)
SAN friendly (MPEG2=smallest file format)
Gigabit, Firewire, Usb2 usable as storage for live recording !
Forgettable MBTF (100000h)
Intellectual property :
Near zero fragmentation for 10 streams on the same disk drive (Multicam File System, MFS™).
Frame-accurate iso-record (gang-record) of non-genlocked sources (Computer Clap ™)
AutoFlush ™ is doing background copy with controlled bandwidth to the Editing workstations
AutoFlush ™ is part of MFS™, and offers a multi-seat solution for near-to-live production at no additional cost
Unique features :
A custom Multi-Instance application (MVRI) allows independant 4 channel operation
Compatible with HDV low-cost camcorder via component output (with or without genlock)
No timecode is needed (no VITC nor LTC)
Easy multi-angle (3D) interactive DVD creation

This hardware was designed to produce frame acurate sync among all cameras, allowing effects like in the great movie « The Matrix ». These effects were available in near-to-live conditions thanks to a « ram » workflow and real-time processing of MPEG transport stream. These effects were allowing combinations of slow-motion, stop-motion, fly-motion.
