FrameLector

framelector 48FrameLector is a dual-stream ingest software including transfer quality control for SD-video legacy sources.

FrameLector Main WindowFrameLector provides ingestion combined with lowlevel transfer analysis for unmonitored paralleled ingest of multiple streams in a simple and intuitive user interface for efficient and quality controlled mass digitization of SD-video tapes.

As an easy-to-use ingest tool that combines built-in shot detection and a mathematically lossless open-source recording/mezzanine format in either 8bit or 10bit, FrameLector allows users to capture SD material – along with its required metadata such as VITC and LTC timecode – without compromising quality. Other features include remote control and an infinitely scalable multi-stream parallel solution with complete previewing.

The hardware supports two parallel ingest sources and connects peripherals through SDI. A separate customized NOA hardware (VTRi-1) provides RS422 and RS232 connection, as well as ISR and RF readout via a simple USB connection.

A typical industrial video digitization facility based on NOA FrameLector and the process frameworks jobDB or mediARC operates with 16 SDI channels of parallel input, whereas any number of ingest channels is possible.

Tech Specs
Analog and digital sources - SD material archiving in 4:2:2 (720 x 576, 720 x 608), 8/10 bit Lossless digitization in open-source archive formats (HuffYUV, FFvHuff)

The target production formats (output of multiple files in different is possibly) are selectable within the workflow to be transcoded with NOA MediaButler.

VTRi + Sensorplates

FrameLector VTRiLinked in between replayers and ingest station, the NOA VTRi module is in charge of forwarding remote control signals to the replayers as well as returning ISR events (provided by VTRs) and/or the logged RF trace (grabbed by a special sensor plate) - both indicating transfer errors- back to the recording software FrameLector.

In FrameLector, both transfer quality indicators will be logged to enable the unambiguous assessment of success of the digitization. As ISR events and RF traces are based on actual physical interaction between tape and reading head, this kind of electrical metadata does not produce false positives.

Operating FrameLector

In the context of an industrial digitization facility, FrameLector is designed to operate as much "hands-off" as possible to minimize necessary interaction of ingest operators with the software in order to optimize the entire industrial digitization process.

Automatic start and stop of recording as well as operation via scanning of barcode enables swift handling and minimizes idle times of VTRs.

Technical and electrical metadata (i.e. ISR and RF information, indicating transfer errors) as well as shot detection results are available directly in FrameLector. In the context of an industrial digitization facility this information will be examined by QC operators in a subsequent step of the workflow.

If FrameLector is operated as a single-station ingest system within the Pico framework, the ingest operator will be able to assess the recording directly in FrameLector. Additionally, also segments (or clips) can be marked for later transcoding to produce frame exact output files.
