One option that is available within REDCINE is to convert the source media into sequential

DPX files. The DPX files can be assigned a variety of frame sizes, including RED's own RED ONE

2K aspect ratio, which will result in 2048x1152 sized images. Note that a large number of

applications may expect to work with DPX files at a more standard frame size, such as

2048x1556.

This frame size can also be produced in REDCINE and the image can be scaled to fit within this

frame size via X and Y scale settings in the application. Also of note, REDCINE produced DPX

files, unlike either the proxies or the files created via the Log and Transfer method, can be

assigned 4:4:4 RGB values, not just Y,Pb,Pr 4:2:2 values. After producing the sequential DPX

files via REDCINE, the files can be wrapped into QuickTime reference movies or self-contained

QuickTime movies using the AJA DPXToQT Translator application.

This workflow is more complex than the other two outlined, but yields very high quality

results. When interfacing with other applications, such as high-end color correction or visual

effects applications, DPX files might be the desired file type. Note that the bandwidth

requirements for the playback of sequential DPX files are much higher than the REDCODE

proxy files or the Apple ProRes 422 (HQ) media. Appropriate computer and storage

configurations need to be in place for realtime playback of 2K media.

Double Speed

Transfer for KONA

3G and Sony

HDCAM SR

When used with properly equipped Sony HDCAM SR VTRs (such as the Sony SRW-5800), the

KONA 3G can be configured to ingest material at double normal speed or “DBL” speed. There

are some specific settings and software that need to be used for this. VTR Xchange v4.1 is

required along with KONA 3G driver version 7.5 or later.

To properly ingest audio at double transfer speed, select the “Enable DBL Audio Capture”

checkbox in the Setup tab of the AJA Control Panel application.
