Tweak announces RV SDI and NAB 2011 Plans

RV SDI is finally here. Many of  you have requested the ability to play out from RV directly to your projectors (particularly in stereo) and our new product does just that. We announced yesterday our plan to show RV SDI at NAB in April. It is currently in Beta testing on Linux and Windows.

We will be at NAB in Las Vegas April 11-14 in Booth SL9707. Please stop by to say hello and check out our latest stuff. We will be demonstrating RV SDI, the latest RV/Nuke tools and the latest RV/Shotgun integration.

RV SDI Overview

RV SDI matches the flexibility of RV's dailies sessions with full quality SDI output. RV SDI supports dual stream output for stereo playback, embeds audio in the SDI signal, and takes advantage of RV's flexible tools for review, editing, collaboration, annotation, and comparison of media.


RV SDI Key Features:

  • Stereo playback over Dual Link SDI: using Nvidia SDI hardware
  • High Resolution, high bit depth
  • 24 bit embedded audio
  • Playback: 2K, HDR, Floating Point, Playback from RAM or Disk
  • Review: Organize and annotate media dailies review
  • Collaboration: Connect to other artists, clients or vendors for remote review
  • Editing: Edit sequences with lightweight intuitive tools
  • Comparison: Layout shots or cuts in tiled views, A/B compares with wipes
  • Integration: Script, customize, automate RV to fit into your pipeline or workflow

RV Presentation Mode

RV SDI introduces Presentation Mode. This mode allows users to control RV normally on one monitor while sending video out to another device. The controller view displays the RV GUI and the SDI presentation device sends final output through the SDI channel for display on a projector or monitor (with options to view the timeline and other tools on the SDI view)

RV Sessions for Dailies

 RV's rich session file is a powerful tool for organizing dailies. The session manager makes it easy to combine, compare, edit and annotate media. You can create sessions in advance of dailies with all of the versions, sequences, A/B split screens, layouts or other items to review.

During dailies you can work through your playlist, see shots in context or alone, annotate, edit the timeline, switch versions, and easily create new views on the fly.

Some things you can do with RV sessions include:

  • Layout sources in a 'contact sheet'
  • Compare two or more EDLs (A/B, layout)
  • Create an edited sequence with alternate takes to swap in/out
  • Retime media (pull up/down, change fps, offset)
  • Make and edit sequences, re-order, trim
  • Annotate on top of any view
  • Export WYSYWIG to a snapshot or a movie

The RV session is fully recursive. This means you can recombine anything you make in RV in new ways. For example, You could make a layout of sequences, or a sequence of layouts. Or you could make Folders of alternate takes and then make a sequence of folders.


RV is highly customizable and can be knit very tightly into custom dailies workflows. RV session files are ascii files in an open source format (GTO). Many shops integrate editorial and production databases with RV by writing Python scripts to create custom RV sessions for dailies.


Mix resolutions, frame rates, and color spaces automatically

  • RV is resolution independent, which means you can mix sources of different resolutions and RV automatically fits them to the display window. No manual resizing is required to cut together mixed resolution sources (say SD reference video with Full App EXR renders and 1/2 res animation takes)
  • Realtime pull-down/pull-up to handle any frame rates. RV automatically retimes media to play it back at the output fps (even for fixed rate SDI playback) so you never have to pre-convert media before viewing it in RV. This means you can cut together media of different frame rates into the same timeline, layout, or A/B compare.
  • Advanced Color Management - RV converts media into a common color space so sources with completely different color spaces can be edited together and compared and can use the same display LUTs or other color settings. For example you can cut together Kodak Log DPX frames with sRGB Quicktime video and Linear Exr files and preserve the correct colors.

    Are there any known restrictions to RV Sync'd session if a client uses RV-SDI and we use RV standard?

    Hi Cody,

    No, that should work fine.  It gets tricky when you have different media, but RV and RVSDI should talk to each other no problem.
