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 is built on top of the RVX Core, a new GPU-accelerated image processing architecture that combines fast IO, resolution-independent image handling, GPU-based floating point image pipeline, linear light workflow, and advanced color management. The RVX Core also adds a major new dimension to RV's customizability--user programmable GPU image processing operations (GLSL shaders) that can be integrated into custom RV workflows.

New versions of RV-SDI (with HD SDI output) and RVIO (command-line transcoding and RV Session processing) are also based on the RVX Core.

  • RVX Core: New GPU-accelerated image processing architecture
  • Color Pipeline Toolkit: Library of GPU accelerated color transforms that can be chained into custom color pipelines
  • Quicktime support cross platform including for Windows 64 bit RV and RV-SDI
  • OpenColorIO
  • Editorial transitions: "Cross-fade" and "Wipe" transition nodes can be added to Session files
  • Per-device display preferences and display auto-detect
  • New toolbars 
  • Dithering to 8 and 10 bits: display high bit-depth imagery without banding
  • User-programmable image processing using GLSL shaders (requires RVX Development license to author shaders)
  • Lens warping/unwarping
  • OpenExr 2.0 multi-part file support


RV-SDI Key Features:

  • 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
  • Realtime 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.

Tweak RV licenses are delivered electronically via email.

Node-lock and Network floating licenses are cross-platform and can be combined into one key if needed.

Your primary Ethernet ID MAC address is used to lock the license and must be provided before licenses can be delivered.

Network floating licenses

Network floating licenses require Tweak Software's TLM Server to be installed, configured and running in order to distribute licenses to network clients.

TLM Server can run on either Windows, OSX and Linux and distributes licenses to either platforms simultaneously.


Although Tweak tests and releases builds of tlm_server for all three platforms, the Linux and OS X versions are more mature and most fully tested. If possible we recommend using a Linux or OS X box as a license server, even when serving licenses to Windows clients.
