Playback Tools for VFX
You need a player that can scrub image sequences (EXR, DPX) and movie proxies at speed, with color management you trust. Nuke’s viewer is fine while you work. For dailies, version flips, and “does this actually play,” people reach for dedicated playback.

Playback Tools for VFX
You need a player that can scrub image sequences (EXR, DPX) and movie proxies at speed, with color management you trust. Nuke’s viewer is fine while you work. For dailies, version flips, and “does this actually play,” people reach for dedicated playback.
Below are the tools you will actually see in VFX and post.
RV / Open RV
The industry default review player for many studios. Fast sequence playback, A/B compare, annotations, playlists, OCIO-friendly viewing. Originally Tweak Software; now Autodesk. Won a Sci-Tech award for a reason.
Open RV is the open-source build (Academy Software Foundation). Good enough for most artist review. Commercial RV still has a wider format/codec matrix and support.
Prebuilt Open RV
Building from source is heavy. Prebuilt Linux / macOS ARM64 / Windows packages (CY2025 Release):
Platform | Artifact |
|---|---|
Linux x86_64 | |
macOS ARM64 | |
Windows x86_64 | |
macOS won’t open the app
Gatekeeper often blocks downloaded builds:
(Change the path if your build is not in /Applications.)
xSTUDIO
DNEG’s high-performance playback and review app, open-sourced under the ASWF (github.com/AcademySoftwareFoundation/xstudio). Built for facility review — workstations through screening rooms — with inspection tools and pipeline APIs (C++ / Python).
Main open alternative to RV when you want something designed and used at large VFX scale.

DJV
Free, open-source media player aimed at VFX image sequences (DJV site, GitHub). Plays high-res, high-bit-depth sequences and movies in real time: A/B compare, OCIO, timeline support (OTIO), multi-track audio. Lightweight install, no studio license.
Good default when you need “open EXRs and flip” without building Open RV or wiring xSTUDIO.
VLC
VLC is the universal free movie player. Everyone has it. Great for H.264 / ProRes / QuickTime proxies, client deliveries, and “does this file open on a random laptop?”
It is not a VFX sequence player: weak or no EXR/DPX flipbook workflow, no serious OCIO review stack, not built for frame-accurate dailies the way RV / DJV / xSTUDIO are. Use it for movies and encoded previews — not as your only EXR review tool.
Other players you will hear about
Tool | Role |
|---|---|
mrv2 (successor to mrViewer) | Free flipbook / sequence player; common open alternative alongside DJV |
Nuke / Nuke Studio / Hiero | In-comp and timeline review; editorial + VFX in one Autodesk timeline stack |
What to use when
Need | Use |
|---|---|
Studio-standard sequence review | RV / Open RV |
Open facility-grade player | xSTUDIO |
Free EXR flipbook, simple install | DJV (or mrv2) |
Encoded movies / “just open the file” | VLC |
Rule of thumb: review EXRs in a color-managed sequence player (RV, xSTUDIO, DJV). Use VLC for proxies and deliveries.
