Free Uncompressed Stereoscopic 3D HD Test Videos
The RMIT University (Melbourne, Australia) recently unveiled a new project to try to improve stereoscopic 3D video quality and standards adoption by releasing a library of high definition, uncompressed stereoscopic videos for researchers and interested consumers alike.
RMIT3DV is a library of uncompressed stereoscopic 3D high definition video available for free download under a Creative Commons Attribution-ShareAlike License. As part of a research project funded by the Smart Services CRC, the library is a collaboration between RMIT University and Alex and Jono Films in Melbourne, Australia.
The library contains 31 3D stereoscopic videos shot with a Panasonic AG-3DA1 camera at 25 frames/second and ranging from 17 to 148 seconds. Resolution is 1920x1080 pixels. An Mpeg4 compressed version is available for preview (with red/cyan anglyph glasses) while the original uncompressed videos are separated full color left and right files provided in .mov format.
What is RMIT3DV
RMIT3DV is a library of uncompressed stereoscopic 3D HD video, designed to represent a diverse range of content and visual conditions to enable its use in a variety of (research) applications. Currently composed of 31 sequences, shots were designed taking into consideration: level of 3D effect, aesthetic composition, variations in colour, environment (e.g., natural/urban), motion (e.g., traffic/pedestrian/natural), texture (e.g., water, natural greenery, buildings, people, transport), and light (e.g., day/night, natural/artificial, light reflections/shadows). The sequences were all filmed at various indoor and outdoor locations around RMIT University (City Campus) and the Melbourne CBD region.
The aim of RMIT3DV is to provide an all encompassing 3D database that features a large range of conditions and variables for 3D researchers including various day and night situations, buildings, textures, water, fire and moving elements including vehicles and people.
There are currently few publicly available databases of 3D video content available for research purposes, and even fewer sources of uncompressed 3D video. 3D video content currently available for research is often already compressed into AVCHD format (H.264) and/or typically limited in the number, duration and variety of video sequences. If sequences are compressed, attempts to introduce distortion to study 3D video perception are potentially erroneous. Further, if sequences are too short, say, a 10-ec video clip, it can be difficult to gauge the user experience. The hope being that the more content covering different scenarios that can be used as a benchmark across the different devices, the more objective the manufacturers, research community and reviewers can be.
Equally important is the need for the library licence to allow for everyone to perform their own evaluations and to add new reference material which may test different aspects of 3D quality, such as natural and urban settings, moving objects, low light conditions etc.
The database was natively filmed on a Panasonic AG-3DA1 HD 3D camera using Blackmagic Hyperdeck Shuttles and Intel SATA3 SSDs (formatted as HFS+) to record the uncompressed video content. Sequences are 1920 x 1080 HD resolution, 10-bit 4:2:2 YUV at 25 fps (no audio content - yet!) More technical details about the camera rigging, pre-production, stereography, filming and post-production processes and workflows are available here.
Funded by the Smart Services CRC, RMIT3DV is part of a research collaboration between a team of researchers led by Prof. Ian Burnett (School of Electrical and Computer Engineering, RMIT University) and Alex Joseski and Jonathan Burton (Alex and Jono Films) in Melbourne, Australia.

Researchers are encouraged to contribute 3D content to grow the resource for the 3D video research community, however, all new content must also carry this same license.
Watch and Download for free
Visit RMIT3DV to watch the compressed samples or download the full resolution uncompressed files here. Be careful: uncompressed videos are REALLY HUGE files (I mean aroung 10 Gbytes for a single-eye 100 seconds file). Anaglyph preview files in MP4 are usually under 100 Mb in size.
