File formats and structures in V-Nova PresenZ

Understanding the different files utilized by V-Nova PresenZ

File formats in V-Nova PresenZ

.przDetect

Detect files are generated in the first section of the two-phase render process in V-Nova PresenZ. They contain information on what is visible from inside the Zone Of View. This is an essential part of the render and limits the information that is rendered in each block. It contains info on geometry but no color data or any aov’s. It can still be inspected inside Houdini with the V-Nova PresenZ nodes. And it is used for the second phase: the render phase.

• 2d equivalent: none, this file is a technical intermediary file

.przRender

This is an uncompressed file format used for the compositing phase of V-Nova PresenZ. It contains all the aov’s and colour values useful in the compositing process. This is a large file that is not suitable for viewing in playback.

• 2d equivalent: “.exr” or ".raw"

.prz = these files are usually only compressed in lossless. They are PresenZ Image generated by the Merge/Prz_Maker from the .przRender file. It’s not a massive compression on the file, but it can be used in the viewer or player to have effective playback.

• 2d equivalent: “.png”

.przShot

A lossy but qualitative compression of a sequence of .prz files. This is much more compact and convenient to carry around. It can be directly played back by the player.

• 2d equivalent: a ".mov" corresponding to one shot of the movie.

.przToc

A file that defines the PresenZ movie, pointing to the different shots, audio, background, and other attributes specific to PresenZ. The TOC stands for Table Of Content. It is usually generated by the Sequencer, the equivalent of a Video Editing software.

• 2d equivalent: ".edl"
