bpsrender 0.1.3

Blender Power Sequencer Renderer

This is a standalone python package as well as a module which is used under the hood in the Blender Power Sequencer add-on to speed up rendering VSE projects by spawning Blender processes in background in parallel.

Install

It can be installed as a standalone command line utility via PiPy: pip install [--user] bpsrender. Note that you have to have $HOME/.local/bin included in your $PATH environment variable (on unix) if you’re going to install the utility locally (using --user when executing pip).

Usage

After installing the script, get help by writing bpsrender -h:

usage: bpsrender [-h] [-w WORKERS] [-v] [--dry-run] [-m] [-c] [-d] [-j]
                 blendfile

Multi-process Blender VSE rendering - will attempt to create a folder called
`render` inside of the folder containing `blendfile`. Insider `render` another
folder called `parts` will be created for storing temporary files. These files
will be joined together as the last step to produce the final render which
will be stored inside `render` and it will have the same name as `blendfile`

positional arguments:
  blendfile             Blender project file to render.

optional arguments:
  -h, --help            show this help message and exit
  -w WORKERS, --workers WORKERS
                        Number of workers in the pool (for video rendering).
  -v, --verbose         Increase verbosity level (eg. -vvv).
  --dry-run             Run the script without actual rendering or creating
                        files and folders. For DEBUGGING purposes
  -m, --mixdown-only    ONLY render the audio MIXDOWN
  -c, --concatenate-only
                        ONLY CONCATENATE the (already) available video chunks
  -d, --video-only      ONLY render the VIDEO (implies --concatenate-only).
  -j, --join-only       ONLY JOIN the mixdown with the video. This will
                        produce the final render
