OpenPrismaMotion
An open source software to visualize pixels movement along time from a video
CLI
The command line interface allow you to generate an Optical Flow video from a source video.
How to use it
-
Install the executable version corresponding to your operating system (Windows is the only one avaible yet)
-
Move the executable in a folder containing at least one video you want to use as a source.
-
Open the folder in wich you placed the executable and your video.
You can directly start by double-clicking it and then choosing your video.
You can also open a terminal (e.g. cmd or a PowerShell) to pass some arguments.
Arguments
| Argument | Following value | Expected type | Note |
|---|---|---|---|
-i | input video | Absolute/Relative path | |
-o | output video | Absolute/Relative path | If an already existing file is given it'll be overwritten |
-h --help | Display an help message with the existing arguments | ||
--drawOver | Use the source in the output, draw the arrows over the source frames, otherwise arrows will be drawed on an empty frame | ||
--frame | number of frame | Unsigned int | Specify how many frame should be generated |
The
--drawOverargument won't affect the source video which is never modified
The
--frameargument is usefull to avoid generating an entire video wich can take a long time. The process still need multiple optimization
After generation
Once the output is ready it'll be directly viewable using a compatible video viewer. You'll be notified by a prompt asking if you wan't to open it directly
