FR-AI / ANALYSISWhy it is worth attention
It provides a simple, accessible way to visualize motion in videos through optical flow arrows, with no need for complex setup, and is open for community contribution.
Who it is for
- Developers building motion analysis pipelines
- Researchers studying optical flow visualization
- Video editors wanting to overlay motion vectors
- Hobbyists experimenting with computer vision
Use cases
- Analyzing motion patterns in surveillance or sports footage
- Creating educational animations of optical flow
- Debugging or validating optical flow algorithms
- Generating overlay graphics for video analysis
Strengths
- Straightforward CLI with clear arguments
- Open source, enabling customization and auditing
- Direct output viewable with any compatible player
- Supports selective frame generation to save time
Considerations
- Only Windows executable is currently available
- Performance is noted as needing optimization
- No graphical user interface for non-CLI users
- Limited documentation beyond basic usage
README quick start
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
