Python version
Currently, Crispy supports Python 3.8, 3.9, and 3.10.
Configuration
Customize the application by editing the settings.json file. This is where you can adjust algorithm settings and select the game you are processing.
Configuration Example
{
"neural-network": {
"confidence": 0.8
},
"clip": {
"framerate": 8,
"second-before": 3,
"second-after": 3,
"second-between-kills": 5
},
"stretch": false,
"game": "valorant"
}
Available Settings
- neural-network
- confidence: The confidence threshold used by the neural network. Lower values may include more frames but might introduce false positives.
- clip
- framerate: The framerate at which the neural network processes the clips. Higher values include more frames but increase processing time.
- second-before: Number of seconds to include before the highlight.
- second-after: Number of seconds to include after the highlight.
- second-between-kills: Maximum time between kills to be considered part of the same highlight. If the time between two highlights is less than this value, they will be merged.
- stretch: Set to
true if you’re playing on a 4:3 resolution but your clips are recorded in 16:9.
- game: The game you are processing. Options are
"valorant", "overwatch", "csgo2", "the-finals", "league-of-legends".
Recommended Settings
It’s recommended to experiment with the settings to achieve the best results for your videos. Below are some configurations that have worked well:
Valorant
{
"neural-network": {
"confidence": 0.8
},
"clip": {
"framerate": 8,
"second-before": 4,
"second-after": 0.5,
"second-between-kills": 3
},
"stretch": false,
"game": "valorant"
}
Overwatch 2
{
"neural-network": {
"confidence": 0.6
},
"clip": {
"framerate": 8,
"second-before": 4,
"second-after": 3,
"second-between-kills": 5
},
"stretch": false,
"game": "overwatch"
}
CSGO 2
{
"neural-network": {
"confidence": 0.7
},
"clip": {
"framerate": 8,
"second-before": 4,
"second-after": 1,
"second-between-kills": 3
},
"stretch": false,
"game": "csgo2"
}
The Finals
Since The Finals does not use the neural network, the settings differ slightly. The application uses image recognition and Optical Character Recognition (OCR) to detect kills. Due to the computational demands of OCR, processing can be slow.
Recommendation: Use a framerate of 4 to balance speed and accuracy. Increasing the framerate may improve results but will significantly increase processing time (a maximum of 8 is suggested).
{
"clip": {
"framerate": 4,
"second-before": 6,
"second-after": 0,
"second-between-kills": 6
},
"stretch": false,
"game": "the-finals"
}
League of Legends
For League of Legends, image recognition is used to detect kills. A lower framerate is sufficient because kill indicators remain on the screen for an extended period.
{
"clip": {
"framerate": 4,
"second-before": 8,
"second-after": 0,
"second-between-kills": 10
},
"stretch": false,
"game": "league-of-legends"
}
Running the Application
After configuration, run the application using the appropriate script:
- For Windows:
run.bat
- For Linux:
run.sh
Frontend Overview
The frontend is a web application that allows you to interact with the Crispy algorithm and customize your video montages. It consists of five main sections:
- Clips
- Segments
- Music
- Effects
- Result
Clips
In the Clips section, you can:
- View and manage your video clips: See a list of your uploaded videos.
- Rearrange clips: Drag and drop to reorder your clips.
- Select clips for segmentation: Use the “Show” toggle to select which videos to process.
- Add custom effects: Apply effects to individual clips.
- Generate segments: After making your selections, click on Generate Segments to create highlights.
Segments
In the Segments section, you can:
- View generated segments: See the list of highlights extracted by the algorithm.
- Include or exclude segments: Use the “Hide” toggle to exclude segments from the final montage.
Music
In the Music section, you can:
- Manage your music tracks: View the list of music files added to the
resources folder.
- Select music for the montage: Use the “Hide” toggle to exclude tracks.
- Rearrange music: Drag and drop to set the order of music tracks in your montage.
Effects
In the Effects section, you can:
- Apply global effects: Add effects that will be applied to the entire video.
- Override with clip effects: Note that effects applied to individual clips will override these global effects.
- Available effects:
- Blur
- Horizontal Flip (
hflip)
- Vertical Flip (
vflip)
- Brightness
- Saturation
- Zoom
- Grayscale
Result
In the Result section, you can:
- Preview your montage: See the final assembled video with all clips, music, and effects applied.
Q&A
Q: I get an Axios error when I load the web page.
A: This error likely occurs because the backend is not running. Please ensure that the backend is operational. Look for the following messages in your console:
INFO: Started server process [XXXX]
INFO: Waiting for application startup.
INFO: Adding X highlights, this may take a while.
WARNING: Wait for `Application startup complete.` to use Crispy.
INFO: Application startup complete.
INFO: Uvicorn running on http://127.0.0.1:7821 (Press CTRL+C to quit)
If you don’t see the Application startup complete message, the backend is still initializing or there is an error. Wait until it completes or check for errors. If issues persist, refer to existing issues, or open a new issue if necessary.
Q: How can I change the game ?
A: To change the game setting in Crispy, follow these steps:
- Stop the application.
- Delete the
.data folder and the session folder in the Crispy directory.
- Edit
settings.json to specify the new game under the "game" key.
- Add and remove any necessary files in the resources folder (e.g., new game dataset).
- Restart the application.
These steps will reset the game configuration, and the new game will be applied upon starting Crispy.
Q: Why are some games not using the neural network?
A: The neural network is designed to detect consistent visual cues that signify highlights, such as specific icons or symbols that appear during kills. Some games do not have these consistent indicators. For those games, we use alternative methods like image recognition or Optical Character Recognition (OCR). While these methods can be slower and less accurate, they are the best available options for games without consistent visual cues.
Q: Why are some games not supported?
A: The neural network requires training specific to each game. If a game is not supported, it means the neural network has not been trained for it yet. You can contribute by training the neural network for the game and submitting a pull request. A tutorial is available here.
Q: In CSGO 2, I moved the UI, and the kills are not detected anymore. What can I do?
A: Currently, the neural network is trained to detect kills based on the default UI layout. Custom UI configurations are not supported at this time. Support for custom UIs may be added in future updates.
Q: Why is the algorithm so slow on The Finals?
A: The algorithm is slow because it relies on OCR to detect the kill feed, which is computationally intensive. To improve processing time, use a lower framerate (e.g., 4 frames per second). Increasing the framerate will significantly increase processing time without substantial improvement in results.
