An osu! storyboard to video converter. Will be maintained until an alternative exists in lazer. Very much unmaintained, pending rewrite.
This project has been in progress on and off since the middle of September 2020. Actual time spent working so far has probably been about 6 weeks.
I'll expand this readme eventually. Here are some benchmarks on my computer:
CPU: AMD Ryzen 5 2400G @ 3.70 GHz
Render: 1920x1080 @ 30fps
CPU usage: ~90-95%
| Storyboard | time (mm:ss) |
|---|---|
| Alexithymia | 40:00 |
| Double Pendulum | 17:00 |
| world.execute(me) | 11:00 |
| Asymmetry | 5:12 |
| new beginnings | 2:36 |
- handle errors
- fix all edge-cases
- clean up dumb code
- optimise for performance a bit
- rewrite whole thing in opengl or something
Usage: osb2mp4.exe song_folder [options]
options:
-s, --start-time time start time in ms (default: automatic)
-e, --end-time time end time in ms (default: automatic)
-d, --duration time duration in ms (default: automatic)
-o, --output time output video name (default: video.mp4)
-diff, --difficulty filename difficulty file name (default: first found)
-w, --width pixels video width (default: 1920)
-h, --height pixels video height (default: 1080)
-f, --frame-rate fps video frame rate (default: 30)
-v, --volume volume overall volume from 0 to 100 (default: 100)
-mv, --music-volume volume music volume from 0 to 100 (default: 100)
-ev, --effect-volume volume effect volume from 0 to 100, i.e. samples (default:
100)
-dim, --background-dim dim background dim value from 0 to 100 (default: 0)
-ar, --respect-aspect-ratio change to 4:3 aspect ratio if WidescreenStoryboard
is disabled in the difficulty file
-fail, --show-fail-layer show the fail layer instead of the pass layer
-keep, --keep-temp-files don't delete temporary files (temp.mp3 & temp.avi)
-z, --zoom factor zoom factor to use when rendering, useful for checking
out-of-bounds sprites (default: 1)
On Windows, you can compile with clang (you can get it by installing LLVM) by running the included make.ps1 script. Be sure to fill in the templated variables at the top of the file.
When running, make sure to have opencv_videoio_ffmpeg451_64.dll and opencv_world451.dll in the same folder as osb2mp4.exe.
