# vidmaker
A python library which simplifies creating and exporting videos.
## Purpose
vidmaker was created because I wanted to record some of my pygame projects, and I found this to be the most convenient way.
## How to use
NOTE: vidmaker uses temporary disk space to store frames. This prevents over usage of memory, but slows it down
Since this is a python library, install it by `pip install vidmaker`
Currently vidmaker only has one class, `Video`, making it extremely simple to use.
First, you have to initialize your video with the path you want it to render at the fps and the resolution. Always include the ".mp4" ending to the path, vidmaker DOES NOT do it for you.
```py
import vidmaker
video = vidmaker.Video(path="vidmaker.mp4", fps=60, resolution=(300, 300))
```
Then you have to update the video every frame with the image you want it to add to your video.
```py
import pygame
import vidmaker
FPS = 60
WINDOW = pygame.display.set_mode((300, 300))
# If fps and resolution are auto then late_export has to be True
video = vidmaker.Video("vidmaker.mp4", late_export=True)
pygame.display.set_caption("vidmaker test")
def main(window):
pygame.init()
clock = pygame.time.Clock()
while True:
clock.tick(FPS)
window.fill((255, 0, 0))
events = pygame.event.get()
keys = pygame.key.get_pressed()
ctrl_pressed = keys[pygame.K_LCTRL] or keys[pygame.K_RCTRL]
for event in events:
if event.type == pygame.QUIT:
pygame.quit()
return
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_q and ctrl_pressed:
pygame.quit()
return
# set inverted=True if your colors are inverted
video.update(pygame.surfarray.pixels3d(window).swapaxes(0, 1), inverted=False) # THIS LINE
pygame.display.update()
main(WINDOW)
```
Once your program finishes, you just have to export your video
```py
video.export(verbose=True)
```
If you have a long video, you may consider compressing it to a smaller file size. vidmaker offers custom compression although it requires ffmpeg and is not super accurate, although very useful. If your desired compression settings don't turn out as intended, you can just run compress again with the rest of the code commented out.
```py
video.compress(target_size=1024, new_file=True) # target_size is in KB
```
```py
"""
Old code of unsuccessful compression
"""
video.compress(target_size=2048, new_file=True) # keep testing different compression sizes until you find a good one
```
That's it! You should find your video fully rendered at the given path, but the longer the video, the longer `video.export()` and `video.compress()` take. I tested around 100fps during exporting on my computer and it should be even faster without verbose; compression is also much faster than export. The speed does heavily depend of what you are exporting and your computer.
## Contributing
Contributing is always appreciated! I would love it if anyone was to make a pull request to add another feature or create an issue post. Possible features could be things like an option to use memory instead of disk space, the option to render videos in different formats (only mp4 right now), and many more. If there is enough demand I might add some myself as well. Thanks for the support!
