cannot export a custom aspect ratio video

Copy-Hao commented 7 months ago

Description of bug / unexpected behavior

when i use self.camera.reset_pixel_shape(1600, 900) change the aspect ratio, the export video is incorrect display but the image is correct display
when i set pixel_height and pixel_width in the manim.cfg config file, it doesn't work.
```
[CLI]
```

pixel_height = 900 pixel_width = 1600


## How to reproduce the issue
<!-- Provide a piece of code illustrating the undesired behavior. -->

from manim import *

class ProofWithoutWords(Scene):

def beginning(self):
    self.camera.background_color = "#ece6e2"
    banner = ManimBanner(dark_theme=False)
    self.play(banner.create())
    self.play(banner.expand())
    self.wait()
    self.play(Unwrite(banner))

def section1(self):
    text1 = Text(
        'Google',
        t2c={'[:1]': '#3174f0', '[1:2]': '#e53125',
             '[2:3]': '#fbb003', '[3:4]': '#3174f0',
             '[4:5]': '#269a43', '[5:]': '#e53125'}, font_size=58).scale(3)
    self.add(text1)
    pass

def construct(self):
    self.camera.reset_pixel_shape(1600, 900)
    # video incorrect display
    self.beginning()
    # image correct display
    # self.section1()


render video command

manim -pqk -v DEBUG --renderer=cairo .\ProofWithoutWords.py ProofWithoutWords


## Additional media files
except the export video aspect ratio is 9:16(height: 900, width: 1600), but the actual export video is 16:9.
and the video content is incorrect, i can't see the manim banner.

I don't know where you have found self.camera.reset_pixel_shape(1600, 900) but the working solution to change the pixel resolution together with the scaling of the scene's coordinate system looks like this:

from manim import *

config.frame_width=16
config.frame_height=9
config.pixel_width=1600
config.pixel_height=900
class ProofWithoutWords(Scene):

    def beginning(self):
        self.camera.background_color = "#ece6e2"
        banner = ManimBanner(dark_theme=False)
        self.play(banner.create())
        self.play(banner.expand())
        self.wait()
        self.play(Unwrite(banner))

    def section1(self):
        text1 = Text(
            'Google',
            t2c={'[:1]': '#3174f0', '[1:2]': '#e53125',
                 '[2:3]': '#fbb003', '[3:4]': '#3174f0',
                 '[4:5]': '#269a43', '[5:]': '#e53125'}, font_size=58).scale(3)
        self.add(text1)
        pass

    def construct(self):
        #self.camera.reset_pixel_shape(1600, 900)
        # video incorrect display
        self.beginning()
        # image correct display
        # self.section1()

Thank you, I found this method in the official documentation Camera class, did not see the documentation configuration section, this is my fault.
