subclip not behaving properly due to decorator

[jcoelho-aurascape]

Due to the convert_to_seconds decorator in subclip, it is ignoring the t_end argument. I am using python 3.11.9

Expected Behavior

Subclip should be 60 seconds long

Actual Behavior

Subclip is full video

Steps to Reproduce the Problem

Try to subclip a video clip and check the duration

from moviepy.editor import VideoFileClip
video_file = "video.mp4"
clip = VideoFileClip(video_file)
print(clip.duration)
1014.52

subclip = clip.subclip(0, 60)
print(subclip.duration)
1014.52

Clip.py

    @convert_to_seconds(['t_start', 't_end'])
    @apply_to_mask
    @apply_to_audio
    def subclip(self, t_start=0, t_end=None):
        ...
        # Add prints
        print("t_start:", t_start)
        print("t_end:", t_end)

decorators.py

def preprocess_args(fun,varnames):
    """ Applies fun to variables in varnames before launching the function """
    
    def wrapper(f, *a, **kw):
        if hasattr(f, "func_code"):
            func_code = f.func_code # Python 2
        else:
            func_code = f.__code__ # Python 3
            
        names = func_code.co_varnames
        new_a = [fun(arg) if (name in varnames) else arg
                 for (arg, name) in zip(a, names)]
        new_kw = {k: fun(v) if k in varnames else v
                 for (k,v) in kw.items()}
        # Add prints
        print("a, names:", {name: arg for (arg, name) in zip(a, names)})
        print("a:", a)
        print("new_a:", new_a)
        print("kw:", kw)
        print("new_kw:", new_kw)
        return f(*new_a, **new_kw)
    return decorator.decorator(wrapper)


def convert_to_seconds(varnames):
    "Converts the specified variables to seconds"
    return preprocess_args(cvsecs, varnames)

Outputs

a, names: {'args': <moviepy.video.io.VideoFileClip.VideoFileClip object at 0x1429a3710>, 'kw': 0}
a: (<moviepy.video.io.VideoFileClip.VideoFileClip object at 0x1429a3710>, 0,60)
new_a: [<moviepy.video.io.VideoFileClip.VideoFileClip object at 0x1429a3710>, 0]
kw: {}
new_kw: {}
t_start:  0
t_end:  None
