Very long loading times when using a video on a Page

[mate-code]

I use a video on one of my pages (1080p, 2:42, 156 MB) and every time I klick on the "Next" button, I get up to 10 seconds waiting times. I was wondering if anybody else can reproduce this issue or is it doe to running the experiment locally?

Hi Marius, thanks for pointing out the issue! Would you provide us with a minimal example and, ideally, the video file for reproduction?

Minimum example:

import alfred3 as al

exp = al.Experiment()


@exp.member(of_section="main")
class VideoPage(al.WidePage):

    def on_first_show(self):
        gender = self.exp.values.get("gender")
        self.exp.randomizer = al.ListRandomizer(
            ("video_male", 60), ("video_female", 60), name=gender, exp=self.exp
        )
        self.exp.condition = self.exp.randomizer.get_condition()

    def on_exp_access(self):
        condition = self.exp.condition
        video = "male" if condition == "video_male" else "female"
        p = self
        p += al.Video(
            path=f"media/condition-{video}-1080p.mp4",
            allow_fullscreen=True,
            autoplay=True,
            controls=False,
            loop=False,
        )

I'll send you the video privately, as some of the actors do not want the video publicly posted

It is probably best to upload videos to Youtube or a similar service and then embed them with an html element. We give this issue low priority for the time being.
