Video quality suddenly decreased

Dear Support Team,

I have been using D-Id to generate videos from text prompts and have been very happy with the quality until today. I noticed a sudden and significant decrease in the output video quality - the videos now look very grainy and pixelated, almost unusable.

I also observed that the file size of the generated clips has dropped b compared to previous outputs.

I have an important demo scheduled for later today, so prompt action on this issue would be greatly appreciated. I am using the API and calling it from a C# client.

Here was the generated video:

My inputs are:

    var requestBody = new
        {
            script = new
            {
                type = "text",
                input = text,
                provider = new
                {
                    type = "microsoft",
                    voice_id = "en-US-JennyNeural",
                    voice_config = new
                    {
                        style = "Cheerful"
                    }
				},
            },
            presenter_id = "amy-jcwCkr1grs",
            driver_id = "uM00QMwJ9x",
            background = new
            {
                color = "#F1F2F6"
            }
        };

Thanks.
