使用Instagram API上传Reels时提示视频格式不支持的问题求助

大家好，我最近碰到个棘手的问题：用Instagram API上传图片完全没问题，但上传Reels的时候一直报错，提示**"The video format is not supported. Please check spec for supported aspect_ratio format."**

我是用FFmpeg来编译视频的，相关的代码片段如下：

compile: () => {
    return new Promise(async (resolve, reject) => {
        try {
            const videosDir = path.join(__dirname, '../public/images'); // Directory containing video files
            const outputVideoPath = path.join(__dirname, '../public/videos', 'output.mov'); // Output video path
            const audioFilePath = path.join(__dirname, '../voiceOver', 'voiceoverCut.wav'); // Path to the audio file
            // const subtitlesFilePath = path.join(__dirname, '../voiceOver', 'subtitles.srt'); // Path to the subtitles file (using .srt format)
            const subtitlesFilePath = 'D\\:/programming/ai/voiceOver/subtitles.srt' // Path to the subtitles file (using .srt format)

            console.log("Audio file path:", ...

有没有朋友能帮忙分析下问题出在哪？会不会是FFmpeg的参数没配置到位，导致视频的比例或者编码格式不符合Instagram Reels的要求？
