i am uploading reels via instagram api , the images are getting uploaded fine but for reels an error occurer The video format is not supported. Please check spec for supported aspect_ratio format.

i am using ffmpeg to compile my vedio

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:", audioFilePath);
            console.log("vedio file path:", videosDir);
            console.log("Subtitles file path:", subtitlesFilePath);

            // Get the list of video files
            let videoFiles = fs.readdirSync(videosDir).filter(file => file.match(/^vidd+.mp4$/));

            // Shuffle video files
            videoFiles = module.exports.shuffleArrayVedios(videoFiles);

            // Create a new FFmpeg command
            const command = ffmpeg();

            // Add video inputs
            videoFiles.forEach(video => {
                command.input(path.join(videosDir, video));
            });

            // Add audio input separately
            command.input(audioFilePath);

            // Create the filter_complex command
            const filterComplex = [
                `[0:v][1:v][2:v][3:v][4:v][5:v][6:v][7:v][8:v][9:v][10:v][11:v][12:v]concat=n=${videoFiles.length}:v=1:a=0[outv]`,
