I have a h264 video that is too big for Twitter, Please write a bash script to convert it to the right format and the highest supported quality,

Here's a simple bash command to convert your h264 video to the recommended format and maximum supported quality for Twitter: ```bash ffmpeg -i input_video.mp4 -c:v libx264 -preset slow -crf 18 -maxrate 512k -bufsize 1024k -vf scale=1280:720 -c:a copy output_video.mp4 ``` This command uses FFmpeg to transcode your input video to H.264 (libx264) codec with a slow preset, constant rate factor (crf) of 18, maximum bitrate of 512k, buffer size of 1024k, and a resolution of 1280x720 pixels. The audio is copied directly from the input file to the output file without any changes. You can adjust the parameters as needed to suit your specific requirements.
