🌐 Why .mov Files Don’t Work in Browsers

Apple's .mov format often uses proprietary codecs (like ProRes) that aren’t supported by most web browsers. Even if the file plays fine on your Mac, it may not work in Chrome, Firefox, or Safari on other platforms.

✅ Convert .mov to .mp4 for Web

To make it web-friendly, convert it to .mp4 using H.264 and AAC:

ffmpeg -i input.mov -vcodec libx264 -acodec aac output.mp4

Want even smaller files? Add -crf 23 (lower is better quality, 18–28 is typical):

ffmpeg -i input.mov -vcodec libx264 -acodec aac -crf 23 output.mp4

Now you can safely embed your video on websites using <video> tags or platforms like Free2z.
