Q: What if the video plays fine on my phone but not after conversion?

A: If they’re embedded, yes. If they’re external (like .srt), they might need re-syncing.
Q: Can I change the video resolution when converting?
A: Yes, you can downscale or upscale during conversion—great if you’re saving space or prepping for a bigger screen.

A: Yep—downscaling from 4K to HD is super common, especially when you’re trying to save space or make uploads faster.
Q: Can I convert a video to black and white?
