🔥 DESCRIPTION 🔥

so MP4DeleteTrackEdit deletes the specified track edit segment. that's it. that's the function.

⚠️ okay but the tea here is IMPORTANT: since editId's form a sequence, deleting an editId will cause all edit segments with editId's greater than the deleted one to be reassigned to their editId minus one. so everyone downstream shifts up one spot. it's giving group chat when someone leaves and everyone's nickname in the list shifts. 😭

also — and this is the part that lowkey matters — deleting an edit segment does not delete any media samples. the samples stay. untouched. unbothered. main character energy. ✨
