Q: "Hope You Have A Good Day" is not six seconds, its twelve. You've labeled it wrong.
A: that's not true. the reason the looping videos are labeled that way is because they were originally written for vine, where they automatically loop, seamlessly. and the loop is 6 and a half seconds long (or less). When posting those videos to non-looping sites, it would be rude to just post it 1 time through with no loop, you would never get to hear how it loops. so in most cases, such as "chips", "letterman", "person", "how bout going to the mall", and many others, i sent it around twice on the nonlooped version so at least you can hear what it sounds like. but i chose to still label the length of the content based on the length of the material that loops. this is to clarify the fact that the second time through is not different in any way. you are seeing the same (in the case you mentioned) 6 seconds of content, repeated. there is only 6 seconds of content, but you are seeing it displayed twice because it is meant to be viewed in a loop. i hope that makes sense
