videos are not syncing to iphone

I took some videos on my Iphone 6s. I downloaded them to my Imac via iphoto. I then trimmed the videos with quicktime. I then went to itunes and selected them to be synced to my iphone (by check marking the box that says "Sync Movies" and check marking the boxes of the movies). I then sync the Iphone- there doesn't seem to be any issues or errors, but...

They never appear in my videos folder on my iphone. Where are they on the Iphone? Am I missing something in the syncing process??
