Sounds like 95% of scientific studies these days. People always try to pick the best option given multiple items to select from. It's basically what you learn in persuasive argument courses - show the best evidence as it is not in your best interest to show the weakest evidence. If they altered it I would find that truly deceitful, but if they just picked the transcoded version that looked best they were just doing their job. Beyond that its just as likely they posted the first one they saw and had no intention to even find the "best" one.
