Using reliable news and primary sources, the claim that the highest quality video of the Moon was released by Artemis II is not true. News coverage, including reports from CNN, shows that NASA did release a new “Earthset” image from the mission, but this is a photo, not a video. The articles describe it as an important image, but they do not say anything about a record-breaking or highest quality video.
Looking at other news sources, the focus is on the mission itself and the images taken during the flyby. None of them mention any new Moon video being released. This suggests that the claim likely comes from videos or images online that have been mislabeled or taken from other sources.
Overall, the claim is false. NASA has shared some new images from Artemis II, but there is no evidence of any highest quality Moon video being released.
