What does "Well-received" mean here?

So I applied for a job, and at some stage, I had to record a 3 minutes video and send them. After sending the video, they replied to me: "Well-received". What does this mean? Does it mean that my application passed this stage, and they were pleased with the video? Or was it just a confirmation that they got the file?

English is my third language, and I am sorry this question might sound dumb to some of you. Lol
