**Starting with AGC077 on 3/29**, submitting a recording will be required in order to earn a **GP30 score**. For basic information about GP30 scores and AWTF2027, please refer to [this article](https://atcoder.jp/posts/1636). The detailed rules regarding recordings are as follows. ## Recording Requirements * Participants must record their **entire screen** during the contest. However, it is acceptable for part of the screen to be covered by a camera feed, as shown in the example below. Even in that case, be careful not to obscure important areas such as coding or program output. * If multiple monitors are used, all of them must be recorded. * However, if a tablet is used for notes or scratch work, recording it is not required. * No specific screen resolution is required, but the text must be legible. * The frame rate must be at least 10 FPS. * In addition to the screen recording, you must also **record yourself during participation**. * The format does not matter, such as recording your face with a webcam or your full body with a smartphone, but it must be possible to verify that you yourself are participating. * Audio is not required for either recording. * The screen recording and the recording of yourself may be submitted separately, but combining them into a single video is recommended. * As an example of a valid recording, please refer to [this video](https://youtu.be/XX8b92SrXek). ## Operation * If you do not wish to receive GP30 points, you do not need to submit a recording. Your rating will still change even if you do not submit a recording. * Participants who wish to receive GP30 points must, if they place within **50th** in a GP30-eligible contest, upload their recording data to an online storage service or video-sharing service and submit the URL. Specifically, register for [this dummy contest](https://atcoder.jp/contests/proctoring-submission) and submit the URL there to the only problem using **Text (cat)**. You may include additional information besides the URL, but do not write anything irrelevant. * The recording data does not need to be publicly available. For example, an unlisted YouTube video satisfies the requirement. * Participants who place in the top 50 will be notified by email. In addition, if rankings change due to bans or similar actions, participants who newly move into the top 50 will also be notified by email. Please note that **these emails cannot be received unless “Receive important emails” is enabled in your user settings**. * Recordings must be submitted **within 24 hours after the notification email is sent**. Note that recordings may be submitted at any time regardless of rank, so if there is any possibility of earning points, we recommend submitting immediately after the contest ends. * Among the participants within the top 50 who submitted a valid recording, GP30 points will be awarded to the top 30. Even if fewer than 30 participants are eligible to receive points, **there will be no roll-down**. ## FAQ * Q: Is it acceptable if there are periods when I do not appear in the recording? In particular, may I go to the restroom during the contest? A: Yes, that is not a problem. However, if excessively unnatural absences stand out, the points may be invalidated. * Q: Can I still receive points if part of the recording data is corrupted? A: Depending on the extent of the corruption, points may still be awarded even if the recording is not completely intact. If you are unsure, please submit the recording. Including an explanation of the situation may work in your favor.
