Content ID is a system that identifies potential copyrighted content in videos by scanning uploaded videos for previously-uploaded content. The system will scan for audio, video, and images. If a match occurs, the original owner is notified and a Content ID claim is filed. The original owner can choose to do nothing, mute their audio in your video, block the video from being viewed, monetize the video, or track the video's viewership. Content ID claims are not necessarily a negative thing for your account. If you're fine with part of the audio being blocked or with ad revenue going to the original owner, you can decide not to do anything. The only time a Content ID claim can be negative is when the owner blocks your video globally. This can put your account in bad standing. If your claim was because of a song used in your video, you can try Youtube's automated removal tools to take the song out without having to re-upload the video: Open the Video Manager page and find the video you want to remove or swap the song from. Click the button next to "Edit" and select "Audio." Click "Remove this song" next to the Content ID'd song you want to remove. This may not be possible on all videos. Select a replacement track if you'd like from the YouTube Audio Library. Many of these songs are free to use and monetize. This is mainly for uploaders that create cover songs, and allows you to share revenue with the original owner: Find the video in your Video Manager. You can see which videos apply for this in the Monetization section of your account. Click the gray "$" button next to the video. This will only appear if the content owner has enabled the revenue sharing feature on their end. Wait for the request to be reviewed and approved. You will be notified if the owner approves sharing revenue. If you believe the Content ID claim is not valid, you can file a dispute. The claimant will have 30 days to respond to a dispute. You should only dispute if you believe your video was misidentified because you own or have rights to all of the content. If you dispute without a valid reason, you can receive a copyright strike. You can open it directly at youtube.com/my_videos_copyright. This will display what content was flagged by Content ID. If you still believe the claim was invalid, proceed. You'll only be able to continue if you select the last four options in the list. Only choose a reason that is actually true, or you will receive a copyright strike. These include: The video is my original content and I own all of the rights to it. I have a license or written permission from the proper rights holder to use this material. My use of the content meets the legal requirements for fair use or fair dealing under applicable copyright laws. The content is in the public domain or is not eligible for copyright protection. You'll be asked to review your choice and check a box to confirm that you're sure the claim is false. You'll be asked to type out a short summary of why you're filing a dispute. Make sure to clearly explain why you believe your video fits the description you picked above. Keep the message short and to the point. Don't worry about using legal language here, just write natural sentences explaining why you believe your video should not have a Content ID claim filed against it. This will formalize the claim, and it will be sent to YouTube for review. Filing fraudulent disputes can lead to your account being disabled.

Summary: Understand why you may have received a Content ID claim. Decide if you want to do anything. Use YouTube's tools to try to remove or swap the music. Enable shared monetization if you're a YouTube Partner and the video qualifies. Dispute a false or erroneous claim. Open the "Copyright Notices" page. Click the link next to your video to dispute the claim. Review what content was identified by Content ID. Select the reason that you believe the claim to be invalid. Confirm that you're sure the claim was a mistake. Enter a reason for your dispute. Check the box and type your name.

No matter what gymnastics move you're doing, you need to stretch first. You should at least stretch your ankles, hamstrings, neck, and wrists. To stretch your ankles, sit down on the floor. Prop one ankle up on the other knee, and rotate it in a circle a few times. Do the same with the other ankle. Stretch your hamstrings by pulling one leg up behind you while standing. Try to tighten your butt muscles while doing it. Switch to the other leg. Rotate your wrists and neck to get them stretched out. Run a couple of steps forward. An make sure you have good balance when doing so. On the last step, bring both feet together, and punch into the ground, pushing yourself into the air. You should land on the balls of your feet. As you push yourself into the air, lift your hands to your ears, so that you are keeping your core tight. You're not trying to flip right now. You're just practicing the jump. When you land, bend your knees slightly. Once you get the punch down, add in a knee lift then push your body foreword as you jump up, pull your knees up into the air. As you come back down, straighten back out. Bend your knees as you land. One safe way to practice these steps is on your trampoline in the back yard. You can go through each of the steps in this section on your backyard trampoline to get the feeling of the moves. When you start out on the trampoline, make sure you are tight. That is, keep your head steady and your body straight. You don't want your head and body flopping around, as that can lead to injuries. Start by getting a bounce going by jumping a little forward into a punch. Once you've got the punch down, try adding in the knee lift. Before doing a front flip, you want to make sure you're getting as much height as possible. Really punch off the ground when you're jumping. In addition, it's really best to work with someone if you've never done it before. Try a gymnastics or parkour gym to get some tips. In addition, you'll have access to things like spring floors at these gyms, making it a whole lot easier. Realize that if you're trying to do gymnastics as an adult, the consequences can be more severe than when you're learning as a kid. That is, as a kid, you only weigh 40 or 50 pounds when starting out in gymnastics, plus you're a lot more flexible. As an adult, you weigh a lot more, and you don't bend as easily. Therefore, it's easier for you to get injured. You probably shouldn't try a front flip if you have back or knee issues, at least not without consulting a doctor first.
Summary: Stretch first. Practice your jump first by doing a punch. Practice with a knee lift. Try practicing on a trampoline. Decide you're ready to do a front flip.
