If you are trying to record gameplay from an older console without a capture card, your best bet may be using a video camera or your smartphone's camera app. You won't get perfect quality, but you'll still be able to record what you're playing. If you're using a smartphone, you'll have trouble picking up the sound from your TV. If you can, consider purchasing a capture device instead. These are external devices that you simply plug into your computer, making them much easier to install than a capture card. You will be able to record at the best picture and sound quality if you use a capture device. If you're playing a much older system, such as an NES or Sega Genesis, you may want to record with a VCR. This will lead to a better quality recording, and with the right equipment you can transfer it to a computer. The key to a good recording is to ensure that the entire frame is filled with the TV image. Try to position the camera in such as way that it is looking directly at the TV, and that the frame is filled by the TV image. Move the camera a little closer so that the edges of the TV are just barely cut off. This will ensure that the entire frame is full. Make sure that you aren't pointed at an angle, or you'll likely pick up some glare. If your video camera or smartphone uses digital zoom, avoid using it for filming your gameplay. Digital zoom will result in a blurry final video, and you need as much clarity as possible when filming this way. If you're using a camcorder, you may be able to route the game audio through the camcorder's input. You'll need a converter for the console's audio cable so that it can plug into the input or line-in option on the camcorder. This isn't possible on most smartphones. Another possibility with a camcorder is setting up a microphone next to your TV speaker to pick up the game audio more clearly. Make sure that no lights are shining directly onto the TV screen. You don't want to make the room completely dark, or the TV image will glow too much. As long as lights aren't pointing directly at the TV screen or camera, you should be good. The worst thing you can do for clarity is to try to hold the camera while the game plays. Your camera needs to be absolutely steady, or it will be very hard to see the gameplay. Use a tripod if possible. If you don't have a tripod, set the camera or phone on a level surface and stabilize it with books or other heavy objects. When the screen is dark, you may appear in the TV reflection if you are sitting directly in front. Sit off to the side while recording so that you don't get caught in the reflection. Once you're finished recording, transfer the video to your computer so that you can edit anything out that you don't want in the video. This is usually useful to cut out the setup process or to remove boring parts. Since the sound recording probably wasn't very good, you may want to replace the sound completely with a soundtrack. After you're finished making your edits, you can upload the video to YouTube or keep it on your computer

Summary: Know when to use this method. Frame the TV completely in the camera. Avoid using the zoom. Connect the audio to the camera (if possible). Dim the lights. Use a tripod or other stabilizer. Sit to the side while playing. Transfer the finished video to your computer for editing and uploading.

If you're new to doing a 180 on your skateboard or haven't done the trick in a while it's a good idea to get your body used to being in the proper position. Practice skating around for a bit by pushing off and then situating your body into the right position. The ollie is the most fundamental skateboard trick and it's incorporated into pretty much every trick you'll do. And the 180 is an ollie where you turn your board and body 180-degrees. For the 180 you'll be turning around either behind you for a backside 180, or in front of you for a frontside 180. Once you have the ollie down, you're well on your way to doing a 180 skateboard trick! If you ride "regular" you will have your right foot in the back positioned on the tail of the board. If you ride "goofy" then your left foot will be in back on the tail. You want to position your back foot on the tip of the tail. To do a 180 on the skateboard, you'll want to position your back foot on the corner of the tail. For a straight ollie your front foot will be centered about halfway up the board or slightly back. You also want to put more pressure on the outer edge of your foot (the side your pinky toe is on). To help you with turning, plant your front foot so its slightly hanging over the opposite edge of board from your back foot. This may feel awkward but it will help to keep your board balanced when you're in the air. Your shoulders and your upper body is where most of the work will come from when you perform your 180. By setting your shoulders correctly you will be able to turn your body quickly enough and this should allow your legs and the board to follow. You might be tempted to try and force the board to turn using mostly your legs, but you won't get enough torque this way. For a backside 180, position your front shoulder slightly in front of your chest and dip it down so when you pull up you have more momentum to work with. For a frontside 180, you want to position back shoulder in front of your chest and dip it down as well so you can pull up and create momentum. You don't want too much of a bend so that you end up crouching too low as that won't allow you to pop high enough. You should stand with relaxed knees like you're getting ready to hop slightly. If you are bending correctly you should be able to slide your front forward up the board with ease.
Summary: Practice getting into the ollie 180 position. Position your back foot for an ollie. Position your front foot for an ollie. Set your shoulders. Bend your knees.
