Creating Screencasts
You’re free to choose any tool to create screencasts. It’s important, that you provide a .mp4 video of appropriate quality (resolution and presentation).
Your screencast should only show the action that triggered the reported bug in all situations and you should add the last few steps to reproduce if it's a bug report (usually adding 10 seconds to the video at most). Also, screencasts that are longer than 1 minute for Bug Reports and 15 seconds for Reproductions and User Stories will not be accepted unless they are really necessary to understand the bug or the video is long because of variables you can't control (such as a slow website response).
You should have your device sounds switched off unless required to understand the issue. Room noise such as other people's conversations, ambient music or animal sounds should not be recorded at all.

Note: videos must not be edited (except: "thinking aloud" videos or if you need to blur any sensitive information).
Best practices while capturing a screencast
Set up the device and the app or website before starting the recording. For example, if you're going to show a bug that happens after the registration form is filled and you tap on a button to go to the next step, it's best to fill in all information before starting the recording (such as the name, username, email and other fields) to save you some recording time.
Avoid hovering over screen elements for too long with your finger or your mouse. This behaviour can lead you to waste precious recording time. Usually, the viewer will be focused on watching your video so any actions taken or changes to the product will be noticed already.
Remember the time limits (1 minute for Bug Reports screencasts and 15 seconds for Reproductions and User Stories attachments). Since editing your videos is not allowed, instead of trying to fast forward your screencast to make it fit the limits you can check if you didn't record anything that's not actually useful to understand the bug. For the bug reports, normally only one or two extra steps (apart from the last one) are necessary to understand the bug. For Reproductions, you are only required to show the last step to reproduce the bug. Finally, for User Stories, you only need to show the results you've had (which usually means you also need to show only the last step or action taken by you to complete the User Story).
Remember to enable clicks and taps effects. To help the viewer understand which page elements are you interacting with, you are required to show the taps and clicks on your Desktop and Android devices.
Always watch your own screencast after submitting it. Since videos are computer files, they can corrupt when you're converting or uploading them. So opening your own videos and making sure they are good to be reviewed by others will help you to avoid rejections.
If you have the option while recording or converting your video, use preferably the H.264 codec. This is the most widely used codec currently in the world and will guarantee your screencast can be watched on many different devices.
