延时摄影是在快动作中显示通常缓慢过程的视频，例如天气变化或正在制作的画作。在 iPhone 的相机(Camera)应用程序中，有一个创建延时视频的选项，过程非常简单。这是在iPhone(iPhone)上创建延时视频的方法。
如何制作延时视频(How to Make a Time-Lapse Video)
在开始之前，请准备好您的延时拍摄对象。当然，此过程需要一些时间，但其中大部分只是在您捕获视频时等待。
请按照以下步骤创建视频。
- 打开 iPhone相机应用程序(Camera app)。
- 向左滑动，直到您到达延时(Time-Lapse)摄影机。
- 点击红色录制按钮开始录制您想要延时的内容。
- 当您想停止录制时，只需点击取代录制按钮的红色停止按钮。
- 延时视频将保存到您的照片(Photos)中。
手动执行此操作可能会导致播放视频时出现抖动或不清晰或断断续续等问题。但是，您可以采取一些步骤来制作出色的延时视频。
在 iPhone 上制作延时视频的技巧(Tips For Making a Time-Lapse Video on iPhone)
为了有效地使用这个 iPhone 相机功能，它可以帮助理解它是如何工作的。您还需要记住一些事项，以确保您的视频清晰且对观众来说看起来不错。
锁定自动曝光和自动对焦
您需要在按下录制按钮之前执行此操作。锁定曝光和对焦将有助于让您的延时在整个视频中看起来流畅。这是如何做到这一点的。
- 点击(Tap)并按住您希望 iPhone 相机锁定曝光和对焦的屏幕。
- 按住(Hold)直到在屏幕顶部 看到“ AE/AF Lock
- 然后，您可以继续拍摄延时摄影，锁定将一直存在，直到您再次点击屏幕。
延时视频的长度
只要您有电池电量和空间，您就可以无限期地录制延时视频。但是，无论您录制多长时间，一旦时间流逝，您的 iPhone 总会为您提供长达 40 秒的视频。
这是因为您录制视频的时间越长，iPhone 会在您录制时删除更多帧，以便将最终产品保持在此时间范围内。因此，您可以根据需要录制尽可能多的镜头，但无论如何，最长的是 40 秒。
但是，如果您不希望延时看起来太不稳定，最好将录制视频的时间限制为最多 30 分钟。
保持视频稳定
确保延时视频看起来不错的一个极其重要的部分是确保在录制时保持相机稳定。由于速度的提高，最终视频中将强调任何晃动。
有几种方法可以帮助您解决这个问题。首先(First)，您可以尝试将手机设置为在捕捉动作时无需握持手机，并且手机保持直立状态。您可以通过设置书籍并将手机靠在上面或使用其他任何东西来稳定手机来做到这一点。您也可以尝试使用带有智能手机适配器的三脚架，以保持 iPhone 稳定。
捕捉缓慢移动的过程
当您想要显示通常缓慢移动的事物被加速以查看随时间发生的巨大变化时，最好使用延时视频。它不是捕捉快速移动动作的好格式，因为最终，它可能会变成某种难以理解的模糊。
你应该使用延时摄影的一些很好的例子是天气，比如移动的云或雪，展示艺术或建筑项目的过程，或风景视频。
专注于主题
制作延时视频时，您需要确保在录制之前设置好镜头，因为这将是整个视频的唯一镜头。当观众观看延时视频时，他们希望能够尽可能多地看到主题，以便真正能够看到正在发生的过程。
因此，例如，如果您正在拍摄自己制作绘画的视频，您需要确保将整个画布放在框架中，并且您不会处于覆盖作品的位置. 说到(Speaking)这一点，您还需要确保没有任何东西妨碍对正在发生的过程的看法。花点时间进行设置，以便最终获得一个好的视频。
在 iPhone 上拍摄延时视频(Taking a Time-Lapse Video on iPhone)
iPhone 相机应用程序上的延时功能非常棒，可以以多种不同方式使用，以创建一些有趣的视频。如果您没有其他制作延时视频所需的设备（例如DSLR相机或视频编辑程序），它也是一个不错的选择。
如果您按照上面的说明和提示进行操作，您应该可以很好地制作精美的延时视频来展示(to showcase)您想要的任何过程。
How to Make a Great Looking Time-Lapse Video on iPhone
Time-lapses arе videos that show а usυally slow process in fast-motion, such as сhanges in the weather or a painting being made. On the iPhonе’s Cаmera app, there’s an option to create a time-lapse video, and the process is pretty simple. Here’s how to create a time-lapse video on yоur iPhone.
How to Make a Time-Lapse Video
Before starting, have your subject for your time-lapse ready. This process will take some time, of course, but most of it is just waiting while you’re capturing the video.
Follow these steps to create your video.
- Open the iPhone Camera app.
- Swipe to the left until you get to the Time-Lapse camera.
- Tap on the red record button to start recording what you’d like to time-lapse.
- When you want to stop recording, just tap on the red stop button that replaced the record button.
- The time-lapse video will save to your Photos.
Doing this by hand can lead to issues like shaky or unclear video or choppiness when you play it back. However, there are some steps you can take to make a great time-lapse video.
Tips For Making a Time-Lapse Video on iPhone
In order to use this iPhone camera function effectively, it can help to understand how it works. There are also a few things you’ll want to keep in mind to ensure your video is clear and looks good to viewers.
Lock Auto-Exposure and Auto-Focus
You’ll want to do this before you press the record button. Locking the exposure and focus will help keep your time-lapse looking smooth throughout the entire video. Here’s how to do this.
- Tap and hold on the screen where you want your iPhone camera to lock exposure and focus.
- Hold until you see “AE/AF Lock” at the top of the screen.
- You can then proceed to take your time-lapse and the lock will stay until you tap on the screen again.
Length of Your Time-Lapse Video
You can indefinitely record a time-lapse video as long as you have the battery power and space to do so. No matter how long you record, though, your iPhone will always give you an up to 40-second video once it’s been time-lapsed.
This is because the longer you record the video, the iPhone will delete more frames as you record in order to keep the end product within this time range. So, you can record as much footage as you want, but no matter what, the longest it will be is 40 seconds.
However, if you don’t want your time-lapse to look too choppy, it’s best to limit the amount of time you record your video to 30 minutes at most.
Keeping Your Video Steady
An extremely important part of making sure your time-lapse video looks good is making sure you keep the camera steady while recording. Any shaking is going to be emphasized in the final video because of the increased speed.
There are a few ways you can help with this. First, you can try to set up your phone in a way where you don’t have to hold it while capturing the action, and it stays upright. You can do this by setting up books and leaning your phone against it, or using anything else to stabilize the phone. You can also try using a tripod that has a smartphone adaptor in order to keep your iPhone steady.
Capture a Slow-Moving Process
Time-lapse videos are best used when you want to show something normally slow-moving being sped up in order to see large changes happening over time. It’s not as good a format for catching quickly-moving action, because in the end, it’ll likely just turn into somewhat of an unintelligible blur.
Some good examples of things you should use time-lapse for are the weather, like moving clouds or snow, showing the process of an art or building project, or landscape videos.
Focus On the Subject
When making a time-lapse video, you’ll want to be sure you have a good shot set up before you hit record, as it’s going to be the only shot for the whole video. When viewers are watching a time-lapse video, they’ll want to be able to see as much as possible of the subject to really be able to see the process taking place.
So, for example, if you’re taking a video of yourself making a painting, you’ll want to make sure you get the entire canvas in frame, and that you won’t be in a position where you’re covering the piece. Speaking of which, you’ll also want to make sure nothing is obstructing the view of the process taking place. Take your time setting it up so that you can get a good video by the end.
Taking a Time-Lapse Video on iPhone
The time-lapse feature on the iPhone camera app is a great one and can be used in many different ways to create some interesting videos. It’s also a good option to use if you don’t have other needed equipment for making time-lapse videos such as a DSLR camera or video editing programs.
If you follow the instructions and tips above, you should be well on your way to making a beautiful time-lapse video to showcase any process you wish.
