第 2 部分。如何在 Premiere 中進行加速

Adobe Premiere 是最優秀的視頻編輯軟件之一，如果您想加快視頻速度，可以使用它。 Adobe Premiere 具有許多可用於編輯或增強視頻文件的編輯功能。此外，它可以產生具有高分辨率和質量的強大輸出。更重要的是，它提供了無限的多機位角度，如果您加快視頻速度，這將是有益的。並且由於最新更新，將視頻導入和導出到您的設備更易於管理。

此外，如果您想要一個具有響應速度的程序，Adobe Premiere 是一個很棒的應用程序。許多專業人士更喜歡使用 Adobe Premiere 來編輯視頻或電影，因為它具有許多視頻編輯所需的組織工具。此外，該程序可以在所有跨媒體平台上下載，包括 Windows 和 Mac。

如何在 Adobe Premiere 中進行加速：

Step 1. Download and install Adobe Premiere on your computer. After installing the program, open it on your device. The main thing you must do is to import the video file you want to speed ramp. You can click and drag your video from your files to your project window to import it.

Step 2. Next, drag the clip to the Timeline to generate a sequence in place. Then, Adobe Premiere will automatically create a sequence with the necessary settings you need for speed ramping.

Step 3. And then, select the part where you want to do the speed ramp. One of the ways that you can do to isolate the part you want to speed ramp is by setting in and out points. Press Command + K to cut the moment. Another method is using the razor blade tool to split the clip into portions.

Step 4. For the next step, we will create keyframes. But before we set the keyframes, we need to make sure that the keyframes are visible. Right-click your video clip and select Show Clip Keyframes,> Time Remapping > Speed.

Step 5. And on the Toolbar, select the Pen tool. Then, click the white line across your video clip to create a keyframe. You need two keyframes to perform speed ramping on your video. Set the first keyframe where you want to start the speed ramp and the other where you want to end the ramp.

Step 6. Now, we will adjust the speed of the part you want to speed ramp. Click the white line between the keyframes you set, and drag the white lines up or down. Drag up to speed up and drag down to slow down your video.
