第 2 部分。如何在 Premiere 中进行加速

Adobe Premiere 是最优秀的视频编辑软件之一，如果您想加快视频速度，可以使用它。 Adobe Premiere 具有许多可用于编辑或增强视频文件的编辑功能。此外，它可以产生具有高分辨率和质量的强大输出。更重要的是，它提供了无限的多机位角度，如果您加快视频速度，这将是有益的。并且由于最新更新，将视频导入和导出到您的设备更易于管理。

此外，如果您想要一个具有响应速度的程序，Adobe Premiere 是一个很棒的应用程序。许多专业人士更喜欢使用 Adobe Premiere 来编辑视频或电影，因为它具有许多视频编辑所需的组织工具。此外，该程序可以在所有跨媒体平台上下载，包括 Windows 和 Mac。

如何在 Adobe Premiere 中进行加速：

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.
