One of the biggest problems I found while making my video was when there was constant lagging in my video playback when I wanted to view how my editing was working. I was lucky enough to come up with a way to decrease the lagging (in which when the video plays back, it stutters or is not lined up video to audio), which is what I am going to give a tutorial on now. This tip of rendering, which makes the playback as smooth as possible, became very helpful to me when making my video, which is why I decided to share it.
First, look at the sequence panel on the interface. If you notice, in the timeline above one of the clips, there is a red line (indicated by the white arrow), as opposed to the line being green like the clip preceding it. This means that the clip needs to be rendered, in order to decrease lagging.
In order to make the red line green, the clip must be rendered. In order to do that, you start by choosing where to start the render. Click on the timeline where you want to start (I chose where the red line started), and press i on the keyboard. This makes you choose the “in” for your video clip.
Next, to choose where to end the clip render, click on the time line where you want to make an “out” (the end of red line), and press o on the keyboard. Now you have established an “in to out” on the clip sequence.
Now that you have an “in to out,” you want to render the clip. Go onto the tool bar at the top, and click on Sequence, and then choose Render In to Out. This will render the video clip from where you chose your “in to out” in the sequence.
Then, after you click that, this window will automatically appear, showing the rendering of the clip, and how much time remains to render the clip. Longer clips take more time to render each frame.
When that is finished, notice that the line in the timeline that used to be red is now green, meaning the clip has been rendered. Now, when you playback, the video will not be lagging, or at least not lagging as much as it was before. Then, you can continue on with your project without losing your mind.
