The new sequence function is Premiere A common function in , The purpose is to determine the size and frame rate quality of video , Today, let's learn about the new sequence and parameter settings .

◆  ◆  ◆

There are many ways to create new sequences

pr Four ways to create a new sequence

Method 1 ：

Click... In the upper left corner of the interface “ file ” Options , Open one by one in the menu “ newly build ”、“ Sequence ”（ Or use the shortcut key is com/Control+N）

Method 2 ：

In the lower left corner of the material panel , Click on the arrow “ newly build ” term , Select... From the pop-up menu “ Sequence ”

Method 3 ：

In the project window “ Right click the stand-alone button ”, choice “ New projects ”-“ Sequence ”

Method four ：

When building a new project , Set the corresponding parameters of the material , Directly find the material you want to import , Drag into the timeline panel ;

In this way pr You can also quickly create a sequence that is consistent with the size of the material frame

ps： It is not recommended to drag materials directly into the material library , Because if the video uses some professional cameras, such as red taken , Dragging material directly into the material library may be divided into two parts , And if we double-click the material library to import , This will not happen .

Parameter setting of sequence

New sequence settings , We will see the following interface , The above information has been annotated , Next we will explain one by one .

1、 Frame rate

Popular said ,“ Frame rate ” It refers to the number of pictures in one second , The unit of frame rate is fps. for example “25fps” That is, every second 25 Pictures flow , Theoretically, the more pictures passed per second , The more fluent the video is .

2、 The resolution of the

Video resolution refers to the number of pixels contained in the video per unit length , With 1920×1080 For example , It has 1920 Pixel , share 1080 That's ok , Its resolution is 1920×1080, That's what we're talking about 1080p.

3、 Pixel aspect ratio

Pixel aspect ratio refers to the width of pixels (x) With Gao (y) The ratio of the . The square pixel ratio is 1:1; But not square （ rectangular ） The height and width of pixels are different . Pixel aspect ratio is similar to frame aspect ratio , The former is the aspect ratio of a single pixel , The latter is the overall aspect ratio of the image . The selection of pixel aspect ratio depends on what terminal your video file will be input on , If you just input it on the computer screen, of course, you should choose “ Square pixel ”, If you want to input on TV or widescreen TV , It is necessary to select the corresponding pixel aspect ratio , In order to avoid unexpected results .

4、 Field order

There are three options for field order ：

But in general, it is preferred “ No field ”,“ Play first ” and “ End first ” We won't discuss , Because it is rarely used by ordinary users .

5、 Audio sampling rate

Audio sampling rate refers to the sampling times of sound signal in one second , The higher the sampling frequency, the more realistic and natural the sound will be restored . On today's mainstream acquisition cards , The sampling frequency is generally divided into 22.05KHz、44.1KHz、48KHz Three grades ,22.05KHz It can only reach FM The sound quality of broadcasting ,44.1KHz In theory CD The boundaries of sound quality ,48KHz Is more accurate .

Several commonly used setting parameters ： 

Generally speaking , All we need to change are these two parameters —— Time base （ Frame rate ）、 Frame size （ The resolution of the ） , At present, it looks like a short video vlog These are uploaded to the platform , The resolution is generally 1920*1080, Frame rate 25 Frames per second .

For others, we can use the default settings , Just click OK . 

  Why do I need to create a new sequence

First of all , If you drag in the material when there is no sequence ,pr The parameters of the material will be automatically used as the video sequence , For example, we import a 1080p24 The frame of the video ,pr The automatically created video sequence is 1080p24 frame . But what if we drag in a 4k60 The frame of the video , Then our video sequence will become 4k60 frame , It greatly increases the volume of video , And if most of our later materials are still 1080p, That's not enough 4k The effect of .

second , If you drag the video directly into the timeline from the outside ,pr There are too many steps to deal with , There may be a crash , Especially when the volume of the original video is large .

In fact, building a video sequence seems simple , But it is easy to be ignored by us . But this is a mistake with big or small consequences , If we pay attention when we start editing , You can avoid these risks .
