When you think of video editing, you may first think of large video processing software such as After Effects, Premiere, Edius, Vegas and so on. However, these software are not easy to learn. In fact, in addition to these large professional software, we can also choose more easy to use video processing tools. For example, using an open source video processing software Shotcut, you can complete most of the common video processing tasks.
1. Automatic reminder to convert to the best format before editing
After running the software Shotcut, first add the video files to be processed. When adding a video, if the software detects that the existing video file is of variable frame speed (unreliable for video editing), it will remind to convert the file to a format more suitable for editing.
At this point, the slider at the bottom allows you to choose from three grades of formats. Good” is the lossy H.264/AAC MP4 format with medium file size; “Better” is the slightly lossy ProRes/ALAC MOV format with larger files; “Best ” is the lossless FFV1/FLAC MKV format, with the largest file size (Figure 1).
2. Identify the video file properties at a glance
To work with a video, we first need to know the properties of the video file. What kind of video file is encoded, what is the resolution and frame rate, and what is the encoding, sample rate, and format of the included audio file. All these parameters can be viewed very easily in Shotcut. After opening the video file to be processed, click the “Properties” button on the toolbar to open the video properties window, and in the video file properties window, click “Video”, “Audio” and “Metadata” respectively. In the video file properties window, click on the “Video”, “Audio” and “Metadata” tabs respectively, and you can view the various parameters at a glance (Figure 2).
Tip: If you do not find the toolbar in the window, click the View menu and select the Show Toolbar command item to open the toolbar (Figure 3).
3. Apply filters to create various special effects
When we usually watch video programs, we often see some video special effects, such as nostalgic style screen, gradient screen, etc. In fact, this is the result of applying filters. In fact, these are the results of applying filters. In Shotcut, it is very easy to apply various filter effects. After opening the video file, click the “Filters” button on the toolbar, and then click the “+” button in the middle of the “Filters” pane to open the filter selection list (Figure 4).
There are four buttons at the bottom of the filter list, the two middle ones are for video and audio effects filters, the first asterisk button is for filter collection, and the last one is for deleting a filter. Once you select a filter, you can apply the selected filter to the current video. In the filter list we can select some common effect adjustment filters, such as adjusting white balance, brightness, adding text, fade-in and fade-out effects, and so on. In addition, you can also select a number of special effects. For example, select one of the “Old Movie: Noise” filters to give the selected image an old movie effect (Figure 5).
Tip: The specific effect can also be fine-tuned during the process of selecting and previewing the effect.
4. editing and merging Use the timeline function
Editing and merging video clips is also a common task in video editing and processing. These operations can be done using the timeline. After loading the video file to be processed, click the “Timeline” button on the toolbar to open the Timeline settings pane (Figure 6).
In the timeline pane, you can complete video dubbing and audio/video compositing operations by inserting and adding audio tracks and video tracks through the timeline menu commands, timeline toolbar and slider dragging, etc. used together. The video editing operation can be completed by executing the crop command on the video of selected clips. 5.
5. Output conversion Generate different format files
Shotcut can be used as a universal video format converter to provide the file formats we need. After opening a video file for editing, click the “Output” button at the end of the Shotcut toolbar to open the file output settings window. In this window, you can customize the output of video formats by customizing various parameters. First, select the output file format from the “Format” list, and you can see that the list includes a very rich variety of video file formats (Figure 7).
Click the “Video” tab to customize the resolution, aspect ratio, frame rate, scan mode, interpolation mode and other parameters of the video; click the “Encoder” tab to select the type of encoder used, bit rate control scheme, quality percentage and other parameters; click “Audio” tab, set the audio sample rate, choose the encoder and bit rate control scheme and the specific value of the bit rate. If you do not need audio rendering, click the “Disable Audio” checkbox (Figure 8).
After the parameters are set, save the output file. This allows you to personalize the settings and conversion of the video file.
