operational approach
0 1
Start PR software and create a new project, then create a new video sequence, and drag the video material into the sequence.
02
Let's look at the program window here, which shows the video, and there is a watermark at the lower right of the video screen; Watermark always stays in the same position.
03
Enter the effects panel, enter "Fast Blur" in the search box, search for "Fast Blur", and drag "Fast Blur" to the video track 1 on the sequence.
04
Move the mouse over the effect control and click the rectangle mask tool in "Quick Blur". Create a rectangular mask.
05
Look at the program here, put the mouse on the path of the mask and move the path to the watermark at the lower right.
06
Then, set the blur value in the Ambiguity Degree of Fast Blur. The larger the value, the stronger the blur.
07
When you play the video, you can see that the watermark of the whole video has been removed.
Median method
First, drag the imported video material to the timeline, select the video, expand the "Effect Control" in the upper left corner, and enter "Intermediate Value" in the input box under "Effect" in the right column. If you don't find the "effect", click the "window" in the top bar and put a tick in front of "effect", and the "effect" will appear.
Drag the "intermediate value" to the video material with the left mouse button, and you will find more "intermediate values" in the "effect control" in the left column.
Create a mask, change the size of the mask box to fit the watermark size, drag the mask to the position where the watermark is covered, and then change the size of the Radius under Median. After increasing the radius, you will find that the watermark is missing. This size is adjusted according to your own video material at that time, and there is no uniform size value.

Gaussian blur
Operation Step 1: Select the video layer to be removed, and add effect → video effect → blur sharpening → Gaussian blur. Of course, you can also directly enter Gaussian blur in the search box of the effect window.
Operation Step 2: Then in the effect control window, select the mask you need under Gaussian blur and place the mask on the watermark.
Step 3: Adjust the value to roughly match the video.
three
Image restoration
Operation Step 1: Copy a video layer upwards, select the copy layer, control the window of effect → opacity → draw a mask. The place where the mask is drawn here must have the same scene and color information as the place where the watermark is drawn.
Operation Step 2: Adjust the movement → position. In fact, drag the selected area to cover it and still operate in the control window.
Operation Step 3: Due to the color difference, you can adjust the exposure to the color panel, and then return to the matching mask to adjust the feathering.
This method is only suitable for fixed seats, and it needs enough color pixel information, just like in PS, and it needs an identical place to cover the scene matching, and it is not worn. That's why it's called picture restoration.
four
Enlarge video
Select the video and zoom directly in the control. Obviously, this method will make the composition very strange unless the project is urgent.
five
Add shielding
It's like a wide screen in a movie, with black edges sticking up and down. The high version steps are File → New → Title of the old version, find the rectangle tool, draw a black edge, go to the selection tool, press ALT to copy the black edge, then go to the project panel to find the subtitle 0 1 and drag it to the video layer, and adjust the length of the subtitle 0 1 to cover the whole video.
