I need a "flexible" program for creating video tests with a database

A program is needed to create video tests for social networks (horizontal and vertical videos).  

In general, a program with flexible settings is needed for quick test creation

What should be achieved in the end…..

Make the blocks universal, so that there is the possibility to include or exclude them, make them different sizes and colors, have the ability to move them (swap places), change the background (add a photo or video), change the font and color - Universality is needed to create such tests and have the ability to create videos with slight differences: transitions, overlays (backgrounds under text)

What we will have:

1) Test number

2) image

3) answer options

4) timer

5) question

6) explanation for the test

1) Test number - here I think everything is clear, just numbering

2) Image - if possible, when uploading an image, a contour appears around it (ability to change the color of the contour. Something like a background

3) Answer options - ability to provide 3-5 options, maybe even 3-4) Also, numbering of options ABCDE or 1,2,3.... and the ability to disable it) Here a support under the text is needed (solid or whatever is the correct term)

4) Timer, ability to set duration

5) question - a background is also needed

 about functionality

+ Tests are loaded by inserting text into the program

­+ Ability to mass upload tests, through a table or some other way (need your advice here)

+ Ability to customize the question text (it can be of different lengths) So that the background adjusts to the text, text alignment occurs on the background 

+ Answer options - setting the number of options, setting under the text (it can be of different lengths), creating a graphic background under the text and the ability to visually change it: rectangular with rounded corners or sharp corners, size, color)

+ Ability to set the timer (number of seconds)

+ ability to add music track to all videos

+ sound design, when an action occurs: the image appears, the countdown begins, the ticking of the clock starts, the correct option is shown, transition from one test to another

+ some transitions: fading, shifting or something else (ability to change transitions) 

(+) Ability to insert an explanation after the test, after showing the correct option all answer options are removed and the text with the explanation to the test is shown

(+) Ability to insert audio at a specific moment of the test. Let's divide one test into blocks

     -  we have a question 

     - answer options

    -  question with correct answer

    - explanation for the test (after showing the correct answer)

Ability to insert audio into these blocks, each with its own audio

Video output - ability to set the number of tests in the video, number of videos

Database

A database is needed to save tests for future use

- Ability to create categories

- When creating a test, I choose the necessary category and save the test there

- If I need to create a test, I choose the necessary category and how many questions to take from each category
