8. Generating voiceovers (Elevenlabs API)
9. Working directly with APIs through HTTP requests (Pexels API)
10. Processing images, animating, and generating videos (Pillow, Moviepy, Numpy)
After solving this task, you will have:
1. Strong Python programming skills with a focus on practice
2. A powerful bot that includes modules for text, AI images, voiceovers, and video generation
3. A foundation for building powerful OOP bots for other projects | 629 |
| 4 | The course is complete.
Next, let's summarize the course and what we have learned. | 18 |
| 5 |  You should end up with video files like this.
* For now, adding transitions and subtitles can be something for you to think about. | 600 |
| 6 | The output of this class should be video files where:
1. For each scene, image animations are performed based on the duration of the audio file.
2. Images are scaled and cropped to the required video size, considering animation shifts.
3. Video footage is merged if available in the folder. The footage is scaled to the video size.
4. Each generated video file has its respective voiceover audio file merged.
5. The generated video fragments of each scene are combined into one final video file. | 557 |
| 7 |  Image Animation and Scaling Methods:
1. For image animations, you need to write separate methods. Some possible animations include: zoom_in, zoom_out, slide_left_to_right, slide_right_to_left, slide_top, slide_bottom, circular_motion.
2. Before performing the animation, the image must be scaled and cropped (using Pillow). This requires writing a separate method. The scaling should account for shifts happening during the animation to prevent black unfilled areas from appearing.
3. The numpy library is used for performing animations. Numpy helps transform the image into a pixel array, making it faster and easier to manipulate.
* An example implementation of the zoom_out method is shown in the image. | 489 |
| 8 | Method execute:
1. Iterate through each element of the list (dictionary).
2. Extract the paths to all media files from the dictionary and save them in variables.
3. Calculate the duration of the audio file:
audio_clip = AudioFileClip(audio_path)
duration = audio_clip.duration
4. Based on the duration of the audio file, calculate and perform the animation of the image.
You can add a logic to relate the duration of the audio file to the number of images. For example, if the duration of the audio file is less than 3 seconds, use one image; if it's longer, use two images.
5. To implement the joining of video footage, check for the presence of a video file in the folder. If a video file exists, the image animation is not performed, and the video file is joined instead.
6. After performing the animation, merge the video file with the audio file.
7. After completing the loop, combine the finished video segments from each scene into one final file.
8. Save the final video file in the generated_videos folder. | 390 |
| 9 | Data Preparation:
1. Loop through the folders containing materials for each script (script_1, script_2, script_3), located in the generated_images folder.
2. For each folder, loop through the subfolders with scenes (scene_1, scene_2, scene_3).
3. In each subfolder, pack the paths to all files into a dictionary. Example of a dictionary:
files = {'image_1': 'path', 'image_2': 'path', 'image_3': 'path', 'voiceover': 'path', 'footage_1': 'path', 'footage_2': 'path'}
4. Return a list of lists of dictionaries. Each list of dictionaries represents a script, and each dictionary contains file paths for a specific scene.
5. Loop through each list (script).
6. Pass the LIST OF DICTIONARIES to the execute method. | 367 |
| 10 | VideoGenerator
To implement this class, we will need the following tools:
• Pillow – for image processing (scaling and cropping)
• Moviepy – for merging video clips and audio files
• numpy – for creating animations and converting images into arrays
Command for installation:
pip install pillow moviepy numpy | 377 |
| 11 |  Before developing the final class VideoGenerator, the project structure should look as follows. | 405 |
| 12 | Way to obtain key phrases for a scene:
1. Read the file(s) containing the divided scenes of the script (script_scenes.csv).
2. Take the text of the 3rd or 4th scene for each script.
3. Create a writer object and send a request to the AI assistant, asking it to return a list of key phrases from the text. Request the format to be a Python dictionary or list.
4. Extract the elements of the dictionary or list.
5. Loop through the elements, for each element call the execute method and pass the key phrase into it. | 372 |
| 13 | Method execute:
1. Accept an argument containing the search keyword for the video (query), and also set the parameters page, per_page, orientation with default values:
def execute(self, query, page=1, per_page=10, orientation='portrait'):
2. Form the endpoint path:
endpoint = 'https://api.pexels.com/videos/search'
Alternatively, set it as an object attribute: self.endpoint.
3. Create a dictionary with parameters:
params = {'query': query, 'page': page, 'per_page': per_page, 'orientation': orientation}
4. Send a request to the target endpoint by calling the make_request method and passing the endpoint and parameters.
5. Obtain the JSON response from the request.
6. Extract video links from the JSON response.
7. Save several videos in the folder for the 3rd or 4th scene of the script. | 354 |
| 14 |  Next, create a method for sending a request (make_request):
1. The method takes an endpoint and request parameters.
2. Then, the headers for the request are formed. This is a dictionary containing the key 'Authorization' and the value of the API key.
headers = {'Authorization': self.api_key}
3. A get request is made to the endpoint, with the parameters and headers set.
4. The method returns the JSON response.
An example of such a method is shown in the image | 323 |
| 15 | Let's start developing the FootageDownloader class.
We will insert the video footage in the middle of our Shorts.
A 40-second Shorts usually consists of 6-7 scenes. Therefore, we will save the footage file in the folder for the 3rd or 4th scene.
Class constructor:
1. In the class constructor, accept the API key.
2. Create an attribute self.api_key and assign it the value of the passed argument. | 318 |
| 16 | 3. Sending Requests
Requests to the Pexels API are sent via HTTP, most often using the GET method to retrieve data. For each request, you need to include a header with your API key and additional parameters.
Example request:
• URL (endpoint): https://api.pexels.com/videos/search
• Header: Authorization: <your_key>
• Request parameters:
- query — search term (e.g., "nature").
- per_page — the number of results returned per page.
- page — page number for pagination.
4. Handling the Response
The API response contains JSON data, which must be processed to extract the video file links. | 339 |
| 17 | FootageDownloader
To download footage, we will use the Pexels API.
Developing this class will teach you how to work directly with service APIs.
Working with the Pexels API (or any other API) typically involves the following steps: obtaining an API key, reviewing the documentation, sending HTTP requests, and handling the responses.
Let's go through these steps using the Pexels API to download videos.
1. Obtaining an API Key
Register on the Pexels website and obtain an API key from your account.
https://www.pexels.com/api/
2. Reviewing API Documentation
The documentation provides all available endpoints, request parameters, example responses, and header requirements.
https://www.pexels.com/api/documentation/ | 365 |
| 18 |  After generation, the voiceover files for each scene of each script should be saved in the same folders where the images are saved. | 400 |
| 19 | Hint 1: Obtain the API key on the ElevenLabs website and save it in a .env file. Then, when creating a VoiceGenerator object in the main.py file, retrieve the API key from environment variables through the Config class attribute (Config.ELEVENLABS_API_KEY) and pass it to the class constructor.
Hint 2: You can get the available voice names on the page https://elevenlabs.io/app/speech-synthesis/text-to-speech or by using the method voices:
self.client.voices.get_all() | 373 |
| 20 | Data for passing to the execute method can be prepared like this:
1. Read the data from the file(s) where the divided script scenes are saved (script_scenes.csv).
2. Return a list of lists. Each list is a script. Each scene is an element of the list (a string or a dictionary key).
3. Loop through each list (script).
4. Loop through each element (scene) and pass it to the execute method. | 365 |
