3. The method of claim 2 , wherein generating the metadata file for at least the portion of the media content includes:

determining, using the one or more machine learning models, at least one of the character depicted in at least the portion of the media content, the facial expression of the character depicted in at least the portion of the media content, the object depicted in at least the portion of the media content, and the action occurring in at least the portion of the media content; and

generating the one or more metadata descriptions for at least one of the character depicted in at least the portion of the media content, the facial expression of the character depicted in at least the portion of the media content, the object depicted in at least the portion of the media content, and the action occurring in at least the portion of the media content.

4. The method of claim 1 , further comprising:

determining, using a machine learning model, a first character and a second character depicted in at least the portion of the media content;

adding the first priority score and the second priority score to the metadata file.

5. The method of claim 4 , further comprising:

determining the first priority score is higher than the second priority score; and

based on determining the first priority score being higher than the second priority score, generating the text description of the scene of the media content using audio data associated with the first character.

6. The method of claim 1 , further comprising:

generating one or more metadata files for a plurality of portions of the media content, each metadata file of the one or more metadata files being associated with a corresponding timestamp within the media content.

7. The method of claim 1 , wherein generating the plurality of sentences using the one or more metadata descriptions includes:

determining a subset of metadata descriptions from the one or more metadata descriptions having confidence scores greater than a confidence threshold; and

generating the plurality of sentences using the subset of metadata descriptions having confidence scores greater than the confidence threshold.

8. The method of claim 7 , further comprising:

discarding one or more metadata descriptions from the one or more metadata descriptions having a confidence score greater than the confidence threshold.

9. The method of claim 7 , wherein generating the plurality of sentences using the subset of metadata descriptions includes:

obtaining a plurality of template sentences, each template sentence of the plurality of template sentences including one or more placeholder metadata tags; and

replacing placeholder metadata tags of the plurality of template sentences with the subset of metadata descriptions having confidence scores greater than the confidence threshold.

10. The method of claim 1 , wherein annotating the media content using the text description of the scene of the media content includes:

generating an audio file using the text description.

11. The method of claim 10 , wherein generating the audio file includes converting the text description to an audio description, and further comprising embedding the audio file into a file of the media content.

12. The method of claim 1 , wherein annotating the media content using the text description of the scene of the media content includes:

generating a media summary of the media content using the text description.

13. A system for annotating media content, including:

a memory; and

one or more processors coupled to the memory and configured to:

obtain media content;

generate, using one or more machine learning models, a metadata file for at least a portion of the media content, the metadata file including one or more metadata descriptions;

generate a plurality of sentences using the one or more metadata descriptions;

determine, using a machine learning model, a corresponding sentiment associated with each sentence of the plurality of sentences;

compare the corresponding sentiment associated with each sentence of the plurality of sentences to a sentiment associated with at least the portion of the media content;

determining a subset of sentences from among the plurality of sentences to generate a text description of a scene, wherein the subset of sentences are within a sentiment threshold of the sentiment associated with at least the portion of the media content; and

annotate the media content use the text description of the scene of the media content.

14. The system of claim 13 , wherein each metadata description of the one or more metadata descriptions is associated with at least one of a character depicted in at least the portion of the media content, a facial expression of the character depicted in at least the portion of the media content, an object depicted in at least the portion of the media content, and an action occurring in at least the portion of the media content.

15. The system of claim 14 , wherein the one or more processors are configured to:

determine, use the one or more machine learning models, at least one of the character depicted in at least the portion of the media content, the facial expression of the character depicted in at least the portion of the media content, the object depicted in at least the portion of the media content, and the action occurring in at least the portion of the media content; and

generate the one or more metadata descriptions for at least one of the character depicted in at least the portion of the media content, the facial expression of the character depicted in at least the portion of the media content, the object depicted in at least the portion of the media content, and the action occurring in at least the portion of the media content.

16. The system of claim 13 , wherein the one or more processors are configured to:

determine, use a machine learning model, a first character and a second character depicted in at least the portion of the media content;

determine a first priority score for the first character and a second priority score for the second character; and

add the first priority score and the second priority score to the metadata file.

17. The system of claim 16 , wherein the one or more processors are configured to:

determine the first priority score is higher than the second priority score; and

based on determining the first priority score is higher than the second priority score, generate the text description of the scene of the media content using audio data associated with the first character.

18. A non-transitory computer-readable storage medium having stored thereon instructions that, when executed by at least one processor, cause the at least one processor to:

obtain media content;

generate, using one or more machine learning models, a metadata file for at least a portion of the media content, the metadata file including one or more metadata descriptions;

generate a plurality of sentences using the one or more metadata descriptions;

determine, using a machine learning model, a subset of sentences from the plurality of sentences to generate a text description of a scene of the media content; and

annotate the media content use the text description of the scene of the media content.

19. The non-transitory computer-readable storage medium of claim 18 , wherein each metadata description of the one or more metadata descriptions is associated with at least one of a character depicted in at least the portion of the media content, a facial expression of the character depicted in at least the portion of the media content, an object depicted in at least the portion of the media content, and an action occurring in at least the portion of the media content.
