Usually, it's 2 requests per video. Title and Description are two separate requests we send to the Google API. Please note that the description size is counted up to 300 characters. Anything above that counts as a separate request. So, for example, a video description of 500 characters would count as 2 requests, and a 1000 characters description would count as 3 requests. Therefore, keeping your descriptions shorter can help to conserve your translation requests. So, if your plan has 1000 translation requests, it means you can translate approximately 500 videos into one language, or 50 videos into 10 languages, assuming average descriptions are within the 300 characters limit.
