Which format is commonly used for video projects exported from Final Cut Pro?

The most commonly used format for video projects exported from Final Cut Pro is MP4. This format is highly versatile and widely supported across various platforms and devices, making it an ideal choice for sharing video content. MP4 efficiently compresses video files without significantly compromising quality, which allows for easier uploading and streaming. This is particularly important for online distribution and social media sharing, where file size and compatibility are paramount.

In contrast, the other formats listed do not serve the purpose of exporting video content. TXT is a text file format, primarily used for simple text documents with no video capabilities. JPEG is an image format used for photographs and graphics, while CSV is a file format used for storing tabular data, making it unsuitable for video projects. Therefore, MP4 stands out as the standard choice for exporting videos from Final Cut Pro, due to its efficiency and compatibility features.
