MP4 for tweet videos
MP4 is the standard container for video on the web. It combines H.264 video and AAC audio in a file that plays on phones, laptops, and TVs without conversion. When you download a tweet video through Doresa, you receive the MP4 stream X hosts.

MP4 for GIFs
GIF tweets look like animated images but X delivers them as short MP4 loops. This is why your GIF download has an .mp4 extension. The animation still loops in most players. Read how to download Twitter GIFs for steps.
M4A for Spaces
Spaces are audio-first. Doresa saves them as M4A, which uses AAC compression inside an MPEG-4 audio container. M4A is efficient for speech and widely supported. See how to download X Spaces.

What Doresa does not download
Doresa focuses on public video, GIF, Spaces, and broadcast media from X URLs. It does not offer a separate photo batch downloader or tools for other platforms such as TikTok, Facebook, or Reddit.
