Export an Editor project to an MP4 the way the Export button does: the row of clips on the video lanes is joined (cuts, sound shapes, frames) with every sound clip on the audio lanes mixed in at its own second with its volume and fades, then the text layers, captions, logos, pictures, motion blocks, the look and the sound settings are rendered on top. Options as the Export menu offers them: resolution 480p / 720p / 1080p, frame rate 24 / 25 / 30 / 50 / 60, quality standard or high (AI ultra HD), bit rate, sound on or off, the frame ratio. Charged the same as pressing Export (a join and a render). Answers at once with an export id; call get_editor_export until it says complete with the file link. The file also lands in your library and in the project's Renders panel.
