Video export on x-rush.ai is deliberately narrow: one fixed deliverable per export, and no codec, container, resolution, bitrate, or quality-preset pickers anywhere in the flow. Video Studio turns a selected result or composition draft (clip order, trims, sound, subtitles, aspect, cover) into that file; Meme Video ships one standard MP4 per candidate.
One File, One Spec
Every export is an H.264/AAC MP4: no WebM, MOV, H.265, ProRes, project package, or GIF side-exports. Maximum, Balanced, and Web Optimized presets are not on the menu either; the delivered file uses one fixed encoding. Resolution follows current capability, 720p or 1080p for Video Studio private delivery, and stops there. No 4K. Downloading the untouched original and exporting a modified cut are separate actions, and a delivered cut is genuinely re-encoded from your choices, through the same mapping the preview used.
What You Can Set
Trims keep one continuous start-and-end range; splitting, transitions, and speed changes are out of scope. Subtitles can be auto-generated (a 0.5-credit text unit, confirmed before it runs), hand-edited, imported as SRT, and burned in; everything after recognition is free. Covers come from a picked frame or an existing image. Video Studio works in 16:9, 9:16, and 1:1; a composition mixing aspect ratios defaults to fit-with-borders with an explicit center-crop alternative, and nothing stretches. Meme Video has no aspect selector, since output follows the reference image or the template video.
Watermarks: Private Originals, Public Copies
Private workspace results and your own downloads carry no brand watermark, on every plan including Free. The x-rush.ai watermark belongs to public delivery copies: publish to Community or Explore and the public player, previews, and guest downloads show your author identity beside the platform mark. Visitors receive that watermarked copy, never your clean original. Watermark removal is not a plan perk; plans differ in credits, concurrency, and storage.
Costs and Retries
Generation is the billable step, one video unit at 10 credits per accepted task. Exporting is deterministic processing that creates no generation unit and spends no credits. A failed export keeps the draft and retries free; each explicit export adds a fixed version to Results without overwriting earlier ones.
