We are inviting all Steam partners who have appropriate video content to use the Steam Video platform.

  • Frame Rates: up to 60 fps (must be progressive, non-interlaced)

Lisätietoja
  • Please ensure 5.1 sound channels are mapped correctly (C, L, R, Ls, Rs, LFe).
  • Steam does not require both Stereo and Surround unless the mixes are markedly different.
  • When preparing alternate audio tracks (audio dubs, commentary tracks, etc.) the audio running time must be the same running time as the source video file.
  • The language of the audio will be used to determine if an audio dub or subtitles should be automatically enabled. The language can be set on the Video Management page after the video has been ingested.

  • Supported Languages: Arabic, Brazilian, Bulgarian, Czech, Danish, Dutch, English, Finnish, French, German, Greek, Hungarian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Romanian, Russian, Simplified Chinese, Spanish, Spanish-Mexican, Swedish, Traditional Chinese, Thai, Turkish, Ukrainian, Vietnamese.

Notes
  • Subtitle and Caption files are uploaded directly into the Video Management section of your video app after the video file has been ingested successfully.
  • Captions for the deaf or hard-of-hearing (SDH/CC) and Subtitles for languages are supported for all languages.
  • Captions and subtitles must be uploaded in the WebVTT format. For format conversion tools, please see the Video Preparation Tools section for the program Subtitle Edit.

  • We often find videos encoded at 23.976 fps have subtitles that are encoded at 24 fps and those subtitles will drift out of time over the course of playback. While other video platforms may correct these for you, Steam won't. Please ensure your subtitles are created at the same frame rate as your video itself.
