Image-only posts fail at the API
YouTube accepts video uploads, not standalone images. Schedulers that treat YouTube like Instagram send broken payloads and return confusing 422 errors.

Publish to YouTube automatically
YouTube is video-only: text posts fail. Content Drifter generates titles and descriptions, validates Shorts vs long-form specs, and rejects image-only uploads at the boundary so you get actionable errors instead of API 422s.

3 reasons publishing to YouTube manually is broken
Shorts vs long-form need different shapes
Shorts take vertical 9:16 video up to 3 minutes (60 seconds with music) with #shorts in the description. Long-form allows up to 12 hours. Mixing them wastes upload quota.
Title and description SEO is manual
The first 100 characters become the title; the full post becomes the description up to 5,000 characters. Writing both separately doubles production time.
What changes once YouTube runs on autopilot
Video-required guard (F189)
The publish pipeline rejects image-only YouTube posts at the boundary with a clear error, before Outstand or YouTube returns an opaque failure.
Shorts detection
Short content type enforces vertical video up to 3 minutes and can auto-append #shorts via youtubeConfiguration.
Connect YouTube on every plan
Connecting YouTube is free on every plan. Publishing there needs a video, and video starts on Lite. With a video attached, hands-off auto-publishing sends the scheduled post without you, inside your plan's monthly publish allowance.
Native OAuth
Connect your channel through Google OAuth with youtube.upload scope. Set default privacy and category per channel.
The YouTube rules we enforce before publish
Every limit below comes from our platform-rules source of truth, the same validator the publish pipeline uses before dispatch.
- 5,000 character limit (content + hashtags combined)
- Up to 15 hashtags recommended
- Video: mp4, mov, webm up to 256 GB, max 43200s
- Video file required: image-only posts blocked at publish
- Video uploads only, no text-only or image-only posts. Title is the first 100 chars of content; full content becomes the description.
Publishing to YouTube, start to finish
- 1
Authorise the channel with quota in mind
YouTube meters API access in quota units rather than request counts, and uploads are expensive. The connection records the channel and the pipeline spends quota deliberately, so a batch never strands half-uploaded.

Titles, descriptions and Shorts rules checked first
A Short has to be vertical and under the length ceiling to be treated as one, and a title over the limit is rejected at upload. Both are validated at draft time, along with the description and tag limits.

Uploaded resumably, then published on schedule
Video upload is resumable, so a dropped connection resumes instead of restarting. The video is staged and then made public at the slot, which means the publish moment is exact rather than whenever the upload happened to finish.
Frequently asked questions
How do I publish to YouTube automatically?
Connect YouTube from Platforms via Google OAuth (free on every plan), attach an MP4/MOV/WebM video in Final Review, and schedule or publish. Video starts on Lite. Title is derived from the first 100 characters of your content.
Can I auto-publish YouTube Shorts?
Yes. Select the Short content type for vertical video up to 3 minutes. The validator enforces duration and format; #shorts can be appended automatically.
Why can't I publish an image to YouTube?
YouTube's API is video-only. Content Drifter blocks image-only YouTube publishes intentionally so you fix the media before scheduling instead of debugging a 422 later.
Is YouTube auto-upload against YouTube terms?
Uploading via the official YouTube Data API with user-authorized OAuth is permitted. You retain ownership; Content Drifter acts as your scheduling client.
What video formats does Content Drifter support for YouTube?
MP4, MOV, and WebM per PLATFORM_RULES. Maximum file size follows YouTube's 256 GB API cap; Shorts are capped at 3 minutes.
