YouTube
Formats, media and text limits, options, inbox and analytics on YouTube.
Publish video and short to YouTube, read every post's numbers, and answer comments. Set a target's format, or leave it out and Rizamo picks one from the files.
Formats
| Format | Files | Text |
|---|---|---|
video | 1 video | 5,000 |
short | 1 video | 5,000 |
Media
Rizamo takes JPEG, PNG, WebP, MP4 and MOV files up to 4 GB. What YouTube takes:
- Images: JPEG or PNG, up to 2 MB.
- Video: H.264, HEVC, VP9 or AV1 with AAC or Opus audio, 1 to 60 frames a second, up to 3,840 px wide;
shortonly vertical (taller than wide).
| Format | Length | Size |
|---|---|---|
short | 1 s to 3 min | up to 4 GB |
video | 1 s to 12 h | up to 4 GB |
What Rizamo does to files
- Images: another type becomes JPEG or PNG; a larger file is compressed under 2 MB.
- Video: one YouTube does not take as it is (its codec, frame rate, width or size) is converted to H.264 and AAC within those limits. Its length cannot change: a video too short or too long for the format is refused when it is attached, as is a wide video for
short. - Your file itself never changes: the copy is made when the post goes out, and each target's
changessays what was done.
Text
- Up to 5,000, counted in bytes in UTF-8: an accented letter counts 2. Rizamo counts the same way, so
POST /v1/posts/validaterefuses what YouTube would. - The text is the video's description; its title is
options.youtube.title, or the text's first line, cut at 100 characters.
Options
Under options.youtube on a target. Each says which formats take it.
| Option | Type | What it does |
|---|---|---|
title | string | The video's title, 1 to 100 characters, without < or >. Left out: the text's first line, cut at 100 characters. The text is the description. |
privacy | public, unlisted, private | Who can watch it: public (YouTube's default when left out), unlisted or private. With publishAt, private. |
madeForKids | boolean | Whether the video is made for kids (YouTube's audience setting, COPPA). Required to schedule or publish, with no default: ask the person. Made for kids turns off comments and personalized ads on YouTube. |
tags | array of string | Keywords, at most 500 characters in all as YouTube counts them (a comma between tags, quotes around a tag with a space). |
categoryId | string | YouTube's video category id, such as 22 (People & Blogs) or 28 (Science & Technology). Left out, YouTube picks the channel's default. |
publishAt | string | When YouTube makes the video public, after Rizamo uploads it as private at the post's time (YouTube's own scheduling). In the future, and with privacy private or left out. To have Rizamo upload it later instead, schedule the post. |
isAiGenerated | boolean | Discloses realistic altered or synthetic content (YouTube's containsSyntheticMedia). |
