Media Guidelines

Different social platforms have different requirements for media. PostSyncer will automatically process your media to meet platform requirements, but keep these limitations in mind:

Video cover images

Set content[0].cover_image when updating a video post. Only the first content thread’s cover is applied when publishing.

Platform requirements for cover images

Platform	Cover method	API field
TikTok	Frame selection from video only	`video_cover_timestamp_ms`
YouTube	Custom thumbnail upload only	`thumbnail`
Instagram (Reels)	Custom thumbnail upload only	`thumbnail`
Facebook (Reels / video)	Custom thumbnail upload only	`thumbnail`

TikTok: use video_cover_timestamp_ms only — no custom thumbnail upload. YouTube, Instagram, Facebook: use thumbnail only — upload a cover image to the media library (or pass a public image URL).

Platform	Max Images	Max Videos	Required Media	Max File Size
Twitter/X	4	1	No	5MB (img), 512MB (video)
Facebook	10	1	No	10MB (img), 4GB (video)
Instagram	10	1	Yes	8MB (img), 100MB (video)
TikTok	35	1	Yes	20MB (img), 4GB (video)
YouTube	0	1	Yes	N/A, 10GB (video)
Pinterest	5	1	Yes	20MB (img), 200MB (video)
Threads	10	10	No	8MB (img), 1GB (video)
Telegram	10	10	No	5MB (img), 20MB (video)
