Threads content leans conversational and authentic — production quality matters less than content quality
Keep videos under 90 seconds for the best completion rates
The text hook above your video drives plays — write a strong opening line in the post itself
Threads is a Meta app, so Instagram Reels-compatible formats (MP4, 9:16) work directly without conversion
What is the best video format for Threads?
MP4 with H.264 codec at 1080×1920 resolution (9:16 vertical) is the recommended format for Threads video. Threads is a Meta platform and shares format compatibility with Instagram. AAC audio and 30 fps are standard.
How long can a Threads video be?
Threads supports video posts up to 5 minutes long. For best reach and completion rates, keep videos under 90 seconds — Threads rewards shorter, conversational content more than long-form videos.
Can I post the same video to Instagram and Threads?
Yes — both use the same recommended format (MP4, 9:16, H.264). Since both are Meta platforms, the same video file works on both without conversion. Synchro lets you upload once and publish to Instagram and Threads simultaneously.
Synchro uploads your video to Threads and up to 7 other platforms simultaneously — free to start, no credit card required.
