Best AI Video Tools for Social Media

Turning long video into short clips

OpusClip is the clearest leader here: it scores moments in a long recording, crops to vertical with speaker tracking, and adds captions. Descript approaches the same job from a transcript-editing angle, which suits interviews and podcasts where you want precise control over what gets cut.

The workflow that produces the most output for the least effort is recording one substantial conversation or walkthrough per week and clipping it, rather than filming individual short videos.

Editing and creating from scratch

CapCut covers templates, transitions, auto-captions, and export presets for every vertical platform, and its free tier is genuinely complete. Canva is better if the video sits alongside static design work and brand assets. Predis.ai generates short social videos from a text brief when you need volume more than craft.

• Burned-in captions on every clip, checked for accuracy
• A hook visible in the first frame, not just spoken
• Safe margins so text is not covered by platform UI
• Exports at the native aspect ratio for each channel

Distribution and measurement

Repurpose.io automates moving finished clips between platforms. Most schedulers — Buffer, Publer, Metricool, Vista Social — handle video publishing well enough that a separate distribution tool is only worth it at volume.

Judge video on completion rate and rewatches first. Views measure distribution; completion measures whether the clip was worth the time.
