FAQs
Can AI really create videos?
Yes — AI can generate short-form videos with visuals, captions, and voiceovers.
What platforms does this support?
You can create videos for TikTok, Instagram Reels, and YouTube Shorts.
Do I need editing experience?
No — AI handles most of the creation process automatically.
Can I schedule videos after generating them?
Yes — you can send videos directly to your Postly scheduler.
How does the AI generate videos from just text?
The AI uses natural language processing to understand the core themes of your script. It then matches those themes with relevant visual elements and generates a synthetic voiceover. It also automatically creates and syncs captions, which are essential for the 'sound-off' viewing habits common on mobile social media platforms.
Which video formats and platforms are supported?
The generator is optimized for vertical video formats (9:16), making it ideal for TikTok, Instagram Reels, and YouTube Shorts. By focusing on these high-growth formats, the tool ensures that your content meets the specific technical requirements and audience expectations of the most popular short-form video platforms.
Do I need to download the video to post it on social media?
No, you do not need to download the file. One of the primary benefits of using Postly is the direct integration with our social media scheduler. After generating and editing your video, you can schedule it to be published automatically to your connected social accounts, saving you significant time and storage space.
