Frequently asked questions
What are the file requirements for YouTube Shorts?
YouTube Shorts need to be in a 9:16 aspect ratio, and the video should be no longer than three minutes. Available format options include MP4, MOV, and AVI, but make sure the file size is under 2GB for the best upload experience.
Following these guidelines will ensure your Shorts are compatible with YouTube and optimized for mobile devices.
Is there a limit to how many Shorts I can create from one long video?
No, there’s no limit to the number of clips you can create from a single video. Using Captions, you can trim and crop your footage as many times as you want. This allows you to repurpose existing content efficiently, helping you connect with your audience without filming new material.
Plus, it gives you multiple pieces to share across different platforms, boosting your reach.
Can I add subtitles to my YouTube Shorts with Captions?
Yes, Captions makes it easy to add subtitles to your YouTube Shorts. You can write text captions manually or use automated options to sync subtitles with the video. To match your brand's style, customize the captions' size, font, color, and position.
Adding subtitles makes your Shorts more accessible to a broader audience and improves engagement, especially for viewers who may be hard of hearing or are watching without sound.
What AI can generate YouTube Shorts?
Captions has several AI tools that can help you generate YouTube Shorts. Here are a few options to choose from:
- YouTube Shorts maker — Upload long-form videos to Captions, and AI will scan the footage to look for the best highlight clips.
- Reddit to Video — Paste a link to a Reddit comment into the platform. Choose your background and voice, and AI will make a video narrating the comment.
- AI Creator — Our studio lets you pick from preexisting avatars or turn yourself into a virtual character. Using these creators, you can automatically make ads, skits, or other social media-worthy posts.
- AI Script — Even if you want to film yourself, AI can simplify the planning process. Share your idea with the platform, and it’ll write a script that you can customize or use as-is.
With Captions, content creation has never been easier.
