Opus Clip
Opus Clip turns long videos into short, viral clips using AI. It's built for fast repurposing, mainly for TikTok, Reels, and Shorts.
About
Opus Clip
If you’re a creator trying to pump out viral clips from long-form videos in minutes, Opus Clip feels like magic. Drop in a YouTube podcast, webinar, or talking-head video, and boom—it spits out a handful of short clips with snappy cuts and big captions, already framed for social. For speed demons and time-crunched creators, it’s a “drag and done” kind of tool that gets you clips without blinking.
But here’s where the magic wears off: you don’t get much say. You can’t pick the exact moment where your guest dropped that golden quote. You can’t finesse the captions or polish the pacing. Opus decides, not you. If you're an editor, an agency, or just someone who actually cares about tone and timing, this feels like handing your footage to a stranger and hoping for the best. So yeah—it’s fast. But is it your voice, your message, your brand?

Zubtitle
Zubtitle is a video captioning tool that helps creators add subtitles, headlines, and resize videos for social media.
About
Zubtitle
Zubtitle keeps it simple: your videos need captions, and most people watch with sound off anyway. Upload your video, let it transcribe, tweak the captions if needed, and choose from their pre-made styles. Throw in some headlines, progress bars, and resize for different platforms—done. It’s the no-nonsense approach to making your videos social-media ready with captions.
But here’s the thing—simple means simple. You won’t find cinematic transitions, layered b-roll, or more nuanced editing tools like fine trimming. It does captions and basic optimization, period. If that’s all you need, you’ll love how fast it is. If you’re chasing storytelling depth or a more polished final product, this probably won’t be your endgame editor.

Reviews
I’ve subscribed to and waded through the various capabilities of this program with workable results. However, there was a lot of self-tutoring involved since there weren’t such instructions forthcoming from the software.
This software is a break through in technology. It can sabe you tons of time by selecting portions of the video that identifies as potential to become a reel or short.
At first, this program was amazing, but with each system upgrade, it has gone from better to worse, and customer service is useless for me now. Give you an example, TikTok over the last 90 days, not one video has been accepted and requires editing, but when I download the same video clip from Opus and manually upload it to TikTok

Very easy to use. You get two free video credits with their watermark. You have the option to upgrade straight away or you can trial it using the credits
The ease of use for Zubtitle is incomparable. And trust me, I have made some comparisons.
It is very quick and easy to enhance our videos to a social media format, with headline and clear subtitles. I wish it was easier to change the colors.

Frequently asked questions
How does an AI clip maker work?
An AI clip maker scans long-form videos or podcasts using artificial intelligence to automatically identify the most engaging moments, then slices them into short clips with captions, animations, and transitions. It's a powerful way to repurpose content for platforms like TikTok and Instagram.
One thing to note is that an AI clip generator is not necessarily an AI video generator.
Can AI-generated videos be monetized on YouTube?
Yes, as long as your AI-generated videos follow YouTube's monetization guidelines and add original value—like commentary, visuals, or voiceovers—you can absolutely monetize them. AI tools help you create faster, but your creativity is still the magic ingredient.
How do I add a text-to-speech voiceover?
Most AI video editors have a text-to-speech option built in—just type your script, choose your AI voice, and click generate. It’s an easy way to add professional voiceovers to explainer videos, product demos, or tutorials without recording anything yourself.
How does text-to-video AI work?
Text-to-video AI turns written text prompts into fully edited video content—complete with visuals, animations, subtitles, and voiceovers. It automates video production so creators can go from script to video clips in minutes instead of hours.
How to switch the AI Avatar’s voice category?
Most AI avatar tools have voice categories based on tone or language—you just head to the voice settings and pick a different category (like professional, energetic, or friendly). It’s like casting the perfect voice actor, but instantly.
What are the top AI tools for generating video clips?
Top AI tools like Submagic, Pictory, and Descript make it incredibly easy to generate short clips from long-form content. They handle captions, visuals, templates, and even AI voiceovers—ideal for creators repurposing webinars, podcasts, or YouTube content into snackable, engaging videos for social media platforms.
