Getting started with QuickSubs
The workflow with QuickSubs is simple and user-friendly. After I logged in, the platform immediately prompts to upload a video for caption generation.
Then it takes around 1-3 minutes for QuickSubs to process your video depending on how big your file is.
In my case, my 1 minute and 12 seconds video was ready in under a minute, from upload to caption generation. It’s surprisingly fast, making the whole process feel almost effortless.
I loved the result—it instantly resized my video to a short-form format, making it perfect for TikTok, Instagram Reels, and YouTube Shorts without any extra effort on my part.
What’s super interesting is that I also got really cool captions and tag recommendations for my video. They weren’t just accurate, but also engaging and well-optimized for short-form content.
You can fully customize your captions—tweak the font, color, and placement to match your style. Plus, if needed, you can manually edit the captions for even more control.
A video longer than a minute took less than two minutes to download, and it was instantly formatted for TikTok, Instagram Reels, and YouTube Shorts—no extra editing needed. Honestly, I thought it would take longer than that!
You can also save your work in case you need to edit it some time later in the future.
Overall, QuickSubs is incredibly easy to use—the entire process took me less than five minutes from upload to final download. The captions were spot on, and I didn’t have to edit a thing. This tool is a huge time-saver for anyone creating short-form videos.

Supported platforms and file formats
QuickSubs is designed for short-form vertical videos and supports the following file formats:
- Video formats: MP4, MOV, AVI
- Maximum duration: Up to 210 seconds (3.5 minutes)
- File size limit: 1,000MB
If your video isn't already in a short-form vertical format, QuickSubs automatically converts it when generating captions. This means you can upload horizontal or square videos, and the platform will adjust them accordingly—a useful feature for creators repurposing content.
The final exported video is provided in MP4 format, ensuring compatibility across all major social media platforms like TikTok, Instagram Reels, and YouTube Shorts.
Pricing
The pricing is more affordable than many other caption generators, and considering the quality, it’s a great deal—especially for anyone looking to try it out.
If you’re new to this kind of tool, QuickSubs makes it easy to get started with its simple and intuitive interface.
Best practices and tips in using QuickSubs
- Upload videos formatted for short-form content
Ensure your videos are in vertical (9:16) format, optimized for platforms like TikTok, Instagram Reels, and YouTube Shorts.
Optional: If you want space for captions without covering key visuals, consider uploading videos with extra margin at the top or bottom.
- Ensure that your video has high quality audio for better accuracy
AI-generated captions rely on clear speech. Reduce background noise and use a good microphone to improve accuracy.
- Review and edit captions before publishing
While QuickSubs provides highly accurate captions, manual review helps fix any AI misinterpretations or timing issues.
- Experiment with different styles for different platforms
TikTok, Instagram Reels, and YouTube Shorts have different audience preferences. Test different caption styles to see what works best for engagement.
- Customize fonts and colors to match your branding
Consistency in fonts and colors across videos helps reinforce brand identity and makes your content more recognizable.
