Frequently Asked Questions

VideoSubtitle is an AI-powered video clipping platform that transforms long videos into viral short clips. Upload your video, and our AI identifies the most engaging moments, adds auto subtitles, and exports platform-optimized clips for TikTok, Instagram Reels, YouTube Shorts, and more.

Our AI analyzes your video content using advanced computer vision and natural language processing. It identifies engaging moments based on visual cues, audio patterns, speech content, and facial expressions. Then it automatically clips those segments and adds optimized subtitles.

We support most popular video formats including MP4, MOV, AVI, MKV, and WebM. For best results, we recommend uploading videos in 1080p or higher resolution. Maximum file size varies by plan - Free users can upload up to 500MB, while Business plans support up to 5GB per video.

VideoSubtitle exports clips optimized for all major platforms: TikTok, Instagram Reels, YouTube Shorts, Facebook Stories, LinkedIn Video, and X (Twitter) videos. Each export preset includes the optimal resolution, aspect ratio, and file format for the target platform.

We offer four pricing tiers: Free (3 clips/month), Pro ($15/month, 360 credits/year), Expert ($30/month, 840 credits/year), and Business ($60/month, 1800 credits/year). Annual billing provides significant discounts - up to 60% off monthly prices.

One credit is consumed per clip generated. A 1-minute clip typically costs 1 credit, while a 5-minute clip might cost 3 credits depending on the features used (subtitles, face tracking, etc.). The AI automatically estimates credit cost before processing.

Yes, you can cancel your subscription at any time. Your plan remains active until the end of your current billing period. After cancellation, you'll continue to have access to paid features until the period ends, then downgrade to Free plan.

Yes! Our Free plan gives you 3 clips per month forever, with no credit card required. This lets you test the platform and see the quality of AI-generated clips before upgrading to a paid plan.

Our AI subtitle accuracy is over 95% for English content in clear audio conditions. We support 20+ languages including Spanish, French, German, Japanese, Korean, Chinese, and more. You can also edit subtitles manually after generation.

Viral detection is our AI feature that analyzes each potential clip segment and predicts its engagement potential. It considers factors like hook strength, content novelty, emotional impact, and pattern recognition from successful viral videos. Clips are ranked by viral score to help you prioritize the best content.

Yes, our face tracking technology can detect and follow multiple faces in a video. For group videos, it will automatically frame all detected faces or prioritize the main speaker based on audio analysis. Face tracking is available on Pro plans and above.

Absolutely! You can choose between AI-generated subtitles, upload your own SRT/ VTT subtitle files, or write custom captions. We also support multiple subtitle styles, positions, and animations to match your brand.

Yes, security is our top priority. All videos are encrypted in transit and at rest. Your uploaded videos are automatically deleted after processing (within 24 hours by default, or immediately if you choose). We never use your content to train AI models. For Enterprise customers, we offer dedicated processing and custom data retention policies.

You own 100% of the clips you create using VideoSubtitle. We don't claim any rights to your content. You're free to use, modify, and distribute your clips on any platform for commercial or personal purposes.

You can delete your account from the Profile page under Settings. Account deletion removes all your personal data, uploaded videos, and generated clips. This action is irreversible - we recommend downloading any clips you want to keep before deletion.

Processing can fail due to several reasons: unsupported format, corrupt file, file too large for your plan, or network issues during upload. Check our supported formats list and ensure your file meets the requirements. If problems persist, contact support with your video ID.

Processing time depends on video length and your plan. A 10-minute video typically takes 2-5 minutes on Pro plans with priority processing. Free users may experience longer queue times during peak hours. Business plans include dedicated processing resources for faster turnaround.

Yes, Business plan subscribers get full API access to integrate VideoSubtitle into their own workflows, apps, or platforms. Our REST API supports video upload, processing status, clip retrieval, and export management. API documentation is available for registered developers.
