Frequently Asked Questions
How does in-browser video cropping work without uploading my video?
Our video cropper runs WebAssembly-compiled FFmpeg directly inside your web browser. The video frames are decoded, cropped according to your exact pixel coordinates or aspect ratio, and re-encoded in your local device memory. No video footage is ever uploaded to external servers or cloud storage.
What is the best aspect ratio for TikTok, Instagram Reels, and YouTube Shorts?
The optimal aspect ratio for vertical social video is 9:16 (typically 1080x1920 pixels). Clicking the 9:16 preset button locks the crop frame to this exact vertical ratio so your video fills mobile screens seamlessly with no black letterbox bars.
Will cropping my video reduce its quality or resolution?
Cropping removes pixels outside your selected frame, so the output resolution matches the crop box dimensions. To prevent quality loss, our engine uses high-fidelity H.264 encoding with balanced bitrates and Lanczos scaling, keeping the remaining image crisp, sharp, and artifact-free.
Can I crop videos recorded in horizontal 16:9 into vertical 9:16?
Yes. Simply click the 9:16 button, then drag the crop box horizontally over the video preview to center your subject (such as a speaker, athlete, or gameplay highlight). The engine will export a clean vertical video formatted for mobile viewing.
Are there any watermarks, file size limits, or subscriptions required?
No. Unlike other online video editors that place large watermarks across your video or limit you to 60-second clips, Agenda Creativa is 100% free with unlimited crops, no watermarks, and no sign-ups required.
