About This Tool

This tool crops a source video to a defined region and re-encodes the result to a chosen format. It supports pixel or percentage-based crop regions and aspect-ratio presets to fit social or broadcast requirements. The processing is server-side, enabling batch operations and consistent output across multiple files. It preserves audio when possible and allows output choices such as MP4 (H.264/AVC), MOV, or WebM, with configurable bitrate and frame rate. Conceptually, the tool maps a user-defined crop rectangle from the input to a new output canvas, then encodes the cropped stream using the selected codec and settings. The result is a cropped clip that preserves the desired framing while offering flexible export options. This benefits video editors, content teams, and automation pipelines that need repeatable, rule-based framing adjustments across large libraries or social campaigns. Unique value lies in combining precise crop control, aspect-ratio targeting, and multiple-output encoding in a single online workflow without bespoke desktop software. Core features include crop by coordinates or presets, aspect-ratio adherence, optional padding, preset or custom output formats, and batch processing readiness. Typical use cases include creating square social videos from long-form footage, preparing vertical clips for mobile platforms, and exporting multiple crops for A/B testing across channels.

How to Use

  1. Provide inputs: upload video or provide URL, specify crop_x, crop_y, crop_w, crop_h or select an aspect_ratio.
  2. Choose output: format and quality (bitrate, fps, etc).
  3. Set crop parameters: define coordinates or use presets to snap to common ratios (1:1, 9:16, 16:
  4. .
  5. Configure outputs: target resolution and encoding options; optional padding if needed.
  6. Run processing: start crop and encode operation on the server.
  7. Retrieve results: download cropped file or access via API in automation.
  8. Validate: review duration, size, and resolution; reuse in workflows.

Frequently Asked Questions

Find Quick Answers

What formats are supported for output?
The tool exports to common containers such as MP4 (H.264/AVC), MOV, and WebM with mainstream codecs. Additional formats may be supported via presets; if a format is unavailable, inputs can be re-encoded to a compatible target.
Can I batch crop multiple videos at once?
Yes. The batch processing mode accepts multiple input items and applies identical crop and encode settings per item. Each output is produced with a corresponding status, enabling automation and parallel work streams.
Does cropping affect audio quality?
Cropping operates on the video stream; the original audio track is preserved when possible. If the source has multiple audio tracks, you may select the primary track to keep. Audio synchronization remains intact.
Are aspect-ratio presets available?
Yes. Presets include common ratios like 1:1, 4:5, 16:9, and 9:16. You can also specify explicit pixel crop dimensions to tailor the output to exact dimensions required by a platform or campaign.
