About This Tool
The tool is designed for teams and individuals who need repeatable results in automated pipelines. It supports presets for platform standards, batch-ready input lists for bulk operations, and detailed encoding summaries for integration with asset management systems. It focuses on practical, standards-aligned resizing rather than marketing gloss, providing concrete controls that map to real-world delivery requirements.
In practice, users supply source video, target resolution, and optional encoding settings; the system returns a resized file along with a brief encoding summary and final dimensions. This enables downstream editors, producers, and developers to maintain consistent media quality across projects with minimal manual intervention.
How to Use
- Provide inputs: Upload the source video file and enter target_width and target_height (px). Set maintain_aspect to true to preserve proportions.
- Choose method: select crop_mode (none, crop, or pad) to control how the aspect fit is achieved.
- Configure encoding: pick output_format and optional video_bitrate_kbps, audio_bitrate_kbps, and frame_rate.
- Run processing: initiate the resize task.
- Retrieve results: download output_file and verify final dimensions and bitrate.
