PNG to MP4

This tool converts a PNG image into a fixed-frame MP4 video by encoding the image as a sequence of frames over the specified duration. Required inputs are the PNG file, duration in seconds, frame rate, and output resolution. Optional parameters include an audio track and an encoding profile. The encoding path uses H.264 inside an MP4 container to maximize compatibility.
Internally, the tool validates inputs (PNG integrity, positive duration, reasonable frame rate) and computes the total frames as duration × frame_rate. It duplicates the PNG for every frame and feeds it to the encoder to produce the MP4. If an audio track is supplied, it is multiplexed into the final file with a standard sample rate.
Target users include video creators, educators, and marketers who need fast, repeatable outputs from still imagery. Unique value includes watermark-free outputs, predictable encoding, and automation-ready options such as API access or CLI wrappers for batch workflows.
Outputs conform to widely supported MP4/H.264 specs and support common resolutions up to 4K; defaults favor speed and broad compatibility. This tool is designed for quick production pipelines, simple asset-to-video tasks, and easy integration into automated media workflows.
