Upload individual image files or a ZIP archive that contains PNG, JPG, WebP, BMP, or TIFF frames. ZIP archives are extracted with 7z, images are discovered recursively, then sorted with natural filename ordering so names like frame1.png, frame2.png, and frame10.png appear in the expected sequence.
Recommended frame naming:
- Use one stable prefix: frame0001.png, frame0002.png, frame_0003.png
- Pad numbers with zeros for large sequences: shotA000001.jpg works better than shotA1.jpg when files are handled by other apps
- Keep the sequence number near the end of the filename: renderscene0100042.png
- Avoid mixing unrelated names such as final.png, copy.png, new.png, because natural sorting cannot infer the intended timeline
- Put only the frames you want to render in the ZIP, or keep extras in clearly named folders that you remove before upload
The tool normalizes frames to a continuous PNG sequence before FFmpeg encoding, which makes mixed image formats and nested ZIP folders safer to process. Optional width and height resize the output; leave both empty to preserve the first frame's dimensions.
