How does ConvertHub make high-quality animated GIFs from video clips?

We utilize a specialized two-pass FFmpeg palette generation filter (palettegen + paletteuse with Lanczos scaling and Bayer dithering). This samples the exact 256 optimal colors from your video frames, eliminating the pixelated noise and banding common in standard GIF converters.

Will converting MOV or WebM to MP4 cause audio and video desynchronization?

No. Our FFmpeg transcode pipeline enforces strict timestamp alignment (-pix_fmt yuv420p, fixed frame rates, and synced AAC audio tracks) to guarantee perfect audio-video synchronization.

What is the maximum file size I can convert for free?

ConvertHub allows free media conversions for files up to 100 MB without registration, watermarks, or credit card requirements.
