video to GIFは何に適していますか?
Video to GIF captures a short segment from the selected time and generates a GIF with ffmpeg.wasm in the browser. GIF is useful for short looping previews, but it can be much larger than an equivalent video clip.
The first version defaults to short durations and moderate width to reduce browser memory pressure. Keep the source file before processing important media.
サポートされている形式: MP4, MOV, WebM, AVI;単一ファイルの制限: 500MB。

よくある質問
Why is the GIF file large?
GIF compression is inefficient. Longer, wider, or more dynamic clips produce larger files.
How long should the clip be?
Use short clips of a few seconds. Longer clips may be slow or memory-heavy.
Will the video be uploaded?
No. The GIF is generated locally in the browser.
