MPEG 至 TIFF 变 变 常 数

How do I extract frames from a MPEG video as TIFF images?
+
Upload the MPEG file and the converter exposes a frame-extraction picker: every Nth frame, frames at specific timestamps, or one frame per second. Each chosen frame is encoded as a separate TIFF file and bundled as a ZIP for download.
Same resolution as the MPEG video — a 1080p source produces 1920×1080 TIFF frames; a 4K source produces 3840×2160 TIFF frames. Resize after extraction if you need smaller thumbnails.
Yes, but be careful with file count — a 30fps 1-minute video produces 1,800 frames. We pack them into a ZIP archive automatically. For longer clips use the "1 per second" option (60 frames) or specific timestamps.
Yes — colour is decoded with the same matrix the source MPEG uses (BT.709 for HD, BT.2020 for 4K HDR). HDR sources are tone-mapped to SDR when extracting to TIFF (PNG / JPG can't store HDR pixel ranges natively).
Depends on resolution and codec choice. A 1080p PNG frame is 2-5 MB; a 1080p JPG quality-85 frame is 200-500 KB. Multiply by frame count to size the ZIP — at the extreme, every-frame extraction of a 10-min 1080p video at PNG is ~50 GB.
The MPEG container does not store per-frame EXIF the way a still camera does, so the TIFF files come out with empty EXIF. We embed a `creation_time` field pointing at the source frame timestamp so you can re-sort the bundle.
Frame extraction is fast — typically 20-30% of source duration on the standard pipeline. A 5-minute MPEG → TIFF bundle finishes in about 1 minute regardless of frame count, because the bottleneck is the TIFF encoder, not the demuxer.
Yes — the advanced option accepts a comma-separated list of timestamps (e.g. `00:01:23,00:05:00,00:10:42`) and produces one TIFF file per timestamp. Useful for chapter thumbnails or scene reference shots.
Yes — same privacy model as every conversion. Source video and extracted frames are processed in isolated workers and deleted within minutes.
Almost always motion blur from the source MPEG (the camera was moving when the frame was captured). Try picking timestamps from static scenes, or extract several adjacent frames and choose the sharpest. The pipeline does not synthesize sharpness.
Not in the basic flow — use the "1 per second" option as an approximation, then visually pick scene-change frames. A dedicated scene-detection extractor is on the roadmap.
Yes, subject to whatever licence governs the source MPEG content. The format change adds no claim — we add no watermark and claim no licence on the TIFF output.

MPEG

MPEG is a popular file format.

TIFF

TIFF 文件支持高位深度和无损压缩,是专业摄影和印刷的理想选择。
