When MOV is the right output

MOV is Apple's QuickTime container — the native format for iPhone screen recordings, macOS screen captures, and ProRes-encoded footage. Convert to MOV when your destination is Final Cut Pro, iMovie, or Apple's Motion — these programs handle MOV without transcoding. For distribution, always use MP4 instead.

Convert WTV to MOV without losing quality

Same footage, different container. Get a file that plays where you need it to, with sensible defaults for codec, bitrate, and framerate.

  1. 1

    Upload your WTV file

    Free-tier uploads are capped at 10 MB — fine for short clips and screen recordings, tight for anything long-form. Pro handles files up to 1 GB and batch jobs of up to 20 videos. Because video work is compute-heavy, sign-in is required on the free plan for anything past a minute of source video.

  2. 2

    コーデックと品質プリセットを確認する

    The defaults for MOV are set to the most-compatible codec for that container (H.264 for MP4, VP9 for WebM, and so on). If you want a smaller file at the same quality, pick a modern codec like H.265 — but check where the video's going first, because older devices can't play H.265.

  3. 3

    変換してダウンロード

    Video conversion takes proportionally longer than audio or image work — roughly a few seconds per second of source video on a typical 1080p clip. The output downloads immediately once ready, and both the source and result are deleted from our servers within 30 minutes.

Container versus codec — the difference that matters

A file called WTV tells you almost nothing about what's inside — the container is a box that could hold several different codecs. The codec is what actually determines quality, size, and compatibility. Converting WTV to MOV usually means picking a new codec too; the defaults above are what most people expect to work everywhere.

人が苦労して学ぶこと

  • Every re-encode costs a little quality. If you can get away with just changing the container (a "remux") without touching the codec, the result is bit-for-bit identical and completes in seconds — check the tool page for that option.
  • Don't upscale in a conversion. 720p ソースを 1080p でエクスポートすると、バイトが無駄になるだけです。視覚情報は同じで、アップスケーリングは専用の AI アップスケーラーに属します。
  • 長いクリップで音声がずれる。 Changing framerate significantly (24 → 60) can slowly desync audio. Keep the framerate the same as the source unless you have a specific reason to change.
  • 出荷前にテスト再生を行っております。 まず 1 つの短いクリップを変換し、それを宛先デバイスで開き、動作することがわかったら残りをバッチ処理します。

When WTV to MOV solves a real problem

Six scenarios where the format swap is the actual job — not incidental to something else.

Playing an iPhone clip on Windows or Android

Recent iPhones save videos as MOV wrapped around H.265, which older Windows machines and many web apps can't decode. Converting to a widely-supported MOV makes the clip playable everywhere.

Embedding on a website

HTML5 <video> reliably plays MP4 across every mainstream browser. Some formats (MOV, MKV, unusual containers) trigger downloads instead of playing inline. Converting to MOV first avoids the "why isn't this playing" support thread.

こだわりのあるエディターにフィードする

Final Cut loves MOV/ProRes. Premiere handles most things but chokes on variable-framerate phone MP4s. DaVinci Resolve wants specific codec support. Converting to what your editor actually understands prevents hours of debugging "why is playback laggy".

Getting under an upload size cap

電子メールの添付ファイルの上限は 25 MB です。 Slack の無料プランの上限は 1 GB です。多くの場合、フォーム ポータルは 100 MB 未満を要求します。最新のコーデック交換 (H.264 → H.265) では、通常、同じ品質でサイズが 40 ~ 60% 削減されます。これは通常、解像度に影響を与えることなく制限に適合するのに十分です。

Consolidating a legacy library

Old AVI files, ancient FLV downloads, MPEG-2 rips from a decade ago — legacy formats work but eat disk space. Converting to a modern MOV halves storage without losing quality, and future-proofs the collection against the day players stop shipping with legacy decoders.

Prepping video for platform upload

YouTube, Instagram, TikTok, and LinkedIn all publish their own "recommended encoding" specs. Converting to a spec-matching MOV before upload skips the platform's own re-encode and produces cleaner playback quality.
