I hate when software takes over

This software did help me correct some video sync problems. Unfortunately, though, double-clicking on a saved file causes AV-Sync to open, instead of Quicktime player. I hate it when software does that. It forces me to throw the app in the trash after every use, just so it will stop acting like the default app for all my movie files. Seriously annoying.
It seems that the default app of a file you saved is set AV Sync Fix. Most files have an assigned default app that opens the file when it is double-clicked in the Finder. You can change it for a specific file type. Please try the following to change it to QuickTime Player.
1. Select a saved file in the Finder.
2. Press command + I keys to show the file info window.
3. Choose QuickTime Player in the "Open with:" pop-up button.
4. Click the "Change All..." button if you want to set it for all other same extension files.
AV Sync Fix does not set the default app of files to AV Sync Fix when saving.

Very helpful to losslessly adjust synchronization between video and audio tracks. No need to re-encode. It changes time mapping only. Therefore it runs very fast. However, it takes a lot of space for bigger movies: twice as much as the original file. For smaller files - no problem. Anyway, much quicker and easier than doing the same with the big video editing apps.
AV Sync Fixは、生データの加工（再エンコードやデータ削除）は一切行わず、この再生情報の書き換えで、音声または映像どちらかの再生開始のタイミングを調整して音ズレを修正します。動画プレーヤーはこれらの再生情報に基づき動画を再生します。一度修正した動画を再度AV Sync Fixで元の数値に戻せば元の状態に戻ります。
再生情報は、MOV、MP4系ファイルコンテナフォーマットの仕様に準拠してますが、動画関連アプリがこれらの再生情報を再現させるかはアプリ次第で、ご使用の動画カットアプリが再生情報をどのように認識しているかではないでしょうか。先に不要部分を削除してから音ズレを修正をしてみてはどうでしょうか。

Works great once you figure it out

No documentation to speak of and so figuring out how to use it can take a bit of time. I tried a couple of things and one of them worked and voila - my video was fixed. Would be five stars with proper documentation.
In my case I saw the audio and video tracks had different lengths - I subbtracted these and set the audio to start at the difference, and that did the trick.
映像が早ければ映像のスタートを遅らせ、音声が早ければ音声のスタートを遅らせて合わせるという、映像と音声のズレを修正する面で非常にシンプルで使い易いソフトです。データの読み込み時間もそれほど遅くは感じませんでしたし、読み込みによって最後の保存に時間がかからないのも良いです。幾つかデータを修正しましたが、今の所は問題なしです。今後対応フォーマットが増えることを期待しています。使用環境：MacBook Pro (13-inch, Mid 2010) OSX10.11

A simple application that does exactly what it claims: it’s elegant, uncluttered and effective, without requiring recoding of videos.
Some preference settings would be useful, however, such as a larger default size for the video image, which is currently shown at its actual size. The application also puts up an ‘unplayable track' warning if the video contains an AC-3 track, which really isn’t necessary.
Quibbles aside, first rate!

This app immediately crashes when trying to use it on 10.10.3. Author seems to be aware of it. Hopefully update will work… Otherwise money down the drain.
Fixed this issue in v1.2

MOV、MP4系ファイルコンテナは音声、映像、字幕、チャプタマーカーなどの生データの他に、それらのデータをどの部分から、どれだけの長さを、どれだけのスピードで再生させるかという、再生情報が記録されています。 「1分から1分30秒を2回繰り返して、2回目は半分のスピードで再生」とか、「1分から2分を再生したあと、先頭に戻り再生」などの複雑な再生情報を音声、映像それぞれのトラック毎に記録できます。（AV Sync Fixではこのような編集はきません）

一見するとよくわかない箇所はありますが、すぐにどこを触れば編集できるのか理解できます。
とても細かく編集でき大満足です。
