The scene was simple: a paper airplane on a desk near an open window. The curtain moves a little, and the airplane lifts from the desk toward the window.

I knew what I wanted at the start. I just couldn't decide where to stop.

In one version, the airplane was already outside the window. In another, it was still crossing the frame, with part of it inside the room.

I kept switching between the two.

Showing the airplane outside made the action feel finished to me. Ending a little earlier left more of the moment hanging, which I also liked.

I had both versions sitting in Vidu Q3 and probably watched them more times than necessary.

At one point I moved the ending later again, watched it, then changed it back.

There wasn't anything obviously wrong with either version. I just preferred different things about them.

For now, I've kept the earlier ending in the draft.

The other version is still saved, though. I may look at both again tomorrow and change my mind.

It had a cup being placed on the table, someone opening a book, a wider shot of the window, and a few people moving in the background.

I'd watched the edit enough times that I barely noticed the cuts anymore. Once I added the music, though, two of them started to bother me.

The first landed during a quieter part of the track and felt a little early. A few seconds later, another cut made the next shot feel rushed.

My first thought was to change the music.

I tried another track, listened to about half of it, then switched back to the first one. Neither felt obviously wrong, so I stopped looking for another track.

The first one was something I'd been working with in Suno v6, but before replacing it, I went back to the timeline and moved those two cuts slightly.

I didn't rebuild anything. One shot stayed on screen a little longer, and the next one came in later.

When I watched it again, I preferred the new timing.

I still wouldn't call it completely finished. I'll probably listen once more before deciding which export to keep.

Both versions are still in the same folder with almost identical filenames.

I should probably fix that too.

小さな教室の連絡なら、変更のお知らせで知りたいのは「結局、何時に行けばいいの？」ということ。長いあいさつより、変わった点を先に伝えたほうが分かりやすそうです。

私が運営する Index TTS で案内を音声にする場合も、まず変更後の原稿を確定させます。声の調整は、そのあとです。

変更のお知らせは、一文目から

たとえば、架空の手芸教室なら。

「9月20日の手芸教室は、集合時間が午前10時半に変わりました。場所は前回の案内どおり、1階の受付です。」

「時間が変更になりました」だけでは、前の案内を探すことになります。新しい時刻まで入れれば、この連絡だけで確認できます。

「明日」より日付を入れておくと、あとから再生したときも、いつの話か分かります。

古い音声を残したままにしない

送信済みの音声は、相手が保存していることもあります。新しい音声を送るだけでなく、「前の案内ではなく、こちらをご確認ください」と文章も添えておきます。

ブログに古い音声を載せているなら、差し替えるか、すぐ近くに訂正を表示。ファイル名にも日付と「更新版」を入れておくと、自分が送り間違えるのも防ぎやすくなります。

送る前に、時刻をもう一度

完成した音声は、日付・時刻・場所を原稿と照らし合わせて聞きます。参考音声には、自分の声か利用許可を得た声を使ってください。

最後に、文字の案内も同じ内容になっているか確認。参加する人が古い連絡を開いても、どこを見れば最新の予定が分かるか。それがはっきりしていれば、出かける前に迷わず済みます。
