最新のiPhoneのビデオは、先進機能が詰まっていて確かに綺麗ですが、 「サイズが大きすぎて、PCで扱うには不便。」 「SNSにアップするのも、長時間かかる。」 「リサイズアプリはあるけど、使い方はわからない。」 「はじめからシンプルに、小さいサイズで撮影したい。」 という方にオススメする、データサイズが軽い【ビデオ撮影専用アプリ】です。 ---------------------------------------------------- 撮影モード シンプルに3つ設定のみです。 ①良画質  ビットレート値5Mbps、解像度1080p(10分撮影時約300M) ②普通  ビットレート値1.2Mbps、解像度1080p(10分撮影時約90M) ③超軽量  ビットレート値0.6Mbps、解像度1080p(10分撮影時約75M) -------------------------------------------------------------------------- 《使い方》 1. TanrenCameraアプリを起動し、カメラでビデオ撮影する 2. ボタンで各種設定、機能切替  ・右上に「前後カメラ切替」のスイッチ  ・右下に「設定」でモード設定  ・左下に「カメラロール」へのショートカット 3. 中央の丸ボタンで撮影開始、撮影完了は四角ボタンで終了します

Other strobe photo apps require you to record video inside the app — TrailStack works with footage you already have. Sony MotionShot was discontinued in 2021. Clipstro is iOS-only and cannot import existing videos. Photoshop can achieve similar results, but takes 30–60 minutes of manual work per photo. TrailStack does it in seconds. PRIVACY FIRST All processing happens entirely on your device. We never upload, store, or transmit your photos or videos to any server. What's on your phone stays on your phone. FREE & FAIR TrailStack is free to download and use. Exports include a small watermark. Watch a short optional ad to save a watermark-free version at any time — no subscription, no hidden fees.
