### 1/5 — Не работает

*2026-04-09*

Приложение не работает. Выбираю 4k файл на 500 мб и выбираю сжать его до 720p с низким качеством. Приложение обещает 20 мб. Жду обработку и после этого получаю файл 4k на 250 мб. Это не то, что я хотел получить. Разрешение не изменилось. 

Так же есть только кнопка «обработать и удалить оригинал». А я не хочу его удалять, я хочу сравнить. 

Даже нет триал версии, из-за чего я просто впустую потратил деньги на приложение.

**Developer response:** Здравствуйте! Вы были абсолютно правы, и спасибо, что подробно описали проблему. Причина найдена: iPhone снимает 4K в HDR, а приложение не меняло разрешение у HDR-видео — поэтому вы получили 250 МБ в 4K вместо обещанных ~20 МБ в 720p. В версии 1.1 это исправлено: HDR-видео сжимаются точно до выбранного разрешения, а оценка размера теперь рассчитывается по фрагменту вашего реального видео и совпадает с результатом. Также добавили то, о чём вы просили: можно отключить удаление оригинала, сравнить оба видео рядом на новом экране результата и удалить оригинал позже одним нажатием. Пожалуйста, обновитесь и попробуйте ещё раз. Если хотите вернуть деньги за неудачный опыт — это можно сделать через Apple на reportaproblem.apple.com. Будем благодарны, если после обновления вы пересмотрите оценку.

## Version history (last 5 releases)

### 1.1 — 2026-08-03

iPhones record 4K video in HDR by default, and compressing those videos previously left the resolution unchanged — so “720p” could still come out as a huge 4K file. That’s fixed: HDR videos now scale to exactly the resolution you choose, keeping their HDR brightness and colors.
Also new:
- Keep the original - turn off “Delete original after compression” to compare before deciding
- Compare screen - after compressing, see before/after size and resolution, and play both videos side by side. Delete the original with one tap when you’re happy
- Honest size estimates - we now compress a short sample of your actual video to predict the final size, instead of guessing
- Every setting is real - bitrate quality, HEVC/H.264, and frame rate (24/30/60 fps) are all genuinely applied now
- Preserve HDR toggle - keep HDR, or convert to standard colors for an even smaller file
- HDR badges and filters - spot 4K, HDR, Slow-Mo, and Timelapse videos in your list
- Siri & Shortcuts - say “Compress my latest video in Klin”
- Clear guidance on emptying Recently Deleted so your freed space actually shows up
If compression ever disappointed you before this fix - we’d love for you to give it another try.

### 1.0.4 — 2026-04-04

Polished things under the hood for a cleaner, snappier experience.
