How to add SRT and ASS subtitles to videos on iPhone

Downloaded a movie and a separate .srt file? The Videos app on iPhone has no way to load it. Flick does, and in most cases it finds the subtitle file without you doing anything.

The easy way: name the file like the video

Put the subtitle file in the same folder as the video and give it the same name:

VideoSubtitle file
Movie.mkvMovie.srt
Movie.mkvMovie.en.srt, Movie.ms.srt (one per language)
Episode 01.mp4Episode 01.ass

Open the video in Flick and the subtitles are there. Language codes in the name (like .en) help Flick choose the right file.

Supported subtitle formats

Old subtitle files often use a non-Unicode text encoding, which shows up as garbled letters in many players. Flick reads subtitle files in any text encoding.

Fix subtitles that are out of sync

If the words show up too early or too late, open the subtitle options in the player and adjust the delay until speech and text line up. You can also change the text size and background so subtitles stay readable over bright scenes.

Set your languages once

In Flick's Settings, choose your preferred subtitle and audio languages. When a video has several tracks, Flick picks the matching ones for you, every time.

Getting the files onto your iPhone

Copy the video and its subtitle file together, so they stay side by side. From a Mac: connect the iPhone, open it in Finder, go to the Files tab and drag both onto Flick. Or save both to the same folder in the Files app.

Flick – Video Player is free on the App Store for iPhone, iPad and Mac.
