With Original Quality, Trymmer copies your video without re-encoding it. A copied video can only start on a keyframe, a complete picture that the following frames are built from, so each kept part starts at the keyframe just before your mark. Phone videos usually have one every second or two. The timeline shows the adjusted start.

To cut on the exact frame, turn on Exact cuts in the export sheet. Trymmer then re-encodes only the few frames at each cut and still copies the rest untouched. Choosing a preset such as HEVC High Quality also cuts exactly, but re-encodes the whole video.

Exact cuts works with H.264 and HEVC videos, which covers almost all phone and camera recordings. The export sheet says why it isn't available. The usual reasons are another codec, a crop (which always re-encodes), several videos joined into one timeline, or a file whose format changes partway through.

MP4, MOV, and M4V files that your Mac or iPad can play. That includes videos from iPhone, most cameras, screen recordings, and most downloaded videos. Formats like MKV, AVI, and WebM aren't supported.

For your security, macOS only gives an app access to the video you opened, not to the folder it's in. The first time Trymmer saves next to a video, it asks you to allow that folder. It remembers the permission, including for other videos in the same folder and its subfolders. You can also choose a fixed output folder in Settings.

Videos opened from Files are saved next to the original when the location allows it; otherwise Trymmer asks where to save. Videos chosen from Photos are saved to the Files app under On My iPad › Trymmer, and to your photo library when Save to Photos is on (it's on by default for those videos). Finished exports in the queue also have a Share button.

Original Quality exports copy the video and are very fast. Exports that use a preset, crop the video, use Fit to Size, or normalize the audio have to re-encode every frame, which takes longer and depends on your device. The export queue shows the time left, and you can keep editing while it works.

Yes. Trymmer asks first, then pauses the export. Next time you open Trymmer the export is waiting in the queue, paused. Press Resume and it continues from where it stopped instead of starting over.

Never. Trymmer always writes a new file and doesn't modify the original. If a file with the same name already exists, it adds a number instead of replacing it.

No. Everything happens on your device, and Trymmer doesn't collect any data. See the privacy policy.
