CalcLockAt a glance: A Live Photo is more than its cover frame. Check motion, sound, and the chosen still separately; a visible thumbnail does not confirm preservation of all three.
Name the part you care about
A photograph of someone laughing may matter because of the movement and voice around the shutter moment. Another Live Photo may be useful only for its best still frame. Decide which you need before importing. Otherwise it is easy to approve a sharp preview and discover much later that the part you valued is missing.
Make a three-item checklist: the still appearance, the moving sequence, and the audio. Add any effect you deliberately applied, such as a loop. A format label alone cannot tell you whether a particular app preserves or plays each part.
Build a harmless test set
Choose a Live Photo with obvious movement and audible sound, plus one you have edited. In Photos, play each source and note the start and end of the action. Check that audio is actually present rather than assuming silence comes from the destination app. Review any mute or Live-off setting on the source.
Apple documents controls for the key photo, trimming, sound, and effects. These are Photos features. Their availability in the source library is not evidence that the same editing controls will exist inside CalcLock or that its import carries the editing history.
Test the imported result in three passes
Import only the sample into the intended CalcLock vault. First compare the still frame and orientation. Then try the playback behavior available in the app and see whether the expected movement appears. Finally listen privately with an appropriate volume and compare the audio. Avoid playing personal recordings through speakers where others can hear them.
If the result is a still image, record that as the actual behavior of your test. Do not reinterpret a successful import message as proof of Live Photo support. Keep the full original in Photos or another suitable source archive.
Use a separate video when the motion matters
Apple provides a Save as Video option for a Live Photo in Photos. That can be useful when your goal is a conventional moving clip rather than the full Live Photo editing experience. Create a test video from the source and inspect it before importing it as a video into CalcLock.
The resulting video is another version, not a replacement for every capability of the original. Check its sound, duration, and framing. Keep track of which file is the still, which is the video derivative, and which remains the original Live Photo so later cleanup does not remove the wrong item.
Preserve the version you cannot recreate
CalcLock has no export, backup, restore, synchronization, or recovery for a forgotten equation. Even an imported clip that plays correctly should not become your only copy of a meaningful moment. Store the source where you can retrieve it independently of this phone and its local vault.
Repeat a small format test after a change to your capture or import workflow. You do not need to inspect every frame of a large collection, but you should sample each kind of material you rely on. A quick test with one still image says little about a library full of Live Photos.
Questions, answered
Does a working thumbnail prove the Live Photo is complete?
No. A thumbnail can represent only the still frame. Check motion and sound explicitly, and keep the original regardless because CalcLock does not provide an export or restore path.
