Fix MP4 & MOV files that won't play
Your camera lost power before it finished writing the file. Every frame you recorded is still in there — what is missing is the index. Video Repair rebuilds it, on your phone.

It is almost never the footage that broke.
Video data goes into the file continuously while you are filming — frame after frame, straight to storage.
A small table that tells a player where each frame starts is only written when recording stops normally. A flat battery, a crash or a pulled card means it is never written at all.
Without that table, nothing can find the first frame — even though the footage is sitting untouched inside the file. Video Repair reads the raw data and rebuilds the table around it.
Six things, and it is honest about all of them.
It reads the file and tells you what is actually wrong before touching anything — a missing index, a truncated tail, or media data that really is gone.
Every frame boundary is found in the raw bitstream and a fresh, valid index is written around your original data.
You play the recovered footage inside the app, on your own screen, before deciding whether it was worth anything.
The whole repair runs on the phone. No upload, no server, no account, no sign-in.
The recovered video is your camera's own compressed data, copied through byte for byte. No second round of compression, so no quality loss.
Add any healthy clip from the same camera and the sound track comes back with the picture. The app says up front whether yours needs one.
One fault, many ways of hitting it.
Said here rather than after you install it.
The footage you are trying to save is often the footage you would least want uploaded.

You watch your own footage play again before paying anything. A single one-time purchase unlocks saving the repaired file — no subscription. If the recovery is poor, you have lost nothing. Payment is handled securely through Google Play Billing.
Short answers, no hedging.
An MP4 or MOV file is written in two parts: the video data as it is recorded, and a small index at the end that tells a player where every frame starts. The index is written last, when recording stops normally. If the camera loses power first, the index is never written — so every player reports a corrupt file even though the footage is intact.
No. Video Repair fixes files that exist but will not open. It is not an undelete tool and does not scan storage for lost files.
No. The whole repair runs on your phone. There is no server to send the file to, and no account to create.
Usually not for the picture. Most cameras repeat their encoding parameters inside the footage itself, so the video is rebuilt from the damaged file alone. Sound is the exception: to recover the audio track you add any other clip recorded by the same camera that plays normally. The app tells you which case you are in before it starts.
No. Nothing is re-encoded. The recovered video is your camera's own compressed data, copied through byte for byte, so no second round of compression happens.
MP4 and MOV containers carrying H.264 or H.265 video — which covers phones, dashcams, drones and action cameras. H.265 repair currently needs a healthy reference clip from the same camera.
Nothing. It is read, never written to. The repair is written as a new file, so if the result is not good enough you still have exactly what you started with.
