ADPRO and Xtralis site recorders. We convert these exports to standard MP4 with a browser-based player, without re-encoding the recorded video.
Each camera arrives as its own file with its own start time, so playing them together means guessing at the offsets.
The usual result is that the footage exists, is perfectly good, and cannot be watched by the person who needs to watch it — because the only software that opens it is the manufacturer's own, it is Windows-only, and the machine it needs to run on is locked down.
Extensions get reused and renamed, so the reliable test is the first few bytes of the file. On any machine, without installing anything:
xxd -s 16 -l 16 "your-file.hbox" # macOS / Linux
certutil -dump "your-file.hbox" # WindowsA ADPRO / Xtralis export begins 63 30 30 30 32 at offset 16 — the ASCII string "c0002" at offset 16 — the file opens with a 0x84 metadata record whose five-byte payload is the version string.
One .hbox per camera, each already Annex-B, with the recording times carried in the filenames rather than inside the data.
Each camera starts from zero, so playing two together means guessing the offset between them.
Each camera starts independently, so the offsets between them are computed and applied to put every view on one timeline instead of each starting from zero.
Read by own parser. ffmpeg cannot open this container at all, which is why the ordinary tools a customer already has produce nothing from it. We read it ourselves. The source-side integrity digest is therefore taken from the extracted stream, since that is the only point at which the original picture data can be measured.
Cameras are resynchronised against the recorder's own clock so they play together properly rather than approximately.
The coded video itself is copied, never re-encoded. That is the point: what you receive is the recorded image, not a compressed copy of it.
One standard MP4 per camera, a browser player with every camera on a shared timeline, and a certificate digesting the coded picture data before and after — which match, because the video is copied rather than re-encoded. What every conversion includes → · How the check works →

ADPRO and Xtralis site recorders. Each camera arrives as its own file with its own start time, so playing them together means guessing at the offsets.
Because it is a proprietary ADPRO / Xtralis format. General-purpose players such as VLC, Windows Media Player and QuickTime are not built to read it and usually show nothing or refuse the file. In practice: Each camera starts from zero, so playing two together means guessing the offset between them.
As it stands, .hbox opens only in ADPRO / Xtralis's own player, which is Windows-only and often has to run on a locked-down machine. The dependable way to open it anywhere — any operating system, no install — is to convert it to MP4, which is what we do. The recorded video is copied, not re-encoded, so what you watch is the recorded image itself.
Send us the .hbox export — ideally the whole folder as the recorder wrote it. We convert it to standard MP4, one file per camera, with a browser player and a certificate that digests the coded picture before and after so the result can be verified independently. The first conversion is free. If it turns out not to convert, we may ask for the player it shipped with so we can make it work.
