Synectics site and transport recorders. We convert these exports to standard MP4 with a browser-based player, without re-encoding the recorded video.
Multi-camera exports with their own timeline structure, which generic tools either refuse or flatten into a single unusable stream.
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 0 -l 16 "your-file.synav" # macOS / Linux
certutil -dump "your-file.synav" # WindowsA Synectics export begins 53 59 4E 2D 41 56 2D 32 — the ASCII string "SYN-AV-2".
Multi-camera with its own timeline structure, which generic tools either refuse or flatten into a single unusable stream.
Generic tools either refuse the file outright or flatten every camera into one unusable stream.
On this recorder the time in the filenames and the clock burnt into the picture do not agree, and taking one for the other puts every event out by a fixed amount for part of the year. We reconcile them, so the overlay we draw matches the clock already in the image — if those two disagree on screen, the footage invites exactly the challenge you do not want.
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.
Every camera is recovered separately and put back on one timeline, so the views stay in step with each other rather than each starting from zero.
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 →

Synectics site and transport recorders. Multi-camera exports with their own timeline structure, which generic tools either refuse or flatten into a single unusable stream.
Because it is a proprietary Synectics 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: Generic tools either refuse the file outright or flatten every camera into one unusable stream.
As it stands, .synav opens only in Synectics'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 .synav 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.
