Frequently Asked Questions

Yes. Most Chinese DVRs (Xiongmai, HiSilicon and white-label rebrands) wrap MPEG‐PS in a proprietary header starting with the bytes IMKH. CCTV Converter detects that signature and converts to MP4 with no quality loss in seconds.

Dahua DHAV files convert directly. Hikvision is more varied — standard H.264 backups work fine; encrypted backups (.crypt) cannot be decrypted by any third-party tool and need Hikvision's own player.

Yes. The default conversion is a stream copy, meaning the video and audio packets are repackaged into MP4 without being decoded or re-encoded. The output is bit-identical in quality to the source. Re-encoding only happens as a fallback if the original stream is incompatible with MP4, and it uses high-quality H.264.

Yes — tick “Add timestamp overlay to converted video” in the options panel before you convert. A date/time clock taken from each file’s recording time is burned into the bottom-left of the MP4, incrementing per frame. Required by most insurance companies and accepted as evidence by courts in many jurisdictions. (See our Terms on relying on output as a sole legal record.)

Yes. The built-in editor lets you trim to the exact frame, crop, rotate, and adjust brightness, contrast, saturation and sharpness, reduce night-time grain, and set the output resolution and quality. You can save your settings as presets. Edits always export to a new MP4 — your original files are never modified.

Yes — the Multi-Camera view plays up to six recordings side by side on a single timeline, with per-camera offset nudging so you can line up clocks that have drifted apart. Snapshot every angle at once, build a contact sheet, or export a synchronized composite video.

Point the app at your footage and it scans for movement, then exports just the clips where something happens — with adjustable sensitivity and pre/post-roll padding so you keep the run-up and run-out of each event. Save each event separately or as one combined highlight reel, and skip hours of an empty driveway.

Around 200× realtime for a typical CCTV bitrate. A 30-second clip converts in well under a second. With parallel conversion enabled (up to 8 files at once), a full day of recordings — a few hundred clips — takes well under a minute on a normal laptop. Optional GPU acceleration (NVIDIA / Intel / AMD) speeds up re-encodes. Stop and resume any time.

16 languages: English, Indonesian (Bahasa Indonesia), Vietnamese (Tiếng Việt), Thai, Filipino, Chinese (Simplified), Japanese, Korean, Spanish, Portuguese (Brazil), French, German, Russian, Turkish, Ukrainian and Arabic (right-to-left). The app auto-detects your Windows language on first launch and you can switch any time from the globe icon in the toolbar.

Yes. CCTV Converter does its work entirely on your machine and never uploads your footage. Once installed you can disconnect from the internet and it keeps working — the only optional network use is checking for an update when you ask it to.

Windows 10 or Windows 11, x64. The Microsoft Store version is self-contained — it bundles the .NET runtime and ffmpeg, so there are no prerequisites to install and no admin rights are needed for normal use.

Because the niche is small and we'd rather you have a tool that solves the problem than nothing. If it saves you a headache, you can buy us a coffee — otherwise, just enjoy the app.
