HOW IT WORKS
Three steps, no account, nothing to install.
01
Upload your H265 file
Drag in the .h265 file from your camera, NVR or DVR. The recording type is detected from its contents, not its name.
02
Convert to MP4
Start the conversion. The H.265 video is copied into an MP4 and tagged hvc1, and the sound is converted to AAC when needed.
03
Download the MP4
Download one MP4 per file. The video stays H.265, so play it on an Apple device or in a player with HEVC support.
H265
An .h265 file holds H.265 (HEVC) video, usually as a bare stream with no container, or inside a recorder's own framing. Newer IP cameras, NVRs and DVRs use H.265 because it needs much less space than H.264 for the same picture, but most players cannot open the raw file.
MP4
MP4 is the most widely supported video container. With H.265 video tagged hvc1, it plays on iPhone and Mac, in Safari, and in other players with HEVC support. Firefox, older TVs and Windows PCs without HEVC support cannot show the picture.
FILE FORMATS
SOURCE
.h265 holds a raw HEVC elementary stream with no container: the compressed picture only. Newer NVRs, 4K IP cameras, drones and hardware encoders write it. HEVC is roughly twice as efficient as H.264, but a bare stream carries no timing or sound, and many apps can't open it at all.
TARGET
MPEG-4 Part 14 is the default container for phone recordings, web video and streaming. MP4 with H.264 video and AAC sound plays on iPhone and Android, in every browser, on smart TVs and in Windows and Mac players without extra codecs. It holds text subtitles and chapters, but not picture-based subtitles.

USE CASES
Practical workflows where H265 to MP4 conversion is useful.
Watch high-resolution camera footage on iPhone
H.265 cameras record high-resolution video in small files. The MP4 is tagged hvc1, so it plays on iPhone, Mac and in Safari.
Keep the small file size
The video is copied, not re-encoded, so the MP4 stays about as small as the H.265 original instead of growing into a larger H.264 file.
Open IP camera SD card recordings
Cameras that record H.265 to an SD card (HXVT) keep the camera's time for every frame, so pauses play at their real length with the sound in sync.
Check a camera that records at night
SD-card (HXVT) recordings from cameras that drop to a lower frame rate in the dark keep each frame's recorded time in the MP4, so a night clip plays at its real length.
Convert Xiongmai and XMeye recordings
H.265 recordings from Xiongmai-based recorders become a standard MP4, with their G.711 sound turned into AAC.
Play Dahua H.265 files
Dahua DHAV files with H.265 video are copied into an MP4, and AAC sound from the camera is kept as it is.
Show footage to an investigator
The MP4 plays on iPhone and Mac without extra software, so an officer or claims handler with an Apple device can review the clip right away.
Archive footage at its recorded quality
Keep the whole recording, with every frame and the original resolution, in a standard MP4 container instead of a raw stream.
Wrap a raw encoder stream
A raw .h265 stream from a camera's encoder has no container, so players reject it. In an MP4 it opens with the frame rate taken from the stream, or 25 fps when the stream states none.
Rescue a partly copied export
If a copy from the recorder was cut off part-way through, the MP4 starts at the first complete picture, so the rest of the clip is still usable.
SUPPORTED FILES
Recordings from DVRs, NVRs, IP cameras and dashcams are supported.
From NVRs, 4K IP cameras and encoders.
Recorder framing is removed.
Converted the same way.
G.711 and ADPCM sound becomes AAC.
Upload a batch and download the MP4s as a ZIP.
TROUBLESHOOTING
Most problems come from how the recorder exported the clip.
01
Some recorders encrypt exports. Export the clip again with encryption turned off.
02
The export may be empty, all zeros or audio-only. Export the clip again from the recorder.
03
Damaged spots lose frames up to the next key frame. The rest of the recording is kept.
04
CCTV footage often has a variable frame rate, which some editors handle less well. VLC and browsers play it smoothly.
05
Windows needs Microsoft's HEVC Video Extensions. VLC and most browsers play it.
06
A raw stream with no timing plays at 25 fps.
Dahua SmartPlayer, XMeye VMS, Hikvision VSPlayer and similar programs play their own brand's files on Windows. dragdropdo turns H265 into MP4 so the footage plays in ordinary players and editors.
