Frequently Asked Questions
What is a .h264 (or .264) file?
It's a raw H.264 'elementary stream' — just the encoded video frames, with no container, no index, and no timestamps. Cameras, hardware encoders, IP-camera exports, and embedded systems often output this raw form instead of a full MP4.
Why won't my .h264 file play?
Players need a container like MP4 that describes the stream — its duration, frame timing, and how to seek. A raw .h264 has none of that, so most players either refuse it or play it with no seeking and the wrong speed. Wrapping it in MP4 fixes this.
Is .264 the same as .h264?
Yes. .264, .h264, and sometimes .avc are all common extensions for a raw H.264 stream. FileHop treats them identically and converts them the same way.
Does converting re-encode the video and lose quality?
No. The H.264 stream is already in exactly the codec MP4 uses, so FileHop copies it directly into the MP4 container — a 'stream copy'. There is zero quality loss and it's almost instant, no matter how large the file is.
Where do raw .h264 files come from?
IP camera and CCTV exports, standalone hardware encoders, drones and action cams in debug or raw modes, GStreamer/FFmpeg pipelines, and embedded or automotive recorders all frequently dump a raw H.264 stream.
My .h264 plays at the wrong speed or shows no duration. Will MP4 fix that?
Yes. Raw streams carry no timing information, so players have to guess the frame rate. Wrapping the stream into MP4 assigns proper timestamps, so duration, playback speed, and seeking all work correctly.
Can I batch convert many .h264 files at once?
Yes. Drop a whole folder of .h264 or .264 files into FileHop and convert them all to MP4 in one go. There is no file limit.
Does a raw .h264 file include audio?
Usually not — an elementary stream is video only. If you have a separate audio file, you can add it after converting using FileHop's video editor.
Will the MP4 play on phones, browsers, and editors?
Yes. H.264 in an MP4 container is the universal video standard. It plays on iPhone and Android, Windows and Mac, every browser, and imports cleanly into any video editor.
Is this different from transcoding?
Yes, and it's better for this job. Transcoding re-encodes the video, which is slower and loses a little quality. FileHop simply re-wraps the existing stream into MP4, so it's faster and completely lossless.
