Hi

Do you know Where is the video length information in mp4(h.264) file?

How can I get that?

Hard to find that cause the search words are so simple.

Thank you

In what way ? Most of the time, this is stored in the moov->mvhd atom...in fact, you need duration & timescale.

If you don't care about that, have a look at MediaInfo to retrieve some infos about your file.

I gotcha thank you Kurtnoise13

ReadAtom: type = "mvhd" data-size = 100 (0x64) hdr 8
Read: version = 0 (0x00)
Read: flags = 0 (0x000000)
Read: creationTime = 2082844800 (0x7c25b080)
Read: modificationTime = 2082844800 (0x7c25b080)
Read: timeScale = 1000 (0x000003e8)
Read: duration = 2143 (0x0000085f)
Read: rate = 1.000000
Read: volume = 1.000000
Read: reserved1 = <70 bytes>

For what for ? I don't get your point...

btw, Any hex editors or Dumpster should be able to do that.
