Moov Atom - Sandra - 15.03.2019
Hello,
I'm trying to encode .mp4 files in hevc for browsers.
Apparently that means, that I have to moove the moov atom in the beginning of the files.
Are there any settings in Hybrid that do that?
Thanks,
Sandra

Quote:Interleave/FastStart:source: tool-tip of 'Config->Output->Container Settings->Mp4 Settings->Interleave'.
To prepare a file for HTTP download, the following instruction will interleave file data by chunks of X milliseconds in order to enable playback while downloading the file (HTTP FastStart).
When ffmpeg instead of MP4Box is used, the interleave value can not be set manually.
Side note:
Typically a value of 500 is used for X.

You can also verify it yourself by using AtomicParsley:
AtomicParsley.exe Test.mp4 -TAnd it should show on the second line right after the "ftyp" atom:
E:\Test>AtomicParsley.exe Test.mp4 -T
Atom ftyp @ 0 of size: 24, ends @ 24
Atom moov @ 24 of size: 1127899, ends @ 1127923
Atom mvhd @ 32 of size: 108, ends @ 140
Atom iods @ 140 of size: 21, ends @ 161
Atom trak @ 161 of size: 358098, ends @ 358259
Atom tkhd @ 169 of size: 92, ends @ 261
