Question: Is 'Web Optimized' enabled by default in CLI?

I forgot to append --optimize (but also didn't append --no-optimize) when using the current CLI version and did not use any preset.
So I wonder, what is the default behaviour then?

Depends on what preset you use. Presets intended for web delivery or streaming have this enabled by default.

I did not use a preset:

Command I've used:
Code: Select all
HandBrakeCLI.exe --input "raw.mkv" --output "rendered.mp4" --audio-lang-list "und" --native-language "deu" --all-audio --quality 19 --rate 30 --pfr --ab 320 --encoder nvenc_h264 --width 1920 --height 1080 --crop 0:0:0:0
I now see that the default preset which is used will be the preset with the name
CLI Default. Optimization seems to be disabled because
Mp4Optimize is set to
false.
I've checked the MP4 file and it seems, the MOOV atom is - as expected - not positioned at the beginning:
Code: Select all
root:~# qtfaststart -l video.mp4
ftyp (32 bytes)
mdat (4445064076 bytes)
moov (13214296 bytes)
However, Google Chrome and Mozilla Firefox are able to play a MP4 with 4 GB at any position without any problem which is quite interesting because in the past they were not able to do that. Does anyone know why is that?

Because if your web server supports it, HTTP allows your browser to request any byte range. So it asks for the end if the file first to figure things out.

Is that only with HTML5 ?

Not related to HTML. HTTP 1.1 supports it, just need the web server software to support it and be enabled.
