Quicktime "Fast Start" equivalent in Kdenlive?

Hey guys,
Everytime I upload a video to youtube it tells me that my videos will process faster IF I ensure that my video file has "fast start" enabled. I guess it's a quicktime setting when rendering BUT I don't see that option in kdenlive anywhere so is there something similar in kdenlive? I believe it makes the file more compatible for online streaming. It allows the file to be viewed online before it's done completely downloading IF they were to choose to download it. It must put some video information in the front of the file instead of the rear like what's done normally.
My videos still play fine on youtube BUT just wondering if there was anything like that for kdenlive?

not an answer but more informational:

appear to be available as a ffmpeg flag, from the ffmpeg documentation:
‘-movflags faststart’

Run a second pass moving the index (moov atom) to the beginning of the file. This operation can take a while, and will not work in various situations such as fragmented output, thus it is not enabled by default.


and a blog discussing it: http://salman-w.blogspot.com/2013/08/fa ... fmpeg.html


OpenSuse 13.1 x64, KDE 4.12.x

This thread viewtopic.php?f=272&t=116324&p=286973&hilit=faststart#p286973 talks about this.

You create a custom rendering profile by modifying the existing H.264 file rendering profile.

See http://userbase.kde.org/Kdenlive/Manual ... r_Profiles

If this works, then this should be a preinstalled render profile.

BTW I do encode for youtube using kdenlive and the faststart option under the H.264 profile. And youtube still tells me to use fast start. I dunno if this is because youtube says this to everyone every time or because my faststart option has failed. Not sure how to check.
