Comment (by troy_s):

 On advice of michaelni, using the scale option to set range and color
 coefficients is not updating the flags in the stream:

 {{{
 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from './out709-full.mp4':
   Metadata:
     major_brand     : isom
     minor_version   : 512
     compatible_brands: isomiso2avc1mp41
     encoder         : Lavf55.48.101
   Duration: 00:00:03.00, start: 0.000000, bitrate: 168 kb/s
     Stream #0:0(und): Video: h264 (High 4:4:4 Predictive) (avc1 /
 0x31637661), yuv444p, 1920x1080 [SAR 1:1 DAR 16:9], 163 kb/s, 25 fps, 25
 tbr, 12800 tbn, 50 tbc (default)
     Metadata:
       handler_name    : VideoHandler
 }}}

 Setting the flags manually via -colorspace bt709 and -color_range jpeg
 results in the correct flags being set in the stream:
 {{{
 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from './out709-full.mp4':
   Metadata:
     major_brand     : isom

   Duration: 00:00:03.00, start: 0.000000, bitrate: 168 kb/s
