Recommended settings for HF S100

Dokument v českém jazyce naleznete zde…
This is my recommended settings for CANON Legria HF S100
Manual setting (Tv or Av)
Keep f between 1.8 – 5.4 (higher values makes picture blurrier),
exposure between 25 (30 USA) – 500 (higher values makes visible rolling shutter problem)
f=4 and exposure 1/50 (1/60) is the best sollution :-)

Colors: normal, Sharpness: low, Contrast: low (maybe medium), Brightness: high (maybe medium)

Limit gain control (AGC Limit) to 6dB
(bigger values makes picture noisy 6dB is OK in dark scenes)
x.v.Color ON (for better gamut)

1920x1080x25p or 30p (USA) (1440×1080 isn’t recommended due to 4:2:0 color-subsampling)
Bitrate 24Mbit/s (AVCHD – not high-enough for water etc :-) but still 2x better than HDV at 25Mbit/s)

Switch Onscreen (Grid, Zebra, Audio Level)
Be sure to import video as progressive (not interlaced),
in Sony Vegas you can find it in every imported clip properties
(field order -> progressive scan) don’t forget it!!!
set output project to progressive and exact framerate 25fps (30 USA)!!!
video pixel format 32bit (full-range)

Strictly use lossless compression such as HUFFYUV, Lagarith or MSU.
For final export I recomended H264 2pass.

Simple-REST application for searching

Jan programmed easy rest server application which emulates ArcGIS REST-JSON interface and search point-layer very, very quickly. :-)
About 3 milions street names with numbers within 0.001 second per query. There is a posibility to speedup searching a lot below this time.
Nearly unlimited users can use this service :-) because clustering is easy.

Content Delivery Network

Today i was testing simple content delivery network (CDN). it’s implemented on high-level in application layer and uses reverse proxy (with temporary storage). Network ranges are cached in main database and selected while request is being processed.
Schema is very easy and there’s no exact limitation about number of users and nodes.
