Whats it all about? Achieving the best looking overall pictures around - throughtout the popular GOPs. The great thing about Cluster X developments is you can mix and match some of the settings to combine into your favourite setting (e.g. GOP1 for 24p and 25p/FSH, GOP 6 For 1080i60/30p and 12/15 for 720p etc...). Slipstream settings do this for you (mixed and matched and with spanning capabilities where we can plus 80% modes on H & iA mode support).

This has been a tough (and still ongoing) challenge, each setting (and ptools patch change) takes an age to check & measure. Its exhausting work - even with 4 cameras on the go. The measuring to check Quantisation, frame sizes and stability adapting one change at a time is pretty debilitating on mental energy. I hope people appreciate waiting for each setting to appear.

All the new Cluster X series settings for each GOP attached below have been tested on the notorious 14-140 Pany sharp lens. Give me feedback.

Its as simple as A, B, C, D, E, F ! Each .ini setting in ptools for Cluster X Series will equate to setA ('DREWnet' 12/15 GOP), setB ('Nebula' 6 GOP), setC ('Spizz' 3 GOP), setD ('Moon' 1 GOP/3 GOP), setE (Slipstream 1) & setF (Slipstream 2). Any updates will stay on these sets.

Cluster X 'Slipstream'

A series of GOP combination settings drawn from the Cluster X series but set at nominal bitrate settings (40 to 72Mbps) to achieve a better spanning percentage for longer recordings plus the ability to be used on slower sd cards. Slipstream attempts to correlate the actual clip duration to the TS (transport stream) duration whilst providing error free population of the cpb buffers. And it seems to work very well at these settings. :-)

Slipstream #1 (Rev B): Release Date: 10/03/2013

A mix of Nebula and DREWnet settings all tightly packed into 72Mbps max 24p and around 40-52Mbps for everything else which in my PAL tests SPAN! You also get 80% mode at 24H and iA modes working. NTSC 720p60 and FSH/HBR30p should now span.

1080p24/1080i50/HBR25p/720p50 at GOP 6 1080i60/HBR30p & 720p60 at 12 GOP

Slipstream #2: Release Date: 10/03/2013

Including;-

1080p24H 88Mbps GOP3

FSH1080i50/HBR25p 60Mbps GOP3

720p50 62Mbps GOP6

FSH1080i60/HBR30p 44Mbps GOP12

720p60 52Mbps GOP12

Slipstream #3: Release Date: 15/03/2013

Including THE GH3 MATRIX ON ALL REC MODES;-

1080p24H 150Mbps GOP1 (moon style)

FSH1080i50/HBR25p 70Mbps GOP1

720p50 62Mbps GOP6

FSH1080i60/HBR30p 64Mbps GOP3

720p60 52Mbps GOP12

NB: Ive had one occasion where the camera just freezes with no apparent error. If this happens simply leave the camera alone for a minute or two until it fully writes out to sdcard (emptying all buffers) THEN turn off/battery pull. Hopefully you will notice that all your spanned files are there on next powerup.
