Don't no whether I'm gonna ruffle any feathers but I was thinking, How about making an Abbreviation Sticky. It seems we are creating a nomencature with these things that any poor new comer may think he just landed on Mars. What do you guys think. I'm gonna jot down a few. But if anyone wants to add anything with its meaning I'll try and collate into some meanigful index when I get the chance.

HD100 - in the context of this forum HD100 generally refers to the JVC GY-HD100U, GY-HD100E, and GY-HD101E
CA- chromatic aberration
PPRO - Adobe Premiere Pro
SSE - Split Screen Effect
FCP - Final Cut Pro
NLE - Non Linear Editor
DV - Digital Video
HD - High Definition
HDV - High Definition Video recorded to MPEG-2 transport stream on mini-DV tape.
SDI - Serial Digital Interface
HD-SDI - High definition - serial digital interface
FA - Focus Assist
AB - Anton Bauer

I know all of these are pretty basic but I would not of known a few months back what some of these were. Feel free to shout me down if you guys think its a bit newbie and dumb. I'm of to the videoforum fair, Earles Court, toady. Exciting.

Thanks Tim,

I just chucked a few down but you're a real workhorse you've made me feel lazy with my effort. You never know it may even make things a bit easier for your good self. I know I'm just as bad but a lot of us do target you and few others for questions that I'm sure you guys must find pretty frustrating sometimes. In particular stuff regarding abbreviations. Anyway hope all is well.

Regards Greg C

P.S. I got my Fs4pro hd 80 gig today so if I get time tomorrow I'll try and rattle of a quick frame or too so you can have a look at the repeat flag thing. Can I just e-mail you a file or will it be to big?

Interestingly, in eastern Europe (Czechoslovakia anyway) acquisition and post were done on PAL equipment and the signal was converted to SECAM at the transmission point. To my knowledge, there isn't much equipment manufactured in the Eastern European SECAM. Yes, the French SECAM is different to the Eastern European version. All of this was done mostly for political reasons during the cold war era. Since most of the early TV sets sold in communist countries were only capable of receiving SECAM, people were unable to watch the 'bad imperialist' western European broadcasting. Today, I believe, most of Europe is PAL all the way.
