well
you deliver in 29,97 FPS while the UK is a 25 FPS country.
they have to do framerate conversion.
maybe it is wise to do the framerate conversion yourself and check before delivery.
framerate can give lipsync issue’s when done badly.
indeed checking lipsync on a CRT is good practise. what you put in a CRT come’s out almost immediately.greet

well at first.
in the industrie we often don’t call things by there name.(bad habit)
the snell is actually a framesycroniser which is more then a TBC.
a TBC is in general a device that stabelize the unstable output of a vtr in the earlier day’s this was a seperate unit now aday’s it’s implemented in the deck. a tbc in it’s most native form cannot syncronise a signal it can only stabelize it. your snell can frame syncronize a signal that’s why it was sold seperate. it was mostly used to syncronize remotefeeds to studio ref.again don’t use composite if you want to use the snell use the dub connection.
bob often cried out loud to me that it is impossible to explain adjustments on decks on a forum although i tried.
please find your self a local expert to service your deck he will be worth the money.greet

hi there
still no progress.
have replaced some hoses which isn’t that simple as it sounds.
there are 4 pressure control’s the 2 on the bottom and the one on the left give a reaction on the meters but the one on the right gives no reaction. i can’t feel air coming out of the tapeguides on the scanner do you guy’s have a practical way to check ???
can there also be an electrical cause for high capstan current.greet

#1 – throw out the VPR3.
you won’t believe this but the deck is used weekly and urning money big time.
my boss will kill me if i throw it out. people want to have there old crap digital before it get’s impossible.#2 – well your a experienced guy so the carbon brushes is a thing that i will check.
but i don’t understand what this has to do with the capstan. what the warning is saying to me is that the capstan is having a hard time pulling the tape through the transport. what has this to do with the scanner assembly ? of coarse the tape is laying around it and the scanner is giving friction. but if the RPM of the
scanner is wrong comparing to tape speed i would have error’s in the picture. this is not the case. the deck is operational.
can you explain i guess i’m missing something.greet

hi
hooking up Ref is alway’s a wise thing to do.
you can use a other stable videosource for that if you don’t have BB.
if you want things sharp don’t think about composite use component.
let an expert look at your machine bluriness can come from several misalingment’s a bit hard tell. it is always wise to let your machine checked once and a while. it’s analog so it will become out of spec if you don’t service on a regular basis.greet

well matthew.
in my case the to stick with RF was a matter of infra structure.
the tree and branch style of system topology is in our use the best option.
we make temporal RFcircuit’s which have to be rigged fast. tree and branch topology
is in the amount of cabling the best solution for us.
but maybe this is not the case in your situation. when things are fixed this is not an issue as in our situation. if there is a good ethernet system next to the RF streaming video can be a answer for you.
also remember that your not using the service but al the people that don’t understand the system are.
this again was not the question in our situation where a experienced tech had to make and service the network the whole day.maybe you have to sketch your situ a bit more in detail

i guess that’s the best answer you can give bob.
every 10 years you will be banging your head thinking i should have chosen the other one.
my opinion. think about it real good (yes not the answer you asked for). but don’t change to much. if you have chosen stick with it for a while. the bigger the variation in your archive the bigger the problems will get in the futuregreet

well this is a discussion that will go on for ages.
mater of taste yes in the production process.
no in the broadcast process.
1080P for broadcast is still a illusion. yes it can be done.
but no they don’t because we want to squeeze as much channels in the bandwith as possible.
can you imagine that you have to miss al these non saying channels 😉
it’s more the question 720P or 1080I. they need aprox the same bandwith.
but do have there do’s and don’ts
next to that consumers or no brainers which rule our business are turned on by numbers.
1080 sounds better then 720.greet

that’s a nice project.
well important is of coarse the resolution but also the gap.
if the plasma’s are like the orion infinite wall then you don’t have gap’s but with conventional display you have the housing what you have to calculate is the number of pixels per centimeter or inch.
when scaling is used you have to calculate the signalpixels per centimeter / inch
measure the edge of the display and make these gap’s also in your composition’s otherwise the leg’s of the walking people seems broken ;-). don’t forget to look how the scanning is of these display’s there often overscanned which you have to take in acount.
some display have a integrated vidiwall mode maybe you can use this feature to minimize the count of players. driving the display’s native playback will need a extreme budget.
have a look at adtec they have good quality playback devices inthere edje series. they can be synchronised over network. but remember this is lipsync not genlocked. other option is dataton watchout.greet

hi matthew
i hope you have enough budget.
i asked myself the same question a few month’s ago and came to the
conclusion that it was way out of budget in our situation. in comparisment with analog you can put your budget into factor 10. the realtime encoders like the tandberg E5788 are very good but expensive. Vbrick also have nice encoders in a more decent pricing. next to that you will need a QAM modulator which i found hard to find if you find one in a decent pricing please let me know. if you want to multiplex several signals on one channel you will also need a multiplexer or a encoder with multiple input’s.
for encoders you can also take a look at linkXP there main thing is wireless broadcast camera systems but they also have universal realtime encoders.
hope this thread will be followed up whith some good suggestionsgreet
