HI All,

I am revisiting Sync configuration on this post.

I currently have A:

-GRASS VALLEY SCB-200N
-AJA GEN10
-VIDEOTEK VDA 16A (da)

We are moving our facility to a larger space and I would like to set the Reference and sync up properly. Yes, Bob we have sync hard wired up to our Betas, Digi betas, SR, D5, Network encoders (Pipeline, clipmail)and all.

I ordered Red BNC cable to make brand new Reference only cables and again hoping to get pointed in the right direction for this project.

According to what I read and to this post. I think I should design a dedicated patch-bay for Sync/ref only.

Questions on connection:

What should receive NTSC Black Burst and/or Tri-level sync?

what about the gear that takes both an NTSC SD signal and an 1080i 59.94 HD signal?

Should I normalize ALL SD/HD gear to the GRASS VALLEY SCB-200N NTSC black burst signal and manually patch the tri-level when needed like advised in this post? When exactly do I want to patch in the Tri-level?

What should out TEKTRONIX WVR 7200 receive?

Should the AJA GEN10 be normalized to anything in this design?

We very rarely work in 23.98/24p its always in 29.97 or 59.94

Thank you as always and looking forward to your response.

HI,

what do you mean by “lifting the ground”

lifting the cables off the floor?

In addition to video hum rolling through the monitor;

I have an issue when routing composite video input to a beta deck and recording. the monitor feed (composite video out from the beta) displays a wrap around video. Where the bottom of the screen is actually at the top almost as if the video is wrapping around the monitors screen. The position is never the same as each additional tape I put in to record changes the position of the wrap around.

any thoughts?

thank you

Hi Mark,

Thank you for the response. The VANC checkbox is checked and just checked to verify. I don’t think I would have been able to see the captions play from the SR otherwise. Something is funky about the QT closed cap track in this file. I have a work around but would love to get to the bottom of this. Any other thoughts?

going) APR-AJA-HD teletrax-SR
back) SR- pipeline log and capture

FCP log and capture is the work around so either FCP is handling this specific error in the captions track better than pipeline, pipeline is corrupting the captions (again tests say otherwise), something is inherently corrupt on the source QT CC track.

I need more thoughts!

thank you

Thanks Shane,

If you had a QT 10bit uncompressed that came from Adobe premier which QT recognized as “none” (FCP want to match sequence settings or render) rather than uncompressed and wanted to add titles in FCP;

what method would you use? Compressor or Media manager?

This is the first time I even took notice at Media manager so thank you for that tip!

Thanks Rafael,

SO even if you choose 10 bit settings in “FCP export using QT conversion” the footage is really being crushed to 8-bit? Why would we be able to select these parameters if not really using a 10-bit processing?

Update:

green frame issue fixed.

after going back and forth with Sony creative software technical team, we upgraded to build 701 and the issue went away.

HI Steve,

The file I am working with/imported into Vegas is:

:60 sec
Mpeg2
15mbps
720 x 480
4:2:0
Telestream flip-factory trans-coded file

All of our masters sent to TV stations are of this format (currently)

I wouldn’t say the file is corrupt as we have been working in this work flow for several years and do various broadcast production work such as EV encoding, Tagging, delivery, etc. ….but with that being said…maybe have other insights or you can shed some light on something I am missing.

I import the mpeg video file and match the project properties to the video file.

I hope this information helps and please respond with your thoughts and suggestions. While I would rather not loose multiple generations Should I flip or encode as a 720 x 512 4:2:2 file and work with this file in Vega..then flip back to our “Master format”

please advise and thank you!!

HI,

I imported mpeg 2 video files and then adding text over the video. Thats actually all I am doing. As I am clicking within the timeline and editing the text green frames seem to be added as a background of the text which covers the original video. Then they will disappear…sometimes. Really funky thing

what am I clicking that is doing this??

thanks

Thank You Bob and Chuck for all the info. ,

I wanted to calibrate these machines as a learning process and felt it was something that should be done (0vu IN = 0vu OUT) and could be done easily. I guess I was wrong!

We never output from the beta decks or digitize from beta tapes anyway. We dub spots onto beta tapes and ship them out to TV stations across the country.

Yes they are pieces of junk that are far to old. while we focus on digital delivery we still have a couple of hundred stations that take beta sp tapes.

I will certainly focus my attention elsewhere. But a raising concern is that the VU meters on the front of the UVW1800 are extremely unreliable. As we are starting to adhere to the CALM act ..this is an issue.

Right now i am using the VU meter on the 1800 series in combination with the digital peak meters on the DIGI beta deck to monitor the audio on our commercial spots (the spots being adjusted from the flip factory first).

I guess will have to add a dependable VU meter to this equation.

Chuck I will not drill holes and no desire to!.

thanks guys!!

Thanks Bob!

I will check the link and start learning about the controls and adjustable parameters on our VTRs.

thanks again,
