Video format for broadcast
on Dec 16, 2009 at 3:37:36 pm

Up till now i have done three tv commercials but i am a bit unshure if i am getting the best videoformat from the client and if my workflow is ok.
I would really need your help.

I am getting interlaced Blackmagic uncompressed 10 bit 4.2.2 quicktime files with framerate 25 FPS and a size of 1024*576
I think that they are stretching the file from 4:3 but i am not shure.

I then do all my work in a 1050 * 576 composition (i need to stretch the footage a little to fit the dimensions)

When i am done with the promo i render out a QT animation with fields and compresses it to a mpeg master with telestream episode

The finished file is a mpeg 2 with the dimensions 720*576 with 16:9 par

Does all this seem right to you video pros??

Is this a good workflow or should i do it in another way? and should i request some other footage from the client or is this ok?

I am a beginner in broadcastdesign therefore all the questions and i would be greatfull for all your input

Where are they being delivered for broadcast and what are the specs that they require? I wouldn't finish anything in MPEG2 format unless I had to or it was destined to be a DVD. Let us know what the end result of the commercials are and what the delivery specs you have been given are and we can help you.
