  Video codecs and formats questions for broadcast

  Posted by Bruno Silva on September 17, 2009 at 10:26 pm

  Hello to all.

  I have just started to work in broadcast , doing motion graphics and editing movies for comercial spots. ( Pal System, my area)

  And I get stuck with some tecnical question that I need to understand so that I improve the quality of my productions and my workflow.

  The company works this away.

  A camara man films (using a Dv cam) what we need and then brings the camara and gives me a uncompressed file , with .mov format that , with the frame size 720*576 with pixel aspect ratio 1,09 , lower field, uncompressed Yuv 8 bit 4:2:2, and 11 minutes is like 13 Gb of space (at least that are the settings I get when I imported it to test it in AE)

  1 Question.
  For me to work this files, what the best format and codec, I should use to compress so that I work with smaller files that my machine can handle.

  2 Question
  During my workflow I need to do pre-renders some parts of my animation that have video and complex effects that slow down a lot the computer.

  I tryed to use mpg2 using the Pal DV High Quality Adobe media Encoder settings tha uses codec: MainConcept Mpeg Video .
  The pre-renders looks good but when I do the final render the stuff that I pre-render just look bad , loose a lot of quality.

  So the question is what the best format and codec, to do, the between stuff (Proxies,PreRenders,etc). So that I can do the final render and the image is cryspe and clear.

  3 Question
  For final quest what is the best format to deliver to create the BETa Cam that is deliver to TV .

  Thanks to all that can give me some help.
  And sorry for any mispelled word .

  The company is new and we are at this point very limited. So I just hava a simple desktop machine with 4Gb ram, double core 2.4 and some random medium g-force, dont remember the model , but is nothing special.

  I use the Adobe software workflow.

  Adobe Premiere editing movie and Adobe After Effects creating the effects ,
  the audio voices I just get it from other person that do the voices,
  and the musics I use SonicFire Pro .

  For compreension I use what the Adobe media encoder offers .
