Anamorphic composition and render
on Apr 13, 2013 at 12:07:28 pm

Hi Guys,

I have been scouring the web for this but unfortunately did not seem to get a good understanding so I have to resort to posting my question and will be extremely thankful if you could help out.

Basically, I have to deliver a video for broadcast. Here are their format requirements:

output format: Quicktime.mov IMX50 anamoprhic, Pal, Video encode: D-10/ IMX, Audio Encode: PCM
frame: rate: 25
frame rate mode: Progressive
resize: Active Picture: w- 720 h- 576, Frame Size: w- 720 h-608

Encode profile 50mbps Mpeg2 4:2:2@ML

Audio Profile GOP Structure I-Picture Only

This is my first time of delivering for broadcast and im panicking.

My composition settings are: HDTV 1920x1080, 25fps, Square Pixels

I am able to find an IMX50 codec, I think I will also be able to identify correct settings for the audio.
What I don't understand is how to export a correct anamorphic 16:9, I don't even know what steps to take in order to achieve this.

I someone could please take a minute and explain to me what render settings to set up in oder to export the video to the requirements above. Do I need to fiddle with the composition settings or can it be done in the render process?

Please help me out if you have a spare minute, I will be extremely grateful.

Thanks

George

Thank you for your reply,

Could you please have a look at the attached pictures whether my composition settings are correct (picure 1).
The composition that I get is 4:3, should I render it as it is (picture 2) or scale it so it is widescreen (picture 3).

I do not fully understand what anamorphic is so could you please advise which one of these will be correct according to the resolution delivery requirements mentioned earlier. Which one of these is the correct 720x576 anamorphic?
Thank you

No re-scaling. You want your image to be squeezed because it will be stretched back in playback.
Study a bit about anamorphic - it's something you should know:
