Hi

I been instructed to create Pan/Scan Menus. I've worked with Menus that are 16x9 and then Letterboxed in 4x3 - with 2 sets of 8 bits - but never Pan/Scan. Could someone give me some directions on design and authoring? I need to start on this tomorrow and figured I'd post this now to get a head strart so I don't spend a whole lot of time spinning my wheels :)

Thanks!

Crop 90px left and right from your wide sub and stretch from 540 to 720

Sorry...don't mean to be dense. Are you saying you still need 2 8Bits? I figure you'd only need 1. Also could you give me a little more detail on the size and what settings in Scenarist need to be changed?

It is mandatory to define at least one 4:3 display mode and each display mode needs its own sub so you need at least 2 8bits (wide and p/s).
To create still p/s tracks in scenarist you must change 'Default Settings' - 'Still' - 'Aspect Ratio' to '4:3 (Pan-Scan)'.
If you choose 16:9 you cant define p/s.
Video tracks has to be encoded '4:3' and 'pan-scan' enabled (to avoid reencoding use Restream to change flags)
To enable p/s for each track in track editor - property browser change display mode to your needs (Only Pan Scan or Both).

Creating 8 bits:
Depends on your workflow
(Stills, ITU 601 PAR)
I start with 1050x576, create background, new layer for wide sub etc.
For P/S sub: new layer, edit the inner 788x576 area as subpicture -> resize this 788x576 area to 720x576 8bit BMP.
For generic PAR use 1024x576 and 768x576 for resizing to 720x576.

My menus are motion....So your saying I need to to encode a 720x480 NTSC 16x9 Anamorphic as 4x3? Then take that into re-stream and set the flags to P/S....Correct?

No - if they are already encoded as 16:9 you should use restream to avoid reencoding
For new encodings use 4:3 and P/S enabled...

Ok..let me get this straight..here are my steps.

1. I design my menus 854x480(NTSC) then resize to 720x480 anamorphic
2. I encode 16x9 in Compressor - which doesn't support P/S flags
3. Bring my newly encode file into restream and set flags to P/S

Hope I'm on the right track.

Also where and how do we change the P/S flag in restream?

Encode 4:3 in compressor and set P/S flag in Restream

(You can change 16:9 to 4:3 in Restream too)

What a great help you are! Could you explain Sequence Display Conditions? What exactly happens to the stream when I add 540 to the horizontal size?


I now have the stream in Scenarist. For the subpictures it only give me a choose of Wide and Pan/Scan - which is good!

Now for the 8 Bits -

I have a 720x480 8bit which i placed in the number 1 position and set the button to Pan/Scan. What are the dimensions and settings in Scenarist for the Wide 8Bit?

Is it the same settings in the Advanced Effects Window and dimension as in this thread?

Restreams writes "display_horizontal_size" in "Sequence_Display_Extension"

Create all your subs to 720x480, no need to edit anything in Advanced Effect window. Just fit buttons as you do with letterbox subs.

Thanks

So your saying I need to use 720x480 8bits for both? Perhaps the same one? I did this and my wide looks fine but the P/S is off.

Yes

No

Take your wide sub, crop 90 px each side and resize to 720x480 and use this as PS sub

Got it...it looks great! Thanks for all the help!

One more thing...I'm a little confused on the encoding.

Could explain your statement a little more:

No - if they are already encoded as 16:9 you should use restream to avoid reencoding
For new encodings use 4:3 and P/S enabled...

I've been using Compressor on the mac to do my menus. Since it has no P/S settings, I would encode 4x3 where usually I would encode 16x9...correct? Basically could you explain the differences in your statement and how restream would treat a 4x3 and 16x9 encode.

Sorry...I'm almost there :)

Yes

A clip used in Scenarist for P/S authoring requires following settings:
Aspect ratio: 4:3
Pan Scan enabled: yes

If you encode to 16:9 force Restream to patch AR from 16:9 to 4:3 and display horizontal size to 540
Encoding to 4:3 requires Restream to patch display horizontal size to 540 only (no need to patch AR)

Ok...Now what about stills? I normally bring in tiffs and author from there. Could you give me the recipe for this as well?

Nevermind..figured it out by marking it P/S Scan in Data Editor
