Question

HD 1.33 PAR and all that

Working in Premiere, I want to UPREZ SD footage that is 1.33 to 1 into a sequence that I wish to be this same 1.33 ratio but in HD (1440x1080 PAR?). 

What sequence preset should I use?  When I choose AVCHD, I'm not finding a PAR option for the 1.33 aspect ratio.  What's more the project monitor is 16:9, and when I bring in a graphic to my sequence, it fills this 16.9 ratio monitor.  What is the problem?

Couple of things - Ann is right, SD footage is rarely 1.33 PAR, if anything it is 4:3 with letterboxing to make it seem widescreen.  If it truly is, then you have two options for sequence settings - you can use AVCHD Anamorphic editing mode - this is a usually 1.33.  Alternatively, you can use a Custom editing mode which will let you change the resolution and PAR to the settings you need.

In terms of your graphic - not sure the behavior you are describing.  Make sure that the graphic you are using is also using 1.33 PAR if that's what you want in your sequence. Graphics should have a PAR baked into them.  If I'm not understanding your issue, can you describe the situation in more detail, like how the graphic was created and maybe give a screen shot to describe the issue better.

He never said the footage was 1.33 PAR.  He just said it was 1.33:1, which means normal 4:3 footage.  Chances are he's just confusing the 1.33 PAR of the HD presets, which don't correspond to anything he's got.

As there is no such thing as 4:3 HD, there are no 4:3 HD presets.  You'll need a custom sequence.

Like all discussions about aspect ratio the subject soon bogs down in semantics, theories, etc. 

Early geeration digital camcorders offered TWO native image aspect ratios, 4:3and 16:9.  In North America's NTSC system the most prevant practtice was that both were registered by squeezing a square pixel image area of 720 by 480.  4:3 was achieved by a horizontal squeeze.

It is projects I shot in this standard definition image aspect ratio of 4:3 that I wish to UPREZ to high def.

Surely this need is so universal that there exists one or more high definition sequence presets to accomodate this need optimally.

Perhaps the ONLY way is to work (as I currently do) within a picture area of 16:9 with side bars.  I can live with this, but my concern is that when my project calls for scaling a graphic to effectively 'zoon in' on it, the graphic intrudes upon the 16:9 picture area outside the 4:3 boundary I desire.  Obviously this violates the integrity of my original project's 4:3 picture area. 

I can't believe I have to resort to masking the 16:9 picture area sides to effectively maintain the 4:3.  In fact, I could swear I have in the past stumbled upon a project preset that gave me a 16:9 work space, but automatically masked for my UPREZed 4:3prject so that I have no issies with the area of graphics in my project that strayed beyond tyhe sides of my 4:3 picture area.

Please, no theories and fussy tangential issues. I just quest to find that magical sequence preset that best accomodates bumping up to high defintion the 4:3 picture area standard that after all dominated both televsion and the movies for most of their history.

Not really.  Upressing usually looks pretty bad.  (At least with the tools most of us can afford.)

And as there are no 4:3 HD formats, there are no 4:3 HD sequence presets.

Are you sure your SD footage is 1.33. That PAR is specific to HDV footage.

Run the SD file through Mediainfo and post the analysis in treeview here on the forum.

Hi, you can customize your sequence in PPRO CC. Click on new sequence, choose Settings box and chose in editing mode, personalise. You can choose now every aspect of your sequence.( I have the french version of PPRO so I have tried to translate the options for you to understand but it can be a little different but I'm sure you'll find.

Richard.
