Thank you, I carried on trying with the three way corrector, which was ok and have now bought it into AE and used the levels filter and now looks fine.

Thank you for your reply.

Thank you so much! i’m sure i’ll run into may more problems but you have really helped with this. thank you 🙂

[Rachel Knight]

Thank you all so much! this is such great help. Have done as you all suggest and seems to be working as it should now!

Just one more quick question…

With the ProRes settings. I chose ProRes 4444 as i will be outputting for a large conference screen is this excessive? and ProRes 422 (LT) is fine? – if it is fine do i need to re-import?

I’m working on a imac processor: 2.66 GHz Intel Core 2 Duo. memory 4GB, Mac OSX
Hoping the ProRes4444 won’t slow it up too much? are there problems using this?
but need a good quality output for the large screen.

Thank you so much for your help so far.

Thats great, thank you for clearing that one up!

Proxies sound like a great idea and can see how they will speed things up, will defiantly be using these!
Thank you!

My preset is defiantly 788×576. I’m using After effects CS4 and in the link you sent, under the heading ‘Upgrade pixel aspect ratios to correct values’ theres a table and it says…
Pixel dimensions in CS4, PAL D1/DV square-pixel equivalent= 788×576
(which doesn’t make sense as it doesn’t divide 4:3) but theres a high chance im reading something wrong, I also found this on it …

As the preset gave me this value 788×576 i locked the ratio and typed in 1080 and it gave me 789.

If the preset said 768×576 (which make sense) then I guess I would have got 1080 x 810 – which is now the resolution im using…. phew!

As it stands I am building my comp… 4:3 1080×810 square pixels to be projected via the laptop.

If the hotel turns around and tells me it has to be for DVD and i’ve built it for square pixels how do I change it to look right for rectangular pixels so logos ect look right?

Thank you again and sorry to be a pain…

[Rachel Knight]

Will use square pixels! Thank you for the link it was very helpful, think i’m starting to understand abit more…

Sorry for the confusion…
The hotel screen is 4:3 ratio.
The presentation will be projected either via a laptop or DVD played on a laptop or DVD player.

In the comp settings I have chosen the PAL D1/DV square pixel setting which gave me 788×576.
I locked the aspect ratio and made the width 1080×789, this is now a custom setting

I hope I’m right in thinking I have a ratio of 4:3 and building at (1080×789) a higher res than 788×576 square pixels and this (1080×789) can be scaled down to 788×576 if needed to be put on a DVD.

Thank you both for answering so quickly, this is my first ever forum post, so i’m impressed, its nice to know there are people out there to help, can’t believe I haven’t done this sooner!!!

My output is either a projector running off a laptop so will use square pixels but if it is a DVD running off a laptop, (projected) or a DVD from a DVD player, (projected) can I still use square pixels? Or do I need to find this out before I can start?

Regarding resolution… Will defiantly use a higher resolution and scale down like Dave says.
I tried the HDTV 1080 25 preset but it looks different proportions to the 4:3 or 720×576.
Could you suggest a frame size in PAL 4:3 bigger than 720×576. I’m unfamiliar with 4:3 and can’t find common resolution sizes for it. I have worked in widescreen 16:9 before at 1280×720 or 1024×576 (i think thats right?) running from a laptop and projected and resolution wise this has been great!

Thank you.

P.S…. Ben – when you say relys heavily on proxies what do you mean? If its to do with computers I work on a mac pro 8 core…?!
