PAL to NTSC or NTSC to PAL – which is easier?
Ok, so we are building a 3D spot and they need to deliver in NTSC and PAL, the question is which is the better way to start? PAL is a bigger frame size, so its obviously easier to shrink to NTSC, but PAL has a lower frame rate, so the opposite applies there. What do you guys think?

Render it twice. Once for PAL and once for NTSC. Modern 3D software gives you the option to define more than one render setting.
A conversion is always a compromise. Converting from PAL to NTSC would be the better choice in terms of the resolution. But in both ways you will get a frame-rate problem. Especially for a 3D animation you need to render at the frame rate you want to deliver the final video in order to avoid any conversion problems.

Unfortunately due to compositing, backgrounds, effects, etc. its impossible to build it twice.

Bummer.
Then I would create the video in PAL. The higher resolution is more important.

Hmmmm
what if you did it at 24 fps? 720p?
then you could add 3:2 pulldown to make it 30, and speed it up 4% to make it 25.
(you would have to speed up any audio as well)
I mean, if you think about it, thats what early film animators did
“I like video because its so fast!”

Have you investigated using Natress Standards conversions?
They work really well.https://www.nattress.com/Products/standardsconversion/standardsconversion.htm
definately worth the price if you plan on doing this more than once in a blue moon.

I would go to the highest practical res and then scale down the to PAL & NTSC. As 1080 60i has the highest frame rate and the same pixel res as 50i, I would use that and scale down to PAL & NTSC.
Bearing in mind the final PAL & NTSC must be interlaced, you might as well go for 60i in my opinion. 24 to 25 frame conversion isn’t as pretty as 29.97 to 25 and 1080 over 720 makes sense to me at least. 60i is 29.97, so it is only the PAL that needs frame interpreting and it is better to start at a higher frame rate than the target.

[Josh Weiss] “PAL is a bigger frame size,”
PAl uses more pixels, and with different size, than NTSC to show the same picture. The picture is no bigger.
It will be always easier to go from NTSC>PAl than PAL>NTSC.
Is easier to discharge 5 frames every second that to create 5 new frames every seccond.
If you are working in AE, you don’t need any standard conversion.
Just drop your NTSC composition in a PAL composition and export with PAL setting.
Easier impossible.
