I am making a movie (just a figure singing) in Poser
When I do the final renders of my images what render size should I use (I already have it set up for 720x540 with a safe area for TV
Is the quality good if I render them at 720x540 and then take them into Adobe add music and  finalize the movie
I hope I made my self clear

One problem that you'll encounter isn't just the dimensions but more the pixel aspect ratio.

Computers use a 1:1 pixel aspect ratio.  Standard TV is 4:3 and High-Definition TV is 16:9.  This is the x:y pixel size - that is, on a computer, pixels are square whereas on TV they are some rectangle.  I don't think Poser's renderer can compensate for aspect ratio.  "Constrain Aspect Ratio" only pertains to the render dimension not the pixels.

On the actual dimensions,  you'll need to determine the target audience.  NTSC (US) and PAL (Europe) standards use different screen dimensions.

kuroyume0161: thank you for the reply
I forgot to add in my thread, when I take the movie into Adobe or Virtualdub I will resize it to 720x480, I think that should get real close to limited stretching on the TV
,but I am not sure about the quality

As long as you are rendering from Poser as single frame images at at least 30 fps, you should be good.  Most video (TV, movie, DVD, etc.) is at around 29.97 fps (making 30 fps close enough for conversion).  It is better to render the frames as single images because you are not involved with formats or compression issues (esp. mpeg-ing).  This provides the most control.  And Adobe After Effects and Premiere both work with these easily.

AE and Premiere can compensate for aspect ratio, but it can get tricky.  When I did renders for a DVD intro-outro in Cinema 4D, I set the aspect ratio in the renders there (the renders looked stretched on the computer) but the results out to TV were perfect (using Pinnacle DV500 for TV output preview).  So, you'll have to find some way to verify your results in that respect without having to produce the entire thing.

Thank you. I will render out images and then let premiere do the rest
which did you render out in png or tiff?

TIFF

Thank you I use tiff
