Kenneth, your pixel aspect ratio on the PCR has to match the pixel aspect ratio you render the images with. I'd guess your TARGA images may have been rendered with a pixel aspect ratio for a NTSC video card, which often isn't 1.0, and the PCR wants an AR of 1.0, causing the problem. First, make sure of the PCR's pixel aspect ratio requirements and re-render with the proper one in 3DS. Hope this helps, -Alan

>>TGA -> film recorder… I don't know about a PCR film recorder, but the film recorder I ususally send TGAs to uses a PIXEL aspect ratio of 1.0. I render 640×480 at 1.0 for low resolution, but often use higher resolution such as 1024×768 or 2666×2000, keeping the pixel aspect ratio at 1.0 and the image aspect ratio (horizontal resolution divided by vertical resolution) at about 4/3=1.3333. This seems to work ok. (The film recorder guy said the device could handle a vertical resolution of up to 8000 pixels – wouldn't that make a big file!) JKJ

Kenneth, Yep, everybody seems to have the answer. We're a Truevision Master Dealer and have sold the Agfa film recorders. Shooting through Photoshop you should definitely use a 1.0 aspect ratio on your rendered images. Rendering can be at various resolutions; we usually used 2048×1536. If you were using Image Assist or QPR, you could easily work with the aspect ratio used for Targa video (generally 1.266 for 512×486). Kevin Krell – Computer Support Associates

Kenneth, I've had trouble with aspect ratio myself when shooting slides. I still haven't got it completely figured out. But Render to 2250×1500 with an aspect ratio of 1.0 in studio. This should give you nice circles, full screen slides, etc. Let me know how it goes. DM
