I have captured some footage using my Sony digital camcorder passthrough and edited the footage using Premiere 6.5. I then created an avi file using the Canopus DV codec and cropped the video a little all round to get rid of edge effects. The final avi looks great when viewed on tme computer. I then ran the avi through CCE 2.67 but the mpeg file has weird motion artifacts when viewed on computer or TV. I tried different settings in CCE (0, 1,2) for line shifts, but they all had the same problem. I also tried TMPGEnc with both even and odd field settings and they also showed the same effect. In fact everything I tried except the MPG encoder that came with Premiere showed the same artifacts. Encoding with the premiere encoder gave perfect results, but that bypasses the cropping settings. So I turned off the cropping in Premiere and tried again and this time the CCE and TMPG results were perfect. So in the end I recreated my avi file without the cropping and used TMPG to encode with it doing the cropping and the result was perfect. Any ideas why Premieres cropping should give this wavy motion artifacts, but not noticeable in the avi, only after encoding to mpeg?
