The file then exhibits some weird colour artefacts. However, there are two problems doing this - (1) there appears to be no option to export audio with an OMF file, and (2) Avid tells me that the file is the wrong resolution (DV411 not DV420). When I export to OMF using its DV option, and import the resulting file into Avid, the image appears to be the correct size and plays without any interlacing problems. The only export setting in AEX which I've tried and which does not give me this problem is OMF. I can tell these are not the correct settings because when I import the files, I can see in the avid source window, the file is slightly horizontally squashed (I see black for maybe 30 pixels on the left and right side, and the picture information is. I've re-set the footage as upper field first in the AEX settings and it makes no difference. I have tried exporting using the Avid DV codec (.mov files), and my usual DV codec (.avi file). Also, the field movement is not smooth on playback. I can tell these are not the correct settings because when I import the files, I can see in the avid source window, the file is slightly horizontally squashed (I see black for maybe 30 pixels on the left and right side, and the picture information is squashed into the remaining space, so the interviewee appears too thin).

I have tried exporting using the Avid DV codec (.mov files), and my usual DV codec (.avi file). I can export it to Adobe Premiere as an avi file with no problems at all. The footage is a DV lower field first interview keyed against a still image. Codecs are housed inside of videos containers like MP4 and MOV (Quicktime). Codecs that significantly reduce the size of your video file are usually very low in quality. Codecs file size is directly related to video quality. Clearly this is not the best long term option! H264 is a codec, which means it is a tool used to code and decode video files. I think I tried everything suggested here but I never got round this problem, it was taking all day to test various settings so I just played it back out to tape via Premiere and then captured the footage in Avid.
