Hi, i had the same problem.
Took my Sony pmw ex3 footage in HDV 1080 50i, (1440×1080), convert the mp.4 files to mxf with XDCAM EX Clip Browser and everithing looks fine in Vegas Pro 8 with the project properties set to HDV 1080 50i, (PAL). The footage is upper fied first and the project properties assumes the same.
After rendering to DVD architect PAL Widescreen, there they are, the interlaced problem in all movements, specialy the horizontal ones like pans. I tried every fields sets combinations in renderin and in projects, even tried rendering to HDV 1080 50i, AVI, tried the pre-render option,…,… notihng worked out, except… activating the switch “reduce interlaced flicker” on media properties. Took a lot of work to activate the option in every single media clip and the final quality dropped down a bit but the problem was solved, think that can help.
Maby there is a problem wiht vegas 8 pro or with the main concept codec in decoding the new HD formats, i really dont know, but one thing i know, that is not supose to happen. Complements. João Viçoso. Videographer
