Upscaling Interlaced SD to HD 1080i
Hello everybody!
I want to upscale SD video file to HD. So I used Distort -> Transform but got problem with the exported file.
The exported file looks jumpy and I see duplicate frames during playback. It sounds like wrong interlace setting.
But I set everything correctly. Here’s the detail:Premiere CS4
SD video file: MPEG2 720×576 25fps interlaced
HD project: XDCAM EX 1080i 50i (HQ)
Export setting: MPEG2 HDTV 1080i 25 HQ (I tried both Upper and Lower)Tell me if you need more information 🙁

This kind of upscaling is done via expensive hardware. Software won’t get the same results, but try not using the distort effect. Try using the scale property of the clip.
Better yet, use AE to achieve your upscale and try to work with a codec that’s not compressed like animation MOV.
The repeated frames sounds like a frame per sec miss match. Check a rendered playback of the clip at 100% as the frame rate should be same and playback fine just small.

Thanks for the upscaling method. I also found my problem.
I can’t set the fields in the Premiere CS4 unlike AE 🙁
