vegas 7(9) and 1080i mp4 with a lot of motion
hello:
my source is 1080i mp4(60i) from samsung camcroder. The subject is skiers and there is a lot of motion. The original mp4 video does very well with the motion. But when I render from the original to HDV mpeg2 or 60 fps 720p mp4 video I see ghosting artifacts in the clips which are not present in the original.Are there any work around this problem. How best to preserve the motion integrity of the original?
thanx

Two things come to mind:
1) make sure that your project properties are set to match the video event sources. When you go into “Project Properties”, there is a little folder icon in the upper right corner that will help you select a source file and set the proejct properties auto-magically to match.
2) You can try to set, on all of your video events, the “Disable Resample” switch. Select all of your vide events, right click, “Switches”, “Disable Resample”. That should remove the ghosting.

thanx:
I was doing some more experimentation.
Now when I take the original clip and run just ffmpeg in command line I get the same or even more severe ghosting.
But in the command line if i put -deinterlace switch I get rock solid video.
so the procedure I have successfully implemented is the following
1. run ffmpeg in command line and convert the original mp4 to get a deinterlaced mp4 with the same quality. You have to make sure the deinterlace option is the FIRST option in the command
2. use the output from 1 as the source for vegas
this procedure works.
I wonder why newer equipment put out interlaced video in the first place
