Hi,
I have a Sony DSC-TX7 which is capable of AVCHD 60i recording.
When I convert the .MTS file with Toast Premium 10 (tried it 60p, 30p, and 29.97p, deinterlaced), I see two images in one frame. If a person is running in the video and I pause the video for an individual frame, I see a blurry image of the person's next movement on top of the person.
Is there a way to make this not happen, so that when I stop on a frame I only see one image?
Also, Toast recognizes my videos as 29.97fps. Does 60i mean I can convert it to 60fps, or is it just 29.97fps?
Thank you.

Toast does not de-interlace, despite the export setting implying it does.

Try JES De-Interlacer (free), but first use ClipWrap (not quite free) to turn the AVCHD file into a quicktime that JES can use (ClipWrap does not re-encode).

Another thing to try: Final Cut Express.
Perhaps iLife 09 iMovie also can do it.
