I'm experiencing a frustrating problem.
I recently bought a Samsung HMX-H200 full HD camcorder. I record at 1080/50i (AVCHD/MP4). When I connect the camcorder directly to my television (an old standard PAL television, scart/composite connection), the recorded files play back as they are supposed to do (very smoothly).
But when I edit the files on my pc, I always get this jerky effect, the video loses its smoothness. I edit the files with PowerDirector 8, but I also tried with MovieMaker, which gives the same problem.
I tried using all kinds of export settings, going from WMV to AVHCD, going from progressive scan to interlaced (top and bottom field first), and using different frame rates. Always the same jerky result...
The loss of smoothness can be detected when viewing the files on my pc, but is also very noticeable when viewing the edited movie on my television. The finished movie is put on a Samsung Story Station, which is connected to a WD HD TV Live player, which is then connected to my television (composite/scart).
I experienced the same problem when converting my old VHS tapes. Using my DVD-HDD recorder, I recorded the VHS tapes to DVD discs. Those DVD discs played very well (smoothly). But when I ripped those DVD discs to WMV i.e. the same problem occured: smoothness was gone. The files still played back well, but not as smooth as when the DVD discs were played back. Finally I resolved that issue by buying and using TMPGEnc MPEG Editor 3 to rip the DVD discs. Instead of ripping and re-encoding the video, I think TMPGEnc just kind of 'copies' the original MPEG-2 files from the DVD discs without altering them. Those 'ripped' files play back very well on my pc ánd on my television (through the WD HD TV Live player): very smoothly; no loss whatsoever.
So my question is: what exactly is causing this loss of smoothness??? I am now desperate. I believe I have tried everything...
Thanks for your help.
