I just upgraded my computer. I had a video editing workflow all working on my old Windows XP computer, but I am having problems with my new Windows 7 machine.
My video contains a mixture of camcorder source (1920x1080 60i)and helmet camera source (1280x720 60p). All source has been transcoded to Cineform HD.
After editing, I render to AVCHD 1920x1080 60i as a .m2ts file. I then play the result on an HD Media Player. This all worked fine on my XP machine, but on W7 the camcorder material has serious ghosting/stepping problems. The helmet camera material looks great.
After running a series of tests I have found that the ghosting problem only occurs when I have transitions or cross dissolves in the video. If I just abutt the clips, everything works fine. But as soon as I add a transition the image quality goes to pot. It may be a field reversal problem, but I am not sure.
I have tried different project settings and enable/disable resample - all with no effect.
There are actually two problems:
1) If I try to render directly to .m2ts with transitions in the video, the render never completes. It hangs up on a transition and will sit there for hours. It does not crash - it just never progresses. This is an inconvienience, but I have a work around - I render to an intermediate form (Cineform HD) and then re-render to .m2ts. If anyone knows how to resolve this issue, I would appreciate it.
2) The rendering causes ghosting in the image on any camera pan or fast moving object. The 60p material is clean while the 60i material is ghosty. I do not know if this occurs in the render to intermediate form or in the render to .m2ts.
If anyone has any suggestions for resolving this issue, I would appreciate it. The ghosting makes the videos unusable, which makes my computer upgrade a total waiste.
Thanks,
