When inserting the same MP4 file in MovieFactory 7 SE, and in VideoStudio Pro X3, some properties differ:
Duration: 900.129 seconds in MF, 1800.259 in VS
Frame rate: 47.952 frames/sec in MF, 23.976 in VS
All other properties are identical.
As a result, when I create a AVCHD disk, it contains only 50% of the video.
Any idea of the origin of this? How to correct it?
Thank you

Re: Bug in recognition of MP4 files
HBi Visatown -- welcome to the forums!! 
Would I be right in assuming that the video comes from one of these new Panasonic (or other?) camcorders that film in true progressive mode i.e. 50 fps? That would certainly account for the differences in properties...

Re: Bug in recognition of MP4 files
Some MPEG-4 variations can be "difficult". Is that the original format? Did you create (or re-create) the file with Video Studio, or did you just open it and check the properties?
It might help to create an MPEG-2 file (with Video Studio), feed the MPEG-2 into Movie Factory, and let Movie Factory create the AVCHD file. ...Ideally, you'd like to avoid the extra conversions because it can degrade quality, but you may not have a choice. If you do convert to MPEG-2, use the same resolution & framerate that you want on your final disc, but use a higher bitrate, since MPEG-2 is not as efficient as MPEG-4.

Re: Bug in recognition of MP4 files
Hello,
The MP4 did not originate from a Panasonic cam corder.
I just made another test.
I converted a mpg to a MP4 in VideoStudio.
The properties say: duration 6.700 seconds, and frame rate 30.000 frames/sec. This is correct.
When inserting the mp4 in Moviefactory, and asking the properties, the properties screen (exactly same layout as in VS) gives the same information, EXCEPT: duration 3.350 seconds, frame rate 60.000 frames/sec.
