Recording an hour and 15 minute teaching session generates 3 MTS files in my Panasonic GX-7.
Used TXmuxer to join the files - looks good and plays well on the Vegas 10 timeline.
Tried to render to mp4 using MainConcept and Sony encoders, each time I get an unexplained error and resulting file that is always 4.0X GB. Trying to render any one of the MTS file results in the same problem, again with a 4.0X length.
All drives are NTFS.
Any thoughts?
