What h.264 videos can be imported? I've tried to import h.264 contained within mp4 and RAW (*.264), and most of the videos weren't supported (none of the raw).
I tried to put H.264 elementary program stream content encoded with MainConcept's "Reference Encoder" (a separate product from MainConcept) and it crashes (divide by zero error) Vegas 8 Pro. This problems was reported to Sony.
I've found to make these files more compatible with other editors if you create an AVCHD disk of the video and use it's multi-plexed .m2ts file container then Vegas can insert them into the timeline.
If I create a h264 video using the MainConcept encoder in the ulead software Vegas will not directly load these files. But after they are Multi-plexed into a .m2ts container (by creating either an avchd or Blu-Ray disk) then Vegas can read the m2ts file correctly.
thanks for your response, I'll try if it works - but I'ld prefer to be able to open mp4 (and mkv - but sure that won't be posible) directly from Vegas.
What program did you use to create the m2ts?
You can also render with Vegas 8 and the AVC-Encoder, using the AVCHD 5.1 templates (project must be a 5.1 project). This material can be reimported in Vegas.
