I tried to fault find as instructed but I am a computer novice.
I still have problems with PE8.
Here are my details:
Dell XPS Studio 8100
Intel icore 5 processor
Win 7 Home Premium (64 bit)
Panasonic HDC-HS9 Full HD 1920 X 1080P
Video format: AVCHD Video, 5.1 channel
File extension: .m2ts
I'm not sure what a Codec is!
When I first installed PE8 on my PC it worked ok. I could put the video files into the Timeline and run them smoothly with the sound coming out ok.I created a couple of DVD's no problem.
Now when I use PE8, I can preview the files and they run smoothly with sound. But when I put them into the Timeline the clips run very jerky and no sound comes out. When I create a DVD the DVD comes out with a great picture, but with no sound.
At the moment I can edit and create my DVD's with the Panasonic HD Writer 2.5E for HDC. But I bought PE8 to give me more options.
This is a bit of an Audio Checklist, and might point up something amiss. There are differences between the player in the Project Panel, and playing from the Timeline.
Also, one thing that trips up a lot of users is trying to begin editing, before the program has had time to Conform the Audio. This is a two-step process, as first the CFA files are written (32-bit, floating-point files for editing), and then the generation of the PEK (Waveform Display) files. There is a little progress bar (blue) on the lower-right of the GUI. One should wait until that completes.
