Using the DOS command as discussed previously I joined 2 x MP4 music videos to ensure seamless.

The new file plays back fine in Windows Media Player

However after importing it into PD16 for editing the MP4 file whilst there has no video or music

To check it was not a compatability issue I then imported the 2 original MP4 videos unjoined and both played ok

Anyone any ideas on this.

Is there a file size limitation in PD16 causing the problem perhaps as the joined file is 8 gb.

To double check I joined two other videos from the same shoot and had the same problem again only in PD16 though

I think you joined the files via the DOS copy /b command. You cannot join two MP4 files with that DOS command. The video file has information about the content of the file in the so called 'header' of the file. If you join the two files via DOS, you do not alter the header of the first file. So the header is wrong for the joined file. Some programs do not read the full header (e.g. obviously Windows Media Player) and play the whole video data. Other programs do, e.g. PD16, for editing purposes. They detect the wrong header and consider the whole file as "fubar".
You have to join the video files in an other way. Use the googling machine of your choice and search for "how to join mp4". There should be some tools, that helps you.
