I have a Panasonic GH4 and normally film in MOV format at either HD or 4K. A customer with a GH2 said he had problems with AVCHD footage from his GH2, so I tried the same thing with my GH4.
You need to set he camer to film in AVCHD. I filmed @ 1080 50i. Record a couple of clips and then AMA link to them in Avid. If you try and play them Avid either locks immediately or plays for a second then locks. This happens if I AMA link to the volume or the individual files.
Try and transcode the AMA linked files and Avid also locks.
BTW locks = Avid freezes and the computer says Avid is not responding. No other error message.
If I import the clips the old fasioned way, file - import, they import and transcode fine.
If I load the clips into other programs - I have tried EDIUS 7, Premiere and Prelude CC 2014 - they work. It seems to be Avid related.
AVCHD footage from other cameras - I have a Sony 3D camera, plus footage from Panasonic 151, AC90 and others - all works ok in Avid.
My tests are using Avid MC8.3 on a PC using Windows 8. My customer has been using MC8.0 on Windows 7.
Anyone else had this problem?
