When I received the camcorder, first thing I did was test everything. All the buttons and settings worked properly, the picture was clear and everything seemed to be working as it should. When I tried to import the footage to my Macbook the editing software(Final Cut Pro), would not let me import more than a few seconds and no sound got imported with the clip. Just to make sure it didn t have anything to do with my software or the Mini DV camera that I use for importing footage, I recorded some foootage on a different Sony Vx1000 that I have, and the footage then played back with sound perfectly.
When playing back the footage on the camera that I bought the picture is clear but there is no sound, same thing when using a different camcorder to play back/ import footage. The camera does indicate sound in the level meter and when plugging in headphones the sound is perfect. I didn t understand why no sound was recorded since the camera indicates that the microphone is working. When looking it up online I read that people have had similar problems and that most of the time it has to do with a defect in the main board. I would like to return the camcorder and get money back so that I can buy a working one. I would also be open for the seller getting it repaired and then sending it back to me.
