My Pentax K-r records video in .avi format (mjpg codec). When I convert it to .mp4 or any other format, I can hear a loud sputter (?) every second. I do not know how to describe this, so I am attaching both .avi and .mp4 file so you can hear it. It sounds like someone was tapping the microphone or like that sound in headphones when you plug them in to audio source.
AVI Sample - original
MP4 sample - converted
I am curious if you too will hear that sound.
Second thing is that when I play the .avi file in Media Player Classic I can hear that strange sound, but when I open the same file in Windows Media Player the sound is OK. It's the same on every computer I tried. Also it is ok while playing directly on the camera.
I was recording and converting videos from my Pentax K-r many times and never had this problem before. Videos that I recorded some time ago work just fine.
Today I spent like 4 hours trying to get rid of this problem. I tried removing and installing codecs and other software but with no luck :(
Do you think this is could be a problem with my camera?
thanks in advance for your help
