You are trying to edit video made on a STILL camera, like making a phonecall with a hammer. Unless the recipient understands morse code and is within hearing distance, your message will not be understood. Convert the material to DV AVI type2 before importing into PP.
Thanks for your reply.
Interesting - as I mentioned the video does play fine except in PP and AE.
How would you suggest converting as you describe on a Mac?
I'm having some joy with MPEG Streamclip.
If I convert my files to AVI with the setting Apple DV then I get files that look reasonable and are not jumpy in PP. They do appear a little pixellated and I need to switch audio to uncompressed otherwise it removes the audio.
Also there seems to be no option for Type 2. (You can select codec, and these include PAL DV, PAL DVPRO, etc. but not much else for export type)
Is this the kind of approach you were thinking?
