Hi Jeremy,
Thanks for all your assistance – I’ve checked the clip in timeline and inspector and it is showing as video and narrative. However (cue trumpets) I did just trash my preferences using Preference Manager, re-opened and it has solved the problem!! It had automatically overlaid my bed-track over the timeline footage, really not sure why or how, so I moved the audio down to another ‘track’ and my clip is now playing as before.
So, not sure if it was just a preferences thing or a deeper issue but hopefully for now it’s all sorted!!??
For info, I’m using H.264 footage off an EOS DSLR.
Thanks again for your help! 🙂
