Exactly what is INSIDE the video you are editing? Report back with the codec details of your file, use the program below Free program to get file information for PC/Mac http://mediaarea.net/en/MediaInfo/Download - when you analyze your file in MediaInfo and post a screen shot in the forum, do so in TREE view - post your information IN your message, not as an attachment that someone would have to download
Thanks for getting back to me. I've gone ahead and downloaded the programme you've suggested, please find the screenshot below. First time on the forums, apologises but I cannot seem to find anything that'll allow me to place the screenshot in a tree(?) view.
Thanks again for your help, it's appreciated. Cheers.
