I recently purchased two PMW-EX3 cameras for use here at my work, and I thought that I had them up and running perfectly but recently ran into a problem importing footage. When I shoot anything over around 13:40:00 long, PP CS4 will not import the entire length of the clip, only the first 13:40:00 (give or take a minute or two). When I play back the clips on the camera or in Sony's clip browser software I can play the entire duration of the clip. When I'm in PP using the Media Browser window to get to my footage, it even shows me the correct duration of the clip in the Duration column, but when I copy it over into my project bin, only that first 13 and a half minutes makes it. And a similar problem importing the files from EX3 into After Effects. AE only imports the first MP4 file of your clip and not the rest.
I've searched lots of other forums, and while I've seen various issues with importing XD EX footage into PPro and AE, I haven't seen this best solution yet.
Sony PMW-EX3 can shoot XDCAM EX MP4 recording with true 1920x1080 resolution on dual SxS cards. As the XDCAM mp4 footage still cannot fully supported by some video editors like Adobe Premiere Pro and After Effects on Mac. So if you are using Premiere and AE for editing just like the above user, the best workaround for us is to convert Sony PMW-EX3 mp4 to Adobe Premiere Pro/After Effects most compatible MPEG-2 format, and it will make the editing work much smooth and easier.
