So I will start to say that I have a few timelapse clips that have successfully uploaded to Final Cut Express. I am using large format pictures so I can edit them and pan etc. I am using H.264 compression, 24 frames, high quality and data rate is on auto. Again, I have been able to process a few sets of photos using these settings. However, different sets have yielded a blank white file that has no photos in them. The export appears to work but then goes quicker than it should and creates the empty file. They cannot be opened in FCE saying that the codec cannot be read. I don't understand what the problem is. All the photos were taken with the same camera and are being taken from the same external hard drive. Any help would be awesome.
