OK - this is happening again - now on a 16GB CF card which had old shots on there.
It was full of photos from March 2013 and some videos. I shot some new stuff on Oct 31st.
3 of the videos from March are showing up to import but not the photos.
After some searching the video have already imported.
I may be closer to the reason but am not sure why!
It looks to be something to do with the timestamps for the videos:
For example, movie file already in library:
but in import dialogue:
There is an hour's difference!
Is Aperture treating time differently somehow for video compared to pics? Could it be a camera specific issue? I often forget to change the camera for daylight saving (GMT vs BST).
Very odd. Still concerned with files being added to a CF card if anything has been erased on it, while in the camera, or even in the computer. If the camera tries to fit new stuff within space vacated from prior uses, don't know how to predict.
Whenever you can safely do so, you need to reformate this card in the camera.
Thanks Ernie. I've sent feedback via the usual route as I suspect this is an issue with some difference in encoding time in EXIF vs MOV metadata.
I would not have erased anything from the card in all honesty.
When I've copied a card's content over to several drives I will generally reformat in camera to erase everything.
In this case I'd filled one CF card and the others I had with me were nearly but not quite full, with a couple of 100MB spare on each - for whatever reason I had not reformatted them in camera before travelling which caused a slight doubt that I may not have ever imported them but on returning home it was clear I had.
So in essence this was just a case of removing a nearly full card, then putting it back and using the remaining space without any specific file deletion.
I'm sure you can see though why this issue caused me to doubt the import was completing properly in Aperture with potential for data loss.
I've seen the same issue importing from a DCIM folder I've copied to a hard drive but not imported to Aperture immediately or using older photos with the current library that i had rediscovered from long ago.
Which version of Aperture, btw? If 3.4.5, I will examine my files between image and video. In my experiments with 10.9 and 3.5, I don't think I have imported video.
I have two cards in my D800, and I send all video to the SDHC card, and all photos to the CF card, unless the latter fills up, and the camera seconds to the SDHC.
Yes 3.4.5 but the issue started months ago.
My 5D Mark II only has a single compact flash slot and saves photos and video to the same folder.
I've fiddled with Time Zone setting that LeonieDF mentions in the WC, but didn't help.
I now have a duplicate video project which has 2 versions of the same videos differing only by 1 hour in the time, but import still lists the videos as not imported even though one of the imports matches by time.
