The set-up: I am using ArcGIS 10.3. I have exactly 528 raster maps in a mosaic dataset. Each one corresponds to the same geography but at different months (from January 1969 to December 2012). I would like to use time-slider to move through these images and export to a video.
The time-slider animates nicely through the rasters inside ArcGIS, but once I try to export it to an .avi video it skips the large majority of images and I end up with only about every sixth raster being displayed.
Potentially relevant: the time-slider is operating on a string field that is the concatenated year and month (YYYYMM format). I created this field using the field calculator. It looks like this:
I picked this format because it fits one of the options in the Layer Properties dialogue. Note that in this dialogue I do not set the layer time extent because if I have ArcGIS calculate it directly, it decides the time starts at 1/1/0001 for some reason (this is highlighted in the next picture)
So in the time-slider properties dialogue, I change 1/1/0001 to 1/1/1969 and it seems to work fine. From here, the animation works in ArcGIS.
Using the default settings (below) to export to video causes the skipping. When I tested the default settings on a smaller subset (24 months) it worked fine. It's hard to test settings on the whole thing since the video usually takes a long time to export (and often doesn't work if I open any windows over the top of it).
