When creating a video contact sheet (Create > Video thumbnail gallery...) with specific setting a thumbnail is truncated.
Settings used:
Width 1024
Columns: 2
Spacing: 0
Rows: 2
The video contact sheet generated contains 4 thumbnails which are all in a line. (Bug - should be two rows). The thumbnail at the very right is truncated, only about 10% of the thumbnail can be seen.

This still doesn't work right as of v1.95.4.
Take a video of your choice and set the columns and rows fields to:
If you use the same value for columns and rows or the aspect ratio of the video (4 coumns and 3 rows) it'll fit - from what i've tested.
Take a video of your choice and set the columns and rows fields to:
- unequal values and
- not the same as the video's aspect ratio
- contact sheet width: 1024
- columns: 5
- rows: 3
- (video aspect: 4:3)

Get the bugs fixed, THEN start adding features. It sucks, but someone has to do it.

So, has anyone tried this? Any confirmation?
I thought it through once more, and i'm pretty confident it's a rounding issue. If the result of the resizing procedure doesn't result in an integer, it'll be impossible to exactly fit the images into their place.
The procedure is probably just rounding, while it should always round up and then, at the end of it, crop the image to specified width, with top left alignment. It shouldn't end up with more than 2 pixels cropped ever. But there will be no more missing screenshots.
