No.12458 mahlemiut Developer Mar 11, 2016, 21:12	Snapshots and AVI always default to 1:1, ie: the actual resolution used by the system. You can use -snapsize to force a specific resolution that you wish to use and MAME will stretch or shrink the output to that size.
No.12460 Tafoid Administrator Mar 12, 2016, 19:26	As mentioned, the internal resolutions are used to display 1:1 in snapshots and videos unless otherwise specified. This is not a bug but a design of the system to ensure data is presented accurately. Closing as this is intended behavior.
