Film viewer does not show rudder animation.
50 Cal guns have odd ending "sip" sound (tested F4U 1A in external and chase view).
No way to grab graphic detail settings. This was the greatest perk with AH2 viewer. One can record in any detail or gamma setting, then adjust settings to desired detail and gamma for Film Viewer to use, just before quit from game. This produced much better quality video. Current beta version seems to be stuck at default or whatever.
Also, as FLS' sweet WWI screen shots are able to catch the awesome pilot animation, it would be great to include that animation in film viewer.
