I am digitalizing Super 8 film with a dedicated Somikon scanner.
It outputs H264 - MPEG-4 AVC films in 4/3 (1440x1080). When I open these films directly with VLC, there are displayed in 4/3, which is fine.
Then I add them in Sony Vegas Pro 12 to edit/modify them, but Vegas Pro believes that they are 16/9 clips: although the
Project [Projet] and
Visualization [Visualisation] fields are in 4/3, the
Display [Affichage] is in 16/9 (600x338) by default:
I have to uncheck the
Simulate the peripheral image ratio [Simuler le format d'image du périphérique] item to get back the original 4/3 aspect ratio:
When I render the project, Vegas generates a video in 4/3 with the right resolution (1440x1080), but the video player sofwares (VLC for example, see capture below) believe it should be displayed with a 16/9 aspect ratio.
In conclusion, the resolution is good all along, but the default aspect ratio is wrongly set to 16/9 by/in Vegas Pro.
Is there a way to avoid that in the first place?
Or is there a way to correct it afterwards (once the rendered file is created)?
