thumbnail image

[stormdog]

Probably been asked before but a quick search didn't turn anything up. Not been using Avidemux long, but I notice the image in some thumbnails are taken from the first frame, while in others it's taken from a frame around 4.5 seconds in. Do I have any control over which frame the thumbnail is taken from?

Video thumbnails are generally out of control of Avidemux as the latter doesn't support adding attachments to video containers which offer such a feature (MP4 and MKV). Still, it is up to the thumbnailer invoked by the file manaher whether to use such an attachment as thumbnail or to generate a thumbnail out of the video stream (I personally would prefer the latter).
