Specify rendered video file thumbnail image frame

[Axe Victim]

Hello, I'm reasonably conversant with Reaper from an audio perspective but I've just started doing some playing with sound design against video. I've searched this forum and the Internet but can't find the answer to my problem.

Once I've rendered a video file (I only have the one file to play with at the moment), everything plays back fine but I've noticed that the thumbnail image used for the file appears to be 74 frames into the actual video. Is there anywhere in Reaper where I can specify which frame to use for the file's thumbnail image?

Any help would be greatly appreciated.

Thanks,

Gordon

Didn't know that. But if there is no way to achieve this in Reaper I'm guessing there could be a special tool for it somewhere in the internet.

Sorry
