| Is it possible to set the thumbnail image for a video, preferably with an IEBitmap? |

Hi
Where do you mean? When the thumbnail is displayed in a TImageEnMView?

I'm thinking that I would like to create a thumbnail that is saved back to disk so that when the video is displayed in Windows Explorer, as a file, the thumbnail shows up in the Windows Explorer preview instead of the first frame of the video. Is something like this possible?
I've seen .THM files and I understand that these serve this purpose, but I'm lost on how to manipulate them.
My thought is to grab the frame I want to serve as the thumbnail and to replace the .THM. Or, if there is some way to accomplish this by embedding the thumbnail in the movie file, this might be better.
More guidance would be much appreciated. |

Hi
THM files are not used by Windows Explorer. It generates its own thumbnails as needed. I'm not sure there is any practical way to provide custom thumbnail, as you would need to override the application that Explorer calls to generate a thumbnail for the particular file type.

| Thank you for the response. Do you know how Windows determines which frame to use as its thumbnail? I assume it is the first frame of a video. If so, is there a simple way to insert a single frame at the start of a video, something like a one frame title page, so that Windows would use it as a thumbnail? |
