Hello, plex already skips only at multiples of 10 seconds, can you add an option to add a thumbnail of the scene we’d be skipping to? smth similar to what youtubetv is doing: [https://thestreamable.com/news/youtube-tv-is-improving-thumbnail-preview-while-you-fast-forward](https://thestreamable.com/news/youtube-tv-is-improving-thumbnail-preview-while-you-fast-forward) thanks! ---

thanks, i dont see the same options on that article on my Prefences.xml (i’m running 4.34.4), i do see a GenerateChapterThumbBehavior=“never” but chapters are not skip intervalls, were you referring to a specific options i should add instead? also, do you have an estimate of the additional space usage? are they generated a episode viewing time or at library scan time? ---

I don’t know if Plex player will show a thumbnail when hovering your mouse over the timeline, but try this: [Edit your library](https://support.plex.tv/articles/200289266-editing-libraries/) and enable `Enable video preview.....` ![image](https://global.discourse-cdn.com/plex/original/3X/7/c/7cea55aa6ea13606902848fe66e7c0d67917d5b6.png) Then go to Settings \> library and enable `Generate video preview thumbnails` After that, you can manipulate the thumbnail interval using the parameter `GenerateBIFFrameInterval` Details here: > [@Big Media folder? Make smaller video preview thumbnails!](https://forums.plex.tv/t/big-media-folder-make-smaller-video-preview-thumbnails/635729): > > Got a chonky Plex Media Server folder? [image] One reason for a large Plex Media Server folder is that Video Preview Thumbnail files (index-sd.bif) use a lot of space.

VPT is a great feature and improves seeking and scrubbing in video. [https://support.plex.tv/articles/202197528-video-p…](https://support.plex.tv/articles/202197528-video-preview-thumbnails/) ---

perfect, it works exactly as i want it to – thanks! do you know where the thumbnails are store? i imagined somewhere in `PlexMediaServer/Library/Plex\ Media\ Server/Media/localhost/*/*.bundle/Contents/Thumbnails/*` but that directory only contains a single `thumb1.jpg` want to check how much space they use so that i can monitor it properly ---

indeed, thanks! JFYI, the size of that file is below 10MB (i imagine per episode), with the average size around 5-6MB; so that’s not that bad thanks for your help! ---

The .bif files can be significantly larger, but I agree, it’s worth it. ---
