SageThumbs 2K 0.5.0
SageThumbs 2K 0.5.0 — Explorer thumbnails for 313 file types Windows can't read, plus a right-click image toolkit.
What's new
- 🎬 Video thumbnails, done properly — Explorer now reliably shows a thumbnail for your videos, and it's a representative frame from about a third of the way in (not the black intro, fade-in, or studio logo). Covers MP4, MOV, M4V, MKV, WebM, AVI, and WMV.
- ⚡ Fast even on huge 4K files — for MP4/MKV we read the video's own index and pull just the single frame we need (a few MB) instead of scanning the file, so a folder of multi-gigabyte movies on a slow drive thumbnails quickly — and can no longer peg a CPU core or leave blank tiles that never resolve.
- ℹ️ Formats Windows itself has no codec for (MPEG-1/2 .mpg/.mpeg, Flash .flv) keep the normal file icon — nothing can produce a thumbnail for them without an installed codec.
