# Media Filetype Handling

## Thumbnail previews

- UPDATE: Nothing needed beyond Windows 11 for most types.

- SumatraPDF install option has checkbox for thumbnails of PDF files.
Okay to re-install using that GUI install method 
on top of a chocolatey install of that app.

- Use "K-Lite Codec Pack" (A/V codecs)
for thumbnails of every media filetype (MKV, PDF/CBR, ...)

- H.265 [HEVC] requires licensing
- x265 [HEVC] is Open Source equivalent.
- H.265 seems to code more vibrant color than x265; DivX vs. Handbrake
- Transcode times for HEVC @ 720p on i7400T
