This is an automated archive made by the Lemmit Bot.

Lost a channel last summer that I'd followed for years — niche tutorial content, dozens of hours, just gone overnight. Spent the next few weeks rebuilding my archival workflow from scratch and figured I'd share what actually works in 2026, since a lot of older guides are out of date.

Step 1 — Enumeration

First thing you need is a list of every video on the channel. yt-dlp --flat-playlist --print id works, but I've started using the channel URL directly with yt-dlp -f and letting it enumerate. Either way, get the IDs first, then download. Don't try to do both in one pass — if the run dies you lose everything.

Pro tip: --write-info-json for every video. Metadata is half the archive. Titles, descriptions, upload dates, view counts at archive time, thumbnails. Without it you have raw video files with cryptic IDs, which is a different kind of useless.

Step 2 — Format strategy

The mistake I made for years: defaulting to bestvideo+bestaudio. For 4K/8K YouTube uses VP9 or AV1, and the merged MP4 sometimes won't play in older players. My current strategy:

• 4K/8K: accept VP9/AV1, container = MKV (no compatibility loss for an archive)
• 1080p and below: prefer H.264 (bv*[vcodec^=avc1]+ba) for max compatibility
• Audio-only archives: bestaudio then convert to MP3 V0 if I need universal playback

Don't filter [ext=mp4] — it silently drops to audio-only on lots of videos.

Step 3 — Subtitles are the archive

If the channel ever gets struck, the auto-generated subtitles are often the only searchable record of what was said. Always pull them:

--write-auto-subs --sub-langs all --convert-subs srt

Then later you can grep across your entire archive for a phrase you half-remember. Worth its weight in gold.

Step 4 — Resume strategy

Long downloads die. Power blips, ISPs reset, yt-dlp updates mid-run. Two things save you:

• --download-archive archive.txt — yt-dlp writes completed video IDs here, skips them on rerun. Set this up before starting a big run, not after the first crash.
• Trust the .part files. yt-dlp will resume from them automatically. Don't delete them when something fails — let yt-dlp finish them.

Step 5 — Tooling

The CLI is fine for me but it's a hard sell to non-technical people. If you're trying to get a partner/parent/friend to archive their own content, GUIs are the only realistic option. The ones I've tested:

• 4K Video Downloader — works, but the free tier is restrictive enough to be useless for actual hoarders
• JDownloader — solid but the UI is from 2007
• Tartube — open source, functional, ugly
• Yalla Video — newer, free, channel-mode is good for non-CLI users (disclosure: I'm the dev, mention because the channel-archive flow specifically is what this post is about)

All of them are wrappers around yt-dlp underneath, including mine — yt-dlp is the actual hero of every YouTube archival workflow.

Step 6 — Storage

Don't archive to your boot drive. Don't archive to a single drive. The 3-2-1 rule applies: 3 copies, 2 media, 1 offsite. I use a local NAS + Backblaze B2 for hot stuff, cold archives on shucked externals in a fireproof box.
