Figuring out the best way to turn Tubi live TV in to a movie file. First save the stream:

• Open https://tubitv.com/live in a browser, and start playing a channel
• Hit F12, go to Netowrk tab, and filter on "m3u8"
• Right click on the last listed m3u8 and copy the URL

• timeout 2 100m yt-dlp -o "filename.ts" "URL"

Chop into "pretty close" pieces with ffmpeg:

• ffmpeg -i "filename.ts" -c copy -ss 0:00 -to 11:11 part1.ts
• ffmpeg -i "filename.ts" -c copy -ss 22:22 -to 33:33 part2.ts

Other parts needed:

• audio/video codecs
• crop
• scale
• audio level

reassemble:

• ffmpeg -f concat -i filelist.txt -c copy output.mp4

last pass

• ffmpeg -i output.mp4 -c:v libx264 -preset slow -c:a aac -b:a 128k -ac 2 finaloutput.mp4
