I often re-convert many TV shows to “Optimized for TV” these days, as many shows (WEB_DL, etc.) are frequently over 10 mbps.
I’d rather use Custom, unfortunately it has the following drawbacks:
the lowest available Custom quality is 8 mbps for 1080p. That’s too much. Most shows optimized with “Optimized for TV” end up being around 5500 mbps.
Custom choices are not saved ! (why ? it’s possible to give a name, but it’s not saved) so I’d had to make the quality selections every time
Shows optimized with Custom settings are saved to folders with random names, even different folders for each encode batch, that’s annoying (I actually get the optimized files and use a script to overwrite the originals !). The name should be fixed, based on the choices made, or based on the Custom Name entered by the user… if it is saved (see above).
