Here are the four user jobs I commonly use:


mythar --chanid "%CHANID%" --starttime "%STARTTIMEUTC%" --title 
"%TITLE%" --subtitle "%SUBTITLE%" --outdir /home/public/video/Archive 
--passthrough --interlaced

mythar --chanid "%CHANID%" --starttime "%STARTTIMEUTC%" --title 
"%TITLE%" --subtitle "%SUBTITLE%" --outdir /home/public/video/Archive 
--passthrough --vsize 1280x720

mythar --chanid "%CHANID%" --starttime "%STARTTIMEUTC%" --title 
"%TITLE%" --subtitle "%SUBTITLE%" --outdir /home/public/video/Archive 
--passthrough

mythar --chanid "%CHANID%" --starttime "%STARTTIMEUTC%" --title 
"%TITLE%" --subtitle "%SUBTITLE%" --outdir /home/public/video/Archive 
--passthrough --interlaced --vsize 1280x720


I call these:
Mythar Interlaced

Mythar Progressive to 720p

Mythar Progressive

Mythar Interlaced to 720p


They do:

Recode at the same resolution, maintaining the interlace

Recode to 720p, assuming progressive content (most things besides
sport, news, dance etc.) are progressive

Recode at the same resolution assuming progressive content

Recode to 720p, deinterlacing the content and encoding at twice
the original frame rate (note, doubling the frame rate doesn't
make a lot of difference to file size).


All of these methods, pass through the audio without recoding it,
so you don't lose 6 channel audio where used.
