[mythtv-users] FFMpeg optimal settings for 1080i

[Joseph DeGraw]

I have been working on an issue with HDtv 1080i recordings being burned
to DVD for playback. It seems with the default settings for mytharchive
(mythtv .27-fixes, Mythbuntu 12.04) it takes a abnormal amount of time
to burn a dvd. After alot of reading I came across a thread at the
ffmpeg forums that was very helpful and also listed a command line for
getting the job done alot faster. Infact, It took me about 20 -30
minutes or less to get a 1920x1080 movie recording onto a dvd with good
quality. Below is the command line that I used.

ffmpeg -i "Fatal Honeymoon.mpg" -filter:v
"scale='if(gt(a,720/480),720,-1)':'if(gt(a,720/480),-1,480)',pad=w=720:h=480:x=(ow-iw)/2:y=(oh-ih)/2"
-target ntsc-dvd FatalHoneymoon.mpg

Im far from an expert in converting video but what Iam now looking to do
is incorporate this into mytharchive instead of what they have listed in
their ffmpeg_dvd_ntsc.xml file. Has anyone done this before?

Perhaps this will be more work than what I imagine I dont know. However,
The basic idea is that my girlfriend would like to burn her recorded
movies to dvd to take with her and play on a basic dvd player while she
is away. The mytharchive was taking too long to do this but perhaps with
a bit of a rewrite of some settings it can be alot quicker.

Well,  Thats my project anyways. Comments are welcome :)
