24p via m2t and mencoder

[bmaltais]

I am proposing an alternative to get to 1440x1080 24p. I have looked at all the proposed solutions but I was not really happy with them. So I tought of the old trusty mencoder. Guess what, it can do a pretty good job at extracting the 24p frames from the 60i m2t stream.

Use the following command:

mencoder test.m2t -noskip -vf pullup -ofps 24000/1001 -oac copy -ovc lavc -lavcopts vcodec=mpeg2video:vbitrate=24000000:aspect=16/9 -of mpeg -mpegopts format=mpeg2:vbitrate=25000:vframerate=24000/1001 -o output.mpg

One could easilly create a batch file that would go through a full set of mt2 files and convert them to proper 24p PS mpeg2 files.

Unless something has changed, I don't think mencoder works consistently:

Or a bit easier to read:

Hopefully something else will be possible sometime in the not too distant future.
