Transcode .ts files

[Jaggy]

I am setting up a postprocessing batch file & I am trying to find out the quickest method to transcode SD .ts recordings to .mpgs for playing back on the MVP. I don't care about compressing them at all I just want to be able to fix up timeline errors so I can skip/resume on them.

Using the standard ffmpeg line in my postprocessing batch file

Code:

ffmpeg -y -i "%~dpn1.ts" -vcodec copy -acodec copy "%~dpn1.mpg"

gave me stutter & sync issues.

Using Mencoder

Code:

mencoder "%~dpn1.ts" -oac copy -ovc copy -of mpeg -mpegopts format=dvd:tsaf -o "%~dpn1.mpg"

gives me good sync etc. but skip is a bit "hit & miss"

Using this line

Code:

ffmpeg -y -i "%~dpn1.ts" -vcodec mpeg2video -b 2400k -acodec mp2 -s 704x576 -f dvd "%~dpn1.mpg" targetExtension=".mpg"

is great but is very very slow to transcode

I have also tried

Code:

ffmpeg -y -i "%~dpn1.ts" -vcodec mpeg2video -me zero -intra -b 2400k -pass 1 -acodec mp2 -s 704x576 -f dvd "%~dpn1.mpg" targetExtension=".mpg"

but it is only slightly faster

I don't have any experience in this field & really don't know what I am doing.....help:o

Try:

Code:

ffmpeg -y -i "%~dpn1.ts" -vcodec copy -acodec copy -target dvd "%%dpn1.mpg"

I use
-vcodec copy -acodec copy -f dvd

Works quick and no sync issues.

Thanks for the replies, I'm still testing & could be for a while....I wish I knew more about this stuff

At the moment my postprocessing.bat looks a bit odd doing 4 transcodes on the one file <grin>

So far "-vcodec copy -acodec copy -f dvd " gives me sync issues, the others all work to some extent. I think it may be a case of picking one & using it for a week or so to see how it goes.

Although more input from you knowledgeable people out there would be very welcome.
