what tool to split >3 hr recordings?

[tunanugget]

is there free tool do you use to split long mpg recordings (such as a 210 minute college football game)? i.e. u'd prob record in 'nedium' mode or what cbr value would u use? and then divide into 2 4.7 gb dvd's

[wannabepvr]

Is that 30 minutes of play + 180 minutes of commercials?

- If so Comcut might be an option.

- Otherwise I have used TMPGenc for small stuff (cut - under the 'tools' menu) but not for anything this big. I don't know how it would go.

video-redo is the thing for you...it even has it's own simple commercial detector
i've found it to be the best thing for quick edits and cutting of shows...very nice interface and does a nice job at the cuts...it's pay, but very nice for this sort of thing..[and not too much $]

or you could use mencoder and just give it a start and stop time and do a 'copy' for codec...[free]

The answer is it depends...

Are you looking to divide the files and then (for archive purposes) then join them later into one coherent file?

If so I have had great success with the freeware HJsplit

You can define the split file size to suit your needs and join the files later for viewing.

Hope this helps.

well, can you post a sample code?

[tunanugget]

i basically just want to put the a large mpg file such as movie.mpg that's 7 gb.

Split int into a 4.5 gb chuck and 2.5 gb chunk to fit on two discs.

Burn the disk.

and be done.

hmmm,it can only cut on a time so you'll have to figure out how much time you'll get on the first disc...or you could just devide the total time by 2 and use that..

Code:

ffmpeg -i "%~1" -t %2 -target ntsc-dvd -acodec copy -vcodec copy  "%~dpn1-1%~x1"
ffmpeg -i "%~1" -ss %2 -target ntsc-dvd -acodec copy -vcodec copy  "%~dpn1-2%~x1"

use: make it a batch file...say..cut.bat
cut.bat "movie.mpg" 1:30:00
-would cut the movie at 1hr. 30 mins..
giving you movie-1.mpg and movie-2.mpg

forgot ffmpeg can do too...and you already have it...

neat...i'll have to try it. is it dvd-compliant?

i posted same question in dvdrhelp forum so i'll update u guys on if they had any other suggestions. dunno if mencoder is more reliable or ffmpeg.

=======================================================
based on this wiki code: http://en.wikipedia.org/wiki/MEncoder:

mencoder -ovc copy -oac copy -ss 0 -endpos 700mb -o movie_part1.avi movie.avi

as well as code from one of the comskip/comclean batch files....


my code is like this:


==================

split-1sthalf.bat

"c:\program files\mplayer\mencoder" -ovc copy -oac copy -of mpeg -ss 0 -endpos 4500mb -o "movie_part1.mpg" "movie.mpg"

==================

split-2ndhalf.bat


"c:\program files\mplayer\mencoder" -ovc copy -oac copy -of mpeg -ss 4490mb -endpos 8000mb -o "movie_part2.mpg" "movie.mpg"

==================

this assumes that mencoder is stored in program files; that your movie is movie.mpg, and that it's 8000mb.

my question is if anyone knows how to create a 1step batch program that will ask for input of file name/directory; find the file size or ask to manually input file size; divide it 2 to split between two dvd-r's w/ some overlapping time (i.e. 3s); and output the result as two new files.

or, similar idea as above, but drag a mpg to batch file and it splits in two.

can u modify the code so that on part two, it starts of at 5s prior to the split? i.e. if 2 hr program, split occurs at 0->60:00 for first show, and 59:55-end in second file. also, is original deleted?

in sample of 308 mb mpg, it split it into 131mb and 148mb = 279 mb.
