DVD encoding using ffmpeg

Thursday, August 31st, 2006

This post is just for me to remember some information on creating DVD video. If you have no idea what ths is talking about, feel free to ignore it.

This works on Windows and Linux. Feel free to do something with it if you want. I found this information on Slashdot. I take no credit for this information. Thanks to those on Slashdot for supplying it.

=================
ffmpeg -i INPUT.avi -target ntsc-dvd 01.mpg
mkdir dvd
dvdauthor -o dvd -t -v 4:3 01.mpg
dvdauthor -o dvd -T
growisofs -Z /dev/dvd -dvd-video dvd
rm -r dvd 01.mpg
=================
=================
fmpeg -i INPUT.avi -target ntsc-dvd 01.mpg

I'd recommend, as a minimum:

ffmpeg -i INPUT.avi -async 1 -hq -b 5000 -ab 224 -target ntsc-dvd -y output.vob

Play with the numbers 5000 and 224 until you have an output file that'll fit on your 4.7gb disc. The formula is (number_of_seconds * total_of_bitrates) / 8 / 1024 / 1024 = megabytes of output. You'll need it to be less than about 4400. Aim for 4200 if you don't want to have to reencode if it runs too high, because ffmpeg is a variable-rate encoder that just aims for the target you specify and often seems to overestimate how much data it can put in.

DVDAuthor's a great way of mastering the DVDs and learning to produce menus with it can be fun. Both of these programs work fine on Windows.

I am using:
ffmpeg -i myvid.avi -async 1 -target ntsc-dvd -b 4208 -ab 160 -y 01.mpg

New Photos Available

Monday, August 28th, 2006

I have just posted a bunch of photos. I've probably left out a lot of good ones, but wanted to get some new ones out there. Yeah, I'm a slacker. Also, this batch will not be good enough to print 4×6 photos from. It would take an eternity to upload them all if I did. If you see one you like, let me know and I'll get you a high resolution copy suitable for printing.

Enjoy!!

Update

Saturday, August 5th, 2006

Nothing much has been going on. We came back from Alexandria Sunday night, and we went back every night they played. They went into the finals (Wednesday night) undefeated and lost two games to finish in second place. We enjoyed watching them play so much we don't know what to do now.
We are currently helping Grammy in her classroom. Wes is putting up a rope to hang her alphabet cards. He is taking a break to have a tasty beverage and some M&M's. I decided I would get on here and update. Emma Grace is still not into walking. We have been trying it, but she wants no part in it. She is currently watching Grammy's “ish” swim in the newly cleaned tank. Tuesday night while I was feeding her at the ball game, I asked her if she wanted more and she did the sign for more. I almost passed out. I asked her again and she did it again. Wes has a picture of her doing it at the house. It has been a while since he has updated pictures, but maybe he can get some up soon. Well, I better get back to work b/f they fire me. Until next time….
