.Ty ---> DivX??

[grooves12]

What would be the best way to go about taking a stream extracted from the Tivo, cutting out commercials, and getting it converted to a DivX file??

Has anyone out there written a step-by-step on how to do this??

ya. well I use tystudio and then put the mpeg2 from that in drdivx. I get nice and ez divx files.

My much more convoluted process involves using TyStudio to extract elemental streams, BeSweet to transcode the audio to MP3, Gordian Knot to encode video to XviD (should work just as well for DivX), and then VirtualDub to mux the audio/video and to cut out commercials.

Even more convoluted process that I use:

o Tytool to rip the ty
o Tytool to make key file
o Tytool to edit the keyfile and add cuts for commercials, save cut
o Tytool to multiplex/transcoder to 44.1Khz (sometimes) => mpg

o DVD2AVI on mpg to make D2V project file and audio MPA file.
o Winamp for MPA=>WAV
o AVISYnth to bring D2V video and WAV into AVS script (script resizes, deinterlaces, deals with framerate, etc)
o Virtualdub to encode to DIVX AVI using AVS script

It's actually not a long process when you do it a few times. You have complete control with the AVISynth, so if you couldn;t cut completely where you wanted to in Tytool, you can refine your cut points in the AVS script and get frame-accurate cutting.

1. Extract from SA TiVo with mux using JDiner's TyTool 7r6, audio transcode option = '5'. This generates an MPEG-II .mpg audio/video file.

2. Input the MPEG-II file from TyTool into DrDiVx, select options, and process. Output is a DiVx .AVI file playable in Windows Media Player.

Simple and effective, but somewhat time-consuming if you're REALLY resizing/downsampling the video to save space and sacrifice quality. (This is on a 1.2 GHz Athlon :( system with 512 MB of SDRAM running WinXP Pro SP1.)

Maybe it is because I am using the latest Tytool, but if I put the extracted mpg directly in DrDivx 1.02p the output is all choppy. However if I open the mpg first in MPEGVCR and simply resave it and then open in DrDivx, the encode is perfect.

Wow. I forgot to mention DVD2AVI for the D2V in my process, but yours definitely is more convoluted than mine. ;)

I have found that Gordian Knot does an excellent job of creating the AVISynth script for me. I tell it my target filesize and it lets me pick a resolution that will fit. I can crop the video and see the results visually as well.

I've gotta figure out a way to automate some of this stuff, though. I have to cut the stream in TyStudio before extracting so that Gordian can correctly estimate the target file size. After that, I should be able to automate DVD2AVI and BeSweet. If I took the time to learn AVISynth script, I guess I could also automate the XviD encode leaving the final commercial cut and mux in Vdub to be done by hand. That wouldn't be too bad...

Wish I had time to work all that out. :)

For some simple utils to get the job done, there's a bunch of little programs in this guide for AVISynth manipulation:

http://www.angelfire.com/tv2/abmtv/DishplayertoSVCD/c00ki3s_dishplayer_to_svcd_guide.htm

I make my scripts using C00ki3enc VBapp on that page. I edit the resulting file to my needs. I changed out a filter or two that it uses. It's quite configurable. The page may be for making SVCDs, but once you get the AVS stuff going and it works in Vdub, you can go to divx or xvid very easily.
