I have been dealing with this for awhile now.

I am trying to simply take a show that I have a Transport Stream of and re-encode it to a better format so it doesn't take as much space.


Here is what is important to me.

1. Easy, preferably one step.

2. Edit out unwanted content

3. Use the codec of my choice(Xvid)


I am close but not quite their yet and I hope someone here can help.


1. First I use HDTV2MPEG2 1.10b to convert the TS to MPEG2.


2. Next I open the file in Vidomi. Choose the 1 hour show to take up 700mb, VBR two pass.

Then I goto "Select Output Range" I edit out the content I don't want and decided if I want to crop.

Then I encode. About 3-8 hours latter I have a great file.


Now this is obviously a two step process. I wish it were one, but Vidomi won't open a TS file.

I can't keep the AC3 file I have to convert to mp3. I would prefer to keep the AC3.

The other problem is that the "Select Source Range" controls are missing because the window doesn't scale well to 1080, it works great for 720.

If I edit the files with HDTV2MPEG2 before Vidomi, the sound is off sync by the end of the show.

If I edit the file afterwords, the key frames are not in a good location, so my transitions between edits are bad.


I have tried WM9 encoder it just crashes(when I open the TS file), I have spend too much time, and don't feel like re-installing my OS just to use it.

What kind of tuner do you have? I think you can just choose whatever codec you want with something like a hauppauge.

if you could figure out a way to do all that, you'd be a rich man. you want the same thing that everyone else wants. from what i've read, though, there doesn't seem to be an easy way to do it. currently it's still a long, complex process.


i've given up on trying to convert my .tp files to something else. i settle for editing out commercials & stripping null packets. doing that, i've been able to squeeze a one-hour show onto one dvd.

I intend to get this to check it out.
Yeah, I have seen that.

I should of mentioned that I

1. Won't pay to beta test software.( they should pay me)

2. Won't pay $200.00 for this software.


But after it has been out for a while and it receives constant raves here, then I may re-consider.


Thanks.


What I did realize was that Vidomi is open source, and it almost does what I want it to.

It needs to

1. Support AC3

2. Edit 1080i, not just 720p

3. Open TS file directly so I don't have to use HDTV2MPEG.


I have a couple of friends that know C++ very well, I think I will ask them for a favor. But it is a long shot.

I wonder why the creator of Vidomi hasn't had a release in over a year.

I have been converting OTA HD (CSIs) with WM9 for a while (31 shows so far). I use the HDTV2MPEG2/DVD2AVI/AVSynth/VirtualDubMod method. It would be great if there was a one step method but I haven't found anything that would give me the file I wanted except this. I do gross editing with HDTV2MPEG and output a single .ts file. Generate a .d2v file and the AC3 file with DVD2AVI that is used with an AVSynth script to feed VirtualDubMod. You can use any codec you prefer and mux the AC3 into the output avi. I use the WM9 VCM so that I can access the encoder. The files I generate are @ 2gb or less doing 1 pass vbr quality 90 and are 1280x720 w/ the original AC3 sound. Yes there are alot of steps but once it's setup the process is pretty painless.

I prefer a two step method myself.


First, use DVD2AVIT3 on the transport file(s) to create a .d2v index file and the ac3 file. This step runs fast and doesn't make a copy of the video.


Second, use Virtualdubmod/Avisynth/MPEG2DEC3 to remove commercials, mux in the ac3 audio, and encode to Xvid or WM9.


Optional third step. Burn to DVD-R.

Isn't that 4 steps?

Well, maybe. Depends upon how you count them.


But it is only 2 program steps you have to run and the file only gets converted once. Avisynth and MPEG2DEC3 are used as functions of Virtualdubmod here.


One of the reasons I do it this way is because ac3 has some requirements in how you cut blocks when you are editing. I don't understand them but tend to believe that Virtualdubmod tends to handle it better than HDTV2MPEG2. Plus, another very tiny advantage. If you edit the commercials in Vdubmod you don't have to cut on key frames since it is working with uncompressed frames.

I have seen a couple of very complicated howto on this technique do you have a favorite howto?

Anyone tried Dr. DivX? This works for me on single pass mode, but crashes on 2-pass. But it will do it all in one step, read TS, and convert to DivX.

Tom & others, I'd appreciate a few more specifics on your 2-program method:


"First, use DVD2AVIT3 on the transport file(s) to create a .d2v index file and the ac3 file. This step runs fast and doesn't make a copy of the video.


Second, use Virtualdubmod/Avisynth/MPEG2DEC3 to remove commercials, mux in the ac3 audio, and encode to Xvid or WM9."


My PC card is by AccessDTV. I believe I've successfully applied DVD2AVIT3, and get the resulting .2dv and ac3 files. (But note that even though it appeared that I was downloading DVD2AVIT3, my downloaded icon is labeled simply "DVD2AVI2"). BTW, I'm recording/capturing, using the recorder program with the Access card, one (of the 3) streams from PBS-- OTA.


As a next step, which file is loaded to Virtualdubmod? How are Virtualdubmod/Avisynth/MPEG2DEC3 combined/configured to work together and are there any plugins that are essential that wouldn't be included in the "full" downloads I did?


Finally, my goal is to burn DVDs (RW) of very high quality HD to playback on a Bravo D1 player (DVI out to DVI in on a Toshiba HD-ready 34HD82. My initial plan, to output DVI from my Radeon 9700 Pro TV-out directly to the Toshiba has floundered, so this is my Plan B). The Bravo claims to support Mpeg1, 2, and 4, and Divx. Is one of these best for quality? For ease of conversion of the TS files? Many thanks . . . Tim

I've used Dr. Divx with mediocore results.


you need to make sure you have codecs that can read ts streams reliably(elecard codec works fine). The resulting divx video, even at the highest quality settings is a big step backwards from the original source. IMHO WM9 is a better alternative at higher resolutions and bit rates.


The easiest, and most reliable way to remove commercials and make sure your video file is standard is to run it through onair's HD editor

Ok I found a fix for one of my 3 problems.


There is a way to edit while encoding with Vidomi. (General options)

So for now I will just run the files through HDTV2MEPEG2 first, and deal with MP3 sound.


It may be possible to open TS files with Vidomi.

It crashes when I try it, but so does Windows Media Encoder, and DVD2AVIT3

So it may be because of my direct show issue.

I wrote a guide describing how I do this. Lately I've been experimenting with xvid and think it may be a better sweetspot for quality/compression than WMV, but it is hard to tell. There's a lot more to tweak with xvid and I'm still learning what all of the impacts are.


Anyways, here's the guide http://www.patjames.com/hdtvtowmv.htm I guess some people find it useful, it's the #1 hit on my site and comes up as the 3rd google hit on hdtv2mpeg


same process for xvid, just pick a different compression codec.

I have read your guide and you have done a great job.


DVD2AVI crashes when I open the TS file.


You have motivated me, to figure this out.

I really need to get a known good TS file to try so I can eliminate the source file as the problem. Do you know where I can find a file to use as a test, so I can work out my DirectShow problem?


Thanks

The DVD2AVI version is a special version available at trbarry.com. That is also where you will find MPEG2DEC3.
