IVTC Full Screen NTSC with 29.97fps source?
 

Kwag,

I thought I saw somewhere that you encode Stargate episodes. Do you capture full screen NTSC at 29.97fps? Then, does the IVTC function work for you, or do you just leave it alone? How much video can I expect to fit on a CD (80min) with a full screen capture at 29.97fps?

I didn't get very much success at all with fullscreen (my this case, a DVDrip), but IVTC to make it 23.976fps is pretty much a must. It helps a lot.

I got into this VCD "hobby" primarily because I wanted to save programs captured from cable, things that will not make it to DVD. As such, I have had little success with IVTC. Does that mean that specials on TV and even some shows cannot be converted with IVTC?

Well, only things shot on Film and meant for the NTSC audience can be IVTCed. Things like Music Videos, TV Episodes, and Movies on TV are all shot on film (most of them, anyway). This means you can't IVTC a live broadcast, lots of commercials, etc...the only real option is to use a deinterlace method.

Hi all:

I capture my Stargate episodes in a Panasonic DMR-E20. The capture is 29.97 interlaced and I create a project with DVD2AVI from the captured file and IVTC with the decomb.dll filter in a AviSynth script. Then I encode with the 352x480 template. I capture from an analog channel in satellite T5 every Friday morning.
Never fails 8)

Sorry to beat this to death, but since I lack the intuition to read between the lines, and plenty of Internet bandwidth, here goes. Kwag, when you do a capture, is it an uncompressed AVI? Then what? How do the pieces fit together? I know that you are active over on the vcdhelp boards, so you probably saw the post about the guy who used PowerVCR to do a realtime capture/conversion at SVCD res. What do you think of that post? I will try his suggestion at a much higher bit rate to see if it is good enough to be a source because I do not have the disk space for uncompressed AVI files 8O .

@Plant_Guy

I capture with the Panasonic DMR-E20. It captures directly to MPEG-2 in a DVD-RAM. Not uncompressed video.
I then take that DVD-RAM to my PC, and transcode that with the KVCD templates to MPEG-1.

I am also testing the Pinnacle Bungee for real-time capture. The thing captures at an awesome quality.

I haven't read the post at vcdhelp that you mentioned.

AAAAAAHAAAAA!!!!! Yes, I said it out loud, and that felt good, thank you :lol: . Kwag, excuse the outburst, I read all the guides concerning the hardware you mentioned as well as AviSynth and DVD2AVI, and what I take away from your previous statements is this (correct me if I have it wrong): Do a high quality capture to mpeg-2 format doing whatever I have to. Once we have this file, create an AviSynth script to run IVTC on it along with any other filter we might be needing, and then run TMPGEnc and load your template(352x480), and then on the file input dialogs, open the AviSynth script, and let it encode! BWAHAHAHAHAAAA!!!! I think I drank one too many Red Bull's this morning 8O .

8O 8O 8O Yep, definitely one too many! 8O 8O 8O

Just a question
 

Correct me if I'm wrong, but wouldn't it just be easier to capture the original television broadcast as 23.976? I've never tried it, and I don't know how it all works, but that would seem like the easiest thing to do.

Of course, I'm a newbie and I don't know anything... :twisted:

Re: Just a question
 

It can't be done DrChumley.
All NTSC broadcasts are done at 29.97, because that's the television standard.

kwag

OK, since nobody finds me amusing, let me ask again in a more correct way:

1) Capture TV show in HQ mpeg-2 mode
2) Create AviSynth script with appropriate filters
3) Open .a2v file and .wav file with TMPGEnc with Kwag template already loaded.
4) Encode and burn to CD as non-compliant VCD.

Is that the way?

TomG. - aka Plant_Guy

Almost!.
First you load your .avs and then your wav file. Then you load the template. That's always the last step.

kwag

So let me see if I got this right. You have to open your mouth BEFORE you insert your foot! By golly, I got it! :o

guys is there a program that can convert 29.97 to 23.97 if my source is an avi or mpg? but not a dvd rip

A DVD rip is an mpeg file. TMPGEnc can be used for this purpose, but if the source was not telecined, then you cannot just convert to 23.97fps.
