Help converting 24 FPS to NTSC DVD

[mikeveli]

Hey,

The clips I am attemping to convert are the following format:

XVid codec
23.976 FPS
Eencoded in HDTV Progressive

I tried to bring the clip into TMPGEnc and everything seemed cool but when I went to re-encode the file it was telling me that the total length was 93 mins (the actual length is only 43 mins)!?!? I tried with 3:2 Pulldown selected and deselected and there was no change.

So my question is, what is the best way to get these clips onto NTSC DVD?
Should I do the long process of converting the video and audio to 29.97 FPS (which I have never been successful at) or should I just leave it at 23.976 FPS and let the DVD player to the decoding for me? If the latter option is more suitable, can I be guaranteed that every NTSC DVD player will decode from 23.976 to 29.97?

If I leave it at 23.976, how do I get TMPGEnc to keep the original length at 43 mins? I would like to have at least 2 clips on 1 DVD, but this is not possible with this weird time increase. Please help!

Thanks,

Mikeveli

Taht happens when the AVI is corrupted. Did you check it for bad frames in VDUB?

You encoded it as 23.96 fps with 3:2 pulldown enabled and it will play fine. However, you will probably want to interlace you output if you going full or 1/2 D1.

I loaded the file into virtualdub and I got an error saying something about there being a Variable Bit Rate and there would be a 20000ms delay in audio or something. I tried to play the file through in Vdub and the audio was all crackly. How do I go about checking for bad frames and once that is done, what do I do to get this file converted to an NTSC DVD? Thanks,

that's caused by you avi file having vbr audio. click ok to the message and continue to scan for bad frames.

try encoding the file again.
choose 23.97 fps and use 3:2 pulldown.
process only the video stream (es - video only)

the change in length is most likely caused by the vbr audio.
you may have to process your audio and video separately.

I think I'm trying to encode the same files as you are. I used CCE as my encoder and left the frame rate at 23.976. Afterwords, I used Pulldown.exe to change it to 29.97. I tried playing the DVD on my DVD player with and without using Pulldown.exe on the MPEG-2 file. There was a lot of flicker in the picture when I didn't use Pulldown.exe but all that was eliminated when I did use the program.

Basically you need to extract the audio from the Xvid file into a PCM WAV file.

Then do JUST the video with TMPGEnc or do the AVI as the video source but your extracted PCM WAV audio as your sound source.

That should "fix" the probem with TMPGEnc having "fits" over the running time of the video.

You should encode at 23.976fps with 3:2 pulldown. It is easy to set-up using the wizard mode but the wizard mode will not work correctly unless you import that PCM WAV audio file as your sound source.

FulciLives: What would you recommend I use to extract the audio into a separate PCM file? Is it ok to still use VirtualDub even though it's giving me the VBR error?

And when using 3:2 pulldown in TMPGEnc, do I just have to click the check box or is there other stuff I have to do? It also seems to me that by changing the video to 29.97 using 3:2 pulldown, the audio will still stay at 23.976 and be out of sync. Thanks for you help,

It can be done with VirtualDub but probably the safer way is to just load it into GOLDWAVE then save as a 16-bit Stereo PCM WAV audio file. Use 48k sampling rate if it will be used for a DVD.

And when using 3:2 pulldown in TMPGEnc, do I just have to click the check box or is there other stuff I have to do? It also seems to me that by changing the video to 29.97 using 3:2 pulldown, the audio will still stay at 23.976 and be out of sync. Thanks for you help.

It's easier to just use the WIZARD MODE because it will set it up correctly for you.

Also don't feel bad this trips up many newcommers but NTSC is the same running length be it 23.976fps or 29.970fps

No need to change the running time of the audio.

When using the wizard do I select 3:2 pulldown or should I just leave it at 23.976 and let the DVD player do the decoding?

If using WIZARD mode you don't have to select 3:2 pulldown as it does it for you.

Look at the VIDEO TAB and you should see this:

FRAME RATE: 23.976fps (internally 29.970fps)
ENCODE MODE: 3:2 pulldown when playback

That's all you need.

Do NOT select 3:2 pulldown on the ADVANCED TAB

Increase the directshow filter priority in environmental settings and the xvid length should be correct. Also by doing this I don't need to convert the audio.
