PAL -> NTSC using BeSweetGUI

[Mickey79]

Ave,

I've converted PAL to NTSC before, long time back, using BeSweetGUI. I remember having PAL AVI and using BeSweetGUI to convert it to NTSC AC3 to author to DVD. I used the Presets provided for the conversion and selected "PAL => NTSC (25.00fps to 29.970fps)" since my Video had been encoded to NTSC (29.970) using TmpgEnc.

However, i repeated the process again after a very long time, and couldn't get the right results. The audio is sounding as if it's playing in fast forward. It's not proper. Why is that? I know that converting 25.00 fps to 29.970 fps means you're playing more frames per second then originally... but it has worked before. What am i doing wrong?

I don't get it.

Any help appreciated.

Thanks,
Mickey79

You want to use NTSC (23.976fps) not the NTSC (29.970fps) option.

Also it is a good idea to make your input file a 16-bit 48k Stereo PCM WAV file FIRST then when you do the FPS conversion go from your PCM WAV file to a new PCM WAV file. Finally you can convert your corrected-for-length PCM WAV to your final format ... AC-3 in your situation.

However there is a new method right now that has just been pioneered (for lack of a better word).

Here is a link ---> CLICK HERE

The benefit of this new approach is that you end up with a progressive NTSC compatable video file that is the same length as the original PAL video ... the audio therefore does not need to be adjusted for length.

Please note this method is very new and I'm not sure if it is going to work with 100% of the DVD players out there but early reports seem very promising. I haven't had a chance to try it myself just yet though.

Hi FulciLives-

I can't believe the nonsense being spewed in the other thread to which you linked. I think I'll go and give them a piece of my mind.

DGPulldown works great. I've converted progressive sources from 20-25fps to NTSC DVD using DGPulldown, and then tested on about 10 different DVDPlayers, software and standalone. It works fine on all of them. This site has more of those PAL to NTSC questions than does Doom9, and maybe DGPulldown will help put a stop to them.

I just found out about DGPulldown the other day so as soon as I can try it myself I might as well write a guide on how to use it.

I have a couple of posts I send people to where I essentially wrote guides on how to do PAL to NTSC the "old fashioned way" using the techniques pioneered by Xesdeeni but I never wrote a guide that is submitted in the guides section on it.

Now with DGPulldown out the time is here for such a guide I guess.

Unfortunately I haven't had a chance just yet to try it but I understand the process and can clearly see the great benefit of it.

You want to use NTSC (23.976fps) not the NTSC (29.970fps) option.

Ave,

Thanks guys for all your posts.
My first problem is this... i have a PAL AVI. I want to convert it to NTSC so i can author it & burn it to DVD.

I used TMPGEnc Xpress to convert the video from PAL to NTSC and encode it to m2v video file. The problem is... in BeSweet i can select PAL -> NTSC (23.976) ... but when i'm converting the video... i don't get an option, i just get PAL or NTSC. And what happens is, my output m2v NTSC video file is 29.970 and not 23.976 .... Now if i convert my audio to 23.976 .. won't the video (29.970) and audio (23.976) be out of sync.. even if they are both NTSC ?

Is there a way that i can select the video output to be 23,976 instead of 29,970 in TMPGEnc Xpress ?

Thanks,
Mickey

Ave,

I had never heard of DGPulldown before... and it seems very interesting. Does it convert audio or video or both from PAL to NTSC ?
I'm at work now, but as soon as i go home i'm going to try DGPulldown.

Thanks,

I had a question about DGPulldown.

Can i do this ...

Encode my PAL AVI to PAL MPEG2 Video using TMPEGENC
Load the PAL M2V file in DGPulldown
Use the Custom option and define 25.000 -> 23.976
Convert it and thus get a 23.976 NTSC MPEG2 Video as output

Then use BeSweetGUI and convert the original PAL AVI to AC3 using preset PAL -> NTSC (25.000fps -> 23.976fps)

And then use my TMPGEnc DVD Author to author the DVD using the end resultant m2v and ac3 file ?

Exactly! Just make sure that the video is PROGRESSIVE. If the AVI is not PROGRESSIVE then you need to DEINTERLACE it. There should be an option in TMPGEnc for this. Also make sure that the encode is set up to be PROGRESSIVE. There should be an option for that in TMPGEnc as well (I think they use the term NON-INTERLACED which means the same as PROGRESSIVE).

Then use BeSweetGUI and convert the original PAL AVI to AC3 using preset PAL -> NTSC (25.000fps -> 23.976fps)

No! The beauty of the using DGPulldown is that the audio length does NOT need to be adjusted

And then use my TMPGEnc DVD Author to author the DVD using the end resultant m2v and ac3 file ?

Yes. That is correct.

Awesome! I'll definately make sure the video is Progressive. Even if the source isn't progressive, i can very easily encode the mpeg2 using tmpgenc to Progressive.

No! The beauty of the using DGPulldown is that the audio length does NOT need to be adjusted

I'm confused!
Do you mean i use my PAL audio and not convert the audio to NTSC? But then won't the audio be 25.000 fps and video 23.976 fps ?

Thanks a ton!

FulciLives can be forgiven for not having it exactly right, as he hasn't yet used it.

Encode to 25fps, making sure to convert to 720x480 NTSC resolution. Keep both the video and audio at their original 25fps length. Then open the .mpv in DGPulldown, tick the 25->29.97fps preset, and wait. You'll get a 29.97fps .m2v as a result. It's actually something like .mpv.converted, and you rename it to .m2v. The length doesn't change. No reencoding is being done. Flags are being set to output the required 29.97fps from your 25fps .m2v.

Then author any way you like. I've tested with Muxman and DVDAuthorGUI. I haven't used TMPGEnc, so I don't know first hand how it works. But, the developer, neuron2 (Donald Graft), was using TMPGEnc as he developed DGPulldown (but feeding it with an AviSynth script file), so I know it's possible to encode with it. I presume it's possible to author with it, or any other authoring program, because they'll all see an NTSC compliant 29.97fps .m2v.

Ave,

My confusion persists. About the audio. What exactly do i do with the audio? According to you, this is what i understood i need to do:

- Encode my PAL AVI -> PAL M2V 25 FPS PROGRESSIVE 720 X 480 using TMPGENC XPRESS.
- Open encoded M2V in DGPulldown, Choose 25 -> 29.970 FPS
- Convert my PAL AVI to PAL AC3 (25 FPS), No Presets/Conversion
- Use my favorite DVD Authoring tool to Author DVD with the resultant NTSC M2V file and PAL AC3 file.

The last part baffles me. My question remains the same, how can a 25 fps AC3 work with a 29.970 M2V ? Or i'm not understanding something here.

Thanks a ton guys.

The duration of the encoded .m2v doesn't change - that means it is exactly so much frames as before (as PAL). Therefore you should author it with the original audio - the same duration.
For example when you encode 23.976 NTSC you are puldowning the video only to 29.97 - the audio stay in 23.976! They are in synch. Here is the same - the video only is pulldowned to 29.97, the time is the same.
Maybe your confusion come from this "PAL AC3" . There is no such a thing. Try to think it is not PAL.

Ave,

That's a newer concept for me, but that makes sense. Thanks. Today evening i'll go home and try this exact procedure and see what happens.
Thanks a lot guys.. you're awesome!

Hello,

In the past in order to convert PAL to NTSC i've used the (assumefps 23.976) command in my script and then slowed down my audio to match. works pretty good, but I thought I'd try this new technique.

I converted my PAL avi to a PAL mpeg 2 file using DVD2SVCD (settings on AVI2DVD). I then ran the m2v file thru DGPulldown with the default settings and 25fps -> 29.976.

I then loaded the resulting m2v file and the original AC3 audio file (which I demuxed from the original PAL avi file) into TMPGEnc DVD Author to author the DVD. The resulting picture looks great, however the audio is out of sync.

Any ideas?

Thanks!

Encode to 25fps, making sure to convert to 720x480 NTSC resolution.

Ave,

Question.
I used TMPGEnc Xpress for my Video Encodings. When you are encoding a video, it allows you to choose a template first, PAL or NTSC. In this case, i chose PAL as i need the output M2V to be PAL. Then you can choose a resolution using a drop-down menu. The problem is, if you choose PAL as the output, it doesn't give you a 720X480 Resolution option. It gives you 4 or 5 different options, including 720 X 576, but not 720 X 480. How do i define my own custom resolution if i'm encoding to PAL in TMPGEnc Xpress ??

Thanks,
Mickey

Ave,

Can you tell me what i did wrong? I just tried the procedure with everything exactly as you told me.. but the video and audio are out of sync.

I just made a post here: https://www.videohelp.com/forum/viewtopic.php?t=268259

Hi-

I replied in the other thread to which you linked. I encode using CCE giving it AviSynth scripts, and have no idea about what's going wrong with your encodes. My only suggestion was to use an AviSynth script also. I don't know if this guide will help or not. It seems a bit lacking in the encoding details:
