freeware conversion PAL->NTSC

Hello.I need convert PAL dvd to NTSC.Is a digital recording from from a music fest,broadcasted in 2004 in a french channel ,MCM.I don’t wanna convert the menus.Just the video.The Gen/lineage is :Satelite Receiver>HDD>DVDR
Video :720x576,25 fps,8.24 mbps.
Audio:LPCM,48Khz,1536kbps, Audio channels:2

I was trying with Nero vision 4.I am happy with the results
(Although I choosed fast codification.The rest I let like automatic).I made the authoring with GUI for dvdauthor.

I got :
Video : 720x480,30 fps,5.01 mbps
Audio : Dolby Digital,48 Khz,192 kbps,Audio channels:6

,the only problem was that in some parts
where was filmed with that automatic cameras that move of one side to the other,in the edge of the stage.Appear like was deleted some frames,or something like that.I’ll try of get better results with a manual convertion.

I need make that conversion only with freeware.

I know that I must follow this steps:

1) Demux the video and audio streams.(with ReJig or
dvdecrypter in ifo mode)

2) If the video is interlaced, deinterlace it to make it
progressive. If it is already progressive, skip this step.

3) Resize the video to 720x480. (with avisynth)

4) Encode the video to MPEG2 at 25fps progressive.(with CEE)
(the step 3 would be covered with CEE also)

5) Run DGPulldown on the video MPEG2 stream to flag it up to 29.97fps (using the 25fps --> 29.97fps conversion).

6) convert audio from 25fps to 23.976fps with Besweet

7)Mux the audio and video into a program stream, or author a DVD using the audio and video streams.
(I’ll use GUI for dvdauthor.)

I have some questions,please:

-In the step 2:How can I realized if my PAL dvd is interlaced or not? what freeware would deinterlace it? I would leave interlaced?

-Related to the step 4 Please,I can replace CEE for the free encoder QuEnc? Or Exist another option?.I need make that conversion only with freeware.

-Related with the step 4:
I must encode to 23.976fps or 25fps ?

-I need the step 6 really?

Sorry for the storm of questions.
Any help ? thanks in advance

Hi-

6) convert audio from 25fps to 23.976fps with Besweet

If you're using the DGPulldown way, you don't have to stretch the audio. Leave it untouched, or reencode it to AC3, but without changing the length.

You have to find out if it's interlaced or not. The only way to do that is to examine the frames carefully.

I need make that conversion only with freeware.

They're giving away CCE now?

-In the step 2:How can I realized if my PAL dvd is interlaced or not? what freeware would deinterlace it? I would leave interlaced?

You look at the individual frames, without any processing. For example, many players will deinterlace it. They're no good to check for interlacing. If you decide it has to be deinterlaced, then you use an AviSynth deinterlacer, such as LeakKernelDeint or TDeint. If you plan on using DGPulldown, it has to be progressive. You can apply pulldown only to progressive sources.

-Related with the step 4:
I must encode to 23.976fps or 25fps ?

It depends on what you decide to do. If you decide to encode for 23.976fps, it has to be progressive.

For the DGPulldown method of PAL->NTSC, encode to 25fps, i.e., do not change the frame rate; that will be done by DGPulldown.

Thanks for the replies.

Manono : I am thinking in use the free QuEnc instead CEE.
In this link

tells one way for know if one vid is interlaced.
please,how looks an interlaced artifact ?

Neuron2:You are the author of DGPulldown ? I recognize your username.
in that case,congratullations...very useful tool.Thanks for the hint.

That was a big thread to which you linked so I didn't read it. But if you're following FulciLives' advice, then you're in good hands. And forgive me if I contradict anything he says.

OK, but I might recommend the HCEnc instead of QUEnc. It takes only AviSynth script files and D2Vs, which should be OK with you.

His thread is over 2 years old, which in the AviSynth world is a long time. For example, that interlaced script, while OK in principle, requires Ver 2.08, which isn't necessary now, as you can use LeakKernelBob or TDeint(Mode=1) as the doublerate deinterlacer, instead of SmoothDeinterlace. I didn't find the place where he actually said how to determine if it's interlaced. But I didn't look very hard either. So, what does interlacing look like:

It has lots of pics of interlaced video, but some of that page is nonsense, so don't follow the advice blindly.

And yes, he's that neuron2. He developed not only DGPulldown, but many, many, other tools and filters which many of us use every day:

Very Thanks manono.This is the first time that I heard about that HCEnc.I am downloading that tool.
Thanks also for the link,is interesting anyways.That interlaced pictures would help me a lot.
At least for understand better the situation.

I don't realized that that thread was posted almost 3 years ago ! Silly Me !!!

A similar thread exist:
https://forum.videohelp.com/viewtopic.php?t=160433&start=0&postdays=0&postorder=asc&hig...ec136c7ca677b8

for anyone who would be interested in that subject...but,manono,like you told,some scripts aren't neccesary now.

I am a beginner in the PAL->NTSC subject ...Very Thanks for the help!!!
