Set your project settings to 23.976, and under resample mode, change it to optical flow.

sorry but I just started using Vegas after creating the new project what should I do? can you explain step by step?

Alt enter opens project properties. Set the right framerate and then ressample is towards the bottom (change "disable resample" to "optical flow").

I have the vers. 16 and I see only this

Optical Flow was introduced in Vegas Pro 19.

@Donnje I'm wondering about what you're trying to achieve. I would just import the 25fps video at projectframerate=23.976fps which is an option when you right click the 25fps video in the project media tab.

I have

ITA files 25fps
FULLHD ENG files 23.976fps

I have to mux the ITA audio into the HD ENGL video

I have always used another program and I have to convert the ITA file from 25 to 23.976

So you need only the audio of the ITA file which is at 25fps. The ITA file and the ENG file have the same video content. Does the ITA file and ENG file have the same duration or is the ITA file shorter?

When I understand you right you're trying to replace the English audio of a 23.976fps movie with the Italian audio of the same movie but which is 25fps?

the two videos can be different in duration with cut scenes etc

solved thanks

Of the two most common scenarios for cinema to PAL DVD 25fps, only one may work right for you.

If the movie was sped up from 24 to 25 fps, which was common in the EU before about 2010, you are going to have difficulties muxing PAL to NTSC IVTC in Vegas 16, no matter how you tackle it. The video may have blurred frames or a stutter cadence, the audio may have flanging or echo, or drift. No matter what your reason for wanting to do so, it's hard to unbake that cake. It is what it is.

The good news is, if your PAL DVD is "Soft Telecine," you should be able to extract the pristine 24p video and audio in Handbrake to a file that will play and sound perfect at 24 (23.976) FPS.

To try this, extract the PAL disc it in MakeMKV Beta, encode it in Handbrake with Constant Frame Rate and Same as Source selected on the Video tab, like this. Under US copyright law, you can do this once for your personal use, you may not share or distribute it, or upload it anywhere.

Then, you can put your NTSC rip on the Vegas timeline with the Handbrake encode, and the video and audio should line up reasonably well with no audio drift. You may have to slip the audio track very slightly to give the most pleasing lip sync.

Dei due scenari più comuni per il cinema su DVD PAL a 25 fps, solo uno potrebbe funzionare bene per te.

Se il film è stato accelerato da 24 a 25 fps, cosa comune nell'UE prima del 2010 circa, avrai difficoltà a eseguire il muxing da PAL a NTSC IVTC in Vegas 16, indipendentemente da come lo affronti . Il video potrebbe presentare fotogrammi sfocati o una cadenza balbettante, l'audio potrebbe presentare flanging, eco o deriva. Non importa quale sia il motivo per cui lo desideri, è difficile sformare quella torta. È quello che è.

La buona notizia è che, se il tuo DVD PAL è "Soft Telecine", dovrebbe essere in grado di estrarre il video e l'audio 24p incontaminati in Handbrake in un file che verrà riprodotto e avrà un suono perfetto a 24 (23,976) FPS .

Per provarlo, estrai il disco PAL in MakeMKV Beta, codificalo in Handbrake con Constant Frame Rate e Same as Source selezionato nella scheda Video, in questo modo. Secondo la legge statunitense sul copyright, puoi farlo una volta per uso personale, non puoi condividerlo, distribuirlo o caricarlo ovunque.

Quindi, puoi inserire il tuo rip NTSC sulla timeline di Las Vegas con la codifica Handbrake e il video e l'audio dovrebbero allinearsi ragionevolmente bene senza deriva dell'audio. Potrebbe essere necessario far scorrere leggermente la traccia audio per ottenere l'sincronizzazione labiale più piacevole.

 

Thanks fgreat information, I usually put together spaghetti western movies,
I think these are created in Europe and then slowed down as HD NTSC to 24, do I still have to do the reverse process?

It is actually the other way around. PAL DVDs are sped up to 25fps from 24p film. No matter where they were shot, the majority of cinema film movies are 24.000 FPS.

NTSC DVDs produced in North America are 29.97 interlaced. They can be hard telecine (new interlaced frame rate baked in), or soft telecine (original frame rate flagged as 29.97i).

• The former can be re-encoded and detelecined physically with plenty of hassles and hoops to jump through, and often mediocre results.
• With the latter, since the new frame rate and interlace is faked with metadata flags, a ripper that can ignore these flags can deliver pristine, original 24p with original audio; this has been described above for you.

PAL EU DVDs are 25 FPS. They can be simply sped up slightly, some are soft telecine, and a few made-for-PAL movies were shot at 25p. It is one of the last two scenarios that I hope you have, but they are in the minority.

• If your PAL DVDs are soft telecine, the the process is painless as I described. However, it is unlikely that your spaghetti westerns are that, so you may be stuck with trying to slow down your audio by 1/25, or by using a version of Vegas that has Optical Flow resampling.
• The other method for Vegas 16, using conventional resampling, will give you one blurred frame per second (most local independent TV stations still do this), or one skipped frame per second, causing a slight stutter.

That's about all I know about it, I haven't ripped DVDs for some time, so someone may have another technique.

Thanks now I understand
an you tell me from which version in Vegas has Optical Flow resampling and how should I use it?

I believe it was introduced in version 19, the current version sold by Magix is 21.

To use it, you select it in the project and set your new frame rate in Project Properties, alone or in combination with a deinterlace method.

great found it, what is it for and when exactly should I use it?

It's used for smooth viewing when you change the frame rate of your video. Best of luck!

Actually it generates the extra frames needed to get the new framerate. Optical flow is not always generating perfect frames, it works quite good for generating extra frames for slow motion purpose, but can also generate strange artifacts with fast moving objects.

Don't expect miracles...

so if it is needed for slow motion purposes, from the passage from 25 to 23 it would be better to use the Disable resamble?
