I need a software where I can visually see the film divided into 18 or 24 fps.

Do you think Audacity can do that?

To make it clearer, the reason I am asking I have several digest and mini features German releases of English film that I'd like to put back to english dub.

Some members here are transferring (telecine) the 8mm film to MP4 (or sort of) and then edit the english version of the same film taken from DVD.

But since I don't have time to telecine, I am thinking to put the DVD version to a software and divide the picture into 24 fps. With an 8mm viewer or editor I will synchronize the DVD version frame by frame (by cutting the frames that are not in the 8mm version). At the end I will have the exact same cut between DVD and super 8mm.

Do you think it will work?

Your opinion please.

Well Winbert to answer your first question. What I believe you are looking for is a program that will output an image sequence of a video file. The answer is yes. I use VirtualDub 2 https://sourceforge.net/projects/vdfiltermod/. This is an updated version of VirtualDub that accepts formats other that just AVI as input. You input the video file...change the framerate to 24 or 18 then export the file as an image sequence. You can choose the image format such as .png, .jpg, or .tif. Instead of outputting to indivdidual files you can also just advance the video file one frame at a time within the VirtualDub2 viewer.

Now the question is....Do you really want to do this? I'd highly discourage it. Just video-wise...as an example. A 14 min video at 18fps will output to approximately 16,000 frames. The movement from frame to frame is so visually minuscule that the chances of you syncing it up with a film viewer would be near to impossible... not too mention would take hundreds of hours. Much more time than it would take to telecine.

Also audio is based on time and sample rate that is measured in kilohertz. Think of it as separate from video which is based on frames. Audio works for any frame rate. Two minutes of audio from 2 minutes of video will match regardless of frames per second. This means that if you are re-recording the audio that your projector would have to be running at a consistantly perfect framerate ... which most don't.

Thanks Janice, I was not aware those details.

So 16,000 frames would take so much my hard drive which I am now running with an old Wondows 7 version. The computer will die soon the 16,000 frames are uploaded... [Big Grin]

So I supposed I need back to the telecine route then.

cheers,

In a pinch, do you intend to re-dub your German version Super8 to English?

If yes, that's totally possible. I believe several members here had done that before. But that's not an easy task of course especially if you need frame-accurate dubbing. [Roll Eyes]

A crystal-sync projector such as Elmo GS1200 would be a must then.
