18 f/s tot 25 f/s

[Studio Brandaris]

If I want to edit a digitized Super-8 film with an image size of 1920 x 1080 and a frame rate: 18.00 f/s in a HD project of 1920 x 1080 and a frame rate of 25 f/s, how can I best convert this film without too many artifacts. Premiere does not have the option of 18 f/s. I only see 23.98 and 15 f/s. First converting to Apple Prores 4444 XQ, 25 f/s gives a reasonable result, but there are still jerky movements and regular artifacts in the image

What happens if you create a new Sequence in Premiere Pro @ 1920x1080, 25 fps and just drop your 18 fps footage there? If it looks good, edit the footage in a 25 fps timeline and export to 25 fps when done. Try it.

Then I get artifacts with a lot of movement

Yes, 18 fps is tricky with Premiere Pro.

As you've probably noticed, if you drag and drop a source 1080p18 ProRes 4444 XQ clip onto the New Item icon or to an empty Timeline panel to create a Sequence based on the clip settings, you'll get a Sequence with an 18 fps Time Base.  Still, it will not hold 18 fps when exported (the resulting file winds up at 15 fps).

Go ahead and edit in Premiere Pro to the point of getting to a fine cut, but hold off on any effects and color correction.  Send the resulting Sequence to After Effects for finishing and export using the After Effects Render Queue to get a 1080p18 ProRes 4444 HQ full-resolution edited movie.

Then use Shutter Encoder to encode to H264 or H265 if needed to maintain the 18 fps.

@Warren Heaton , what would be the best frame-rate, if you can choose when transfering 8 and Super 8mm?

[Studio Brandaris]

Thanks Warren,
I will try it the way you suggested.

@Warren Heaton In earlier versions of Premiere one could export to 18 fps (match sequence settings) AME has changed that.

What I have done is rewrap the mp4 to mov in Shutter Encoder. (Premiere does not handle the mp4 very well).

Drop this 18 fps in a 25 fps timeline, no edits or effects.

Exported to Prores 422 HQ with frame blending on.

No artifacts.

@Studio Brandaris Tried your Vietnam film.

Hi Ann,
It's still about this same movie. I followed your advice at the time to convert the MP4 footage to Prores 422 HQ 25 f/s. Still, the clips with movement continued to give me problems. Stretching to fit the image to the sound every now and then also caused problems with artifacts. I therefore left the film for a while due to lack of time. Now I want to try if I can keep the good quality of the 18 f/s MP4 movie. I'm going to see if what Warren wrote to me works. Must install AE first. I've never used this. I'll see where I can find the Shutter Encoder.

[Ann Bens]

No you have not done what i have mentioned in my previous post.

You did not rewrap.

This new file is over 30 gig.

I don't know of any free service that will send you this file.

With my Stone Age Internet connection, that's going to take days. The fiber optic cable is already up to my front door, but still needs to be connected.
