Hi

. . . . The 30fps is jerky when imported to 25fps movie . . .

This is a result of 'pulldown' where frames are in effect 'dropped' from the video to bring the number of frames per second down to 25 fps.

You get a similar effect when you try to go the other way as well ie 25 fps up to 30 fps, however in this case extra frames are added by repeating certain frames at regular intervals to achieve 30 in 1 second.

The jerkiness is usually seen at its worst when panning from right to left at a resonable speed or there is movement in the shot. The effect can be mimimised by slow panning - however this is not a;ways practical.

I have been plagued with, and experimented in fixing, this problem of mixing framerates for over 2 years with no truly satisfactory solution.

My final step was to replace the 30 fps sportscam with one that has multiple fps settings including 25fps.

Thanks you two, but I've tried all the different combinations and I just don't understand as there must be software to convert UK Pal videos to USA NTSC and vis versa (i.e. 25 and 30 (29.97) fps) and to convert film rate of 24 fps, all without jerkeness. So does anyone know of any good suitable software? or is buying another camcorder the answer?

Hi

. . . . So does anyone know of any good suitable software? or is buying another camcorder the answer? . . . .

I think I have already answered this in my original post, however to expand it a bit more -

I tried every frame rate converter I could find over the 2years + with no satisfactory success. 

Other tests including upping the 30fps  framerate to 150 fps with new frame calculation, exporting then importing the 150fps video and then reducing down to 25 fps. 

The theory was that with 5x as many frames calculated the reduction to 25 fps would use every 6th frame for the 25fps video - however it still exhibited the jerkiness.

I took the route of getting a new camera (Sony AS30) which also gave me many other options such as WiFi control, GPS, still images, interval timing for still images ie timelapse, slow mo, ability to run on external power via USB, underwater housing, dual angle lens and much more.

Well thanks again, but as I said  before and after more enqiries, there must be some software or some way that usa and uk cameras can work together. Maybe Magix has the answer?

Apart from the inherent technical issue that John has fully described, I think the reason you're not getting any further help is that your question is confusing and you've changed it twice.

My interpretation of your three questions is as follows:

Q1 (2014-02-18 at 10:32 AM): How can I combine 25 and 30fps material in the same Magix edit pro 2013 project. The 30fps is jerky when imported to 25fps movie

Q2 (2014-02-19 12:01 PM): Is there some software to convert UK Pal videos to USA NTSC and vis versa (i.e. 25 and 30 (29.97) fps) and to convert film rate of 24 fps, all without jerkeness?

Q3 (2014-02-26 12:29 AM ): Is there some software or some way that usa and uk cameras can work together?

In addition, you've provided very few details.

What product and exact version and patch level are you using? What is your computer spec?

Assuming your specific problem remains the original one, you should create a project containing 2 or 3 short movie clips that behaves in the jerky manner. At the very least then provide:

1. Full details of your project settings and export settings.

2. Details of each file, using MediaInfo or GSpot, including their respective fps.

3. An upload of the exported result showing the jerkiness.

Repeat that for a project fps of both 25 and 29.97.

Better still, make a small, non-confidential project exhibiting the problem and use File > Backup > Copy project and media into a folder, zip it up and upload it so that we can see what you mean and maybe try to reproduce it.

Also, did you read this sticky?

You ask: "Maybe Magix has the answer?"

Have you asked them? This is a user forum and Magix rarely contribute to it. You should use the formal ticketed support form via this link (or your country equivalent):
