Problem with Multi Camera editing

[yugoman1]

Trying to edit some footage using 3 camera`s (I often use 2 without problems) I have 3 Canon Camcorders but my latest one has a default frame rate of 60i and the other 2 are 50i. I have a problem with the 60i footage being a little jumpy/jerky when put on to the timeline, have just tried putting this 60i footage into the timeline on its own, but it is still a little jerky. The footage when viewed from my video folder is perfectly ok ??

Is it as simple as Videostudio does not work with 60i ?

Thanks

Yes, VS works with both 50i and 60i. But 60i is associated with NTSC while 50i is obviously enough PAL. And if your Project Properties are set to PAL, then any 60i footage you include in a project will have to lose 10 half frames per second to conform to the Project Properties' 50i. And losing frames will cause the video to look a little jumpy as you describe.

You should perhaps make a small project with, say, a short 50i clip and a short 60i clip, and render it out using the PAL Project Properties (Share > Same As Project Settings) and see if the jumpiness is there in the final product, and if so, whether it is acceptable or not.

This is very interesting Ken.............I have done what you said, mixing the 50i and 60i in a project,and the 60i part after rendering is still jumpy but the 50i is fine. I then changed the project properties to NTSC and set at 60i with the same same 2 camera footage. The results are very good with No visible shake or jerky footage on either frame rates (Not quite sure how this works) But now the rendered file won`t play in windows but will play in VLC Player. I have tried burning an iso file on to a dvd of this footage but then the quality is poor ?

Looks like I have made a mistake buying this 60i camera and need another 50i instead.

Thanks again

What make and model of camera?
Does the camera have options to choose Pal or Ntsc?

Multi Camera Editing sets its timeline frame rate to the same as the first video, that is Camera 1, If that helps.

[yugoman1]

The camera is a Canon Vixia hf100. I am sure it doesn`t have a setting to change Pal/Ntsc. When you say the programme sets it`s rate from the first camera, in Pro x8, is that the first camera that you put into the timeline ? And then the 2nd and 3rd camera`s sit in the next 2 overlay tracks ?

Hi
Apologies for any confusion here
When your title includes Multi Camera editing I had assumed the Tool that came with X9 and X10, MultiCameraEditing
This feature can sync audio then allow us to select sections from up to 6 cameras.

CVSX8 does not have that option so ignore my comment re using camera 1 as frame rate.
If you are working with several cameras you should think of upgrading to a version that has MCE, not sure if the trial x10 has this included, if yes you can give it a go.

OK
Using CVSX8 you can add your camera recordings to different overlay tracks then manually sync the audios, cutting and removing segments from each track to produce a composite project.

First go to Preferences ( F6) and set Show Messages when inserting….
Start a new project
Insert one of your camera recordings to the top track will prompt you to match the properties.
This will set the frame size and rate to your project, so using the pal version will set the frame rate to 25fps.

Adding a ntsc to the overlay track will loose frames, approx. 1 in 5 will be removed to change the video frame rate from 29 .97 to 25.
Unfortunately a price we pay for mixing rates
Adding a Pal to a NTSC timeline and the program will duplicate frames, 1 in 5, changing from 25 to 29.97.

If you now switch to Sound Mixer view the tracks will show the audio wave form and may help in syncing the clips.
Tip---Add a image or colour clip to the beginning of the top track, resize that clip, frame by frame effectively moving the video along the track.

Thank for this info Trevor, I can see now that you fully understand what I have been trying to do. I think it is probably time for me to upgrade to get MCE, and I have also decided to get rid of my 60i camera and get another 50I otherwise I will always be struggling with these different frame rates.

Thanks
Martyn

It seems that you can do only one thing. Transcode from 60i to 50i. I had same problem with a NTSC camera and solved the problem transcoding with Canopus ProCoder3 from 60i to 50i. Same problem with 50p to 50i. Succes

Hi Martyn

Although I do not have the trial installed I viewed some screen shots and it does appear to have MCE
The trial is limited in its functions but should be ok to give the MCE panel a run.

I had to jump in...

If combining two 50i cameras with one 60i camera looks good when you render at 60i, then go ahead and do that. As others said, this will upscale the 50i clips to the 60i rate, which looks smoother than trying to downscale the 60i footage to the 50i rate. Once you have the project rendered in 60i, simply plop it in the timeline and render it at 50i. That should look good.

If your goal is to upload the video to YouTube, then simply upload it as 60i. YouTube will figure out all the other frame rates.
