Render 24p for Video Projection

LarBear360 wrote on 12/10/2018, 11:13 PM

Vegas Pro 16 running on Windows 10. Shooting on Canon T3i at 1080X1920 24fps.

I am putting together video clips to show at a holiday party. Everything was shot 1080 X 1920 24fps. My editing timeline matches my material. I need to render the finished video to be played on a laptop fed to a Panasonic video projector.

My question is whether or not the projector will need 29.97 to look right. I've heard of jerky video playback through projectors due to the 24 fps.

Should I change my timeline properties to 29.97? If not, what render profile would work best?

If your projector was made in the last ten years, there should be no problem with native frame rate 24p. That said, always have a dress rehearsal.

Changing 24 to 29.97 won't smooth any jerkiness. Best to keep native.

Agreed. Stick with the native frame rate of the footage, which is the same frame rate as traditional cinema.

Make yourself a MAGIX AVC/AAC MP4 template that looks like this:

If your source is real 24.000p (not 23.976) then change the frame rate to that.

You could get a very slight quality increase by increasing bit rates but probably not necessary.

My plan is to maintain original frame rate and deliver it that way. I'll render a back-up at 29.97 just in case. The projector is fairly new. From what I can read from the manual, it can manage the 24P.

Last week they replayed a video from last year with the same specs. Camera moves displayed trailing ghost images which is what's scaring me.

Right clicking on the clip and selecting "Disable Resample" always helps me with that "trailing" issue.

It will look worse if you change frame rates. Let it be.

1080x1920?

1080x1920 is vertical video - You will only be able to render this frame size correctly to mp4 format in Vegas using the Main Concept AVC / AAC mp4 or Magix AVC/AAC mp4 codecs. Choose the default internet HD 1080p and in template customize set the frame size to 1080x1920 and the frame rate to 23,976.

If you try to render in sony AVC / MVC format you will get an error because this codec does not support the 1080x1920 frame size.

If there is any jerkiness, the problem is with the projector, not with 24p. For close to a century, 24 fps has been the cinema standard. And cinema projectors avoid any jerkiness by showing the 24 fps film at a pseudo-48 fps rate, where they show each frame of the film twice while cutting the light (with a mask, not by turning it on and off) briefly after each time they show the frame (including the second time).

Sorry if I confused you. Everything was shot at 1080p (1,920 x 1,080) HD recording at 23.976 fps

You should be fine. Disable Resample in your project settings, that will make sure the ghosting isn't coming from Vegas.

Well, today was our day to play the video and as such I delivered 1080p 24 fps. Everything was just fine. No hiccups whatsoever other than the guys who set up the projectors need to learn how to calibrate. I want to thank everyone again for their comments and suggestions.
