Movement footage shakey/blurry after render

[John Rofrano]

> My movie is set up as follows

I’m not sure what “my movie is set up” means…

What format is you source footage?

What camera?

What are your project properties?

What are your render properties?

It sure sound like an interlace problem which shouldn’t happen if everything is progressive.

It could be rolling shutter. Camera’s with CMOS sensors are susceptible to this phenomenon, which is most noticeable when panning across verticals or when you are following action. It shows up as a watery effect on verticals or strobing effect on fast movement.

You can do a Google search on rolling shutter and find plenty of discussion on it.

If your issue is indeed a rolling shutter problem, I have been unable to correct it on the timeline in POST. I have found turning off image stabilisation when the camera is mounted on a tripod seems to help a bit… . That probably is of no help to you for your current project… .

Sorry, I meant my project properties.

What format is you source footage?

It was originally a vob file that I converted to mpeg I believe.

What camera?

The camera is fairly old. Its one of those Sony Mini DVD camcorders. When I finalize the dvd and play it back in a player UNEDITED, there is no motion blur. Only after I render and play the edited Version.

What are your project properties?

Project properties were set in two different settings.

1- HDV 720-30p (1280×720, 29.970 fps)
Field order: progressive scan
Pixel format: 8bit
Full resolution rendering quality: Best
Motion blur type: guassian
Deinterlaced method: none

2- NTSC widescreen DVD 720×480
Default settings

What are your render properties?

I am not exactly sure since I am not at my computer right now. I will get home and double check.

It sure sound like an interlace problem which shouldn’t happen if everything is progressive.

I hope its just a simple mistake on my part which i am missing. Like i said the video recorded fine, its once I edit and render where it causes this awful motion blur/strobe effect.

Thanks for all your help.

I have one last questions and that is… what are you trying to do?

If I understand correctly, you have an MPEG file that you got from a Standard Definition DVD which contains interlaced video. You are loading it into a Hi Definition project that is progressive scan. You are then rendering it to a Standard Definition DVD that is interlaced. This flip-flopping between interlaced and progressive is what’s causing your problem. I’m not even sure why you are using HD at all.

My advice is to set your project properties to match both your source footage and output format which is NTSC DV Widescreen. Then edit and render to NTSC DVD Widescreen and everything should look fine. Don’t change any of the default settings for the project or render.

Hello thanks for your response.

Yes my second project properties settings was set to NTSC DVD widescreen. I then rendered it as MPEG-2 with audio but I still noticed some blurryness.

I will try everything all again when I get home hopefully it will work out.

Yeah my first setting was totally wrong (1280×720).

Thanks.

I’m Having the same problem. Except I’m using Platinum 9, and i don’t have a motion blur option. But yeah i agree – This does hurt your eyes and it looks terrible. It defeats the purpose of “HD” videos. It like depletes the smoothness of the videos clips and its really irritating.
