Strobing Animation

[Jonathan Ziegler]

Maybe convert to motion JPEG or maybe use the animation codec out of Motion. Can you post a short video? Would like to see it when it strobes and when it doesn’t.

Is field rendering active in the Motion file? I’ve noticed bad strobing issues when field rendering is enabled in a progressive project.

Jonathan,
I’ve tried a Animation codec export out of Motion and a Tiff image sequence and both look the same.

Here is the video:

Strobing Animation

Keep in mind that what you are looking at is small and that the strobing looks worse on a broadcast monitor and even worse on a projector playing blue ray.

Andy,
I’ve tried Field Rendering Off and I can’t seem to stop the strobing. If you look at the video it looks like it has some field interlacing issue but my fields are set to None.

When you exported the tiff sequence, did you see any ghosting in the stills? I wonder if the XDCam EX codec’s compression doesn’t handle that horizontal movement well.

Have you tried rendering out the project (or a small portion of it) in 32-bit float? I did a project once where I had intricate snowflakes in an emitter that looked horrible when rendered out. I ended up having to render them in 32-bit before the animation was smooth.

Out of curiosity, what is the graphic in the background? The newspaper graphic. What is the file format and filesize? In this case, it makes sense to look at everything. Also, what is the font and what type of font is the “Eyeston…” font? Shouldn’t make a difference, but you never know. Maybe try a different graphic or font and see if it happens again.

Could this have to do with the location of the graphic relative to the fields? I seem to remember that this was a tip (place graphics on odd fields if I remember right) from a COW or Macbreak Studio tutorial I watched, but I am not sure if it would apply in this case…just a straw at which to grasp

Andy,
There is no ghosting on the stills. They look very sharp.

I just ran a test to see what 32-bit float would look like. Change it to 32-bit in Motion. Brought the project file in FCP and changed the Sequence Settings Video Processing to “Render all YUV material in high-precision YUV.” It looked better but still had bad strobing.

Sacha,
Thanks, I have had that problem where a clip is the wrong field order and looks bad and using the de-interlace filter in FCP makes it look normal. In this case I have fields set to None in Motion and FCP.

Jonathan,
The graphics in the background are multiple textures blended together. They are .jpeg files and they are 72dpi at something like 2000 pixels by 2000.

I have tried multiple fonts because my original font is skinner. All fonts seem to still strobe. So for the sample I posted online I used something real simple like Arial or something.
