View Full Version : TGA causing flickering ? :/

Hello everybody.
I'm doing some animations for a client that needs avi files with interlace. I rendered all my animations from 3dsMax, saved as TGA sequence and imported to AfterFX. Then rendered it as avi with interlace. The client says that on some parts of the animation he can see flickering (on a T), supposedly because I used TGA (or any other format without interlace).
Any ideas what could be causing this ? Am I doing something wrong here?

Interlace or not is never a format issue it's a rendering issue.
I would rather render interlaced from 3dsmax, adding interlace on full frame animation in AE won't do anything.

AE does recognize edges and such and adds interlaces though.

I know that would probably be less problematic, but is it impossible to get good, smooth video with interlace from an image sequence that has no interlace?
Currently rendering this to a different format is not an option for me as I have little time and most sequences use tga alpha channel for transparency.

Dumb question here, but is the interlaced video being played on a computer? It's not unusual to see artifacts from interlaced video on a computer monitor.

Nope.
Also AFAIK and as far as I could get some expertise opinion that is not a problem with using a sequence of files. If the frame rate is high enough (at least double the output video) everything should be OK.

You mentioned: ..." The client says that on some parts of the animation he can see flickering (on a T) ... "

Is the "on a T" to be taken literally... as in a Letter T? If it is, perhaps the choice of typeface is the issue. Depending on how big it is on screen as well as if the serifs are thin or not, this might be the cause of the problem.

Otherwise, can you post a screen shot so we can see the problem?
