Animated GIF to DV video

aldo12xu wrote on 1/13/2005, 6:53 PM

I've been able to take several animated GIFs, edit them in Vegas 4 and create one continuous video. In the preview monitor the motion and quality is identical to what the GIFs looked like on the net. However, when I render the project to a wmv file or an avi file, I get this ghost/morphing look to the motion. From searching this forum, I get the impression that vegas is creating frames inbetween the original GIF frames. That is, I'm going from, say, 10 fps for the original GIFs to 29 fps for the avi file.

Any ideas how I can render the GIFs without that motion effect and still get DV quality video?

Thanks in advance,
Aldo.

(I'm using Vegas 4.0. I added some video fx, cropping and forced sampling to some the GIFs)

You can't.
Vegas has to insert frames, as DV is either 29.97 or 25.00 frames per second. You can render a 10 fps avi, but that won't print to tape, and if you make a DVD, it's gonna be 29.97 or 25.00.
You could render to an MPEG 2 file or an MPEG 1 file keeping it 10 frames, but you're still not going to get it out onto anything.
Build your gifs with more frames, at least 15 for best results.
If the frame size of your gif isn't divisible by standard DV frame size, you might also try supersampling, but you'll still be inserting frames and getting interpolated movement, resulting in some blur from the new frames.

What I have done for some training videos with low frame rates was to convert the timeline to 23.976 and then use a lower bitrate when encoding. I have managed to get near 8 hours of video on DVD with a source of 5-10 fps.

Thanks for the quick reply guys. I think I'll extract the individual frames from the animated GIFs and just create a fast slide show type presentation instead.

Forcing resampling is exactly the wrong thing to do. Instead, you want to disable resampling. This will force Vegas to duplicate frames to fill out the new frame rate rather than interpolating.
