Artifacts on video transcoded from GIF by Elastic Transcoder

Question

I'm trying to transcode GIF to MP4 with H.264 inside using AWS Elastic Transcoder. I noticed strange color artifacts on transcoded video: color stripes on the right.

Original GIF:

Transcoded video screenshot:

I've tried to change settings, even changed output format to WEBM+VP8: same result. My local ffmpeg has no such issue, so I think there is something on ET side.

My MP4 settings, if what:

Do you have any ideas?

Does the artifact in the resulting video move at all, or is it static? — Umopepisdn, Nov 12 '15 at 03:59
@Umopepisdn, not static. Here is transcoded video: https://s3-eu-west-1.amazonaws.com/funcorn-dev/tests/test3.mp4 — Vitaly Chirkov, Nov 12 '15 at 06:32

The width of the image is 381, an odd number that might be getting mishandled during re-scaling.

Try cropping off one pixel on the right to make the image 380x150.
