i have encoded the video using x264 and decoded. in the decoded video i see jerks in the display.can anyone let me know what is going worng?
initially i had pixelation also then i increased the deblocking filter strength to -4,-4 so pixelation is reduced but still jerks are there. what could be wrong?

Pixelation is from a wrongly configured DECODER, jerking can be from using a source with DirectShowSource() instead of a frame accurate source decoder ...

Without any detail, specs, OS, method of encoding used, decoders used, or any real detail from you, that's as specific as I can get ...
