Why Mpeg video flickers on camera motion?

[Vishal0011]

I've seen it all around, and I watch those flickers without a clue. I've asked several pros around, and they say its due to bad compression. One of my pro friend said, he knows a guru that compresses raw avi files into mpeg 2 without this flicker problem at all! I still have no clue why the hell these flickers come up in mpeg videos only in the scenes where you see the camera moving, slow or fast.

These aren't those flickers that evolve at the contrast edges due to interlacing-deinterlacing issues... In this case, the flicker is sceen across the whole screen!

Whenever the camera moves, from top to bottom, from left to right, from here to there... these scenes when seen in the compressed mpeg files, show that flicker... the jaggy flicker.. And I don't know how can you rectify that jagged video!

Record a video using your digital camera and it saves the video on its flash card in mpeg compression... Transfer that video to your PC and play it, and here you find that flicker present on all scenes where your camera was moving... Record a raw uncomressed avi using your handycam or a Professional Camcorder, transfer it on your system, encode it in mpeg, and now you get those flickers on camera moves....

Here I post this message with my true frustration coming out for these flickers... I'm sure the whole world out there is experiencing the same... For God's sake can anyone out there save me and everybody from these flickers? Experts, please help, and please tell us why these camera-motion screen-flickers are there in mpeg compressed videos... and how to get rid of them?

Please please help!

Thanks a million in advance.

Reversed fields. If your source is Bottom Field First and the MPEG2 is encoded at Top Field First, you always get exactly what you described. Run your source footage through GSpot and and see if it is TFF or BFF. Set your MPEG encoder to the same field setting as the source.

You shouldn't have any problems playing MPEG 2 video on any modern computer. What player are you using? What CPU? What graphics card? Get the two MPEG 2 videos from this post:

Any problems playing them? If so, what are the symptoms?
