Problems encoding high motion video

[BertL]

Currently I am encoding a movie to SVCD format using TMPGenc v2.54 (Motion search precision: normal; Constant Quality: 80; GOP: standard). The result is very good, with the exception of the high motion scenes. These scenes result in pictures where a lot of colourfull squares are visible. When I viewed them frame by frame, I noticed that always one good frame is followed by two bad frames. I suppose that this has something to do with the GOP structure.
Does anyone have the same experience and a solution for this?
BTW, I tried several settings in TMPGenc including high quality motion search precision, but without noticable difference.

Bump up your Constant Quality Setting

Compressed videos have the tendancy to do this when in high motion like a battle sene (sorry the mis-spell)

SKD_Tech,

I have tried this (CQ 100), but still I had motion blur in the (few) high motion scenes.
I also tried Automatic VBR and 2 pass VBR, but also without success.

Try increasing the bitrate about 50-100 KB more

SKV_Tech,

I am already using a maximum bit rate limit of 2520kbps (tried it with CQ and CQ_VBR) so there is no room for improvement there.

I hoped that there is more to be gained by playing with the GOP structure and the quantization matrix. However yesterday I tried the suggestion from poster "rocknroll" who claimed that he had found the perfect settings for the matrices and GOP, but also did not see a significant improvement there.
Do you have any more suggestions?

Nope sorry. I haven't messed around the the GOP yet. Never really had to. Hope someone else can further help you.
