Are the trees animated or station. Could you show a sample video of the problem.

flickering gi or flickering AA? big difference. flickering gi is most greatly caused by rendering single frame mode. flickering AA is caused by too sharp a filter combined with low image sampling

THE TREES ARE STATIC. iT IS JUST A FLY THRU CAMERA. iHAVE PROBLEMS WITH THE TRESS AND SOME TIMES WITH THE GRASS MATERIAL. I USE COMBINATION OF IRRADIANCE MAP + LIGHTCACHE
AND IS EXTERIOR SCENE.

I JOPE THIS INFO CAN HELP.

i solved this by using "max subdivs" of 5 instead of 4, in the QMC AA settings.

Mind that for animations, small details like leaves might come out in a range of 1 pixel or close. Raising AA may help, but also think of enabling MB. That would fix lots of the flickering.

@Candelero: Enabling MB?

If its GI flickering try QMC/QMC.

Motion blur - I did a few ads with fly overs of orchards and the only thing that resolved the flickering was motion blur and softer anti-alisers - As nikki mentioned a lot of the leaves were only a pixel big in the background so it was causing a huge amount of pixel creep and flickering.
