fdct done twice for each block. first time during quant calculation, second
during slice encoding. so if we pre-save dct coefficients no need to do fdct
second time.
disadvantages: requires more memory
advantages: improves performance ~4-5%

I seems to be lame as failed to find how to run fate to check prores_ks :(

problem occurs in slice quant estimation and slice encoding.
if slice quant >= MAX_STORED_Q we dont use pre-calculated quant matrices but
generate new:
qmat = ctx->custom_q;
qmat_chroma = ctx->custom_q;
for (i = 0; i < 64; i++) {
qmat[i] = ctx->quant_mat[i] * quant;
, after all we pass qmat/qmat_chroma to function where we
estimate encoded slice size or encode slice:
estimate_slice_plane / encode_slice_plane
I will make new patch with detailed description
