hi again, i have done many tests, first i tried on another computer, same video file, same splits and get the same king of results, svrt2 has longer rending time than nosvrt. I am convinced that this is related to the number of split and video data... may be frame lost at capture, etc...
I did a test with aquarium.mpg and found similar behavior but not as worst than my original video file. I observe that "estimated time" takes long time to be displayed in such case, 5,10, 15 minutes, sometimes hours for my original video with different number of split.
here a test case with aquarium.mpg
1) produce aquarium.mpg mpegII file
2) do a long aquarium.mpg file repeating new aquarium.mpeg2 , say 01:00:54.14 total time . Using svrt2 for creating long aquarium.mpeg2 is fast, in fact it fly....
3) bring the new long aquarium.mpeg2 in timeline, do 20 splits on it, then produce mpeg2.
4) at this point you should note that "estimated time" take a bit long to appear, and if you try to abort, it will not. if you do abort later, after estimated time appear, it will abort.
running this on my core2 laptop, give me 23:14 minutes for svrt2 on, 22:20 svrt off, quite similar...but very far to the 10 to 20 times faster performance
