| Hi @all I'm new to the community, so first a big "thank you" to all programmers, testers and forum helpers arround. Thank you for your excellent work! Now here's my question: When I load my mpeg2 television recordings for transcoding to mpeg4 avis, using vdub with mpeg2 plugin, an index file is created first, before I can continue to create a job for later batchprocessing. However I do not perform any editing on the mpeg2 file in vdub, since prior to transcoding I allways have used another program to perform the editing task. Since I seem to observe, that indexing is performed a second time, when I start the job, I wonder if I can suppress the first indexing when creating the job, because in sum this would speed up the batch creation quite a lot. Thanks for help ciao Jochen |

| The first indexing pass is needed since it provides some important information, most notably the length of the video stream. The second indexing pass could be skipped in theory if the first indexing pass were cached, but managing the cache files is a bit involved. |
