I am using the NVAPI to create Video DVDs, which works fine.
But one question arose nevertheless: I’ve got MPEG2 files which seem to meet the DVD standard (PAL resolution, 720x576 @ 25 fps). So I hoped that the NVApi wouldn’t take too long to transcode. But what happened was that NV transcoded happily: a 36 minute-video took nearly 2 hours to transcode.
So I am wondering, what takes NV so long to transcode? Which requirements must a video meet in order to be transcoded quickly? What does the DVD standard say?
Thanks a lot.
