Working my way through authoring 20 DVDs and hit a real oddity. The encoded mpeg-2 file is 1:45:00:00 on the DVDA T/L but that's impossible, I encoded at 6Mb/sec average, and the mpeg-2 file is only around 3GB.
Now DVDA was going real funky trying to play this video so I opened it in Vegas, just the mpeg-2 portion, and Vegas also sees it as 105 minutes long. Now the last frame of real vision was black and yip, I've got 40 odd minutes of black on the T/L but Vegas also goes nuts trying to play this. Tried PowerDVD and it plays it fine upto where the original vision ended and then it too goes wobbly.
So I go back the the original .Veg file. And there it was, an errant marker way past the end of the actual video, at, you guessed it, 105 minutes. Now I had told Vegas to include markers in the encode, obviously that's what spun the process out, both the ac3 and the mpeg-2 file think they run for 105 minutes, yet clearly judging by the file size that's impossible.
Unless perhaps somehow the encoder just produced an extra 40 odd minutes of repeat frames?
No real sweat, just fixed the original .veg and re-encode but still, worth noting, check for markers way past the end of vision else you can get some wierd results.
