what the heck? bizarre altering frame rate...

[EddyH]

ok, so i have a divx movie... and a friend wishes to watch this movie... but they thought i had the dvd instead, and their PC isnt fast enough. so i offer to make VCDs that their DVD player can handle, which they're cool with as they have four or five already, albeit commercial ones another of their friends brought over from the phillipines.

it all goes well, barring an odd, probably download-based scene-repeating jump near the start of the divx, which can be excised pretty easily next time i attempt it. that is, until i make the second disc. the file presents as a pal-happy 25fps divx, all the way through, and virtual dub seems to back that up showing 25 frames ticking by every second when i play through. TMPGEnc doesn't agree though. It initially saw the film as 25fps, and that came out perfectly smooth, but when i used source range to set up the second half encode, it decided it was now 30fps, no matter where i cut it... and although I reset that to 25fps, the resulting mpg (which reported as 25fps, as did the first) was horribly jerky, like.. well.. like it was losing a frame five or six times a second

the only response to something like this of course, is "What the Hell?!?!"

Anyone know just what the blue blazes is going on? The audio stayed in perfect sync and didnt seem to have been slowed or speeded by such a considerable degree in either case, neither did the on-screen action.

needless to say, in the end, we found a decent film on the television to watch instead... but this is still tickling my curiosity.

try to frameserve the video when encoding it, i had the same problem and after frameserving it tmpegnc recognized the file at ther right frame rate in source mode. Hope this helps
