SOT: Time warp errors

Many of us have been asking for some of the advanced features in AE and the like to be incorporated in Vegas. Time stretching progressive footage being one of them. John Meyer pointed out although these algorithms can work extremely well they can also be broken.
In my feeble efforts at learning AE I managed to create a good example of both in this



If you watch from the frames labelled 50 to 60 you'll see an example of the thing loosing the plot. In all fairness this was an extreme test slowing down to 25%, I really don't know what I'm doing and apart from this section it works remarkably well.

Just to explain what you're seeing on Youtube. I took the rendered output from AE, dropped it into Vegas, added the TC FX and exported an image sequence as png. I then bought that image sequence back into Vegas at 1 frame per second and exported to mp4 to upload to Youtube. I figured that would make it easier to see, certainly played back at normal speed you could miss the problem if you blinked.

I'd also like to thank Artbeats for the free footage I used in this test.

Bob.

i've been suffering time warp errors for the last five years without the aid of a computer ;-)

You too huh?

At the moment I'm transferring Too Old To Rock 'n' Roll: Too Young to Die!, Songs From A Room and Rockin With Chuck Berry for a mate as these titles are not available on CD. Nice to spend the arvo watching vinyl go 'round and 'round and 'round.
Now where did I hide me bong, anything to make Leonard Cohen bearable.
