Examples of Jitter Removed From Videos

This was not easy. Let's just get that part straight right away.

It was time-intensive too. I probably spent 5 hours testing the settings. The video themselves took about 30 hours worth of encoding time total per episode, and there were about 4-5 encode passes (each one had different settings, to attack part of the problem).

These two videos were suffering different problems. The first one (16) was a more basic issue. The second one (20) was faced with compounded problems. I removed 100% of the jitter from 16 and about 75% from 20.

Right-click, save as to your hard drive or desktop, don't try to watch them live off the server in a browser, it won't work!

Software used was TMPGEnc and VirtualDub. There was a mix of deinterlacing methods, cropping, edge correction on a negative axis, deshake filtering, and color corrections.

Sample20 was heavily filtered.
Sample16 took about half the work and testing of 20.

The trade-off here is we get slightly softer video, but at least it's not shaking and moving around. It can actually be enjoyed to some degree.

Ideally jitter is prevented at the analog level, using the earliest generation recordings possible. The way you do this is to use a good VCR and a separate TBC. I actaully have a good TBC and VCR, and the tapes were early generation, borrowed from another trader. But these were in shabby condition even on the tapes, even after analog filtering.
