VirtualDub 1.9.6 is now available for download. This is a stable fix-only release addressing several bugs and also some regressions introduced along the 1.9.x code line. The main intent is to try to fix all of the issues that are preventing people from migrating from 1.8.x to 1.9.x.
The current plan is to release at least one more bug-fix only release (1.9.7), and after that, I have no idea. I have some relatively largish changes pending in another code line, but at this point I don't think I'm going to want to release it as 1.9.8, in case I need to release another fix-only release in the interim... which leads to a problem because I've run out of mid-level version numbers. I'm not going to start a 1.10.x line, because I learned the hard way that everyone reads it as a decimal and thinks .10 < .9. What I should have done was inserted a leading zero so that I'd be at 1.09 instead. I could just jump to 2.0.x instead, but that seems kind of lame since I'm unlikely to have the kinds of changes that would warrant a 2.0 release. Then again, the last time I thought I was going make version 2 a big upgrade I ended up screwing up the code line so badly I had to pull a Vista and restart from the 1.4 code base, so maybe I should just bump the version number.
Maybe I should just be lazy and use build numbers.
Anyway, here's the change log for this release:

VirtualDub 1.9.7 is now out, and is another stable release containing only bug fixes for reported problems.
The most important fix in this version is a change to the code that reads AVI hierarchical indices. Normally these indices are only two levels deep, with a master index in the header and subindex blocks covering no more than 4GB. If you're wondering whether deeper indices are possible, the answer is an emphatic yes. It turns out there's at least one hardware/software editing solution that produces AVI files with deep index trees, because it links all of the subindex blocks with internal nodes arranged in a degenerate tree. The trace I received of a 46GB capture showed a tree more than 20 levels deep. This was causing a crash in 1.9.6 because of some changes that I made a while back to fix slow index reading speed problems over a network; in doing so I had increased the size of an I/O buffer on the stack and this was causing a stack overflow. 1.9.7's index read routine has much lower stack usage and should be able to read AVI files with deeply nested indices again.
I've been spending some time in the dev branch trying to add new raw video formats to the blitter library, and I think I've spent so much time in Scilab staring at YCbCr matrices that they're all starting to blur together. Nevertheless, the blitter autotests are finally passing again (although at a slower rate, since the test matrix is now 37x37 instead of 17x17), and I think I'm finally making some progress here. The next step would be to add support for the new formats to the video source and display paths, which should finally get some of these new formats into a usable path. Some optimization would be needed after that since all of the new formats are currently leveraging a lot of unvectorized C++ code, but we'll see how that turns out.

In version 2.5, I changed the way the size of the initial block was calculated, to make it more consistent.
As a side effect, this meant that for certain settings (such as the default ones) and certain video sizes (such as interlaced 720x576 and interlaced 720x480), pass 1 would run a lot slower than before.
After some testing, I have now made another adjustment to this initial block size to speed things up. If you feel that this version is less reliable than versions 2.5 and 2.6, please let me know. (test-14) Fixed open/save file dialog regression.

Read more under the 'Detect scenes' setting above. For skipped frames that are not new scenes, Deshaker will interpolate motion values in pass 2.
Default percentage for skipping frames was increased from 5% to 8% because Deshaker now handles skipped frames better.
Skipped frames will now be marked "skipped" in the logfile, and such lines won't have any values anymore. Missing frames in the logfile will also be treated like they are skipped, but they will not become new scenes as before.
Default value for initial search range was decreased from 40% to 30%, because an unnecessarily high value can have a slightly negative impact on the new scene detector, and 40% is way more than you need for most videos.
The option to do the matching in pass 1 in grayscale mode was removed because of the new scene detector.
Removed the option to discard dark pixels and replaced it with a better way to ignore noise. Read more under the 'Discard motion of blocks that have maximum pixel value difference less than X' setting above.
Smoothness for zoom stabilization and adaptive zoom are now controlled separately, so the usual zoom smoothness setting now controls only stabilization of zooming in the clip. As for controlling adaptive zoom smoothness, read more under the 'Adaptive zoom smoothness' setting above.
Adaptive zoom now uses a new smoothing algorithm, so it will look slightly different (better?). Its smoothness values are only approximately comparable to before in how smooth it gets.
Added a setting for controlling the amount (amplitude) of adaptive zoom, in percent. Read more under the 'Adaptive zoom amount' setting above.
Added a new edge compensation option Adaptive zoom full, which is similar to the usual Adaptive zoom, except that this one will remove borders completely (if adaptive zoom amount is 100%). Kind of like Adaptive+fixed, but doesn't add as much zoom in less shaky sections. Read more under the 'Edge compensation' setting above.
The original Adaptive zoom option changed name to Adaptive zoom average.
Removed the somewhat confusing edge compensation options Adaptive zoom only and Adaptive+fixed only. You can now get the same effect by using another adaptive zoom option and setting the zoom motion smoothness to 0. (When loading old settings files which used these removed options, Deshaker will automatically choose settings that work similarly as before.)
All edge compensation options (except None) now checks for rolling shutter distortions too. (Those distortions usually require some extra slight zoom to completely get rid of borders.)
Zoom stabilization and adaptive zoom no longer spill over scene changes. Previously, that would happen when edge compensation was used.
Made a tiny adjustment to amount of adaptive zoom, to make zoom factor exactly 1 for a still video sequence, to avoid degrading the quality due to resampling in such cases.
The very last frame (and any frame that has a skipped frame after it) of a rolling shutter video clip will now be compensated for rolling shutter distortion too, but a little less accurately. Previously, no compensation was made for those single frames.
Added two video output modes for pass 1, which make the motion vectors longer, by 2x or 5x. Read more under the 'Video output' setting above.
Added buttons in the configuration dialog to open or delete the current log file, and also to open the current log file folder. (Deleting the log file can be useful if you use the Append to file option, but want to get rid of old garbage (prior to running pass 1) that may otherwise influence the stabilization.)
Deshaker now uses less memory during pass 1 (which should allow for processing larger images/frames).
Deshaker will now try a little harder (but not too hard) to keep tracking the same object(s) if Remember discarded areas to next frame is enabled, even when frames become skipped due to too few ok blocks.
Added a somewhat hidden feature to make Deshaker forget the remembered discarded areas for current frame if you click once (or twice) on the Remember discarded areas to next frame checkbox.
While the Deep analysis algorithm is pretty good, it does ignore any remembered discarded areas from previous frame, which is usually bad. So now, Deep analysis will only be used whenever we're ignoring remembered areas from previous frame, either because remembering is disabled, or because we get way too few ok blocks.
The log file now looks somewhat different (although pass 2 can still read the old format). Each tabbed column is now reserved for a single thing. And a scene detection value and percent ok blocks are now written to the log file, after the comment character "#". And the "new_scene" keyword is now called "n_scene" (to make the log file look nice in notepad :)
Improved error handling.
Other minor changes and fixes.
