I tried to search for similar issues, I have not found one that combines both. What happens:
- I open an AVI file that has no errors into it (I checked via "scan video stream for errors"). Video is H.264 1280x720, 30.000 fps, audio is reported using Microsoft ADPCM codec, 44 KHz mono; the video is generated by a DVR and plays well on anything - the DVR, computers, phones
- I navigate via the bottom slider to a point in the movie; it works well. I snap to a keyframe or not, there is no difference in what comes next.
- I select that point as Selection start or Selection end (there is no difference)
- I navigate again to a different point. The image displayed on the screen does not change, the previously selected point is still displayed. Snap to keyframe or not - no difference.
- I "Save as AVI" with Full processing or Direct stream copy on video, there is no difference: the result has audio, but not video. Sometimes after ~ 10 seconds in the resulted AVI I get the selected image as video, but static
So there is a navigation problem, a selection and an encoding one. The system is a fairly recent installed Windows 8.1 update 1 x64 with all updates to date, original version from MSDN (I have a developer subscription). The codec installed is x264 vfw 32 bit version 38_2274_bm_36885, VirtualDub 1.10.4 32 bit. |

After navigating to a new frame, do you see "loading frame XXX..." in the status bar? There may be a long wait before the selected frame is finally shown.
Failing that, try the FFmpeg input driver. You will have to override the default AVI input driver and force the use of the FFmpeg driver when opening the file (as explained in the link)
Even though you gave an excellent file summary, a MediaInfo report may turn up something useful. |

No message like "loading frame ...". Also when I move the slider before selecting a start or end point it works very fast, the navigation problem appears only after I select a point.

Later info: the navigation problem stops if I move to the beginning of the movie after selecting an end point - I can select anything else after that and the frame is displayed. Step by step, how I reproduce it:
- open the AVI
- move the slider to frame 11220 (or some other, it's the same)
- select "Set selection end". The message in status bar is "Selecting frames 0-11220 (11220 frames)"
- wherever I click on the navigation bar or wherever I drag and drop it, this message stays the same until I click to start of movie; the status bar clears and everything works fine
- then I select a different frame as Set selection start (frame around 11.000). The navigation breaks until I move to the begining of the movie, then the bar clears and it works fine
Even if the navigation is fixed after the selection, saving the selected part of the movie does not have video. I am actually using VirtualDub to crop the movie, nothing else. |

Maybe my answer has nothing to do with it, but you never know...
When you look into VirtualDub View-menu, is there a check mark before "Input video pane" and "Output video pane" ?
If not, there will be no refresh of images in these panes.
And, if you say that the resulting AVI has no video in it, do you verify this by opening it in VirtualDub or do you really play that video via a player (like Windows Media Player, VLC or something else) ?

Sometimes direct copy can help by selecting direct copy for both video and audio and save as a new avi and see if the new saved video is better. To do so will need use of another decoder plugin such as the one raffriff42 has mention FFmpeg input driver. which can load near if not all that ffmpeg can load. Another one to use is fcchandlers Quicktime plugin decoder for virtualdub. You don't need the actual ffmpeg or quicktime to be installed to use either of these plugin decoders with virtualdub
Check video stream to me only seems to work with uncompressed avi video, unsure if supports error reported for compressed avi or not as yet ?
If so can load the video as uncompressed avi using Avisynth via a script so make video load as uncompressed in virtualdub. Could even use avisynth instead of above decoder plugins to load the video but would need a script to do so
Virtualdub frameserver could be used to do the same by running two instances of virtualdub at same time to do so. Virtualdub help [F1] gives more details of use of its frameserver |
