DeShaker Clip will not render in V7.0e

I have a problem with a clip that plays on the preview but won't render. Shot with HV20, DeShaker'ized, and CTRL-DRAG speedup.
When I render out, that segment is black.

Here are details, none of which I am sure matters.

1. Shot with HV20, HDV 24P (60i with pulldown)
2. Original clilp plays and renders.
3. CTRL-DRAG of original clip plays and renders.
4. DeShake original with Vegas .js script.
5. DeShake take plays and renders.
6. CTRL-DRAG of DeShake plays in preview, but renders black.
7. Render DeShake to new track.
8. New Track plays and renders.
9. CTRL-DRAG of New Track plays and renders.

Looks like a V7.0e bug since it plays on preview, but renders black. Work-around is tedious, time consuming with all these renders.

Any clue what's wrong - maybe it is just me?

Well if it is you . .it is YOU and me too!!

SD here.

JS Deshake.

Ctrl+SQUEEZE for accel.

Renders to BLACK

Now, I don't even NEED to render, it still plays black in Preview?

I never tried this. Good catch!!

What IS in there that Vegas can't see on SQUEEZE? On stretch - going slower - I CAN do it 'cept it reduces the overal Aspect ratio?

Also tried SubClip .. same results as as you.

It only happens when I squeeze the AVI from DeShaker - though it still shows up in the preview. I remember the aspect ratio as well.

I got the idea from my recent hoiday in Europe. Took a riverboat tourist thing and let camcorder run.Want todeshake and squeeze down to about 5minutes. Works fine as long as I render to new track before squeezing.

I only noticed the problem when mixing squeezed and unsqueezed clips, then I saw the black segments in the rendered video.

Also noticed if you use the Deshaker script on a V6 project not saved to V7 yet it's a bit squirrely. After saving the project to V7 first then the script worked fine.

I don't see this. Maybe I haven't understood the problem, so is this what you're talking about?

in my case HDV, so clips captured and encoded to NEO.avi in HDLink.
Run through VirtualDub/DeShaker to steady, put that on time line in Vegas 7e, use pan/crop to exclude wonky edges, compress clip in time to accelerate, render to mpeg, view.

EDIT: just in case also rendered to avi, again no problem.

I tried it on one clip, no problem. I usually use HuffYUV compression with HDV, but this clip is uncompressed DV.

DV NTSC output to uncompressed avi.
Deshake, output to uncompressed avi.
Load into media pool, drop on timeline.
Ctrl-shorten length to speed up.

Previews fine.
Render to AVI.
avi plays fine in windows media player.
load to vegas timeline.
plays fine on timeline

Any common compression schemes in play here? The above was uncompressed and worked fine. I'll try HuffYUV later.

All clips captured in Vegas.

A bit more investigation only leaves me more puzzled. I repeat the steps mentioned above with the same result. Also happens the same if I start with a DV clip..

If I run VDub/Deshaker outside of V7.0e and bring that clip into the timeline, then there is no problem. This is with uncompressed or huffyuv.

When i try to specify huffyuv in the deshaker.js script, I get an error message from VDub. SOmething about unable to handle input format.

Right now clueless and will just implement a workaround. Must be something peculiar with my setup.

This seems to be a clue: If I run VDub/Deshaker

If you read back over the others here, this appears to be the successful approach. Also it is as if the Audio is separated from the Video. I can hear the audio, but the Video has gone walkabout.

. . .meaning . . now repeat but FROM inside of V7e. Put a clip on the timeline and THEN use the script.

Ah, that's the difference, I'm not using John's script. I do it the old fashioned way.

What compression is occurring in his script? Field Order being flipped somehow? Something similar?
Grazie wrote on 7/11/2007, 5:06 AM
Compression? Dunno

Field Order is as was.

What is way odd, is that if you Ctrl+STRETCH it to slow it down, it works BUT the Frame Ratio is reduced?!?

Interesting huh?

Dave? Have you actually tried it using the script within Vegas7e?

. . and . . nothing wrong with the old fashioned way. Been telling that to all that know me intimately!!

"Dave? Have you actually tried it using the script within Vegas7e?"

Actually, I have been extremely busy in my "real" job and haven't had time lately. I've downloaded several versions with the intention of trying it, though. It would be nice to not have to go outside V7 to do that.

What has held me back was the the initial comment that all pieces were included in the install (VDub, Deshake, etc) and I didn't want to install over my current installs and potentially loose any custom presets. Not sure if that is really a risk though.

===>
Interestingly, I have a lot of problems with VDub/Deshake loosing the widescreen PAR. I just reset it in Vegas to what I need. I wonder if that is related?
