Something wrong with ExBlockSize parameter value.
Please show your additional info: SVP tray menu - Information - Additional information.

P.S. I translated error text from Chinese with google translation. I got:

Runtime error: File not found

Then it is wrong SVPMgr.wsf. There are no file operations at SVPMgr.wsf(94, 3).
I think it is from another version of SVP. Please reinstall SVP 3.1.2 from download page (Lite or Full, it does not matter), replace files from SVPMgr_CommonAppData.zip. And try again.

It is great that You ask the same. I think You can help me.
I couldn't fix error with local appdata folder if User name in Chinese.
I did another thing. SVP-Manager working with Common appdata folder.
It is works for me under user 林柏丞. What will You say?

Try this: SVPMgr_CommonAppData.zip

1. Exit from SVP-Manager.
2. Unpack to SVP folder with file replacing.
3. Launch SVP-Manager.

how did you generate that report? Just Excellence?
Just MS Excel and couple of hours wink

if I use "mode=0", it halves the resolution of the video to 960x540
It shows to me the same.

I can't find any success way to open MOV via DirectShowSource too.

Only with "mode=3" I get full resolution.
Then I recommend to convert to any other container and open not through QTInput. QTInput(mode=3) adds fake dropped frames.

For example.
You can use yamb to produce MP4 (without re-encoding). Or you can use gdsmux to produce MKV (without re-encoding too).

Thank you for logs and SVPmark results.
I see, your SVP settings are normal. SVP must work good at these settings.
Something wrong with you system configuration or hardware. And I think it is memory size.

I was wrong sorry. here is the test redone
1. I don't understand you. Where you was wrong?

I need more info.
2. What memory size installed in your system?
If you using windows 7 32 bit I think it is less than 4 GB.
3. Are you using pagefile and what its size?

And you still did not answer:
4. Look at performance graphs window. How many memory used by player while it crashes (in MB)?
Take screenshot please like this.

About CFR calculation. This is graphical result (I computed it in MS Excel): deviations of frames timeCodes. Data of clip2 used.

http://www.svp-team.com/forum/misc.php?item=1977

Graphic shows how early (lead) or later (lag) each frame will be dispayed if play frames at constant frame rate 29.95 fps.
As you can see maximum deviation is about 2 ms. MKV and MP4 data is close to each other. And we have one drop at the middle of the video. We must to insert one duplicate of frame to fix frames lead after drop.
QTInput(vfrFPS=29.95) and DirectShowSource(fps=29.95, convertfps=true) will do it automatically. All frames will opened. Without losses. All frames are at its own places.

Normally video memory must allocated when playing and released when close video.

I checked how works QTInput. It works good with different value of mode parameter.
QTInput with mode=0 works good. Frame # 2108 is copy of 2107 in second clip and FramesCount is 5111.

QTInput("wide ipd test cam2 t02.mov", vfrFPS=29.95)

This script gives perfect sync with true length.

But with used by You mode=3 I can't see duplicate frame in the region of #2107 frame. This mode is not frame accurate. It potentially can lead to lose synchro.

unable to init FlowLib [code 0x3FFFB]

It looks like you have old version of SVP with video memory leaks troubles (about 0x3FFFB error).
You need to install latest version of SVP 3.1.2. Download page.

I changed the supported thread from "Auto" to 4, and video lagged, so i changed to 2 and still lagged, then changed again to "Auto". Guess what? It doesn't lagged and crashed anymore
Of course. Any change lead to script reinitialization. You can do 10-20 reinitializations before crash. Free video memory not released. It is error 0x3FFFB.

Um, "pointing the framerate", I presume, doesn't do the same as AssumeFPS?
No. It is different things. If you open video with wrong FPS you will lose original frames or will get unwanted duplicates. For example opening 30 fps video with framerate 1 frame/sec will lead to losing 29 frames each second. And AssumeFPS in this case can't help absolutely.

when AviSynth does the "convertfps", will it correct the drops by duplicating frames so that the hard drop doesn't throw the clips off sync?
Yes. In your case it will be added no one duplicate frames to the first clip and only one to the second clip.

Try to open MOVs by DirectShowSource. If it works then it is nice (on my system it can't open MOVs, I don't know why.., I'm searching hmm ).
Otherwise point in QTSource right framerate (29.95). And with only one hard-drop you can forget about sync issue wink

Ough! Yes! I was wrong about floating VFR.
It is constant framerate with a little deviation and one hard drop in second clip.

        sampleCount[919] = 2 (0x00000002)
        sampleDelta[919] = 100 (0x00000064)
        sampleCount[920] = 1 (0x00000001)
        sampleDelta[920] = 200 (0x000000c8)
        sampleCount[921] = 1 (0x00000001)
        sampleDelta[921] = 100 (0x00000064)

Base framerate is 29.95 fps (or 29.95048 to be precise).
You can open it and work with it as CFR:

DirectShowSource("[filename]", fps=29.95, convertfps=true)

After that you can get synchro by 0.003 sec (3 msec) wink

Later I will tell about how I checked it.

Good. Both video has identical length. Difference in 0.03 sec is very minimal to notice. But frameCount is different: 5111 and 5109 (from first log).

what happens when you VFR->CFR?
it will duplicate previous frames to fill the gaps, so that the length of the video stays the same?
Exactly wink

It is not all. I'd like to understand what is inside MOVs. Constant framerate by intervals with multiplied index from base framerate or real fluent variable framerate.

As you can see base framerate is not constant (intervals with bolded values). It is from 29.9471 to 29.9518 fps.
I think it is not precisely (maybe) because standard is 29.97 fps. I will make another analyze to confirm it.

"3. replace drops" part is done by SVP, then?
Yes.

After VFR->CFR opening, how does SVP know which frames have been dropped and need to be interpolated?
By straight comparing each current frame to next frame.

those movies are in QuickTime so I'm using QTSource. I suppose that one does not support convertfps=true?
Yes. You are right. It just combines all frames together without real interframe delays. I'm not sure it is IMHO.

The DeFish plugin can be added to the AviSynth script to follow after the SVF framerate conversion, I suppose?
Do you mean VFR?
VFR=variable frame rate smile

Yes. You can combine filters in avisynth as you wish. In this case for example:
1. open with VFR->CFR conversion
2. apply DeFish
3. replace drops

Can you share it to me? Public or private. As you wish. If it is not top secret video of-course. wink

left camera video.mov - 29,951 fps; length 2:50,680
right camera video.mov - 30,928 fps; length 2:50,655
It is average framerate. You need to know base framerate to convert VFR to CFR without losing of quality and to save original speed.

They are the same length, and play in sync if inserted into a Vegas project
This is good.

They will not pair into a stereoscopic subclip because of too much framerate difference in the media files
I need to look to video.

If I re-encode the files with VirtualDub to just simply force them into the same framerate (29,970), they will drift off sync because of the rate difference
Something wrong with open or with conversion.

Does AviSynth have frame resampling options built in?
Yes. It does, see DirectShowSource(convertfps=true). It converts VFR to CFR.

I also need to apply a fisheye removal to the video
You can process video in avisynth without removing fisheye. I think it will be better to work with source than with Vegas (wrong/buggy) output. It gives better chance to repair drops.
