mp4 render crash

[ajfudge]

Hi. Can someone tell me what's wrong with this:



It's an element contained in a .vsp
Right now I'm trying to "connect" & render 1 video file + 4 .vsp (inttertitle card.mp4, segment1.vsp, ... segment4.vsp). Each contains segments that run continuously and I need to combine into just one video file (mp4 HD format). But every time the render reaches that file (above) (17% of the total render), it crashes. There's nothing else on that timeline except that mp4 file and a wav file.
I don't understand why it's happening. I have done it successfully before in Youtube HD format.

SmartProxy is enabled, but I don't see how that's relevant to rendering.
I have tried re-converting the video file into versions: one has .mpeg4 codec, the other has .H264.
I also downloaded & installed VSPX4 SP1, updated my codecs, drivers, downgraded Quicktime. But the result is still the same as far as rendering the whole project goes: crashing at 17%.

There were enough RAM & CPU when I did the rendering so I don't think this is a hardware issue.
I also tried disabling SmartRender just to see if it will react positively.

There came a time also when the render passed 17%, but it crashed when it reached 94%.
Interestingly, when I rendered segment1.vsp only (to mp4 HD), it also passed 17%, but then it failed to finish also.
Right now, I'm going to re-convert the file to a different format to see if the whole crash is related to mp4 (which is kind of confusing because I have rendered many mp4s just last week and they were successful).

So I'm curious, is there a limit to how many "connected" .vsp files one can render successfully?
And is there a certain mp4 type that VSP can't handle properly?
Thank you in advance.

UPDATE: I reconverted to .mpg, and it worked finally. Butt I still want to know what's wrong with .mp4

Just because you have rendered MP4 files successfully in the past doesn't mean that this one in particular couldn't be corrupt in some way. If you contine to have the same problem then there could be some other underlying issue. But if it's just this one clip I would just shrug it off as one of those things.

I'll consider the possibility of file corruption (which is questionable coz I converted the source file to 2 diff versions of mp4 and 1 mpg, and the mpg worked. I have corrupted avi's & converted them to mp4 but they rendered fine). I'll also keep a sharp eye on other mp4s in future renders.
But to shrug it off is not a very easy thing to do coz it's just so frustrating.
Anyway, lesson learned: learn to depend on the alternative. :sigh:

The issue will still depend on a number of things. can you tell me what happens when the program crashes? Are you getting any error message? Also if you are using VS X4, it is recommended that you use the latest version QuickTime.

hi.
There was a popup message. I can't remember the exact message, something like "The program crashed. A crash dump has been created...."

I said in my first post that during my attempt to render (4 vsp's inside one vsp) in mp4 web, the crash happened at the end.
But when I render each vsp separately, it completed successfully.
I also tested thet DVD formats, and it worked.
Suffice to say, the crash happens at that very point/timeline when rendering the project to mp4 HD only.

I converted that clip to different formats already, so I guess I'm convinced now that the source file was corrupt. Oh well.
