Any Work-Arounds for Corrupt 2GB+ AVI's?

[spearsd]

Does anyone have a work-around for AVI's greater than 2GB being corrupt when recording from a track file? I would like to record lossless framed video from a track file.

Thanks,

The one or two times that I went over 2 gigs, and could open the tracks there were four different views on the same screen. I don't think there is a workaround.

Record your mission in pieces and splice it together w/a video editing tool.

Hi all,
I may have found a solution. I've opened the large AVI in VirtualDub which rebuilds the corrupt indices, and then save it off in "stream copy" mode as either a single large AVI or a segmented AVI. Tried it on a 3.5GB AVI and it seems to work like a charm! http://ubbxforums.ubi.com/infopop/emoticons/icon_biggrin.gif VirtualDub is REALLY a nifty piece of software along with AviSynth.

Well, the video loads fine with VirtualDub 1.5.10.1, BUT the PCM audio stream isn't loaded from LOMAC AVI files >2GB.

I also tried using AVISynth 2.5 to extract stream information for the LOMAC AVI and it claims the AVI contains NO audio stream.

So, any ideas why I can recover the video stream but NOT the audio stream?

The audio stream may or may not be recorded even though it says it does. What I have noticed is that the audio is recorded separately, then it's combined at the end of the render sequence.

Well, every tool I've used confirms the audio stream is not combined with the AVI (maybe, due to the audio processing pass not being able to read the 2GB+ AVI file generated from the rendering pass?).

I wonder if there's a way to get LOMAC to record the audio in a separate WAV file?

I suppose I could record in the background while the sound is rendered and then crop it with audio tools and then re-combine it? Damn, what a pain in the **** http://ubbxforums.ubi.com/images/smiley/35.gif

A very good alternative to this .AVI thing, is to use fraps. With the AVI thing, you render frame by frame, and this takes a long time and also takes up a lot of HD space, and then you have to worry about the 2 Gig limit.

I suggest you use fraps, slow time down 3-4 times, and speed the clips up 3-4 times. That way, you won't miss a single frame almost, because things move so slow in the game. And then you can just stop recording, move to a better scene, then start recording again, which gives you more control. That's just my opinion, though.

I have a fairly quick computer, and I slowed the game down as you said. The AVI tool renders faster (for me) than by doing it your way. I recommend trying it both ways to see whats best for you.

Excuse a silly question, but how do I "slow time down 3-4 times" and then "speed up the clips 3-4 times"?

As for 2gb limit and audio thing.

VirtualDub fixed the video file here sucessfully, and all the views was just as I wanted them, so no need to worry about that. The only drawback is the video files have no audio.

As a workaround, perhaps starting another render in very low resolution and some low quality good compression codec only to get avi with sound (we have the video from the first render). Then just extract audio from second track and combine this with the first one.

I know this is not perfect but better to have this than nothing.

Or perhaps start playing the game track -no render just replay - capture audio with some
third party software, and then combine this with video.

You slow down time in game for example for 1/2 value and capture video in fraps by setting half of fps for normal movie. Then you load the clip into another piece of software and change the fps to the original value.

This is often used by people capturing material for movies in il-2 ww2 flight sim. There aint any avi render tool there. They set the track playing speed for 1/2 or 1/4 of normal time, recorder the avi with 15fps, and used virtualdub to restore original framerate.
(between 24-30 fps).
