I have a strange problem that has arisen during the past year's updates (not exactly sure when it started). If I create a Muvizu file, in any codec, that is over 2gb in size then that file is unreadable to most media players and all editors. 32bit, 64bit, old version, new version, it makes no difference. If it's under 2gb all is fine.

I did all the usual stuff you'd expect - updating drivers and codecs and the like, and resorted to reinstalling windows (7 64 Ult) but nothing makes any difference. Has anyone else experienced this problem? If so, please let me know - I can't work out what the source of the problem is, so any info would help.

I had that same issue and tried all of the things you mentioned too. I have so many different graphics and animation programs loaded onto my computer that I thought it had something to do with that. My "workaround" with Muvizu has been to do my rendering in smaller "chunks" (under 2 gigs) and then edit them together for the final output. So far so good.

I'm not sure what's causing the problem either but I'm glad you mentioned it because I thought I was the only one having this issue.

Tip as Mysto says smaller chuncks are the way to go as I'm sure you already realised. They give you more flexibility too editing wise I feel

Thanks guys. Mysto, what is your system? The good folks at Muvizu HQ couldn't replicate my problem, even using one of my sets, so it must be something we've got that's different.

My system is;
Win 7 Ult 64bit SP1
i5 2500k
8gb RAM
ASUS mobo
Nvidia GTS 450
SATA drives, various USB attachments, running the 64bit version of Muvizu. Nothing weird in the background (by wierd I mean downloaders or system managers or any junk like that)

My system is:

Win 7 pro 64bit SP1
i7 870 (upgraded from i5)
12 gig ram
intel DP55WG mainboard
ATI FirePro 4800
2 SATA drives (500gb-1000gb)
1 External 500gb usb drive

I have various usb devices that I use every now and then but they aren't plugged in all the time. I have a virus and malware program running in the background but nothing else and I'm running the 64bit version of Muvizu as well. I'm wondering if it may be an issue with one of the device drivers installed on my system.

Here lately I've been creating my videos in pieces and editing them together so I haven't encountered the problem recently. Very strange...

I'm noticing the same thing myself. I don't know what editors you guys are using, but with Windows Movie Maker, I can't import a Muvizu file bigger than 2 GB.

The problem is with the type of AVI file we generate. We generate what would be called a version 1.00 AVI, there's a standard API in Windows (called Video for Windows) which can be used to generate these clips. We used this because, well, it was quick and easy to implement. These clips have an internal limit of 2GB in size - I could bore you with the technical details as to why, but I won't bother.

We are planning to change the way the files are written to use another API which will support avis greater than 2Gb in size. But as ever, it's on the long and growing list - and there are higher priorities at the moment - so I cannot say when this will happen.

Usually if you are using a codec of some variety, then you generally should end up with files quite a bit under the 2GB limit, though I guess that's not always going to be the case.

Yep, thanks for that mcmillan - unfortunately the codecs available in the 64bit version are extremely limited compared to the 32bit version, so it's either huge files or smaller, crappier looking files. Huge files it is then


Also, Mysto, are you planning a moon launch or something? What kind of a system spec is that?!! Must be nice to use though...mmm, power...

I render everything as I want - when I load into Sony Vegas if the "computer says no" then I run it through VirtualDub and then Vegas will load it.
