Title: Consistent Crash @ 4GB file size on NTFS when trying to save uncompressed file
Post by: douche on February 14, 2015, 01:57:23 PM
FAT32 has a 4GB limit, but not NTFS.  (NTFS limit is like 16TB.)  Why does AVI 2.6.8 64-bit (md5 d41a33b5a5e6a5fc0d1c27449f289a9c) crash every time I try to save a file with an uncompressed size > 4GB?

I open an mp4, then select:
Video Output (FF)HuffyUv
Audio Output: PCM
Output Format: Avi Muxer

Save file as test1.avi

Windows 7 SP1 x64

While avi is also limited to 2/4 GB. Unless you set Create OpenDML files in [output]

Thanks.  Now I am able to create a nice 10gb file.

Next step in the guide I'm working from - apply the reverse filter ... which has been removed from 2.6.  SIgh.

Guess I need to install 2.5 instead.

both can exist alongside.
2.5.6 = single frame editing
2.6.8 = newer codecs x264, x265, HD content, ... time block editing

It appears I can't use 2.5 to reverse the 10gb file, though.  it gets broken up into pieces.  I guess OpenDML is not supported.

Looks like I have no choice but to use 2.5 to decompress one of the videos I have.  This one is:

Audio: (Windows Media Audio 2) WMA2
Video: (Windows Media Video 9) WMV3

when I try to save it in uncompressed form in 2.6 using OpenDML, the status window comes up but it hangs at 0%.  Little CPU is being used.  (I only let it sit for a few minutes, so I suppose it's possible it was doing work, but 2.5 decompressed just fine.)

You load the video in to avidemux 2.6.8?
It loads and creates an index?
It does play?

You are saving to .avi container?
What video and audio codec to?

try this:
Video output: (FF)HuffYUV
Configure: HUFFYUV

Audio: PCM

Output Format: AVI Muxer
Configure: OPENDML

720p video, avc, duration 0:00:37.888 grows from 68.8 MB to 1.2 GB

Have you a 1 minute sample video WMV3/WMA2 that fails to do so?
