Large Buffer Malloc error


Active member

While trying to recode a AVC 422 video to AVC 420, I end up with a "Large Buffer Malloc: no more memory"

I have 4 other files of the same type, which do not have the error and recode just fine. I even ran the original file thru QSF, no diff.

Can you send an email to support about this. It'll be easier to get the samples we're going to need that way

What 818g? The only one listed for downloading is 818a. There's a 64bit version of VRDPro?

I have to go back and go thru the file that caused the issue. I discovered well after posting that the file has got a few sections of the file that are heavily glitched. It seems the VRDPro wasn't getting thru those very well.

I just ran into this issue again. The file was a capture of 1.5 hours of The CW network feed: H264/422. I was running the search for ads, stopping and restarting every now and then as I was looking for particular images. Used Ctrl-C to capture a few. But, at about halfway thru the scan, up popped the out of memory error. The file was 100% clean, no glitches. I've already deleted the file. A ample would had to have been at 6GB in size.

I'll have to try this again when a new release is posted.


You don't have a short sample that you could send to me to download and test on my Pro 64bit Build.

I still can't convert 4k/50p HEVC MPEG-TS 422 files to 4k/50p AVC with the new 64bit Build, but i can do the cutting side of it, but i think that may have something to do with the 4.2.2 part, i can however now edit and reconvert my 4k/60p HEVC 4.2.0 GoPro files to 4k/60p AVC.

A short sample won't work. It took over an hour of video before the error occurred. I currently do not deal with 4K video, so I have not run into your issues.
