Export file incomplete or crash or 'failed' message when exporting higher than 720p/30fps


Recommended Posts

Hello everybody. I am new to VideoPad and this forum. After some playing around with the free edition I was so happy I decided to buy the professional edition (without premium support though).

 

However, after making my first video project I found the program is unable to export the video at a higher setting than 720p/30fps. When I try 1080p/1440p one of three things happens:

  1. After about 1% processing it jumps to 100% and the export queue shows a green 'complete' message.
    The exported video is about 1 second long. Obviously it's not complete.
     
  2. After about 1% processing the export queue shows a red 'failed' message.
    The export video is broken (cannot render) and very small in file-size.
     
  3. The same thing happens as mentioned in 1 except that I get a messagebox saying VideoPad has crashed.
    I get the option to report a bug (which I did) or click no. In either case the application abruptly exists after.

I have imported 6 source files (mp4) which are 1.2GB in size altogether. These are CS:GO recordings made with NVIDIA ShadowPlay with the following settings: Recording in-game resolution (1440p) / 60fps / 60mbps / H.264.

One of the files is the main video file from which I use 45 seconds and the audio. It is cut up in several scenes. Some scenes are running at 400/800% speed. The other 5 video files I use as overlay tracks (scale + position effects to put them in the bottom left/right corner) with simple fadein/fadeout. I have removed the audio tracks for these clips in the timeline.

 

Event Viewer shows this Warning several times: The NVIDIA OpenGL driver has encountered an out of memory error. This application might behave inconsistently and fail. However, it does not always occur exactly around the time the export fails.

 

I have used TechPowerUp GPU-Z to monitor the GPU's memory usage which goes up to about 1GB (out of 4GB) right before VideoPad stops/crashes. So I doubt it has to do with the out of memory error from NVIDIA.

 

Furthermore I have tried:

  • closing applications to preserve system memory.
    During the export video process about 8.2GB out of 16GB system memory is used (and then the process stops/crashes).
    VideoPad's memory usage goes from 280MB to 3.2GB and back to 280mb when processing stops.
    So, memory availability doesn't seem to be the problem.
  • different file formats (avi, mkv, mp4) and different resolution/fps settings (combinations of 1080p/1440p and 30/60fps)
  • disabled ShadowPlay before even starting up VideoPad. Also didn't make a difference.
  • using different disks for input, output and the Temp directory.

I think my system is well up to the task:

  • The samsung ssd 830 has the fixed firmware and this is my C drive
  • The 4 hitachi drives are in raid 10 setup and this is my D drive
  • The revodrive is actually 120GB (it is raid 0 internally) and this is my E drive

My Windows installation is about 2 years old (don't remember exactly) but I think I upgraded from Windows 8 to 8.1 and then to 10.

I would like to do a clean install some time but I also use this system for work and I have not yet found a good moment to do this.

I am using the latest NVIDIA drivers/software.

 

I have searched the forums and the most similar issue I found was this one:

http://nch.invisionz..._+export +crash

Although this should've been resolved in the latest version (I am using 4.22 Professional) the topic seems to have similarities to my issue.

 

If you need any further information or log files etc please let me know. Thank you for your time.

The system/video memory needed by VideoPad are depend on the complexity of the problem.

 

Could you let us know how your project was arranged? Maybe we can find a way to do it in such a way that it require less memory to export.

 

The first thing I'd like to find out is that if it ran out of system memory or video memory.

Thank you for your reply. I think you're on the right track (no pun intended). I was already testing this by creating a new project with just one video-clip with a simple fade-in effect. I was then able to export the video to 1440p and the application's memory usage only reached about 500MB.

 

I am really curious as to how the original project could be arranged differently as it doesn't seem that complex to me.

One thing I could think of is convert the video's beforehand to a lower resolution as I am now using the scale effect anyway.

Ok, I also could have used one less video-track :) Does that matter a lot? How would one ever do a video with like 10 overlay videos?

I have made some unnecessary cuts but that doesn't really cost a lot of memory right?

 

PS: after watching the final video it is clear that the overlays are almost useless in this case as the action is to fast to watch the main video and an overlay simultaneously. The viewer would have to pause or rewind the video in order to see them both (or even three total). However, I'dd think it should still be possible to have multiple overlays without the application crashing on video export right?

Yes, each overlaying track will increase memory consumption a few times multiply the resolution.

 

The only way to get it work now is to combine the tracks in separated projects and then merge them in the final project. But I wouldn't recommend since it will be a lot of work. It'll also take a lot longer and you'll have to use a lossless codec.

 

We'll work on to find a way to reduce memory consumption but nothing I can tell at this point. I'll post the update here if we have any progress.

 

Also, VideoPad was built 32bit so maximum memory it can use is 4G. I'll bring this issue to team see if we should release 64bit builds.

 

Thank you for your post.
