Shotcut fails to export video file

[Woody_Brison]

I go to export and the export fails. It writes a very small file, 48 bytes, as follows:
NULNULNULftypisomNULNULSTXNULisomiso2avc1mp41NULNULNULBSfreeNULNULNULNULmdat

For settings I’ve got video mode = 1920x1080, 16:9, 25 fps, Progressing scan mode, colorspace = ITU-R BT.709. I tried 24.02 fps, same result.

I’m using Windows 10, v.22H2 on an ASUS ROG Strix Scar Edition GL703GE-IS74 Gaming Laptop. CPU = Intel i7-8750H @2.2GHz. NVIDIA GeForce GTX 1050Ti 4GB (whatever that is, I don’t play games these days.) 16GB DDR4 RAM; C:=256GB ram + D:=1TB hard drive. Other programs have no problems with either drive and Shotcut ~does~ write this small file, exactly the same on the D: drive as on the C: Ergo the disk is not write protected.

Per Windows Task Manager, 5Gbyte memory used, 10Gbyte avail. Graph only shows a very slight bump as Shotcut tries to export. Not out of memory.

The time on the Jobs window (failed) is 00:00:00:15. At that point there is one clip, video. Has one filter, Gain/Volume. Removed that filter, no change in result.

I went thru my video and removed every filter on every audio clip. No change.
I removed every filter on every video clip. No change.
I removed every filter on every image clip. No change.
I removed the audio track. No change.
I removed the video track. No change.
I started a new project, put one image in (making a new track). No change, except the log is short! Here it is:

Can anyone shed light on “Nvidia driver for nvenc”? I’d be OK for now if I could run off just the pentium.

This forum has a file on export failed with my same exit code -1073741819,

Export failed - Find solutions

Your export failed for one or more reasons. There is always a reason why it failed. Below are the posts by others describing their faults and solutions. This tutorial is not a definite tutorial as you may have a unique situation not described in here. Time Code After failure to export it may display a time code, make a note of the time displayed and look on your timeline to see what’s there that could be causing the problem. It could be a clip, audio or video file, transition. [firefox_20…

last issue, 2020 June. This problem is not mentioned that I can see. But, it’s obvious people don’t appreciate this resource…

Any help, I will be certain to post whatever resolution I wind up with, and also a link to the finished video.

@Woody_Brison

The minimum required Nvidia driver for nvenc is 456.71 or newer

There your problem. Turn off the hardware encoder option (within Shotcut’s Export) or upgrade the Nvidia driver. There is no special driver for nvenc; it is simply the graphics driver.

Wow, it was that simple? I hunted for that checkbox but for some reason could not find it. Thank you! I’m now doing some final tweeks on the video, will post a link here.
