Hello
I exported videos on shotcut (23.09.29) with the Nvidia GT740 video card in H.264 and works well! Would you like to know why the developers disable the NVENC for the 470 driver?
I tested on Linux Ubuntu 24.04 and Windows 10
Shotcut is built with recent SDKs. Newer SDKs drop support for older hardware. Loss of support for the GT740 is a decision made by Nvidia, not the Shotcut developers.
I do not increase the SDK version arbitrarily simply to keep up-to-date as much as possible because I know that requires newer drivers and hardware. However, the SDK version had to be increased to support AV1, which I feel is an important video codec to support. Shotcut is not going to go backwards, but you have options.
Yes, Nvidia stopped update the driver because the hardware is 10 years old. Nvidia sells GPUs.

The 700 series driver will be available for WIN 11 until 2031 (end of 10-year WIN 11 support)

Ubuntu 24.04 recommends the proprietary Nvidia 470 driver. Ubuntu 24.04 LTS is supported until 2029. Upcoming Ubuntu LTS releases (2016) will likely stop recommending the proprietary Nvidia Driver 470 and will install the open source Nouveau driver.
It may be possible to use the Nvidia 700 series NVENC with Nouveau driver through VAAPI (I have not tested this option).
Driver and SDK are two separate things. The old driver may be available, but a recent SDK will refuse to use it.
Shotcut, Kdenlive and OBS Studio no longer support Nvidia Driver 470, but VLC Player and SimpleScreenRecorder still support NVENC (1st) software I tested
AV1 started in 2018, but only available in Nvidia RTX 40 series. AMD RX 7900 series and Intel ARC A380 which surprised the market with the performance of its hardware decoder.
