Nvenc h.265 and output video resize
Posted: Fri Nov 18, 2016 10:33 pm
Hi,
I use Mediacoder (registered) to encode with Nvenc (before with h.264 and now with h.265) and it's work very well.
However, when I use Nvenc with h.265 output pixel size is 1280x736 for 720p and 1920x1088 for 1080p (viewport size is ok). It seems that Nvenc h.265 force modulo 16 and resize... Nvenc doesn't do that with h.264.
Is this a normal, Is there an explanation? Is there a command line parameters to force modulo 8?
I found that Nvenc+h265 is very fast and the gain in hard disk space for low-medium quality 1080p videos is great! I encode 1-2 hours, two times a week of sport training (phone, go-pro, etc...), in highest resolution possible (to compare technical evolution) and need to store the video 2-3 years... x265 is perfect for that!
Thanks
