Comment (by Jason Dove):
Ah, I see. I didn't realize how h264 was stored, frame cropping, etc.
This produces output (100% for me) that doesn't have cropping set
properly:
{{{
ffmpeg -hwaccel cuda -hwaccel_output_format cuda -i https://test-
videos.co.uk/vids/bigbuckbunny/mp4/h264/1080/Big_Buck_Bunny_1080_10s_5MB.mp4
-i https://peach.blender.org/wp-content/themes/bf-
bunny/graphics/header1.jpg -filter_complex
'[0:0]scale_cuda=format=yuv420p[v];[1:0]hwupload_cuda[wm];[v][wm]overlay_cuda[ov]'
-map '[ov]' -t 00:00:05 -c:v h264_nvenc -y green-line.mkv
}}}
while this version that seeks slightly does have cropping set properly
(again, 100% for me):
{{{
ffmpeg -hwaccel cuda -hwaccel_output_format cuda -ss 00:00:0.01 -i https
://test-

-i https://peach.blender.org/wp-content/themes/bf-
bunny/graphics/header1.jpg -filter_complex
'[0:0]scale_cuda=format=yuv420p[v];[1:0]hwupload_cuda[wm];[v][wm]overlay_cuda[ov]'
-map '[ov]' -t 00:00:05 -c:v h264_nvenc -y no-green-line.mkv
}}}
