Please show us the command line you tested together with the

Thanks for reply.
About 4.6 hours!
The software that I am using to enhance videos will output to jpeg, I'm
outputting to uncompressed 16bit TIFFs at the moment.

20k frames are a mere 800s of a 25fps movie... how slow is cpu process ?
afaik nvenc can only do mjpeg_cuvid for stitching images, it won't work
with tiffs...
e.g. ffmpeg -vsync 0 -hwaccel cuvid -c:v mjpeg_cuvid -framerate NN -i
image_%04d.jpg -c:v h264_nvenc x.mp4...
Hi
I'm using ffmpeg to combine a large number of TIFF files into a single
video.
The TIFFs are the result of upscaling videos. They are large in number,
typically 2 or 3.
The process is slow.
Is there a simple way of using the GPU ram? I have a NVIDIA 2080 TI with
11GBof

Hi there,
I am staring at the following guide to re-encode an existing avi
(mpeg4+mp3) into MP4 (h264+aac):

My video is such that:
$ ffprobe -show_streams -show_format -print_format json -i input.avi
[...]
Input #0, avi, from 'input.avi':

to force the subtitles stream to be displayed by default, so I use the
"-disposition:s:0 forced" option.
However ffmpeg fails to properly
