This example assumes the video is 3600 frames long: To create a looping video, split the video into two halves and then use a filter to blend them together. ffmpeg -hwaccel cuvid -f image2 -start_number 0300 -i _%04d.png -framerate 30 -pix_fmt p010le -c:v hevc_nvenc -preset slow -rc vbr_hq -b:v 6M -maxrate:v 10M -c:a aac -b:a 240k.To start from a different frame, use the start_number parameter: ffmpeg -hwaccel cuvid -f image2 -i _%04d.png -framerate 30 -pix_fmt p010le -c:v hevc_nvenc -preset slow -rc vbr_hq -b:v 6M -maxrate:v 10M -c:a aac -b:a 240k.mp4 -vf scale=1280:720 _1280_720.mp4įor h265 encoding using nVidia hardware acceleration, try something like: Once you’ve output a video, it can be scaled using the following examples: Change to your desired output filenameĪdding the option -vf scale=1920:1080 will scale the video on the fly.Change to whetever you images are named as before the regex.If your image sequence filenames have a different number of leading zeros, change the regex pattern from %04d to something else, such as %02d for 2.I have an nVidia card so I used their codec (h264_nvenc) but you may want to use libx264 instead.Assuming Windows is used here, but this should also work for Linux and Mac.ffmpeg -f image2 -framerate 30 -i _%04d.png -c:v h264_nvenc -preset slow -qp 18 -pix_fmt yuv420p.

Copy the binary FFMPEG.exe to the folder with the sequence, then in a command prompt enter the following:.In this circumstance I have about 5000 frames stored as png image files which are named sequentially xxxxx_0000.png, xxxxx_0001.png, xxxxx_0002.png etc. The only good way to do this seems to be via the command line.
