Images to Video

[AnthonyHunt]

Hi guys, new here so please excuse if in the wrong group. I have 4 images (Photo1.bmp, Photo2.bmp, Photo3.bmp and Photo4.bmp) which I would like to make into a video with each image showing for about 1/2 a second. I have tried with multiple images and ok but I only have 4 images which I would like to view over 2 seconds. Any help with mmpeg greatly appreciated and not much hair left here lol. Thanks in advance guys.

What software are you using to make that video?

Wishing to use ffmpeg (apologies was an error in spelling)

Every relevant mention of "mmpeg" seems to refer to FFMPEG.


Someone who actually knows what they're doing might chime in but from a few seconds of research it works something like this:

ffmpeg -r 1/2 -start_number 1 -i "photo%3d.bmp" -c:v libx264 -vf "fps=24000/1001,format=yuv420p" e:\out.mp4

(not tested)

Testing on my simulator shows you should put the '-framerate 1/x' before the '-i input' for input rate and -r xx for output rate after '-i input'



And it produced a video 2 seconds long at 30 fps

Thankyou guys, will work with those and hopefully good for me. Thanks for your time, appreciated.

[ndjamena]

ffmpeg -r 2/1 -start_number 1 -i "F:\Work\Untitled%1d.bmp" -c:v utvideo -pred 3 -vf "fps=25,format=yuv420p" "F:\Work\Untitled.avi"

This worked, but the last frame always seems to only last a single frame so I added a black image file at the end.

Thanks ndjamena, I'll try that too. thankyou for your help. After trying it was looking good but when I numbered the images in the actual images, 1,2,3,4 to check each frame was being displayed, number 4 was not being displayed.

[ndjamena]

Are you sure it's not there? Like I said, for some reason FFMPEG will make the final image last only a single frame. I had to add a fifth image to get the video to last 2 seconds (plus the extra frame).

ffmpeg -r 2 -start_number 1 -i "F:\Work\Untitled%2d.bmp" -c:v utvideo -pred 3 -vf "fps=25,format=yuv420p" -t 00:00:02.000 "F:\Work\Untitled.avi"

adding -t 00:00:02.000 trims the extra frame, leaving 2 seconds worth of video made from the first 4 images.
