Ffmpeg concat video then the video is weird how to#

I am not sure how to read ogg files into Avisynth, but there is probably a way. If the clips are constant frame rate that is not a problem.Ĭombining clips by making a new clip containing both like this (whether through avisynth or not) requires recompressing the video, and reduces video quality/increases file size. The problem is that the N-th frame from one file may not be at exactly the same time as the N-th frame from the other file, if they are variable frame rate, this is something that AviSynth handles perfectly for you. This actually lets you do a lot more image processing than just side-by-side, you can do arbitrary scale/overlay/background/etc.

plus any other options you want.ĮDIT: Another way to do it (not fast) is to dump the frames from both files to png and combine them with ImageMagick (for example montage) or similar image processing tools. Make the following input.avs file: a = AviSource("first.avi") It is probably easiest to do this using Avisynth. So - what's wrong with my parameters and what am I doing to cause these FFMPEG errors?ĭuration: 00:05:20.98, start: 0.001000, bitrate: 2273 kb/s If there is a better route to this, please let me know. ogg as FFMPEG didn't want to combine two. Once I get the cmd working I'll move it to a better location in the output. ffmpeg-i video1.ts -i video2.ts -i video3.ts -i video4.ts -c copy -map 0 -map 1 -map 2 -map 3 video.ts.Unfortunately instead of creating an MPEG-TS file with 4 programs, each with an audio and a video stream, it has created an MPEG-TS with 1 program, each with 4. the placement of the 2nd video at 100:0 is arbitrary. I have converted 4 video files to MPEG-TS format.I padded the 'output' to be rather large in an attempt to understand the params.During the combination process FFMPEG prints lots of errors that read like: Suffice to say that the resultant video is non-playable. To this end I've tried the following cmd:įfmpeg -i subject.ogg -vf "pad=3*iw:3*ih movie=clinician.ogg overlay=100:0" combined.ogg My goal is to combine them into a side-by-side presentation using FFMPEG. OGG files of similar size, FPS and duration.
