how to merge 2 videos into 1 video without losing FPS?

Hi,

I have 2 x 10 mins videos, both with the 59.94 FPS. Since the videos holding the same experimental phenomena in 2 videos. I want to merge them two videos without losing any frame, (I achieve this by using the window 10 but losing my frame rate means losing data). I also have tried the code below but what this code is doing putting both videos side by side this is not what I am after. I am looking to merge 2 videos into 1. If anyone can help that be great!

Code:

close all; clear all; clc;

vid1 = VideoReader('test.avi');

vid2 = VideoReader('test1.avi');

videoPlayer = vision.VideoPlayer;

% new video

outputVideo = VideoWriter('finaltest.avi');

outputVideo.FrameRate = vid1.FrameRate;

open(outputVideo);

img1 = readFrame(vid1);

[rows1, columns1, numColors1] = size(img1);

img2 = readFrame(vid2);

[rows2, columns2, numColors2] = size(img1);

img2 = imresize(img2, [rows1, rows2]);

imgt = horzcat(img1, img2);

while hasFrame(vid1) && hasFrame(vid2)

img1 = readFrame(vid1);

[rows1, columns1, numColors1] = size(img1);

img2 = readFrame(vid2);

[rows2, columns2, numColors2] = size(img1);

img2 = imresize(img2, [rows1, rows2]);

imgt = horzcat(img1, img2);

% play video

step(videoPlayer, imgt);

% record new video

writeVideo(outputVideo, imgt);

end

release(videoPlayer);

close(outputVideo);

sir, may be use the follows code to ref

you can read the book 《计算机视觉与深度学习实战》

clc
close all
clear all
vid1 = VideoReader('xylophone.mp4');
vid2 = VideoReader('traffic.avi');
% new video
outputVideo = VideoWriter('finaltest.avi');
outputVideo.FrameRate = vid1.FrameRate;
open(outputVideo);
sz1 = [vid1.Height vid1.Width];
sz2 = [vid2.Height vid2.Width];
while hasFrame(vid1)
    img = readFrame(vid1);
    writeVideo(outputVideo, img);
end
while hasFrame(vid2)
    img = readFrame(vid2);
    if ~isequal(sz1,sz2)
        img=imresize(img,sz1,'bilinear');
    end
    writeVideo(outputVideo, img);
end
close(outputVideo);
% display new video
vidObj = VideoReader('finaltest.avi');
while(hasFrame(vidObj))
    frame = readFrame(vidObj);
    imshow(frame);
    title(sprintf('Current Time = %.3f sec', vidObj.CurrentTime));
    pause(2/vidObj.FrameRate);
end
