Error using VideoWriter/writeVideo (line 344) Frame must be 2560 by 1360 - Help

Hey,

This is my code for writing a video that syncronizes my data plot with the behavior video. I keep getting this error and I dont know how to fix it.

VID = VideoReader('Trial-12.m4v');

%Creat matlab structure to make a new video

v = VideoWriter('ko_base_livetrace.m4v','MPEG-4');

%Frame rate of the video you are reading

fps_vid = VID.frameRate;

%Frame rate of FP data

fps_data = signal.sampling_rate;

%How long you want new video to be

vid_duration = VID.duration;

%Frame rate of created video will be the frame rate of the behavior video

%v.FrameRate = fps_vid/300;

v.FrameRate = (floor((VID.NumberOfFrames/5))+1)/vid_duration;

%Number of frames in this new video

vid_frames = floor(vid_duration * fps_vid);

%Open the new video for writing

open(v);

%Create a structure to hold the FP trace data as needed as you generate frames

dataNeeded = [];

%Create a list of the times to pull from for x-axis of plot.

times= [1/fps_data:1/fps_data:(fps_data*vid_duration)]';

%The time in the behavior video you want to be the start of the new video.

startTime = 0;

%Find which frame this is in the video

frameStart = startTime*fps_vid+1;

%The location in FP data trace will always start from when plotting during

%video (just the start time in the FP data)

minPoint = (startTime)*fps_data + 1;

minD = -2 %floor(min(deltaFTrialTwo(minPoint:vid_duration*fps_data))*100);

maxD = 4 %ceil(max(deltaFTrialTwo(minPoint:vid_duration*fps_data))*100);

%Loop through frame by frame of behavior video, create matlab figure

%displaying that frame of video plus a plot of FP data up to that time

%point. Then save as a frame of new video.

frameCount = 0;

for n = frameStart:5:(frameStart+vid_frames)

%Create new figure

p = figure(1);

set(gcf,'color','w');

%Set the dimensions of the figure to be the size of your monitor

set(p, 'Position', [1 1 1920 980])

%Create new subplot location and fill with current berhavior video

%frame.

subplot('Position',[0.05 0.5 .9 0.6])

imshow(read(VID,n));

%Create new subplot for FP trace

s = subplot(2,1,2);

%Data needed for this frame for FP plot, is all data from minPoint to

%current time.

%THIS IS ALTERED TO SUBTRACT 1 SECOND FROM FP DATA TO ACCOUNT FOR 1S

%DELAY TRACKING START.

dataNeeded = df(minPoint:((n/fps_vid)*fps_data)+ 1);

%Get list of times (in seconds) for labeling x-axis of FP plot

timeNeeded = times(minPoint:((n/fps_vid)*fps_data)+ 1,1);

%Plot the data

plot(timeNeeded,dataNeeded,'k','LineWidth',2);

%Label stuff, change axis limits and font sizes

xlabel('Time (s)');

ylabel('DeltaF/F (%)');

ylim([minD maxD]);

xlim([0 vid_duration]);

set(gca,'fontsize',30)

set(gca,'FontWeight','bold');

%Create an image frame from the figure

A = getframe(figure(1));

%Write the frame to new video

writeVideo(v,A);

frameCount = frameCount + 1;

end

%Close new video

close(v)
