Help with adding the watermark again to the video

The web video script that I'm using, and trying to modify, works successfully integrating a watermark in the upper left corner of the video file, (so that when it's downloaded, the watermark stays on the video). In the ffmpeg php file code below, the watermarking starts with this line 

$watermark_image_full_path = "watermark.png";

at line 275 (out of 504 - about halfway).

I am wondering if there might be a way to make the watermark also display briefly in another location on the video again, maybe halfway through, when playing it.

Take a look at the documentation for the overlay filter.

You can position the overlay using the x/y parameters. One of the examples demonstrates how to do a "sliding" overlay by using an expression that returns an offset or NAN. You can borrow that concept to make an overlay that appears when the "t"ime is when you want.

However, in order to know when it reaches the middle of the video you'll need to know how long the video is... You can also use that length to decide whether you should put the watermark in - perhaps the video is too short to make it worthwhile.

Much thanks for your reply. I did not write the posted code, but based on what you provided, would you say I would need to integrate this link example: 

overlay=x='if(gte(t,2), -w+(t-2)*20, NAN)':y=0

into this line of code in my posting?: 

$ffmpegCommand =''.$ffmpeg_b.' -y -i '.$video_file_full_path.' -i '.$watermark_image_full_path.' -filter_complex "overlay=10:10,scale=640:-2" -vcodec libx264 -preset '.$pt->config->convert_speed.' -crf 26 '.$video_output_full_path_240.' 2>&1';

if I'm correct with that, then I'd somehow replace/integrate this: 

"overlay=10:10,scale=640:-2"

with this?: 

overlay=x='if(gte(t,2), -w+(t-2)*20, NAN)':y=0

 

because I'm not clear on what this means: 

"overlay=10:10,scale=640:-2",

I don't know if it should stay in or be modified. Any additional guidance is appreciated

You want two overlays, right? One for the whole video and one shown briefly around the middle? So you shouldn't be "replacing" anything. Should be adding. And it's possible you may need two separate ffmpeg commands for the two watermarks, I'm not sure.

That expression you saw is the example, yes, but it does not do what you want. You need to come up with a new expression that produces the correct x/y values: whatever number around the midpoint of the video and a few second after, or NAN if it should not show. That means some kind of condition where if the video is between the midpoint and midpoint+some time then you return a valid x/y but if not then you return NAN.

According to the documentation, scale=640:-2 will scale the video to width=640 and height=automatic based on width but divisible by 2. scale=720:-4 would be width=720 and height=automatic divisible by 4.

Thanks again for your assistance.

So, in my current original posted line of code, I don't see any coordinates. However, when it processes it places the logo in the top left corner, which is good.

So, based on the linked documentation, I believe I've added a second instance of a logo showing up after 20 seconds. If I'm incorrect please let me know. 

And any help I can get with adding coordinates to the center for the 2nd logo is appreciated.

Here my current modification: 

 $ffmpegCommand =''.$ffmpeg_b.' -y -i '.$video_file_full_path.' 
-i '.$watermark_image_full_path.' -i '.$watermark_image_full_path.'(t,20)
-filter_complex "overlay=10:10,scale=640:-2, overlay=10:10,scale=640:-2,"
-vcodec libx264 -preset '.$pt->config->convert_speed.' -crf 26 '.$video_output_full_path_240.' 2>&1';

If I could find where to edit my previous message here, I would have changed it to say that, upon some more research I see that 10:10 puts the watermark 10 pixels from the top and 10 pixels from the right, correct? So, I added the code above and ran an upload, which appeared to upload, but nothing there when I try to play it.

Any additional help is welcomed.

-i is an input file. I doubt you created a second watermark file named "watermark.png(t,20)".

You also seem to have copied and pasted the overlay and scale filters, without any changes to them. That's not right.

You need to spend the time it takes to understand what this command does. What "overlay" and "scale" are.

Thanks for your reply.

Yes, I copied them because I'm trying to add the two same logos with the same code line, as an example showed in the documentation.

So, my latest (unsuccessful) attempt is: 

$ffmpegCommand =''.$ffmpeg_b.' -y -i '.$video_file_full_path.'-i '.$watermark_image_full_path.' -i '.$watermark_image_full_path.'-filter_complex "overlay=10:10,scale=640:-2, overlay=10:10 'if(gte(t,15), -w+(t-2)*20, NAN)',scale=640:-2,"-vcodec libx264 -preset '.$pt->config->convert_speed.' -crf 26 '.$video_output_full_path_240.' 2>&1';

any additional guidance is welcomed

Ok, thanks again for your help.
This has succeeded: 

$ffmpegCommand =''.$ffmpeg_b.' -y -i '.$video_file_full_path.' -i '.$watermark_image_full_path.' -i '.$watermark_image_full_path.' -filter_complex "overlay=10:10,scale=640:-2, overlay=180:180:enable=between(t\,5\,5+2),scale=640:-2" -vcodec libx264 -preset '.$pt->config->convert_speed.' -crf 26 '.$video_output_full_path_240.' 2>&1';

Yet, on the uploaded test videos, the first watermark in the upper left corner looks small and unsharp, but the 2nd watermark, that displays in the middle after 5 seconds, looks to be the correct size, and sharp.

Any ideas on how to improve that will be welcomed.
