Help with Avisynth / InpaintDelogo for a Windows 7 user

[Marty-K]

Hi there

I just wondered if anyone can point me in the right direction of the most effective way of removing logos / watermarks from mp4 videos without reencoding and losing quality?

I use Windows 7 and have been looking at the methods people use using InpaintDelogo which I assume is with Virtual Dub?

I have not yet been able to work out how to save mp4 files using virtual dub / virtualdub2 as direct stream copy to avoid loss of video quality (for exporting) it does not seem to let me and throws up errors.

Or can InpaintDelogo be used using ffmpeg for mp4 without the need for Virtual Dub?

What I am trying to do is find the most accurate and effective way of removing a water mark from a handful of videos I have. I think the water mark is always in the same location on every video and lasts for about 7 or so seconds.

If I could just have some guidance on how to do it (Using Windows 7) I would be really grateful and having read various posts on here it seems having Avisynth with InpaintDelogo is the main method of the removal of water marks. Unless there are others which are easier and equally as effective?

Thank you all in advance.

EDIT: Some of the images in that thread are not now showing for me in the UK (problems with UK government and showing images without age verification nonsense).
I switched to Switzerland via VPN (Proton) and still cannot see them.

Thanks for the link. I also cannot see those images here in Australia.

I am hoping there will be information on that thread for someone who has never used Avisynth before (me) who uses a Windows 7 machine.

I think imgbox have probably removed the images and its not a matter of viewing it from a different IP as to whether or not it displays the specific images.


Thanks though for getting back to me on this

same here in Iraq, so I think it's the image host problem

Ironically, we used to see the west as freedom Pioneers, but nowadays seems the west is worst than us, I believe this is due to immigration, and I am against immigration and asylum except in rare cases, also seems nowadays the host country most of the time will get the worst people from the immigrants (We are not in the days of America discovery)

Welcome to communist the west my friend.we are becoming the great firewall of China amongst many other things (immigration included)

1. You will have to re-encode. You cannot avoid this because once you alter the video by removing the logo, you have created new pixels, and to create video from those new pixels you must re-encode.

2. Given the steep learning curve for AVISynth, and given that you are obviously new to creating video, you would probably have a better chance of getting things done by using VirtualDub with the old Delogo plugin. I created a tutorial 15 years ago:

Hi John

Thank you. I actually watched your video earlier on YouTube. Thanks for providing it. I got to the end part of the video but was unable to export it as an mp4. Importing the mp4 was fine because I was using the ffmpeg plugins but if you were to use your method with an mp4 file, what settings would you apply when exporting it for both audio and video as I realize direct stream copy won't be possible

Cheers

What version of VirtualDub are you using? Versions since about 2018 have the ability to encode an MP4 directly.

Thats the version I am using John.

When it comes to export then can I just choose file>export>stream copy?

Or would I need to adjust things on full processing mode (compression) for both audio and video after following your youtube guide?

[johnmeyer]

You go to Video-->Compression and choose

x264 8bit - H.264/MPEG-4 AVC codec

You could also choose 10 bit.

You then go to File-->Save As and save your video. The encoding will start at that point.

Use ChatGPT to get a tutorial on how to set the parameters in the Configure section, and also how to go through the rest of the process.

Thank you John I will do.

Having tested your method I am satisfied with the results. It has left a blur but its blended in well. Thanks for this John
