Change background of video

[duccorleone]

Hi,

I need help from video editors.

I have video
http://www.youtube.com/watch?v=KVrX4Loe-hQ&feature=related

I would like to change color video from black to red. Is it possible. Thank you

[poisondeathray]

You can color/chroma key out the black and replace it with a solid layer any color (or any background) . You can do this in most NLE's e.g. sony vegas ,premiere pro or effects software eg. after effects

[jagabo]

Create a white forground image. Create a red background image. Use the black and white video as an alpha channel.

What's that, some German wording? Looks like somebody lost their frau, hehehe. I used to say "dem" too. Like wared E git dem....

EDIT: Oh yeah, I knew that, I forgot. Oops.

Sean da Paul is a Jamaican rapper.

Can it be done with free software. i dont have money to invest to programme

[poisondeathray]

Yes you can do it for free with something like blender or avisynth (both have bit of a learning curve)

e.g using jagabo's technique in avisynth

matte=FFMpegSource2("Sean Paul - Temperature - Lyrics on Screen! - YouTube.flv", atrack=-1).levels(0,1,225,0,255,false)

white=BlankClip(matte, color=$FFFFFF)

background=BlankClip(matte, color=$B22222)

overlay(background, white, mask=matte, pc_range=true)

1) install avisynth

2) copy & paste the following into notepad (in same directory as video) , change filenames & paths to match save it, change extension from .txt to .avs

3) use that .avs as input into any encoder that accepts avs scripts eg. ripbot, megui, staxrip, dozens others..

You can change the color of the background clip using these hex codes , or using levels, saturation after
http://avisynth.org/mediawiki/Color_presets

You can preview by using vdub or avspmod (f5 to refresh the preview)

[jagabo]

I did it with AviSynth and VirtualDub, both free. Somewhat advanced though. The AviSynth script looked like:

alpha=ffVideoSource("Sean Paul - Temperature - Lyrics on Screen_.flv").ColorYUV(cont_y=30)
bg=ImageSource("red.png").ConvertToYV12()
fg=ImageSource("white.png").ConvertToYV12()
Overlay(bg, fg, 0, 0, alpha)

I copy and paste the code and save as avs file. I download the video and put avs file and video file to folder.

I download the programme ripbot and I dont know what else can you help me? Thank you

Make sure you adjust the paths and filenames. Eg. if you save the video as "video.flv", you have to adjust the script to reflect that.

FFMS2 needs to be downloaded separately ; unzip the .dll and .avsi and place in the avisynth plugins folder
http://code.google.com/p/ffmpegsource/

PATH is the directory path , e.g. D:\directory\whatever

eg.

matte=FFMpegSource2("PATH\Video.flv", atrack=-1).levels(0,1,225,0,255,false)


you can preview the .avs with vdub or avspmod. If the color is to your liking, then open the avs with ripbot and encode the video

If you don't know how to use ripbot it's very simple. There are some tutorials on youtube search for "how to use ripbot"

I have video and avs file same name but I dont understand what you say about download ffm etc.

Can you give step by step guide with screen pls?

[duccorleone]

I have avs script and ripbot. What now?

[poisondeathray]

I have avs script and ripbot. What now?

Open the .avs with ripbot and encode it

It's better if you take the time to learn how to do it , but it can be confusing at first

But I can upload the video here if it helps

If you want to crop (erase) the "GiveMeThoseLyrics" that's pretty easy too

[jagabo]

Open the script in ripbot and encode.

it show error. Pls help. Thank you

[jagabo]

Did you install the ffmpeg source plugin for AviSynth?

http://code.google.com/p/ffmpegsource/

Put ffms2.dll and ffms2.avsi in AviSynth's plugins folder.

[duccorleone]

what the video if I am do it right

[Cornucopia]

Read what jagabo just told you to do. Do it first before trying again. It will not work until you do that!

OMG its so complicated just download ffms 2.17 c plugin. I am stuck. Can you anyone make me video?

[poisondeathray]

OMG its so complicated just download ffms 2.17 c plugin.

Don't download the cplugin version, use the "vanilla" version

http://code.google.com/p/ffmpegsource/downloads/detail?name=ffms-2.17.7z

[duccorleone]

in the video I do it correct? only Put ffms2.dll and ffms2.avsi in AviSynth's plugins folder and it will work?

[duccorleone]

I did it. It doesnt work

Put ffms2.avsi in the avisynth plugins folder and it will autoload

[poisondeathray]

Double check that you have ffms2.avsi in the plugins folder. FFMpegSource2 is a wrapper function that simplifies FFVideoSource and FFAudioSource with audiodub()

If you still can't get it to work this is the essentially same thing

vid=FFVideoSource("Sean Paul - Temperature - Lyrics on Screen! - YouTube.flv")
aud=FFAudioSource("Sean Paul - Temperature - Lyrics on Screen! - YouTube.flv")
AudioDub(vid,aud)
Levels(0,1,225,0,255,false)
matte=last

white=BlankClip(matte, color=$FFFFFF)

background=BlankClip(matte, color=$B22222)

overlay(background, white, mask=matte, pc_range=true)

I am confused. Can you start from beginning. Step by step pls

If you are running 64 bit windows all tools must be 32 bit, or all tools must be 64 bit, the two systems are completely separate. So if you are using 64 bit ripbot64 you need to install 64 bit AviSynth, and 64 bit ffms2.dll, and 64 bit versions of any other 3rd party filters you use. If you use 32 bit ripbot64 you need to install 32 bit AviSynth, 32 bit ffms2.dll, and 32 bit versions of any other 3rd party filters. Few filters are available in 64 bit versions so it's best to use 32 bit for everything.

Note that 32 bit AviSynth running on 64 bit Windows will be installed in the "C:\Program Files (x86)" tree.
