Tip & How-To about Philips DivX DVD Player

Banner removal from AVI using Donald Graft's Logo Filter and Adobe Photoshop

This excellent Logo Filter is usually use for adding rotating logo's to the corners of AVI files but I have found another great use if you are a bit of a wizard on Adobe Photoshop.

You can save the output frame in VirtualDub as a BMP using CTRL+2 edit it in Photoshop then overlay your edited BMP's back into the frame that you exported it from. It will take a long time to do this I have done 10 frames and the results are here I took me about an hour to create the 10 bitmaps and set the filter up correctly but the results are clear.



The Starting Frame is 61642 and I have created 10 bitmaps that start at 0000.bmp through to 0009.bmp as the origin of X:Y=0:0 for Duration of 1 frame each and loop once as you are replacing the full frame the transparent colours are not used and greyed out.

I suggest that you download his Rotating Earth and latest Logo filter and give it a go, the Earth can be made transparent (remove the back square) and last the whole AVI rotating once each frame forever using these settings.

NOTE: There are a total of 75 bitmaps, this will give one per frame starting at frame 0 if you want the earth to rotate slower increase the Duration by the desired number of frames. If you set this to 0 one frame will last the entire AVI length (so it won't rotate)




I will post my resultant AVI's very soon until then I have upped this screendump from VirtualDub to show you how good this method is if you have the time!!!




Here is a screendump showing the same frame when processed using the best alternative quicker method Delogo Removal (no longer being developed) it gives an acceptable result. You can also use several instances of the filter across different frame sequences so you can get the best results possible. By changing the Pixel aspect ratio and Power.

This filter real comes into its own this semi-transparent logos when you can use the DeBlend Masks that you can also create using Photoshop check out my tip on how to do this HERE the Logo Removal filter with UGLARM is discussed in this tip as another alternative this one you can't specify a range of frames and has to be added for the full AVI, come on Krzysztof Wojdan lets add this function to improve your filter.



WHAT IF YOU HAVE TWO RECORDINGS OF THE SAME BROADCAST

If you have the two AVI's of the same broadcast with logos banners in different places then you can also use this Filter and Adobe Photoshop to overlay BMP's



Covering the grey hatch area over the scrolling banner on the AVI using Donald Graft's Logo Filter with specific frame reference, I have included a 50% transparent mask to indicate the area masked for use with the DeLogo Filter. When all AVI's are created then use TMPGEnc v4.0 Xpress to combine all into one (VirtualDub Append AVI only works if the file audio is the same).

In the screendump belows I used a combination of DeLogo and Graft's Logo to make it easier (DeLogo works great on solid colours if you get the red mask, pixel aspect and power just right it will move it to a 99.8% success.



The 3 seconds (highlighted in YELLOW) on this join using Logo filter v1.7b2 took about 6 hours to complete the bitmaps with Photoshop (only 30secs to encode the new AVI segment with VirtualDub) the BMP's and frame settings for each change means (the nature of AVI's means that even at 25fps where the frame changes ever 2 frames it sometimes changes 3 then back to 2 or even upto 4) the animation check box can't be used which would make this so much easier. Also using one PSD for all the BMP's makes it easier to track the changes using a guide as a reference point to line up the BMP's also use drag or paste to stack the BMP's like in this example.

I'm having trouble getting .avi files to play on my TD350a.


Using the converter "AVS Video Converter 6", converts virtually video format to any other format, I have, thru tial and error converted full length movies 3+GB .mpg to ~650MB .avi. It works great!

I use the settings:
Video:
Size: 320 x 240 pixels
Bit Rate: 1200kbps
Frame Rate: 25 frames/second
Aspect: Microsoft MPEG-4
Audio:
Bit Rate: 192 kbps
Channels: 2
Sample Rate: 44100 Hz
Audio Format: MP3

The program costs $59.00, but the free download is full (but with a logo - center screen). Test it out. If it's worth it to you, buy it.
