Does anybody have heard about the following problem ?:
When I want to create an *.avi from a premade track the result is terrible with blur in the screen during playing of the movie specially during movement scenes (hee oyeh that's about all the time in lock on afcourse if you do it right ! it is not only during joystick movements it's like there is lots of water on my screen!) My PC should be powerfull enough ? and there are now anti virus or anti spam programm's running in the background Hey what's left is all system and I'm not even able to kill those ! system: pentium 4 2 Ghz with 1 Gb ddram and Ati-radeon 9800 pro 128 mb (hardrive space 150Gb left !) latest lock-on patch installed and latest drivers for just about everything (did I miss one ?) movie is saved in same directory as lock on on separate disk (F  so NOT being windows disk (C please help me .... |

First of all I assume that when you play LockOn everything looks good and you have no problem. Second I assume that when you play other peoples videos they look good. And I assume it is just your own movies that come out bad.
QUICK RENDERING OF ENTIRE TRACKFILE ========================================= CODEC choice is important. The CODECs you have installed need to be configured. If you have LockOn Flaming Cliffs you got a very good CODEC named XviD. In your case you have a single complete trackfile that you are happy with and you want to render the whole thing. In this case DO NOT use uncompressed RGB format, use a CODEC so that the file get shrunk. If you render a whole trackfile uncompressed you can get overflow in the file and it will look like ****. Next, your harddrive might not be able to pump that much data to the media player and the video will end up choppy and garbled cause not enough data is coming to the media player. You must use a CODEC. Before you render the trackfile you go to the options section and maximize all graphics settings. You should also go to the Windows control panel and start the program that controls how your graphics card operates and add anti-aliasing 4x or 6x, maybe avoid anisotropic filtering, skip all other options too, anti-aliasing is the more important one. Now you will render the movie at max of what your graphics card can handle so it will look pretty. You need to render the movie at a good resolution and frame rate and choose the codec. Configure the XViD CODEC by in the WIndows Start Menu search for XviD and choose "Configure Encoder". If you have LockOn 1.02 you can get the free XviD codec here: XviD The best option for XviD seem to be: Profile Level: (unrestricted) Encoding type: Single pass Target quantizer: 2.00 Quality preset: General purpose IF you want to make the file smaller use target quantizer 4.00 but now the video will start to have noise in it and it will get worse as you increase the quantizer but on the other hand the file will get smaller and smaller and more easily distributed to friends. Then load your trackfile and select "Record AVI". Now you get a panel on the right side where you can select resolution, framerate, and CODEC for video and audio. Look around in this panel and familiarize yourself. in "VIDEO METHOD" select the XviD CODEC. Now start render the file and go to sleep and look in the morning. VIDEO EDITING ================================== Usually if you are going to edit the video you use a lossless video CODEC so that when you look at the video it is a mathematically perfect copy of what LockOn sent into the CODEC. Usually these file are like uncompressed RGB in that they can not be played directly by a media player, this time it is not the harddrive that is the problem but your CPU that cannot decompress the information fast enough. But it is good to know that it takes less disk space and you have not lost any video quality. LockOn -> CODEC(lossless) -> File VideoEditingTool <- CODEC(lossless) <- File VideoEditingTool -> CODEC(lossless) -> File File -> CODEC(lossless) -> CODEC(XviD) -> DistFile Freeware Video Editing Tools that cost you nothing can be found here: VirtualDub AVIsynth ######AVISynth have problems with all lossless CODECs but one, and that is this one: Lagarith EDIT: Forget the above. I seems to me now, that LockOn runs the CODECS in a bad way perhaps not supplying enough information to them? Cause no file rendered in LockOn using lossless codec can be opended by AVISynth. But all it takes is to use VirtualDub and select "fast recompress" and recompress to exactly the same lossles codec and now AVISynth can open the video file. So VirtualDub does something right that LockOn does not do. Therefore the other lossless CODECs might work too. Now you can spend some time on the AVISynth site and learn how to program AVISynth. AVISynth scripts may look like this, filename "test.avs":
# The FPS I am using in the file
FPS=20
# Time for blending two clips
TRANSITIONTIME=FPS*2
movieclip1=avisource("movie1.avi")
movieclip2=avisource("movie2.avi")
music=wavsource("music.wav")
movieclip1edit1=FadeIn( movieclip1, FPS*6, 0, FPS )
movieclip2edit1=FadeOut( movieclip2, FPS*6, 0, FPS )
part1=Trim( movieclip1edit1, 0, movieclip1edit1.framecount-TRANSITIONTIME)
part2=dissolve( movieclipedit1, movieclipedit2, TRANSITIONTIME, FPS )
return AudioDub( part1 + part2, music )
You can read on the site and take it step by step, anyways it is freeware and you dont pay anything for the things I listed above. Then you open this AVS script in VirtualDub just like if it was a AVI movie file. VirtualDub then uses AVISynth as a frame server that feeds VirtualDub each frame. In AVISynth you can do fadein fadout transitions cropping ... all kinds of crazy things, and you can import VirtualDub filters so that AVISynth can do just what VirtualDub can, and if that is not enough you can go hunting on the internet for all kinds of weird effects. I wrote this long since I was unsure of your exact problem, and that maybe this will be a hint to others. Feel free to ask more questions, as long as they are not about tools you pay for.

 a thousand times You describe exactly the problem and hopefully (i think completly) the solving matter I will look in to this immediatly ! I made a movie (before using your info) uncompressed one that showed in WM Player four scenes at once ! (size ~4Gb)and a compressed one that looked better but still had all the blur in it (size ~333 mb) Dvix codec crashes it shows a separate screen that ask for some settings (that can't be set) and lock-on hangs-up Thanks again now I'll use your info! {p.s. You would think that microsoft should change WM player or manufacterers come up with a solution so that hardware can handle large files sinds modern files and harddrives are more and more capable of handling Gb file sizes ??!!$#%%$ } |

My first movie is indeed OK now althow I definitly have to do something about the size (~1,2 Gb for 20 minutes using 60fps and 60% quality!)now I tried 25 fps and 25% quality this gave 800 ++ Mb that's better afcourse the 20 minutes is a little long next I'll try to edit thanks for your help ! it was indeed a codec problem

Set the quality to 100%, I don't understand if this really affects anything.
But as I said you need to configure the Codec, try step up the quantizer to '4'. Also, if a lot of things are changing in the picture from one frame to the next there is not much the CODEC can do. Steady camera. I think you should be able to get down to 600MB. 20 min is a long video. Is it interesting all those 20 minutes or can you start doing some cutting in the video? |

with 100% quality and 100 fps and some camera position changings I start to see frames missing
eq bits of the track have gone missing. With the maximum of 5 minutes flight time I've put my self to (that is afcourse only for making video's !) all movies are now below 600Mb so that's better. Now I'll start to use max. 60fps and 60% quality because there is not much difference to see between 100fps and 100% or 60fps and 60% maybe this will solve the small gaps in the video or..... I've heard that there could be problems occuring when using to much camera switching positions during the clip ?

I guess there can be if you make several small clips that you join together later. I DON'T know but I guess there could be problems.
Too high framerate may cause you to break the max allowed bandwith for the Mpeg4 encoding mode you set or limits set by the MPEG4 standard, it is just a guess why you loose frames if you actually has lost any that is. For example open the video in VirtualDub and single step the frames to see if any really are lost. Otherwise the simple explanation is your computer cannot hack it to decode high quality MPEG4 video at 100 FPS and that the effect you describe is the same I see on my computer when I am encoding a video in the background or doing some other heavy job whilst at the same time trying to view a MPEG4 video in windows movie player, the player don't get the CPU power it needs and therefore throws frames away and jumps to the next key frame or GOP just to catch up and get in balance again. But as I said open the video in VirtualDub and single step it to first make sure the frames are actually lost and gone from the encoded file. Then you know what conclusion to draw from that information. |
