- I forgot one of my AMV's is an example: 2006-05-07 22:13:11 My hellsing trailer AMV is 3 minutes and 13 seconds long so i decided to increase the FPS of it because most of the clips were fast paced to sync with the music. If you want to get a feel for the precision of HIGH FPS AMV's then check it out. The movements seem almost demonic if you ask me :P!

AHH yess.. Thanks sub0.

I forgot to mention fps in my past explanation so here goes:
The average fps for most avi compressions is 29.97fps. This is a good medium for most computers cause it plays well with all the different resolutions on just about any computer, even old ones. BUT many good things as well as bad things can come from changing the fps.
Advantages of changing fps: Well for starters, FAST MOVEMENTS on amv's arent very smooth with low fps's. So lets say you doubled, tripled, or even quadrupled the speed of a clip. The clips movements will only be allowed so much precision with 30 fps. Increasing the fps will smoothen the movement out and increase the quality by alot. Don't think that only high movement clips are effected neither. Sometimes if you slow clips down too much they seem to STOP or FREEZE for quick noticeable moments with slow fps. This can be fixed by adding more frames to make it seem like the motion is continuous. Its obvious that adding more frames will increase the potency of digital effects like fades, color changes, and other video transitions.
(Overall adding frames will greatly smoothen out EVERYTHING on the video and increase qaulity of PRECISION in the video.)
Disadvantages: I think the thing that will bother people the most is the size change. Its obvious that if you change the fps of your vid to 40 fps you increased the fps by 1/3 so the file size will increase by 1/3. Another thing to worry about is your fps and resolution settings combined. It's pretty obvious that not EVERYONE has an amazing computer with an amazing video card using a GOOD VIDEO PLAYER. For instance lets take 800x600 video with 60fps for an example. A good computer will run it perfectly cause the video card is stable with that resolution and fps. An extremely ancient computer will take that video and process it with choppy playback or freeze at times and have many other problems. (THIS ISN'T SOMETHING TO CONSIDER A HUGE PROBLEM SINCE ALMOST EVERYONE THESE DAYS HAS A HIGH END COMPUTER.)
Overall: Major thing to worry about is the fps change ratio that you are doing. Changing a 30fps amv which was lets say 50mb to a 40 fps video (The increase is a 1/3 increase). One third or 1/3 of 50mb is 16.6 repeating MB so the video size would be about 66.6MB instead with the 40fps. All so becareful with your resolution and fps ratio so you dont put too much stress on old computers.
My sugguestion: I dont want to imply much here... For any videos over 4 minutes long i sugguest you just stick to averages on everything or experiment in slight changes by yourself because of the 100mb file limit. For any vids lower then 4 minutes you should change the fps and the resolution to a maximum qaulity! DONT MAKE ME REPEAT MYSELF... EXPERIMENT AND FIND THAT MAXIMUM QAULITY! AMV.ORG GAVE YOU A 100MB LIMIT FOR A REASON, SO USE EVERY SINGLE "KB" OF IT! If you dont you can only blame yourself for the bad qaulity QC's or opinions.
All so if your worried about someone not wanting to download an amv cause of its size then thats their problem. In most cases the people that take the time to download a large amv shows that they have patience and will most likely be a good viewer anyways.
- THAT IS ALL - Thanks sub0 for pointing that out to me.

ok ill try and explain how this crap works for anyone who doesn't know or is interested.

The size of your source footage cannot be changed without changing the videos shape and proportions. Lets take the easiest example to show you this:
Lets say the source footage is 640x480... That means its a 6:5 ratio.
In most editing programs the standard is a 4:3 ratio.
The way ratio works is how proportional the width is to the height. For instance, the source of the footage is 640pixels wide and 480 pixels in height but if you render it at the 4:3 ratio or commonly known as 720pixels wide and 480pixels in height then you will be stretching the width and deforming the video from its original proportions. Basically everything on the video will be stretched and deformed horizontally.
Easy solution: The aspect ratio of 640x480 is 6:5 so anything that meets that criteria will keep the videos proportions. So for example lets take it a step up to 720x540. The aspect ratio is still 6:5, not only is it the same but you increased the amount of pixels so the video will look less "Blocky".
Advantages of increasing size: The video looks less blocky, smoother edging on the video, sharpens the video, basically everything people want it to do.
Disadvantages: The higher you go the chunkier the bit rate. Meaning for every pixel you increase, you add more data to the video per second. Old computer video cards may have problems playing in high resolutions simply because they don’t support them very well or at all... But this shouldn't be considered too seriously seeing as how most people these days have high end computers.
My suggestions: Ok try to follow me on this the best you can... Let's take a 4 minute long video for example. 4 minutes is equal to 240 seconds. Lets say the absolute average bit rate for your AMV is 200kb/sec. 240 X 200 = 48000kb or 48MB worth of video data + MB of your song usually around 5mb so overall your AMV is 53MB with that as your average bit rate. It's only 53 mb! You have plenty of room for expansion! Now most people think that increasing the bit rate is the ONLY way to increase quality which is WRONG! It does increase quality but it can only increase it so much. The best way to increase quality is to change the video's SIZE (Width/Height). Doing so will increase the bit rate automatically so that the picture still remains 100% stable. So basically your increasing the quality MORE this way then just changing the bit rate. This will make the picture look more crystal clear.
Overall... Its pretty obvious that changing the video size is a good idea just make sure you don’t increase it toooooo much cause you still have to worry about the 100mb File limit. My rule: anything over 4 minutes long should be 720x540 which is a 6:5 ratio and matches the 640x480 video in proportions. This is what i find to be the best size to quality ratio. For anything under 4 minutes long you should experiment by changing the size of the video and still keeping the 6:5 ratio or else you will deform it. Trust me this may all sound confusing but if you try it, it will all fall together and you will understand it easily. Good luck!
