AVI question

[NovaCoder]

Most of the AVI video files included on the AmigaOS3.9 CD seems to have the following details:

Video:
Codec = Cinepak (cvid)
Size =  320 x 240
FPS = 20

Audio:
Codec = PCM (Uncompressed)
Rate = 22050Hz
Channels = 1 (Mono)
Sample = 16 bit

Have in mind that although the width is 320 pixels, the height varies in order to preserve aspect ratio.

This could at least be a starting point.

Yep a good starting point.

I've noticed that those videos are very low quality, even if you watch them in a Window on Windows (confused?)

One strange thing that I noticed with video playback on Classics, if I play the same OS 3.9 video with an 030 and then an 060 the playback speed is not much better.   Considering the increase in MIPS (from 10 to 110), you'd expect a bigger improvement?

I've also played around and converted a few of my own clips to AVI but haven't got it working very well yet.

I thought I'd give Virtualdub another try with CinePak and got a reasonable result, I'll have to see if I can tweak it further.   The audio is very low, not sure why.

im assuming  u got a 060  playing that avi  ..i dont get nearly as good results  
smooth enuff  but looks more like 16 colours  on my  030 machine half screen  mov files  look better using action  i use cyberavi to play avis ..mpegs dont seem to like me  so far not many play for me or are way jerky.. ..lets say  i have a mpeg  or a vcd  of a movie  an want to play it as a avi on my a1200 ..how  do i do it  ..never used virtual dub etc..

Yep 060, same speed as Paul's

MooVid is the best thing for playing AVI's on AGA, you can use the HAM8 mode called 'Storm Dither' for the best looking results (16bit on AGA!).   The AVI player bundled with 3.9 called Action is actually MooVid in disguise.

Virtualdub seems to be the best tool to use for creating the AVI's (use CinePak codec), I've still got to fine tune it a bit to improve the playback.....watch this space.

Saying all that though, you're not going to get very good results with an 030, it's just not powerful enough I'm afraid.

could you please do a quick how to  with virtual dub  to making avis  capable of being played on amiga  ..ive downloaded  the program  ..how do i add the codecs(cinepak)  i need  an how do i set it  up to copy an convert a movie  to a avi..had a quick look a bit lost ..i downloaded the latest version ..

Ok, grab a small AVI 320x240 for example (or choose the resize filter) within virtualdub under the (video menu).   Under the Audio menu, select 'conversion' and set that sucker at something like 11025Hz in 8bits.   Set both Video and Audio to 'full processing mode' and that's about it I think.   That's all I did to produce this movie anyway.

I'm going to see if I can improve this ouput tomorrow if I get the time...

thanks  i did get a full episode of startrek  converted to avi  ..an it played from my usb  on my 1200 ..a bit  slow  .

Cool, I just (finally) got the intro to ALIENS running well on my A1200.

I'll try and upload a video tomorrow

I had another go, this is as good as I can get it I think.

You just need to find the last version of MooVid and then read the guide that comes with it, basically you change a couple of ToolTypes and set it up for HAM8.
