i have some avis downloaded an burnt from around 1997/1998 ..my 1200
can play them quite ok ..if i download a avi from a later time i get a encoding error ..sound and movie ..how can i discover what encoding the avis from 1998 are ..id like to burn a few things on cd from more recent times an be able to play on my 1200..
-
VLC player can tell you which CODEC your avis are using.
Go to Tools>Codec Information
-
AVI is just a container format. You need to have the correct codec as well. The AVI's FourCC (https://en.wikipedia.org/wiki/FourCC) code will tell you which one.
-
I'm interested to know about how you are playing AVIs.
What program do you use please, and if you find the format of the videos, can you post that too?
What frame size and frame rate do you get?
Thanks.
-
As mentioned already avi is a container. Theres many, many codecs it can use.
Cinepak is probably the best compromise between speed and compression for slower hardware and can produce some decent results.
There's other options that give still better results on slow cpus, but the a1200's slow ide controller is a bottleneck so avoid them unless you use something like a fastata.
Also, make sure you have ks in fast ram as it makes a surprising difference in playback speed (especially with froggerng).
-
various movie adds ..startrek voyager previews from 1997..get about 15 frames a sec ..some play good some a bit jerky ..on my 030/50
-
You might wanna try ffmpeg to convert the avi to mpg or play directly with ffplay [http://aminet.net/gfx/conv/ffmpeg-git7df9937-m68k.lha].

most of the avis of that time generally use intel indeo video 3
-
Ffplay requires RTG/sdl and is very slow vs things like moovid and froggerng anyway.
Its really only usable under emulation.
Converting to mpeg will also be slower than using cinepak.
-
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.
-
Perhaps the '060 offering little performance increase vs a fast '030 is due to a bottleneck with the a1200's ide controller.
Would be interesting to try a more heavily compressed video and compare (or even seeing how much of a difference running from ram: makes)
-
Ffplay requires RTG/sdl
CyberGfx or Picasso96, yes; SDL, no...

110 mips a 060 ? what ?
10 mips is a 030/50 in sysinfo the 060/50 is only 38 mips
an overclocked 060/100mhz is only 77 mips
anyways that is some times faster than the 030 the difference in playing compressed videos 030 vs 060 is way notorious,seems you are drunk

videos are in cinepack because cinepack is enough fast and low quality to be played on the slow 68k cpus
but generally avi videos in the web around 1998-2000 were using intel indeo 3 or 4, much better quality/small filesize but requiring more cpu power which most Amigas could not handle
-
Sysinfo reports 38mips for my 40mhz '040, so an '060@50mhz is clearly more than that, let alone an overclocked '060.
Also Cinepak isn't restricted to video as low quality as the sample videos on OS3.9. I converted transformers3 to avi/cinepak a while back and it looks quite decent. I tried with IV as well and Cinepak is a bit cleaner. IV does however compress better, and will give better image quality the faster the cpu (doesn't drop as many frames on slower hardware, but instead will lower image quality(why it was suitable for online video in the late 90's.)
This "improved" picture quality of course only scales as far as the source materials encoding.
As for ffplay, correct me if Im mistaken, but aren't arthurs compiles statically linked against sdl?
Im not aware of a native backend for it against cgx/p96

what program did u use to convert ?? ..i use freemake video converter ..for most things ..just works easy ..but tried avis but thats when i get get codec errors when i try to play on a1200
-
I used Virtualdub.
Bare in mind however that you'll need to first install Codecs for Windows to be able to read the different filetypes of the videos you're trying to convert (remember that avi is a container type, not a codec).
Virtualdub by default converts to assorted legacy Codecs (including cinepak), but doesn't read many "out of the box", and instead relies on Windows Codecs (different to what video players use).

no no
you are fake you are a liar
sysinfo on a 040/40mhz reports only 30 mips
a 060/50mhz does 38 mips in sysinfo
all of this can be verified easily in the web

no no

And you believe those figures? Because according to that, a 40 and 60 are almost the same speed per mhz, and that's obviously nonsense. 60s do need properly optimized versions of software to really be faster, though.
Basically it doesn't matter what Sysinfo says, because Sysinfo isn't a good benchmark. Use good benchmarking software, and even then you have to be careful. Different 68000 family processors need different optimizations to really run efficiently, and a one size fits all benchmark like Sysinfo that also doesn't do real life tests (hugely important!) is basically a crappy benchmark.
People need to stop relying on Sysinfo, period.

Haha, yes Im fake, not real at all. My posts are merely figments of your imagination and/or doctored with photoshop.
Seriously though, either pull your head in and stop acting like a pork chop, or keep digging so I can enjoy the laugh.
I dont need the web to verify what my own computer tells me :)
For the record, I dont trust sysinfo anyway, but that wasn't the point.

Very nice.
If we weren't both fake I'd be impressed :P

I'd guess 66.

Are you doomy?
sysinfo,or as many Amigan's call it sysMISinfo was not designed for 060(at least not until a recent updated version from another person who took it over). Also many of the things it reports are not accurate.
-
The bottleneck on playback of AVIs could be from HD transfer speed or memory access.
Anyway...
From Wiki on 68060:
- ~88 Mips @ 66 MHz
- ~110 Mips @ 75 MHz
- ~36 MFlops @ 66 MHz
-
Is FroggerNG only for amigas with FPU? It prompts for one when it starts up but I couldn't see it in the requirements. Or is there a non-FPU version please?
-
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.

yes the 040 and the 060 are same speed per mhz , ie idem core excepting the 060 have a faster FPU
an overclocked 040/50mhz is 38mips idem like the 060/50mhz
and yes SYSINFO is the best benchmark,that's because was always used for comparison
now if ppl like you who have a 060 like to use benchmarks like sysspeed because they make you feel you have a faster CPU is a different history

you are a liar and fake everybody knows that a 040/40mhz is only 30 mips on sysinfo

and this is for the 060 fools ....real screenshots of 060/50mhz
you can see is only 38mips, some ppl here still think that a 060 performs like a core i7

No, they're not the same speed per mhz, and I'm pretty sure of that. You're basing this on Sysinfo, and that's just plain wrong.
and yes SYSINFO is the best benchmark,that's because was always used for comparison
No, it's not the best benchmark. Also, how much something is used has no effect on it's quality. Not to mention that benchmarks in general are tricky.
now if ppl like you who have a 060 like to use innacurate benchmarkslike sysspeed because they feel they have a faster CPU is a different history
I don't have a 60, nor do I have a 40 (I have a 30). What you're saying is just highly unlikely. I already explained how you can get more performance from 60s by using proper optimizing techniques. Techniques that only work on 60s. One size fits all benchmarks like Sysinfo don't take these features in account.
Anyway, if you want to believe Sysinfo, go right ahead, just don't expect everyone to agree with you.
-
Hah, I could get 060/50 to make nearly 60 mips on Sysinfo - just running on suitable RTG screen with a higher refresh...
-
@laserback
Ah, I see you opted to keep digging a hole and making people laugh. Very good, this site needed more comic relief.
As for your claims that an '060 is much the same as an '040 at the same clockrate, care to amuse us with an explanation as to why real software performs so much faster on even 50mhz '060 than a 40mhz '040?
Doom, quake, pc-task, photogenics, even dnet clients. Its not just fpu stuff either. Imagine3d no fpu version shows big speed-ups.
-
It's so easy - 060 has 2 integer units and needs code that uses both to get the full speed out of it. Sysinfo runs just on one unit.
-
@zipper
Careful, lest you want to be deemed fake. :)

uh yeah
I forgot the 060 is a dual core
-
uh yeah
I forgot the 060 is a dual core
Having two integer units or two cores doesn't mean the same thing. A 60 can execute multiple instructions at the same time if they're in the right order. This has absolutely nothing to do with running multiple threads at the same time.

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..

Very nice.

Yes, 80MHz. Thanks for your nice comment.
The 040@40MHz is a nice CPU, but it's slow next to an 060.
Everything I post here is fake though; pictures, words... I'm just a wreckless fool! :laugh1:

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.

To LaserBack:
Instead of calling people fakes, and saying dual core all the time, you could read up on the 60 specs: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MC68060
And here's a 60 diagram where you can see the two integer units pOEP and sOEP:
(http://cache.freescale.com/files/graphic/block_diagram/MC68060diagram.gif)
You keep going on about Sysinfo. That bench mark isn't accurate. Get over it, and accept the facts. And no, 60s aren't dual core, they have two integer units, NOT TWO CORES. Is that so hard to understand? No one ever said anything about 60s having two cores except YOU.
You deny plain facts that have been know by skilled 60 assembler coders for over ten years now. Stop being so stubborn, and throw that damned Sysinfo in the trash. It's NOT a good bench mark for 60s, period.
Anyway, believe what you want, it doesn't matter, because your beliefs don't change the facts.
-
You keep going on about Sysinfo. That bench mark isn't accurate
sysinfo is 100% accurate
is not accurate only for all the blue pill 060 fools
and of course the 060 is not a dual core cpu ,I was joking you can't detect sarcasm
2 integer units ? wtf ?: they are in your imagination lol
-
sysinfo is 100% accurate
No, it's not. No benchmark is 100% accurate, and if you knew what you were talking about, you would know this.
2 integer units ? wtf ?: they are in your imagination lol
No, they're not. They're a well documented part of Motorola's 68060 design and implementation. Didn't you look at the diagram I posted? Why don't you download Motorola's official 68060 documentation and see for yourself.
Really, you either have no clue whatsoever about what you're saying, or you're just trolling.
Anyway, I'm completely done with this crap. If you can't be bothered to learn anything, then that's fine with me. However, I do have a problem with you calling people liars and fakes, while YOU are the one who's completely and utterly clueless. And if you're just trolling, then grow the hell up.
-
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.
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 ..
-
Its actually pretty simple.
No need to install cinepak codec, virtualdub can deal with it by default.
Just open the file you want to convert (this is the part you may need to install a windows codec or two for), then select the video compression, select cinepak, then adjust your audio to suit (eight bit mobo is probably a good idea for a slower cpu). Adjust your color depth to sixteen bit, then save as legacy avi.
That's all there is to it.
Im not infront of my windows machine at the moment, so I couldn't remember menu names, etc., but with the above description and even a little bit of computer literary you'll be good to go :)
To be honest, having to have a look around the software a little will better help a person to learn than having their hand held all the way through anyway. Besides that, it really is very simple once you have the basics.
-
ok following your instrutions ..couldnt find 8 bit audio ..an no sign of legacy avi ..just saved as old type avi ..see how it goes ..i did find a 10 min avi from my collection on a cd from 1996 ..it played ok ..was full screen even ..bit jerky an colours were not quite right ..but who knows ..im persistant..

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.

thanks i did get a full episode of startrek converted to avi ..an it played from my usb on my 1200 ..a bit slow ..but didnt wanna burn a cd till i thought id get a working copy ..no sound yet ..so ill try your suggestions on how you did it ..c how it goes ..only program i used before was freemakevideo converter ..brilliant program ..can turn a mp4 into anything almost ..or easy vcd ..they basically do everything for you ..

thats outstanding ..afraid best i could get is 160 x 240 ..with sound it gets a bit lost but plays ok ..afraid the colours get lost ..good effect for my 1200/030 ..i used action player ..cyberavi users lots chip memory so large avis it just wont play ..i got over 90 meg fast ram free but stuck with 2 meg chip limits ..
how do u get it to play in ham mode ?
-
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.
