ParanoidLittleMan Posted September 25, 2012 Share Posted September 25, 2012 (edited) I made couple short videos with audio : http://atari.8bitchip.info/HCPL.ZIP Used Photochrome 4096 color mode, fullscreen, 12.5 fps, audio is 25033 Hz, mono. It is very demanding considering CPU time, disk space, loading speed. Max some 6 sec. playback at once is possible. Requirements: STE or MSTE with 4MB RAM , 3.5 MB free RAM. Hard disk. TV/Monitor capable to work at 50Hz (PAL). May try with some emul. Steem, Hatari. On ST will be no sound, and less colors. Too much ? Well, it is still not enough for some contigous playback :-) This could be base for enhanced Space Ace. Contigous playback with 4096 colors ? Extremely demanding, especially at 25 fps and fullscreen. I have some ideas how to achieve it on STE. But it will not work with UltraSatan, to say ahead. Only with Cartridge or IDE IF + little mod. + raw hard disk access and special SW. If it will work some day, expect aprox. VHS quality - there will be noise too, audio quality similar to mono, analog VHS. Sharpness may be better than average VHS. About 45 min on 4GB.

fedepede04 Posted September 25, 2012 Share Posted September 25, 2012 got it to work under STeem, it was fun to see, good work Quote Link to comment Share on other sites More sharing options...
+DarkLord Posted September 26, 2012 Share Posted September 26, 2012 Just curious, are you using Doug's new Photochrome stuff? He's released a few updates here lately. (and really nice to see him back!). Quote Link to comment Share on other sites More sharing options...
ParanoidLittleMan Posted September 26, 2012 Author Share Posted September 26, 2012 Yes. He even did some things on my request. Best thing is that can do conversions fast on PC. We can expect more updates of Photochrome in near future. Quote Link to comment Share on other sites More sharing options...
OBO Posted September 27, 2012 Share Posted September 27, 2012 (edited) hmmmmm I'm suddenly interested in knowing how to do it myself. I definitely want to have the loop from this video from 1:02 to 1:04 looping when i'm not using my ST/TT http://www.youtube.com/watch?v=VF7cO4t0o9c Edited September 27, 2012 by OBO Quote Link to comment Share on other sites More sharing options...
ParanoidLittleMan Posted September 28, 2012 Author Share Posted September 28, 2012 Well, it needs diverse SW: you need to convert your video (A/V) source into picture sequence + extract sound too. Of course, with some conversions. In this case we need resize to 320x200, with some cropping before it, by need. And only every second frame. Not hard with Virtual Dub + AviSynth Later is not necessary for AVI, MPG src. But certainly, there are other programs capable too. You need to convert audio to mono, 8bit, 25033 sample rate. Before it may be necessary to do time stretch by factor 0.95904 if video is 23.976 fps - because we play back at 25 fps. Then comes Photochrome on its - converting pictures (png or tga format) to PCS. After all it need my special, simple SW to compose file good for STE playback. Since you need only 2 secs, we can go even on 25 fps - then picturise every frame. Not so hard after you did it already Quote Link to comment Share on other sites More sharing options...
OBO Posted September 28, 2012 Share Posted September 28, 2012 (edited) Ok I do not need the sound ! (Having the "Croooooow Crooow Crooooow" looping sound would surely make me go mad) Hmm.. maybe the whole Robot Roll Call sequence could fit ? I'll see too to try to create a video to use with Didier Mequignon's Mplayer for STE/TT. Edited September 28, 2012 by OBO Quote Link to comment Share on other sites More sharing options...
ParanoidLittleMan Posted October 4, 2012 Author Share Posted October 4, 2012 I made 2 demos of contigous playback. Both are 1 min, 320x160 px. May try in Steem or Hatari. http://atari.8bitchip.info/Play1min.rar - 40MB. http://atari.8bitchip.info/HCPL.rar - 36MB. Read supplied txt about possibilities of running on real STE.

+DarkLord Posted October 8, 2012 Share Posted October 8, 2012 Interesting stuff, keep up the good work. Just waiting till I can play everything on my PAK board at 32/40/50mhz with an FPU. Quote Link to comment Share on other sites More sharing options...
+DarkLord Posted October 8, 2012 Share Posted October 8, 2012 BTW, downloaded that sample Avatar clip - very impressive! Quote Link to comment Share on other sites More sharing options...
ParanoidLittleMan Posted October 8, 2012 Author Share Posted October 8, 2012 Avatar flight scene was easy case. But not all material is good for PCS - even in slow, m3 mode quality is not so good. Scene at fire and large skull looks very bad after conversion. As I see, dark scenes never will look good. Btw. some accelerators. PAK boards would be good for depacking compressed video, but real brake is slow RAM and video in Atari STE. Quote Link to comment Share on other sites More sharing options...
+DarkLord Posted October 8, 2012 Share Posted October 8, 2012 Don't know how much of a difference it makes, but in getting my STacy ready for the PAK board, I replaced the RAM board that came with it. All 4 megs of RAM are at 80ns now. Hmm, as we've discussed, even with a good accelerator, there will probably never be audio with anything but the STe, Mega STe, TT, Falcon, correct?

+DarkLord Posted October 9, 2012 Share Posted October 9, 2012 Downloaded the LAV2 app and played the SpaceAce clip with it on my PAK equipped STacy. No audio of course, but the video played well. Very nice screen size and good speed. I would imagine that any movie could be converted that has sub-text and you could still watch them then! (Pan's Labyrinth for example). BTW, is that one clip on your site from Firefly - Serenity the movie? It looks like Wash. Quote Link to comment Share on other sites More sharing options...
+wood_jl Posted October 9, 2012 Share Posted October 9, 2012 I just watched the AVI. That's awesome! It's great to see the ol' ST get pushed like that. I must have had a 486DX2/66mhz before I saw anything like that, on my PC. Quote Link to comment Share on other sites More sharing options...

To make everything faster, faster RAM chips are not enough. You need faster MMU, Glue, etc. DMA audio of STE is really useful - it is simple to programm, and slowdowns not at all. In theory, you can do some sound on ST during playback, and some players solved it. But quality is pretty low. Additionally, it slowdowns pretty much, and we are already on limit. I have some ideas about sound on ST, but it would take to much time to code, test, while qulity never will be good. So, better focus on other things - and there is a lot. Subtitles: it is easy to add with Virtual Dub. But because low output res, it will take more % of screen than it is usual with modern players. Anyway, I will do something for test. Yeah, from Serenity. Wash or Walsh ? Edited October 9, 2012 by ParanoidLittleMan Quote Link to comment Share on other sites More sharing options...
+DarkLord Posted October 9, 2012 Share Posted October 9, 2012 Understood. Looking forward to that test...and thanks. Umm, you know I always thought it sounded like they were saying "Walsh", but in the Wiki it says "Wash". Got me. Quote Link to comment Share on other sites More sharing options...
ParanoidLittleMan Posted October 11, 2012 Author Share Posted October 11, 2012 Added 2 min AV with subtitles, on same page: http://atari.8bitchip.info/movpst.php This is capturing from Mega STE (my STE broke yesterday). About 14MB AVI. If someone wants Atari file for Steem/Hatari, let me know, but it will be about 100MB. Quote Link to comment Share on other sites More sharing options...
+DarkLord Posted October 11, 2012 Share Posted October 11, 2012 Just downloaded the subtitled version. Nice. Will it run on an ST also, or does that clip only run on the STe/Mega STe? (not near my Atari's right now) Thanks. Quote Link to comment Share on other sites More sharing options...
OBO Posted October 11, 2012 Share Posted October 11, 2012 Hi, I gotta check what happens when I run this on TT... I think the TT speed completely destroys the hi-color mode, right ? Quote Link to comment Share on other sites More sharing options...
ParanoidLittleMan Posted October 12, 2012 Author Share Posted October 12, 2012 I gotta check what happens when I run this on TT... I think the TT speed completely destroys the hi-color mode, right ? Hi-color needs 68000 at exact 8 MHz. And you have some better screen modes on TT (with more colors) already. So, player should use them.

It may run on ST, without sound, and with less colors. But you can not run this with usual hard disk adapters - they are not enough fast.

OBO Posted October 12, 2012 Share Posted October 12, 2012 better screen modes on TT (with more colors) Well, not that much. By default the most colored one is the 320x480/256c mode, but the pixels are not squared, and by default the GEM display is "streched". FYI, 320x480 is the original iPhone's screen resolution...

ParanoidLittleMan Posted October 12, 2012 Author Share Posted October 12, 2012 I know it. Still, using part of 480 lines could give relative good AR. Something like 320x320 px. And you need to prepare video for that not squared pixels too. And without some packing, data rate will be too high. But no CPU power for depacking, I guess ... Not really promising.
