I'll try to do an estimate in more detail. Let's suppose we have code that is memory limited (takes every second mem cycles) e.g. a move.b d(Ax),(Ay)+ sequence for texture scaling. So CPU only would be Code:
0 4 8 12 16 20 CPU C - C - C - C - C - C - C - C - C - Code:
0 4 8 12 16 20 CPU r r r C - r r r C - r r r C - r r r C Blitter B B B x B B B B x B B B B x B B B B x Code:
0 4 8 12 16 20 CPU r r r C - r r C - r r C - r r C - r r C Blitter B B B I B B B I B B B I B B B I B B B I no idle, 4 bpl dma Code:
0 4 8 12 16 20 24 Disp D - D - D - D - D - D - D - D - D - D - D - D - CPU r r r C - r r r - C - r r r - C - r r r - C - r Blitter - B - x - B - B - x - B - B - x - B - B - x - B Code:
0 4 8 12 16 20 24 Disp D - D - D - D - D - D - D - D - D - D - D - D - CPU r r r C - r r r - C - r r r - C - r r C - r r r Blitter - B - x - B - B - I - B - B - x - B - I - B - B So after that back-of-a-slightly-bigger-envelope calculation, I'm not sure if it is worth it; but it is a very small modification to the code, and you can always check with the winuae dma debugger, or just benchmark. And please excuse me for clogging your thread with lengthy posts containing untested ideas. |

I did the same kind thing to increase performance of my Quake 2 port to AGA. If you use a Doom style status bar at the bottom of the screen and a smaller one at the top then you could get away with a 320x180 or maybe 320x160 pixel 3D viewport. Last edited by NovaCoder; 08 November 2019 at 01:10. |

So the AB->D no-display example really becomes: Code:
0 4 8 12 16 20 CPU r C - C - C - C - C - C - C - C - C - Blitter B - B - B - B - B - B - B - B - B - B So, AFAIK, when there are no other devices competing for memory, CPU could skip a cycle to align perfectly with the cycles inaccessible to Blitter. Then both are running full speed and the nasty bit doesn't even matter (until scanline hits cycles reserved exclusively for FDD and audio). Your display-on diagrams are in agreement with my knowledge so far, because 4bpp display uses only the cycles the Blitter can't use. Quote:

Ah, pity. I guess it's not really worth to try then, as the improvement is questionable - it might even get slower. |

Excellent work @KK/Altair !
What an accomplishment! Clever coding can make all the difference. Only today I was reading about S3TC and how it changed the potential for the S3 graphics card compared to its rivals at the time - made Unreal textures look incredible. Keep up the good work and looking forward to further developments! |

Just right now I've managed to record myself making two first rooms of the demo level, and now I've got about 40 minutes of material to work on (cut/speed up the boring parts, remove breaths, yyy...'s and such). And probably voiceover some parts. I'd really love to start sharing some "making of" videos, but as I've never done such thing _ever_, I'm really nervous and have to learn a lot in the process. But everybody has to start somewhere and hopefully it will be worth it.

People tends to over-criticizes themself (how they sound, or appear), while other people don't even noticed . Breaths are natural, don't over-remove them. Boring parts people can skip on youtube by a single click, and maybe someone will find those parts informative. Don't know what software you're editing in, I can help you if you're using Adobe Premiere, or After Effects (though, cutting clip in After is tedious). Just wanna say... relax... and don't worry too much and put too much effort... it will be good. If you need a logo intro/outro or something, let me know, I can quickly create something. |

Heck, there's even online recording, where you record, and download from the site directly: Maybe this. https://online-voice-recorder.com Davinci resolve, yeah, I've heard its an awesome app... still, you don't need some advanced color correcting options, or tracking features, so in your place, I'd just use some small editing app, without million options that will confuse me, and that I don't need. That Hit Film sound cool, and you're used to it... I'd go for it. Quote:
The idea was just a quick 4-5 sec, something like: KK/Altair making of ... or whatever you want written bum bum bum opening .... and regular video starts Cheers! |

Thanks Marchie for the Resolve tip, looking into it.
KK/Altair, awesome work and appreciate you being so open to all the feedback people have been sending. |

Resolve works great so far. I'm still learning, but I managed to get through first ~4:45 of source material cutting it to 2:50. It's quite hard to explain and work at the same time, so I found myself making many pauses, and you probably don't want to watch me fumbling e.g. with file folders, so such things can be cut out. I think that 20:00 final length would be right for the amount of content I have here.
I'll process a few minutes more and post an unlisted link so you can asses the quality (or lack of). |

From the other side, movie Braveheart had over a 100 hours recorded raw materials that was edited to 2 hours movie. Anyway, the most simple workflow I could think of is this: 1) Basic idea/tutorial that you want to show - show it, and record. (additionally, I'd record "cover shots", like: fingers typing on keyboard, picture on the wall, glint of light on my glasses, when camera capture my face from the other side.. paper that I' am writing something... etc), and voice over. 2) I'd then cut all my shots to what I've imagined. If cut's are not natural, I'll just use "cover shots" as a "transition", between shoots, using only mix transition. 3) Don't use any transition other then cut or mix.. it will look cheap. And that's it! Actually, I recently created tutorial, on my own, and even I know all these stuff, I didn't bothered, editing and recording... I just record it straight... yet.. it was worm welcomed.
