Hi Kees,

This is just so cool, I'm almost speechless!

I notice the videos are slightly jerky at times. Is this just an artefact of the video, or is the rendering running out of cycles and skipping frames? Is it any better at 2MHz?

Yes I know ...... I'm using CAMstudio on a not so superfast laptop.
I record at 50Hz because CAMstudio cannot record at 60Hz.

The framerate x capture time must be 1000 and I can only input integers ....

It would be nice to have a capture option in Atomulator like Wouter Ras his emulator had .......

I haven't build in a decent timer yet to time the frames at 50 Hz but I think this is too optimistic for 1 mHz.
The engine and the sprite routines also have to be optimized but first I want everything working.

Maybe the Z80 copro is an option .......

This video is recorded at 100Hz: https://www.youtube.com/watch?v=ZJSrCT-SfYQ

Stats for Nerds in YouTube says: 430x360@15.

Earlier videos were 430x360@10 I think.

Not sure what to make of that....

Are you on Windows 7 or Windows 10?

oss003 · Post by **oss003** » Mon Apr 16, 2018 9:04 pm

Windows 7.

In Camsstudio I selected region so it records the Atomulator window.

IIRC there was an Electron emulator with record option. Also David Boddie did some testing.

My fork of Elkulator has a video recording function. I didn't get round to making Atomulator do the same.

Do you have a link to your fork? I couldn't find it in github.

davidb · Post by **davidb** » Mon Apr 16, 2018 9:52 pm

It's on Bitbucket but could easily be imported into a repository on GitHub.

Loving all the work going on with this. Could open up some much needed interest in the Acorn platforms.

Dave,

did you have a look at David's sources at Bitbucket for video capture?
Is it possible to do this in Atomulator?

Sorry Kees, not really had a chance to look at this yet.

Dave, I've sent you a pull request for your Atomulator repository on GitHub.

I also recorded a video and uploaded it to YouTube but it seems that 512 x 384 is a video size that causes problems as, even after a few minutes, it's still not been processed.

Great, I'll merge that this morning.

davidb wrote: I also recorded a video and uploaded it to YouTube but it seems that 512 x 384 is a video size that causes problems as, even after a few minutes, it's still not been processed.

Could that be fixed in the python code, by scaling/padding?

Seems the standard resolutions supported by YouTube are:
- 2160p: 3840x2160
- 1440p: 2560x1440
- 1080p: 1920x1080
- 720p: 1280x720
- 480p: 854x480
- 360p: 640x360
- 240p: 426x240

None of these are a great match to the Atom vertical resolution - 192 (or a multiple of 192).

Yes, I'll pad it, I think.

- 480p: 854x480
- 360p: 640x360
- 240p: 426x240

I think the 480p option with padding is the easiest to begin with. I may well make it configurable.

davidb · Post by **davidb** » Tue May 08, 2018 11:51 am

I was including invalid audio data in the video which YouTube didn't like. Since the upload process can pad the videos itself, I reverted the default video size to 512 x 384, though you can specify a different size if you like.

My first successful upload is now online.

The video is 60 frames per second. I assumed that the Atom's video output is this refresh rate - is that correct?

Sound needs to be looked at because it is handled in a different place to video in Atomulator.

Thanks David, looks great .....

Yes the refresh rate is 60Hz.

I've merged David's commits into master now.

Before releasing this, we need to add the start video/stop video to the windows GUI. I'm looking at that now.

Nice job Dave and David but how do I upload the .vid file to Youtube?
I'm getting an error: unknown format.

Do I have to convert it to another format?

Greetings
Kees

davidb · Post by **davidb** » Tue May 08, 2018 8:21 pm

Sorry Kees, it's not quite as simple to use as I'd like.

You have to use the tools/frames2avi.py Python script to create an AVI file:

Code: Select all

tools/frames2avi.py video.VID video.avi

That tends to be quite large and probably not ready for YouTube either, but you can at least use a normal video conversion package to get an MP4 or WebM file for upload. The script prints out suggests for command line tools to use but they're probably mostly useful for Linux users.

Ok guys,

another update, I fixed some more bugs and added sound.

- Unzip FOGGY into the MMC directory of Atomulator
- Start Atomulator
- Type *FOGGY
- Let the play begin ........

Keys:

Code: Select all

- Z   = Left
- X   = Right
- ;   = Up
- .   = Down
- SPC = Jump
- P   = Inventory (works on the special blocks)

You need a 32KB Atom with 8KB video RAM.

Greetings
Kees

I did some testing with SID music and addded SID music to the AGD game Moritz.
The game didn't use all 32KB RAM and there was enough free space to add SID music during playing.

The same game is compiled for a CPC:
