Questions that do not deserve a thread

[zakruowrath]

Out of curiosity, is anyone making console CD/DVD drive belts out of the clear synthetic nylon mobilon material that the Famicom Disk System repairs are using?

I take it those don't break apart like the old ones, and would be a better replacement than the stock part on most systems?

From what I've seen even Japanese enthusiasts are replacing their Famicom Disk Drives with the new material belts. I'm thinking it's because even if they do break in the future, it won't melt and become sticky like rubber does over time. I'm just thinking of all the tray loading systems (Sega CD, Xbox, 360, PS2, 3DO, CDI) that could benefit from the synthetic material, just wondering if anyone knew of manufacturers making the belts for CD/DVD Drives.

Gonna bump this so that I get a chance to get answered (original post was last one on the last page)

480p YUV to 480p HDMI for example has more ringing and fuzzier edges than the original.

gotcha

here are the applications I would potentially use with a VP50 then :

-480i dvds HDMI out > VP50 - 480p RGBHV out> RGB monitor (multisync)
-480i dvds HDMI out > VP50 - 720p RGBHV out> HDTV
-1080p blu-rays HDMI out > VP50 - 1080p RGBHV out> RGB monitor (multisync)
-480i ps2 games RGBs(SCART) out > SyncStrike > Extron interface > VP50 - 480p RGBHV out> RGB monitor (multisync)
(for this last one I have the Extron here simply because I don't want to unplug from it every time I switch from native 480p RGsB ps2 games, to 480i RGBs ones, and vice versa.)

Would all those conversions be of excellent quality?

-480i dvds HDMI out > VP50 - 480p RGBHV out> RGB monitor (multisync)

for DVDs you should always upscale as far as possible. It's about finding the monitor's sweetspot and using it.

-480i ps2 games RGBs(SCART) out > SyncStrike > Extron interface > ...

The DVDOs have great analogue low pass filters, so you won't see a difference between RGBs and YUV, hence using component from a PS2 is much easier and you can save yourself all the equipment.

[FinalBaton]

Thanks for your answers *thumbs up*
looks like a dvdo unit will cover a lot of my current needs. This will be incredibly handy.
never considered a dvdo before but damn, it's actually useful for a lot of applications, be it AV or videogames

I'd be super interested in this too.

My Trinitron has strange red lines across the screen. As far as I can tell, they're only visible on a completely black screen.

The model number is KV20FV12

Any clue what it could be?

EDIT:
The lines look like the "Retrace lines" on this page, except the slope is inversed and they're red. (-x)

If you've got an Everdrive you could boot a JP bios for you Sega CD, allowing you to play Japanese games.

Sounds like the best solution to me!

I've read online that this issue may be solved by adjusting some potentiometers on the inside of my CRT. Any advice before I attempt this? I have no knowledge whatsoever on CRT internals.

Also, does anyone know of software that will allow me to convert my lossless SD video into HD video to retain 60fps when uploading to youtube? One that will also allow me to transform the original video into lossy, with a more manageable file size?

My goal is to resize 584x480 video into 876x720.

you can do that with any editing software. Resizing is easily done on VirtualDub. If you record interlaced video you would have to make sure to choose the right deinterlacing options to get a 60fps afterwards. You can also encode into x264vfw using VirtualDub.

To my surprise I've seen videos with 360p and 480p max resolution on YT that had 60fps. No idea how they managed that.

[P1kas]

I record using Amarectv, which has deinterlacing features. I believe the resulting lossless 60fps video is ready to be encoded/upscaled, correct?

Any clue on how YouTube handles videos that aren't exactly 4:3, 3:2 or 16:9? My video footage is 73:60, for example.

[Fudoh]

I think, if you apply deinterlacing in AmarecTV, you'll end up with a 30fps video, not a 60fps one.

you should pad your video with black and upload a full 1280x720p video.

[P1kas]

I think, if you apply deinterlacing in AmarecTV, you'll end up with a 30fps video, not a 60fps one.

Then I should simply grab lossless raw video and process everything in VirtualDub, to make sure I get what I'm aiming for.

Can everything be done in a single step? Deinterlace 480i to gain 60fps, add black borders and resize to 1280x720p without having to encode more than once? Asking to prevent reduction in quality from re-encoding lossy files


Also, when I deinterlace my 480i footage, what resolution is the footage I am left with? 480p60? 240p60?

if you mean by single step without saving the video between processing steps, then yes. In VDub you'll create a list of filters - for example deinterlacing, cropping, resizing, padding and you can save the filter chain for further use.

[Fudoh]

if it's really 480i material, then you'll get 480p60.
If it's really 240p (seen as 480i) you have to add different filters to remove the line offset - technically it's no longer deinterlacing. You would then end up with 240p60 or 480p60 depending on wether you add linedoubling to the filters or not.

[P1kas]

Most of it will be true 480i footage.

That answers my current questions on video processing. I may ask about what kinds of filters are adequate for 240p content later, when I get to my SNES games.

Thank you very much!

[Fudoh]

I may ask about what kinds of filters are adequate for 240p content later, when I get to my SNES games.

depends on how your software captures it. If it's captured as 240p already, then you're set. Just skip the deinterlacing and upscale it right away. If not, then it's a bit hard to explain when you haven't actually seen it. You need a filter chain that creates frames from the video's fields and does a vertical offset correction for every other field.

[FinalBaton]

In VDub you'll create a list of filters - for example deinterlacing, cropping, resizing, padding

Been meaning to ask : can VirtualDub upscale game footage after it's been captured? And is it worth it?
I personnally capture 240p footage(in RGB using an USB3HDCAP) as 720x240, and have AmarecTv linedouble it to 720x480, and upload it to youtube that way.
But Would my video quality be better if I upscaled my 720x480 captured footage to an even higher res using a software? or is software upscaling not to the task in a post production context such as this?

[Fudoh]

Youtube treats 720p and higher considerably better than 480p and lower. Also - but I'm not quite sure about it - I think you only get 60fps treatment on YT with 720p uploads. In other words: yes, you're doing good by upscaling to 720p. VDub gives you plentiful options with different resizing algorithms.

Also - as said earlier - does Amarec give you 480p60 the way you use it ? If not, you're better off capturing without deinterlacing and deinterlace it in software afterwards.

ok cool, will try to upscale my vid in VirtualDub

The YT resolution setting only shows "480p" and not "480p60", so I guess that means it's not 60fps?

If not, you're better off capturing without deinterlacing and deinterlace it in software afterwards.

You mean : no line-doubling in Amarec, but instead doing the line-doubling in VirtualDub?

[Guspaz]

AFAIK, YouTube only supports 60fps on 720p and higher.

[FinalBaton]

Thanks guys. One more ting : I'm tryinf the x264vfw codec in VD and it only lets me choose 4:2:0 color space, is this normal? And will I lose a lot of color depth using this?
Also : will youtube play nice with 1080x720, or do I need to pad it to 1280x720?

[Guspaz]

Just letterbox it to 1280x720.

4:2:0 encodes colour at half resolution, IIRC.

ok, I'll avoid the x264vfw then. thanks!

[Fudoh]

But YT reduces to 4:2:0 anyway, so there's no point in keeping a higher color resolution if you you're eventually uploading it to Youtube.

[FinalBaton]

^^^^^^^
I did not know that. That's a very good point, yes,

[St4rwalker]

My BVM20f1e scrolls down vertically up/down a little bit, maybe 0,5cm, kinda like flickering while in menu..

should i be concerned? no sources connected, though..

[P1kas]

I've followed the advice you've given me Fudoh. Here are my results:

ELA Deinterlacing:

https://www.youtube.com/watch?v=iP1T_lDSa0I

BOB Deinterlacing:

https://www.youtube.com/watch?v=Iw68APm ... e=youtu.be

Past Reference from when I was not upscaling, and simply encoded/deinterlaced with Amarec itself and then resized with separate software:

https://www.youtube.com/watch?v=LRRJ3HTr7kM


As you can see, the new videos look pretty horrible. Any clue what I could do to prevent so much pixelation? You can see what I'm talking about after the 1 minute mark in both ELA and BOB deinterlacing tests. The background around the bottom of the stage looks terrible, as well as the stock icons, etc.

This is what I did to the original video, aside from the deinterlacing:

Lagarith 480i lossless capture
Crop black borders 720x480 -- 638x480
Resize and upscale resulting 638x480 into correct ratio -- 876x720
Letterbox to 16:9 -- 1280x720

x264 compression:
Multipass
3.5kbps


EDIT:

I believe I've found the source of my problem. I thought the encoding speed settings merely affected file size, but it seems that it actually affects the quality you get for the bitrate, so slower encoding = higher quality for the bitrate chosen. I'll retry on very slow instead of ultrafast, see how it works.

EDIT2:

Seem to have another problem.. When I choose to double the frame rate when deinterlacing, half of my video seems to just disappear. It's like Vdub simply doubles the framerate until the new framecount reaches the original framecount, and then just dumps the rest of the frames. When finished with my encoding, only half the video is left. Help?

Also, do you recommend any specific deinterlacing method? Yadif does not seem to be working at all on my video, the preview window shows a completely garbled image. ELA and BOB seem OK.. Is there anything else worth looking at?

EDIT3:

Well, somehow solved my problem with the video disappearing. Not sure what was going on.

Got yadif deinterlacing to work as well, seems it didn't like me cropping the original black borders before applying the deinterlacing, so I simply do it afterwards.

Still would like to hear suggestions if you believe there are nicer deinterlacers available.

[Fudoh]

Yadif the best deinterlacer for 480i material available in VirtualDub. If it fails after cropping you might have to crop one line less (or more) on the top of the video (or just crop after deinterlacing).

Pixelation results from low frame rate or other settings. I never used x264vfw from VDub, but frameserved losless from VD instead into the x264 command line util.

[NightSprinter]

Would out-of-spec sync voltages affect viewing RGB over a monitor or with a capture card? Just curious, as I measured my model 2 Saturn's csync output at 2.78v (as opposed to my SNES which outputs at a flat 2.5), and every VGA card for my Win98/DOS machines all output hsync at under 4.4v (5v for vsync, and adding an interface just makes my capture card unable to produce an image).
