Tutorial for capture'n'encode video from real C64
Hello!
Is there anywhere any tutorial step by step to explain how to:
1) record a video with music of course using PC TV card and C64 connected via s-video cable (which program is the best for it, eventually configurations?)
2) encode the video with deinterlace (or if I'm wrong, just help) - which program, how to use step by step.
Tutorial like this would help more people with recording stuff from real C64.
I've tried to record the video using Winfast PVR and DScaler. First one has no smooth scrolling (maybe deinterlace encoding needed or I dunno?) and second one strangely has bad video quality output.
If anyone could support me with any quideline how to properly record and encode videos from C64 it would be appreciated. Maybe is there any guideline on web?
Thanx in advance!

That's another thing. MPEG2 is more CPU-friendly, you don't need a monster-PC to watch it. Also, with good encoder and finetuned settings you can get awesome quality at VBR 5500kbit/s. But of course, there are many choices :) |

You don't have to go higher than 1500Kb/s with x264 or h264. (the above flick I've posted is 1300Kb/s)
The ability to decode h264/x264 with GPU has been existed on ATI/Nvidia/Intel-cards for a few years now, so no monster CPU is needed. You need to use Level 3.1 (standard definition) or Level 4.1 (high definition ie 720p/1080p) for 'hardware decoding' compliancy. This is done by telling the encoder to use a certain maximum number of reference frames, this is done by calculating 6750*1024/1.5/(X*Y)1 for SD where X=width-mod16 and Y=width-mod16, for example 6750*1024/1.5/(720*576)=11. 6750 is the MaxDPB for L3.1 , 12288 is the MaxDPM for L4.1.
MeGUI already has a number of 'DXVA'-profiles for x264 which have proper settings for these GPU-decoding compliant techniques, in case you don't know what you have to do.

wackee, please describe what hardware you're using to do A/D outside computer. |

I am using a camcorder with a/d interface, also by Sony, DCR-HC90. Back in 2005 when it was released it was really top of the line considering features - I wish I had at least half of those in my new Full-HD one (interval recording for example).
Anyway, it really does a good job for converting from analog to digital, and accepts s-video signal, not only composite. I have it hooked via firewire so I grab the captures directly on the go, without using the tape, with the data rate of 25Mbit/s. Right now this is the only job this camera is doing anymore - only C64 captures :)
Of course, there is also additional postprocessing after the capture. |
