I just remembered what the card seems to be (if I'm not mistaken, it is an ATI Rage 128 Fury). I read about some old gatos things, but it seems that some of the support for those things (parts of the ati.2 driver) was incorporated into upstream (X.org mainline). > > If I happen to have to purchase something, what would be the recommended > > hardware (with Free Software support)? > > I used some old TV cards from Pinnacle (PC TVSAT) and Terratec > (TValue), which have a video-in port which is supported by the v4l2 > drivers. So you should have a look at http://linuxtv.org/v4lwiki for > supported hardware. That is quite nice to know. I didn't know about that already. I am always voting with my pocket, since I only get things that are "Free Hardware", and I'm not that experienced with video cards. > Then you have the choice to capture video in raw format (yuv4mpeg) and > encode it offline to whatever you want. Or to encode it on the fly to > MPEG4 while capturing. Nice. I think that I will package a new trunk version of mplayer with the multithreaded support (the experimental branch). I already packaged newer things than Christian Marillat's packages (and am willing to keep up with some packages that were dropped from sid, like grip). > There is a bunch of tools for capturing from /dev/video: transcode, > mencoder, xdtv, xawtv.... I've been using mencoder for the task, as I'm not familiar with this video 4 linux {1,2} thing. Only now is that I have the (strong) motivation to keep me updated. > On my P4 / 2.8GHz / Lenny, I got best results with xdtv, encoding > directly in high quality mode to MPEG4/AVI. I don't seem to have such a powerful machine (it's a Pentium D 805, with 2.6GHz in each core, and I'm tracking sid). > When capturing in raw format, I loose lots of frames, probably due to > insufficient processor performance or slow hard disk access. Yes, I know, too much bandwidth. > If you want to do some post-processing on the video (de-noising), have > a look at transcode's hqdn3d filter. Yes, the material, coming from VHS, will have a *lot* of noise. For those purposes, I'm used to using two solutions: * yuvdenoise, from mjpegtools; * hqdn3d, with the "hqdn3d=7:6:9" option to mencoder. The part where I am a complete layman is regarding hardware and the v4l{,2} that you just pointed me to. > If you prefer a GUI approach, have a look at avidemux, which provides > the same filters as transcode, and allows also video editing. Even though I prefer the command line approach (I'm an old Unix user), I may, on occasion, use some GUI, but that is only occasionally. > My experience shows that you can do everything in video capturing and > editing with Linux, but it takes a lot of time to find out the best > solution for your specific case. Thank you very much for that part. I didn't know anything about the hardware support. I'm only familiar with videos that are already "grabbed". > If you need a quick solution, maybe you better buy one of those > Pinnacle USB boxes and do the job under windows (grrrrr......) I will see if I can get the ATI card, experiment a little and post back the results. Going to Windows is a very last resort option, as I'm not familiar with the environment.
