Via C3 Nehemiah 1GhZ - TV Recorder? Will a via C3 Nehemiah 1GhZ cpu able to record TV-shows in real time? I don't think it's powerfull enough. But I don't have an epia board so I can't really judge the power of the Nehmiah :D If I can record shows real time, in what kind of format can I encode? Mpeg2,divx,xvid,wma,...? I hope you guys can help me :D Thanks in Advance :hello: |
There are TV-cards that can encode in realtime to Mpeg2. Compro has a fairy nicely piced linup capable of this. The CPU itself won't be able to do that however. |
It's kinda expesive, epia board+mpeg2 card I think a microATX AMD board +CPU+AIW card wil be a better option for almost the same price :) |
You'll need about ~ 1Ghz AMD Athlon / P3 power to record in real time high quality divx + high quality sound. Recording in mpeg2 and 2channel mp3 should be duable with a via C3 Nehemiah 1Ghz. I'll try it out for you. |
I just tested a whole bunch of codecs, and two seem to work great for the nehemiah: Xvid, 400:300 resolution max, 96kbps lame mp3 (about 100kb/sec) Uncompressed YV12, any resolution, 96kbps lame mp3 (about 4mb/sec) A pitty i didn't find a good codec in between these two extremes (mpeg2 codec was too choppy). |
The xvid, 400:30 res,96 lame mp3 Is that good quality? Can you mention the during of the recording and the size of the file you encoded? What do I need beside a epia board? Just any Tv-card? What kinda card do you have? And thanks for the help so far:super: |
If you're using linux i'd recommend a brooktree bt484 chipset based card, because they are widely used and therefore well supported. If you're using windows, i wouldn't know which one to recommend, but i know i had difficulties finding a good, free videorecorder app for windows. 1 minute in xvid is ~ 6.5mb. CPU load is +- 90% so you got little headroom left for tweaking. Quality is mediocre + no interlacing + no 'smearing' / bugs + very fluent - not sharp enough (*) - 400:300 is good for personal use (*), eg recording the news or your favourite sitcom, but i wouldn't watch a movie in this quality. I'll try to tune it a bit further and show you a screenie. (*) 640:400 eliminates this, making the quality of the video excellent, but it's too choppy most of the times (maybe 15-20fps instead of 25), If i could just tweak some options to get it fluently, this epia rig would be an excellent tv recorder. :) |
And the epia isn' able to do 640:400? What do you mean with choppy? Shocking, not really fluent? If it is. I thought, the fps the more fluent the crossovers will be :) |
The epia isn't able to do out-of-the-box 640:480 xvid encoding on the fly. The xvid encoder has many options though, and I've gotten a great improvement tweaking so far. I'll report back if i can find a way to record 640:480 flawlessly. |
build a silently cooled AXP rig, Mobile XP @ 1200Mhz or so (with a vcore of 1.45 or lower), very big heatsink (MCX462-V) and a temp controlled, silent 90mm.. my 2 cents.. then you can record at 640x480 without probs. |
I know that, but I want a as small as possible recorder :D, a very big hs will be no option :), maybe I can cool the mobile XP with an modified artic silver vga cooler (don't know it'll be sufficient)? You'll probably say, buy one from carrefour, but I won't be fun and doesn't have a lot of possibilities in comparison with a pc:p. Now I've to look for a second hand R8500AIW :) How's your xp doing :D |
