Video converter of small to big



Frage von vs:
Januar 2011

As the question "How do I convert s.besten yes again and comes back, here is a view of what it s.Wandlern (cards, boxes, etc.) are. I think that whoever has read into the matter a bit, may well decide it, what solution he personally preferred.

Classic TV cards:
- Type: PCI
- Image quality: Most useful
- Sound quality: Depending on the sound card
- Finishing possible: Unrestricted (uncompressed video)
- Risk Audio / Video asynchronously: High, because sound from sound card. Virtualdub can compensate for the now very good, genuine Locked Audio of devices with unique audio input is to be preferred
- Driver support: It depends on Manufacturer or third-Drivers. The support of current operating systems is synonymous with old cards / chips very well, with the latest third-party drivers (the best example for the BTWinCap Bt848/878).
- Software support: WDM and / or VfW-compatible drivers. Runs with any recording software, so no preference whether editing program, VirtualDub or other software.
- Another potential problem: Low to nothing
- Other benefits: Analog TV tuner for cable with s.Bord. Caution: The large number of DVB cards (DVB-T, DVB-C and satellite DVB-S) have a rule (there are hybrid cards as exceptions), no analog inputs and are therefore not suitable, but there are exceptions with analog input.
- Space requirements: 20MB / s for YUV or 30MB / s for RGB (without benefits)
- Price: from 20 ¬
- Typical: Hauppauge WinTV, Pinnacle PCTV

PVR TV cards and USB PVR devices (real-time recording in MPEG2 with Hardware Compression):
- Type: PCI card for USB 2.0 for USB devices
- Image quality: Most useful, however, come here already MPEG artifacts (image noise of the beneficiaries) pure during the recording. Quality comparable with DVD recorders. Offline encoding (in one encoding software for the recording), particularly in 2-pass mode is much better.
- Sound quality: Good
- Finishing available: Restricted (filtering would decompress and re-compress and therefore require re-amplifying the artifacts, cutting programs are slower, require cuts Neurendern effect of processed bodies used for that smart rendering technology can lead to non-standard GOP)
- Risk Audio / Video asynchronously: None, as part of your own audio
- Driver support: It depends on Manufacturer or third-Drivers. The support is still good, but just in alternative operating systems like Linux, on older products synonymous Vista, it looks tight.
- Software support: one is forced to be nailed to the Manufacturer Software
- Another potential problem: None known
- Other benefits: The only solution that delivers directly MPEG2, which can be taken without further step in the DVD authoring program. Convert lengthy deleted.
- Space requirements: under 1MB / s (~ 8Mbit or less - on DVD are a target medium authorized up to 9.8Mbit to the general stream, ie audio + video + radical such as subtitles, but then hardly what fits on the disc)
- Price: from 100 ¬
- Typical: Hauppauge WinTV PVR

USB devices can deliver uncompressed video:
- Connection: USB 2.0 (important, USB 1.1 is too slow)
- Image quality: unpredictability of very poor to very good
- Sound quality: As above
- Finishing possible: Unrestricted (uncompressed video)
Risk asynchronously Audio / Video:
- Low cost devices without the audio portion: High, because sound from sound card with equipment without audio portion. Virtualdub can compensate for the now very good, genuine Locked Audio of devices with unique audio input is to be preferred
- In good consumer products as well as the professional league: for devices with little to no audio portion
- Driver support: It depends on Manufacturer or third-Drivers. The support is often good, but there are just loose candidates in the no-name segment. to find non-drivers is often unmögich because you do not know what hardware is installed in it. Moreover, at no-name products, the drivers often very unstable.
- Software support: Most WDM



Antwort von Paul*Berlin:

Many, many thanks for the effort!

One question I have as yet to the DVD recorder: You write a post is barely possible - I'm planning to dump a live cut-Project on a DVD recorder that can cost up to 300 ¬, low-cut then the pauses and then back on DVD. Does it then not at all like me, I was thinking? For the use of an A / V card oä lacks the powerful calculator, which all falls out of the frame's price ... What is with the DVD recorder in it?
