MPG 4 real time capture

[CORRY20]

I have been using neodvd MPG2 and then using virtual divx to compress it so I can put it on a dvd.I want to real time record into MPG4.When I use neo dvd and after I finish recording the video looks like it is in fastforward and doesn't sink with the audio then It slows down again and then speeds up.I am not hitting the fastforward button on my vcr at all.I looked at Mcfunsoft video soultions and they have a nice video encoder andybody know of any others?

To record real time in Mpeg4 you just need VirtualDub and the Microsoft codecs listed into the relevant section of this site.
Or you can also use Xvid, a very good evolution of Mpeg4.

Capping is very CPU intensive. If you have a slow CPU you will have problems with Xvid or MPEG capture. Since you haven't filled out your computer information, no one has any idea what you have.

Do you have a Divx player that you are using to display the finished product? If so, why cap in MPEG? Just do a Xvid or Divx cap as uxbridge suggests.

Hi,
I've had good results using the 3ivx Codec and it's Filter Suite (www.3ivx.com), To make it fully MPEG-4 requires an extra step since VirtualDub and other .avi capture utilities won't write to a mp4 container. This means you wil have to convert your audio to AAC and mux it into an mp4 container. There are guides at 3ivx.com explaining how to do this with a free program called GraphEdit. Doing it this way is still much faster than re-encoding the entire file from MPEG-2 and depending on the settings you use with the 3ivx codec yields great quality. As the previous poster mentioned you are going to need at least a P4 or equivalent processor for realtime capture of MPEG-4 though.

I use VirtualVCR to capture real-time using XVid/Mp3 and no frame dropped.

These are the configuration in VirtualVcr:

Video XVid:
Resolution: 720x480
Frames p/ second: 29.970
BitRate: 1500kbps

Audio MP3:
BitRate: 192kbps
Freq.: 48000kHz

If you want good compression and quality, MPG 4 real time capture in full frame is very processor intensive and can lead to dropping frames. If you do drop frames, try using divx 6.1 in the fastest mode. This may keep up. It is in an AVI container not an MP4 container.

[roglopes]

I confirm what user "geowharton" said.

In many cases when I was using XVid to capture in 720x480 - 1500kbps the video had dropped frames, then I change to Divx 6.1 with the same resolution and bitrate and no more dropped frames.

I use Hauppauge Wing with my PVR-150 to capture in DivX in almost real time. It begins the encoding one minute after the recording begins and finishes about one minute after the recording is done. That is about as close to real time as you can get and you won't get dropped frames since the hardware encoder needs very little resources to capture.

So are you saying that you are captureing to an MP4 file directly?? If not then the Hauppage WING application might be the best solution yet, except that I do not have a PVR150.

No it not directly in to MPEG-4 it not a Hardware Trasoncoder man a lot us being want that one for past few years.

what it really is, is a real time software trasoncoding the MPEG-2 file in MPEG-4 "PSP and iPod recording option" or DivX and it now support Creative Lab Zen Player.

Is there anyway to use WINGS with my ADS Instant TV deluxe PCI card (which has hardware MPEG2 encoding) or am I required to use a Hauppauge board.

[SHS]

Sorry it required a Hauppauge board

can you link a 1 minute sample clip of something with lots of action? i have seen some realtime divx videos created by convertx that didn't look so hot.

I am at work right now so I cannot attach an example clip. This is not realtime capture, it is more like realtime encoding. I capture 12 Mbps and I setup a DivX profile in Wing. Wing is incorporated into the WinTV Scheduler so you tell it what profile to use when you schedule your recording. The advantage here is you do not have to wait for the capture to complete because the encoding is done on the file while it is recording. I know of no other programs that can do this. You can also use Wing on any mpeg-2 files. Not bad for $25 if you already own a WinTV-PVR 150/250/350/500.

What I used to do was open the file with VirtualDubMod, cut the commercials out, save the trim points, save the .wav file, convert the trim points using vcf2avs and copy them into an AviSynth script and encode the video and audio in VirtualDub. Now I just open my DivX file in VirtualDub and cut the commercials and save using Direct Stream Copy for video/audio which only takes a few minutes. The difference in quality is little to none and far superior to capturing directly to DivX be it hardware (I have 3 WISGO7007SB devices) or software (Compro Videomate Gold+).

Thanks to SHS for the Wing update, it solved intermittent sync issues I was having. I don't see any updates on the Hauppauge website.

Strongbad when I was doing Stargate SG-1 and BFG there come out pettey dran good but I didn't keep any.
Your welcome Suds and I alway get them first Suds.
