x264vfw and aac question
Hi Everybody,
I know that x264vfw is great in video conversions but I was wondering a way to record my camera with him. I already use TvideoGrabber from datastead.com http://www.datastead.com/products/tv.../download.html for WMV recording, recently they update the component to record in mp4 too. Following their own tutorial http://www.datastead.com/tvideograbb...mples.html#MP4 I can record my camera and audio but about 00:01:25 of recording, my camera starts to "hiccup". One thing I note is that without capturing audio, the video file pass 00:01:25 of recording without problem and my camera doesn't "hiccup". I believe there is some configuration in x264vfw i don't know, so I would like to know about you guys. 1) Anyone can record with x264vfw? Which is the basic configs? 2) Anybody have any idea why i'm having this problem? PS: i'm using x264vfw last version, windows XP, Intel processor I5 |

I would avoid any transcoding while capturing. I would suggest to capture in native source format (only this should be called capturing, IMHO, the goal should be to get the source to HDD frame by frame, not risking any drops, no conversions attempted, we have time to do this later on) or if one can afford the storage space, as uncompressed. Any MPEG-4 AVC takes so much processing power to encode, especially for HD sources that encoding really should be the final step before delivery. If one attempts to encode HD resolutions to H.264 in realtime, so online, the final quality will have to suffer compared to what would have been available if encoded with slower settings and offline. Here x264 blu-ray HD encodes take some 0,7..2.5fps per pass, CPU and commandline depending. No heavy Avisynth filtering included (!)

I understand.. recently i find out a new way to encoding.. (at least work great in GraphStudio)
I am now trying to use Monogram X264, Monogram AAC and Monogram Mp4 Muxer to do mp4 files.. So far it works great in GraphStudio.. My problem is: TVideoGrabber list as video and audio compressors filters that are registered in VideoCompressors and AudioCompressors category, but MONOGRAM's filters are registered in DirectShow Filters category.. So the question is: How can I register / move the filters to VideoCompressors / AudioCompressors list? Believing this way would fix my problem with TVideoGrabber |

I repeat Emulgator's recommendation to capture (nearly) losslessly and then re-encode later to H.264 & AAC. x264(vfw) may be suitable for the lossless capture task with fast settings. UtVideo is also worth trying (discussed in English here). Last edited by nm; 1st September 2011 at 13:05. |
