Experimenting with the "Quality" setting.
Experimenting with the "Quality" setting.
This has probably been done before, but I cannot find definitive results. I could spend lots of time doing research myself, but the wife and kids think I am crazy already!. Question is, does, increasing the "quality" setting,which is nominally set at 80%, produce bigger MPEG files whilst capturing on the fly. I know it does improve the quality but problems with Transcoder Buffers eventually surface with my P4 2.8GHz (nothing else is running). Thanks
moving the speed/quality slider shouldn't change your resulting file size. To change the resulting filesize you would modify the BITRATE.
However, I suspect you start getting the "transcode buffer..." message because the quality slider does change the way the captured video is encoded. Moving it towards Quality will change the "motion search" parameters during the encode, this would make it take a slightly longer time to encode, and over "captured duration", the buffer might fill up faster. If you move it to the "Speed" side, then the motion search doesn't look as long while encoding, and so the buffer doesn't fill up as fast.
