As best I can tell, your graphics driver needs to actually support hardware decode to get full frame-rate. It's not clear to me this even exists in any of the X drivers, open source or proprietary. I've gotten a modest performance boost by playing back at 50% or 33% of original footage size. Fewer pixels to copy means a closer X driver is a little less of a bottleneck. The decode is still really slow. Perhaps a format other than mov would be faster. -Brendan ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

The eventual fix was to tweak some audio settings (Believe I was sending too many samples at once). It's a long shot, but thought I'd mention it.

Re: [CinCVS] Editing out bad spots

What is the easiest way to cut these bad spots out using Cinelerra? If it's both the video and the audio, you can simply highlight the portion you want to cut and press delete (or select clear from the edit menu). You might also want to then add a default audio and video transition to reduce the impact of the cut (This may require you cut a little more footage so your transition has material to use). This is quite possibly the easiest thing you could ever do in cinelerra. Default transitions are the second item in both the Audio and the Video menu. Be sure to do both or you'll get your footage out of sync. -- -Brendan ([EMAIL PROTECTED]) ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

The problem on my system was that dvgrab's default buffer size was too small (100). Using dvgrab --buffers 500 took care of it no matter how much else I was doing at the same time.

Re: [CinCVS] titler fade out flicker
Joe Friedrichsen wrote: I've noticed that in some videos I've made as well - the background appears to change the way the title fades in. This is still different. In the sample file (http://www.f-forge.com/?d=EdD1UKgj9LQsCupcxJwR), the flicker is quite obvious - it's not coming from a contrast with the background. Rather, the title slowly and smoothly fades out until the final frame of fading out, at which point that single last frame shows the title at full visibility. I can observe this flicker in cinelerra's compositor during playback and during frame-by-frame advancement. I haven't been following this thread closely, but it does sound like something I experienced and resolved. The problem was that I was using fading keyframes and setting them by hand instead of using the slider. That is to say, I'd press the mouse when the cursor was over the part of the timeline I wanted to fade then drag it downward until my compositor window faded out. Because of Cinelerra 2's quirky feature, for some of the last frames it would actually go past fading out and back into visible again. The resolution for this was to use the slider instead of dragging on the timeline. -Brendan ([EMAIL PROTECTED]) ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

The dual core is a quite beneficial when doing any CPU intensive encoding. Some encoders, such as mpeg2enc, are SMP aware, providing more benefit. Likewise, if you have background rendering enabled, a second core is going to give you enhanced interactive performance. Last I saw, all Pentium D's were 64 bit, so it seems like a better choice over an AMD Sempron.
