Re: [CinCVS] dv grabbing (off topic)

Is it something wrong with my system? Are you using Cinelerra or dvgrab to get the data? I usually use dvgrab myself, and used to see this all the time. Even if I didn't do anything else. 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. If you're capturing with cinelerra, perhaps there is a similar solution. -Brendan ([EMAIL PROTECTED]) ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

Re: [CinCVS] Mpeg2 encoding
Graham Evans wrote: I seem to remember that some really logical choices like Format Preset: DVD led to render errors. For me the options given above worked and I generally only fiddle with the Bitrate. One needs to use DVD-NAV (Type 8) rather than the DVD (Type 9) variant. Type 8 is the mpeg format that DVDs actually use (For instance, when using mplex, one uses mplex -f 8 to combine audio and video for a DVD compatible mpeg). If I post a patch for this, will somebody with svn write access check it in? -Brendan ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
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
Re: [CinCVS] Single (Powerful CPU with Hyperthreading) vs. SMP vs. Multiple Cinelerra Render Nodes
Kevin Brosius wrote: Have you tried cinelerra on this system? Your comments seem odd, as on my dual systems, cinelerra will use both cpus (or cpu pipelines on HT machines) during rendering. For actual rendering you're likely to see a performance hit if you let the renderer use both cpus of a hyper-threaded system. Best to check the force-single-processor flag in the settings and use the second execution unit for non-number-crunching operations (Surely your underlying OS has something else it'd like to do)! -Brendan ([EMAIL PROTECTED]) ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
Re: [CinCVS] Pentium D 2.6 GHz or AMD Semprom 3.0 GHz
Pierre Marc Dumuid wrote: Anyone have a suggestion either way? I initially thought AMD Sempron cause as I was personally curious to see how a 64 bit machine performs, but now I am actually thinking that the dual processor may be more useful? 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. In either case budget for plenty of RAM since a fast CPU won't matter if you're swapping heavily. -Brendan ([EMAIL PROTECTED]) ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

I reduced the number of devices by not taking into account the devices in 666 mode, or devices whose group is one of the groups which the normal user belongs to. I get 1332 devices nodes only. Any idea? The quick and dirty way is to run cinelerra under strace like so: strace -o /tmp/strace.output cinelerra You can then look at the open()'s issued by cinelerra. It'll show you what path was attempted and whether or not it succeeded. For a better idea of what might be causing a crash, you could run cinelerra under a debugger such as gdb. -Brendan ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

Hmmm. Maybe. I'm not sure if anything else is necessary, but I've run yum-arch and createrepo and uploaded the resulting headers.

Re: [CinCVS] Is RawDV export still broken ?
Since it seems nobody is really benefiting by having the '-q 0' setting
for mpeg video output, I propose the following patch. If there's other
braindead command line arguements in there by default, we can tweak them
as well.
