dear sirs,
i am using Combustion 4 installed on a pc whih the following configuration
Intel Dual Core 830
Gigabyte Chipset 955X Royal DNA
Ram : 2 GB 533Hrz
Nvidia Quadro 3400 256MB
Hard-Disk Maxtor 80 GB 7200 PRM
the problem that i cant get a realtime preview playback while working on Compositing .
what shall i do in order to make it work …
Combustion is not a realtime application. EVERYTHING must be cached in order to play in realtime.

Hi use the Render to RAM feature. With that Realtime playback is possible even on an older computer. To speed up the overall workflow I would suggest you to invest in SATA RPM 10.000 or SCSI Raid drives. Just for info all desktop compositing applications must cache before realtime playback.
Sometimes deoending on your comsize and footage playback is near realtime when OpenGL is turned on.
Hope that helps.
realtime playback without caching or render to disk, does not possible in Combustion despite the speed of a machine. We did a test with combusion fusion and after effects on a machine that had the disk through put required to playback real time and whilst the others could do it and combution in theory could read the files fast enough… it wouldnt play back realtime. Maybe its a code limitation ?!? Maybe its deliberate !
Hey Aneks,
I would be interested in the test you did. What footage source did you use? How many frames? What file types? What were the system specs etc. What were the results specifically.
Regards

Working on a PAL Edit project, Combustion can read in realtime Quicktime videos using Motion JPEG codec. The same when you just open the files in a simple composition. The machine is not fast though, just 1 P4 2.4 CPU using common IDE hard drive.
Yeah I’ve just decided that combustion is unable to operate in real time.
I’m running a Dual Core 3.2 Ghz system with 4 Gigs of ram on XP 64 with a 10,000 RPM SCSI drive.
It still will have to cache just to play an uncompressed 720x480 avi, no effects.
