  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Redcode Quicktime strangeness

Hi I have a Mac Pro 8 core, 2gb ram, nvidia 8800.

I've been testing out the new Quicktime "Half Standard" decoding mode and it doesn't seem to be any faster than "Half High".

I'm playing the _H quicktime reference of a 4k .r3d file and Quicktime reports a playback rate of 13fps no matter which decode setting I use. I also looked at the CPU and disk usage they are the same on both decoders. the CPU usage sits at around 30% and the disk usage is 30MB/s.

I'm not sure why it's only getting 13fps when playing back the 1k reference I get full 25fps and it has pretty much the same CPU usage. I would have though the player would use the other 70% of CPU and playback at 25fps.

Anyone have any idea why:
1) the 2k playback isn't running at 25fps even though it has loads of unused processor power.
2) the new "half high" doesn't appear to use less cpu.

Thanks

-Andrew
