  • 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 :)

Even with me setting the option to 1.4 medium the process going from the r3d files to a 1024x512 proxy quicktime is agonizingly slow. i can play the files back at near realtime (24fps) on the mbpro i have here but i can't decode them in RT. I don't care as much about the quality, since I will be onlining in scratch, but i want to get the offline qt's rendering as fast as possible.

anyone have any clues or help to make this happen?

thanks

I have same problem with MacBook Pro , but not with all , only 1 can not play real time , it looks like HDD problem . I have no time to format drive , but i thing that it will help , and also try to update system to Leopard if it is Tiger . What about Memory , 1Gb or 2GB

I have leopard 10.5.3
macbook pro at 2.4ghz with 2gb ram. the system is about 2 months old so it's pretty solid at this point.

i can play quite a few clips realtime no problem at all. did some on set grading for the director and dp.

i assumed that when i set the project drop down to 1/4 medium that the conversion would only debayer that way versus a full res debayer and then a res down. well, it looks like a full res debayer at any rate based on the update/render speed.

Yeah, on a Mac skip RedCine and use compressor to convert the proxy files to ProRes at whatever resolution you want to edit at. That's way faster and looks good if the original footage is really good.

i have used compressor for all the files that were not shot 16x9.
unfortunately i have an entire day's worth of footage to output that was shot at 16x9 so the quicktimes crash compressor. :/
 
What you want, is to change the "Process" dropdown, as well as/instead of the 'Show" dropdown in Redcine. By changing 'Show' to Medium, it will change what the display is showing, and "Process" will change what the output is debayering from. The best speed increase for offline is to lower both.
 
Also, remember that different codec's take different amounts of time to encode. So you may like to change the codec to see if that has a dramatic affect on processing times. Making sure that your NLE supports given codec of course (you may not have many options, all these things are just good to isolate to understand what's happening behind the curtain).

Don't know what you are editing with, but the fastest output I have found is SD saved with an Avid DV codec with an 8 proc machine. It is about realtime. Here is a link to a post with a video I made a while ago showing how: RedCine almost realtime to SD

I also just did a test on a RedBoxx running Red Cine, and it created 2 hours of footage in 1 hour 10 min. Much faster then realtime. The strange thing is that Red Cine is much faster than Scratch for this kind of encoding.
 
I'm getting faster than realtime to 1024x576 DV-PAL QT in Redcine on a 8-core Xeon machine. Maybe it's the 8 processor cores making the difference though. Still, I have a colleague who has done SD proxies on his MBPro with just under realtime results, I'm not 100% sure what his settings were, and I could be wrong but I thought it was doable.
 
i know where the process drop down is in scratch, but i only see one drop down in redcine. that is the one just to the left of the playbar.

sorry for being completely n00b on this one.

where is the process drop down?
 
is it the option for 'draft' ?
if so, then i found it but it's still slower than just playback. that's prolly due to the prores422 conversion is my guess. much better though :)
is that what you wanted to tell me lucas?
 
Hi throb,

I don't have Redcine open in front of me, but the process drop down is in the output section.

Edit: Whoops, didn't read the second page before I posted. Hopefully Lucas has given you a hand..
 
Hi Guys,

One other quick suggestion just in case it was overlooked: Make sure you choose the output resolution in the Project Tab of the Player Window, then use the SHOT tab to frame your shot within the delivery resolution you choose in the project tab, make sure the resolution set in the Project Tab matches that of the Output Tab. If you leave your shot at 4K in the Project Tab and just set the output resolution in the Output tab you will essentially get a full debayer process regardless of the debayer process setting in the output tab(draft, standard or full), this will definitely affect your render times.
