ProRes Proxy playback performance

I have the same laptop, and I captured 40 min of footage from HDCAM to ProRes Proxy via my Matrox MXO2 into my laptop on a G-Drive mini via FW800. Not one dropped frame. And editing performance has been normal.
What drive are you using? Has to be good, knowing you. But just curious.

Hmmm...should work off the internal. DV does. I'll bet the dimensions are the reason it is skipping. Lower data rate, but large dimensions. I'll have to try to play some Proxys off my drive soon...

OK Tom, I FINALLY copied over the ProRes Proxy clips to my system drive, and played them. I am getting no dropped frames, and overall performance is good. Been on a loop now for an hour while I went to lunch.
And the quality doesn't drop significantly when I play as opposed to when I am paused. There is no difference really.

Re: Unable to output to tape via firewire. January 09, 2010 09:20PM |
You are trying to Print HDV out to DVCPRO HD via firewire. IT won't work. The computer is outputting an HDV signal, but the DVCPRO HD deck doesn't recognize that signal. You need to export a self contained QT movie, convert that to DVCPRO HD 720p60, drop that into a 720p60 DVCPRO HD timeline, and then you can print to video via firewire.

OOp, sorry. I have it stuck in my head that DVCPRO HD on tape is 720p. Thanks Andy.

Correct me if I'm wrong, but doesn't DVCPro HD on tape have both 720 and 1080 options? I've worked with both Varicam and tapeless HVX-200 footage, and all are 720 -- but I remember 1080 as being an option at the shooting stage.

>the default DVCProHD 1080i is 1990x1080.
No it's not. DvcproHD 1080i is 1280x1080 in NTSC countries, and 1440x1080 in PAL countries.
>but every time there's a pan or fast camera movement, the video is jerky.
HDV isn't very good with motion. And if you rendered your footage out as HDV, you're taking double hits on mpeg compression. You could try rendering straight to dvcproHD.

When it comes to Varicam and TAPE, I am used to 720. I know 1080 is possible, but I have never used it, that is why 720p is stuck in my head.

Is the original footage 23.98?

To be absolutely pedantic...
DVCproHD Pixel Resolutions:
DVCproHD 1080i50 is 1440x1080 - Displayed at 1920x1080
DVCproHD 1080i60 (actually 59.94i) is 1280x1080 - Displayed at 1920x1080
DVCproHD 720p for all frame rates (including VariCam) is 960x720 - Displayed at 1280x720
PAL and NTSC are Standard Definition only. Try not to mix PAL and NTSC up with HD in the same noun eg: "PAL HD" - it's a contradiction in terms!
(Not that G was saying this but just for clarification!)

THey are APPLE INTERMEDIATE files...from HDV. They are NOT DVCPRO HD files, and that is the only way you can print to video to the 1200 deck via firewire. So you need to convert them to DVCPRO HD, then output. Or get a capture card and output that way, SDI to the deck. Then it doesn't really matter what format they are in the timeline.
