playing lossless format in premiere cs4

[Danny Winn]

Two things,

1. Set your playback quality to “Draft” not “Best”, it will still look awesome since it’s HD.

2. When I use Lossless HD footage it always plays better if I do anything to the footage that requires me to render it, I usually Right click over the clip then select “Field Options” then “anti Flicker” then render all. Or any other effect or CC that makes you render the footage.

Let me know if this helps, good luck.

You can *never* playback 1440×1080 QuickTime Animation clips from *one* (1) Seagate Barracuda 7200.12 1TB. You *cannot* playback lossless avi files either. You must have a RAID if you want to be able to playback those files.

So yes, what you experience with those files are normal for your system.

Try the CineForm codec. They can and will playback from a single hard drive and will give you the quality you are looking for. https://www.cineform.com

I must disagree with Roger over the capability of drives to play lossless footage. I use my second PC (Q6700 4Gb RAM WinXP SD Decklink) to lay back uncompressed program mixdowns all the time from a single Seagate SATA 7200 Barracuda. Granted, the files tend to be less than 20 mins – but I don’t get any problems whatsoever.

Note the emphasis here on mixdown. Where one might get problems is through Premiere in a rendered (non-mixdown) timeline. Here you are asking a lot from both cpu and memory to switch instantly between rendered shots.

It may sound old fashioned but I don’t hold with all this fancy stuff from Adobe about being able to open everything ‘live’ all the time. I finish a program, check it, check it again and then mix it down. If I need to amend it I export it again – it only takes a few minutes.

This works for me but I do recognise that this might not be to everyone’s taste.

I interpret your spec that you have a Decklink SD.

Yes, there is no problem playing back uncompressed SD from a modern drive, but Leo want to playback HD and thats another beast. A single HDD cannot sustain the data rate required for uncompressed HD footage. Compare uncompressed SD with HD and see it for yourself! 🙂

Good point Roger. But I had calculated that he had HDV files because of the aspect ratio and hence my comment. I agree that one would be waiting for Godot before a pukka HD file would play on a single 7200 drive.

Yes…he said he bought the system to play back HDV files, but is frustrated that he can’t play animation QT and uncompressed HD files…

HDV has the bitrate of DV (25 Mbps)…uncompressed can run as high as 1.2 Gbps…

Obviously we have some confusion about the relative bitrates between these filetypes. HDV can run from one 7200 rpm drive easily enough…but even a basic RAID will have a challenge with uncompressed HD. A fairly massive 7 or 8 drive array will typically run about two streams of uncompressed HD…two vastly different filetypes.

Thank you for all your answers! I just wanted to know if there was something wrong with my pc configuration.

Thank you for caring!
