edit with uncompressed file?
Hi, I’ve exported a 1080 QuickTime fille with the “none” codec settings from ppro cc with the plan of dropping it into a new sequence and applying more edits. It’s lagging quite a bit in the timeline on playback. Is this too big of a file for premiere? If I plan to add more edits to an exported file should I go with something other than the settings I’ve chosen. My choice in QuickTime files was made solely in attempt at avoiding any quality loss. Is this over kill? What’s the best export for someone who plans to drop into premiere pro again for more edits with out loosing quality? The project is going to be displayed on the big screen not the web which is why I’m so careful about this. Thank you.
Ps. Any thoughts for good noise reduction?
Love you all.

The file is probably too big for your computer hardware to process in real time. Other than file size, there can be color management issues when using 8-bit RGB if the source or delivery codecs are YCC.
Standard file formats are 10-bit, all intra-frame, 4:2:2 or 4:4:4 codecs such as the lightly compressed ProRes, DNxHD, AVC-Intra, or Cineform; or uncompressed YUV, V210, or DPX. If you are OK with 8-bit RGB, then PNG or JPEG2000 images sequences offer lossless quality at much lower bitrates than uncompressed (but are difficult to play in realtime).
When considering the overall workflow, you should also consider nesting the sequence into a new sequence or importing it into a new project. The advantage is that you don’t need an intermediate file. The disadvantage is that all the effects will be rendered upon preview or export (but preview files and smart rendering can help with this).

Thanks for the response! The second part regarding nesting I understand. The first part flew over my head a bit. So I can just export as a new project and the sequence will enter the new project as one long clip? Thanks again.

Yes, a sequence can be inserted into a new timeline and Premiere will treat it like a clip. Within the same project you can create a sequence and then drag the old sequence from the Project Panel into the new timeline. Alternatively, open a new project and import the old project as though it were a video. The assets and timelines from the old file are now available within a separate bin in the Project Panel.

Awesome! Thanks so much that changes everything!

Premiere doesn’t have any problems with uncompressed footage. You just need a pretty darn fast RAID for reading uncompressed stuff.

I see you’ve gotten some other very good answers, but I just wanted to add this: Premiere Pro supports “smart rendering” [link] for several different formats.
With smart rendering, there is no generational loss on export. The compressed frame data is read directly out of the source container and placed into the output container, without being decompressed and recompressed. In other words, smart rendering copies frames without touching them.
If your source footage is in one of the supported formats, there’s be no benefit for straight cuts exporting to an uncompressed format when you could smart render instead.
