Uncompressed AVI causing playback problems
Hello,
I’m trying to render my footage as uncompressed clips because of my Premiere Pro problem (https://forums.creativecow.net/thread/3/895456 and https://forums.adobe.com/message/2198228; if you have any idea how to fix it please post at those threads, thanks!).
I chose “Video for Windows (*.avi)”, “Default Template (uncompressed)” and rendered and I can open the avi in KMPlayer without any problems, only that there are horizontal lines across and the resolution is too small.
So I modified the Default Template to “HDV 720 (1,280×720)” frame size, “None (progressive scan)” field order, 1.0000 pixel aspect ratio and rendered. However when I tried to open in KMPlayer, I got this:
I tried using the Default Template (uncompressed) again and it works fine. I then experimented by using the Default Template (uncompressed) but I changed the frame size to “HDV 720 (1,280×720)” and once again I got the error.
So why is the frame size causing all the errors?

Update: Now both Default Template (uncompressed) and my custom one lags while playing. I tried opening in Quicktime, it lags horribly too. Just that for the custom one, the pop up error appears.

Uncompressed HD video is huge. Unless you have a RAID 0 with at least several (more than 2) disks you can forget about smooth playback.
Perhaps if you could explain what it is you are trying to do (i.e, what problem are you trying to solve) someone can offer a solution. I see no reason to render uncompressed video.

Yeah I kind of figured out it’s the huge bitrate (600MPBS) that’s causing the choppy playback.
Well I wanted to import uncompressed footage into Premiere, but anyway I got that now. I exported into mp4 and the quality’s great and it doesn’t lag.

The Apple Quicktime Animation codec is lossless and also carries an alpha channel and is great to use instead of uncompressed. Both the HuffYUV and Lagarith AVI codecs are lossless and smaller than uncompressed. Finally, the CineForm HD intermediate codec is exceptionally good in places where you would normally use uncompressed for high quality although it is a lossy codec. So there are several alternatives to uncompressed that give just as good quality.

Oh, and isn’t the Quicktime > Animation loseless? Because I’m trying to render a portion of a clip to fast-forward in After Effects (I want to keyframe so the speeding up and slowing down is smooth) and I rendered it in Animation preset and when it came out there is slight color loss.
I opened the rendered one in Quicktime player, the original one in KMPlayer.
Quality’s set to 100, though.
Oh and another thing. When I opened the rendered one in both Quicktime and KMPlayer, I discovered that the colors are all weird and wrong. It’s like negative. The skin tones are bluish and it’s all the wrong colors. But black remains black.
So any idea on 100% lossless and fixing the color problem?
