And also, if NTSC and PAL both use rectangular pixels, at what point do square pixels get utilized. As mentioned in your first post’s link, is that 640X480 only for computer monitors?

[Dan Freshman]

Yes I understand that. But not really what that implies…Does that it was shot on footage that used rectangular pixels and that be converted? If not, doesn’t all footage have an equivalent in square/non-square pixels, why can’t It be one or the other, not both?

That doesn’t work. I get the same multiple track listing in the properties window and both resolutions still exist in the inspector window.

Are there any settings that would be different for a quicktime export to make this work?

QTCoffee is a collection of command line applications for manipulating QuickTime movies They can join (concatenate), multiplex, and split movies; they also perform various modifications and editing. https://www.3am.pair.com/

The resulting concatenated movie is just a reference file and does not create a fresh new movie. I then bring my movie into DVD studio pro and when I drag this asset into a track, the clips with resolution discrepancy do not show up and my video and audio tracks do not line up.

thanks for posting that link, it was helpful in learning about this issue and PAR, however it does not exactly solve my problem.

I am working on a project where we are concatenating a series of movies in Quicktime Coffee and if the resolution is off, we encounter problems down the line. Specifically you can see in the properties of our concatenated movie in quicktime that if we append clips that have that different figure resolution: “Format 720×486(640×480)” in parenthesis then we end up with multiple audio tracks and multiple video tracks in the quicktime clip properties window. This is what causes problems.

Anyone have any explanation or fix to this?

thanks

Thanks for the help Michael. It has been useful. Sometimes however there is degredation that is worse when we use compressor and AC3 audio. The audio is fine, but there is definite loss in video quality. We have the same settings in compressor as in DVDSP but with of course, the audio compression added and seemingly more bit rate space for video. Any ideas where loss of quality would be entering the picture?

we re-encoded in compressor and their was improvement in quality. So the basic idea is video bit-rate data is sacrificed for audio compression in DVDSP? Any idea what DVDSP compresses audio w/? There are no audio options in the encoding preferences window.

The drives aren’t asleep, they are local…So you recommend encoding in compressor or final cut before bringing the files in to DVD studio pro? I have read that the engine on DVDSP is basically the same as compressor, but with less options. I have come across some compression related problems throughout this process going from Photojpeg to mpeg2. Does anyone recommend a better process?

found thread w/ help. I apologize for posting!

Thanks for the replies. I have streamclip, and that takes me back to my original problem of converting the mp4s to anything creates huge files, a 10mb mp4 becomes 200mbs when converted to anything. Or just bringing it into FCP as is, creates huge render files. I guess i’m looking for advice on how to work with massive amount of mp4 broll footage w/out creating huge needless render files/converted files. In essence, a preview mechanism in final cut or something similar.

Thanks again for all the help and advice,
