Ok, I'm going to try and explain this as best I can. I run on Imac 10.5.8. I use final cut express 4 for my film editing and iDVD for my dvd burning (though I would like to eventually use Adobe Encore 5.5 to make a custom menu dvd for my film but we'll get into that later). I've just finished completing a film that has literally taken me 4 years to make. Its a quicktime mov file exported out of final cut express 4 in 640x480 resolution (the first footage we filmed started out that way as yea we didn't quite know what we were doing. I got a new HD cam and still used that footage but downsized those clips for my fx program visionlab studios, did my fx, exported those as raw animation files, then threw those into my final cut timeline so i'd keep as much quality in that format as possible.) Now that the film is completed, digitally in its mov format now (despite the fact that yea i could've started this project differently and had better results than now) At 92 minutes long and 12.5 gb of memory on the file, I usually have no problem burning on dvd-r (with 4.7gb space). However I've been trying to find better memory/playback options for a presentation I have in 3 weeks. I'm quite happy with out it looks on the playback on my mac. It looks "ok" on regular dvd-r's (dvd+r's apparantly never work through my mac). But at times, objects that are red in my film will either appear a bit pix-elated or have vertical lines through it. But when I play the mov file back on my computer, it looks all clean and crisp . . . I've tried flashdrives (even as a back up device) only to find that multiple sandisk 64gb flashdrives all gave me an "error code 0" and later discovered that files over 4gb won't load onto the flash drive unless you change whatever format it says you have to and even after you do that, you limit its playback capability. Is there a high memory mac flash drive that won't do that to me and won't require me to "jump through hoops" to make it work?? I also tried getting external bluray drives and software considering that blurays hold 25gb which theoretically would be more than enough and probably show the same playback quality i'm seeing on my mac here. Unfortunately there are a TON of hoops to jump through and other extra softwares you have to purchase after you get all that stuff as "unfriendly with blu ray that mac is." Eventually I just lost patience and returned all that stuff after I spoke with a blu ray authoring company and then they explained that not only would I have to back to Final Cut and re export it in a whole nother codec but also that my simple 480 file won't burn onto a blu ray either. So I guess that's out unless someone can provide me with a step by step process for an old OS X 10.5.8 mac to accomplish that since everything is now apparantly 10.6 and up now. Also DVD-R Dual Layers were suggested to me. I tried DVD+R DL's (as no retailer around me had the -R versions) just to see and i-Dvd was giving me "multiplexing errors" everytime I tried burning. Will the same thing happen with DVD-R DL's if I try or will they work?? Also if I were to go the Adobe Encore Dvd menu route for dvd copies to pass out, will my 12GB file burn onto either type of DVD-R/(DL) or will it not burn it the same way as IDVD and I'm basically stuck with iDVD and regular DVD-R's. Everyones telling me I should go back and just do a regular export of my whole film in FCE without quicktime conversion (but i'm afraid if I do that, everything will look wrong or pixelated as everytime I render my effects clips for playback the red objects look bad and unless I eliminate that render, the export brings out the clip to look that same way and I don't want that.) Either that or they tell me to make an iso file for Disk Utility or a VOB file which I'll be honest, I know NOTHING about as I've been going the IDVD route this whole time. I'm a guy that really needs things explained step by step as I don't understand alot of file types that well. So my big question (with all these circumstances is this). What options with my present equipment do I have to make a better presentation of my mov file film than regular dvd-r with iDVD burning???? Any help seriously appreciated.
