Entree Rep: 0 Joined: 11 Jul 2004 Posts: 3 OFFLINE | Hi guys, just new to this video editing. I have done a project in Adobe Premire and exported it but the file size is huge. I now belive you can get compression sorftware for this. I think i didn’t use any compression when I exported this.
A few questions
1 what would you suggest
2 do you install this as part of premire and use it when you export the video
3 I am wanted to do a DVD quality so what format do I use.
Thankyou very much in advance, you might have already answered these questions a millions time before but I have to start somewhere.
Thanks again.
Coxy.

anonymous Guest | Note - this is purely subjective - different people may have different opinions on what codecs to use, but the most important factors are the actual video you’re converting and the end size/quality you want.
1. If you want purely quality and size isn’t a factor you have two options: a. with avi’s use the huffyuv (often abbreviated 'huffy') codec. It’s a lossless codec, but very few people have it or use it. (it definitely beats the huge uncompressed avi you have!) b. use mpeg-2
2. If size is still too big you could use one of these three: a. divx 5 (from divx.com) - you may want to get dr divx to get all and the highest quality encoding options b. xvid - an open-source mpeg-4 alternate to divx ( http://www.koepi.org ) c. microsoft mpeg-4 version 3 (hacked as divx 3). the best at reducing size. microsoft hasn’t unlocked their codec for avi encoding but you can get a hack here http://www.undercut.org/msmpeg4/ or the divx 3 hack here http://divx-digest.com/software/divxcodec.html
3. some proprietary formats that also have good quality are a. sorenson 3 - to make quicktime movies encoded in sorenson 3 you would need quicktime pro. b. one of the windows media video codecs (7, 8, or 9) I haven’t tested them much to recommend a particular one - my only reserves are that this is proprietary (not portable to all platforms, like unix for example) and the fact windows media video files need to buffer before playback / seeking is awful.
4. just thought i’d throw this in. if you want something that’ll play in ANY computer (mac, unix, pc, other) use mpeg-1.

Now I tryed Dr Divx and it seemed to have dropped the qualitity heaps.
Question is should I be converting my files to a MPEG2 file for the best results. then I need to find a MPEG2 decoder. Any ideas on where to get one of these from.

anonymous Guest | The person playing it back would indeed need an mpeg-2 decoder. There are several solutions
1. (My favorite) Get Media Player Classic from http://www.gabest.org
2. Get DVD software (PowerDVD, WinDVD, etc) These are usually pay though.
3. Get the Elecard MPEG-2 decoder. I was looking at their site recently and it seems they now require your e-mail and stuff. Maybe there are other free decoders out there. You can try unearthing them with a google search.

What were your original video files captured from?

Entree Rep: 0Joined: 11 Jul 2004 Posts: 3 OFFLINE | Well thanks again for your replys, so far I have worked all this out.
The files are from a DV camcored so that’s why they are huge and then taken into Premire to edit them and exported files as a DV video file AVI. I tryed a few compressions programmes but lost too much qualtity (Divx, Sorensen). I have found out that although these files are big when I use Ulead to put them onto a DVD they reformat them into a MEG2 file making them alot smaller (700m to 110m).
But when you look on the DVD after they are burnt it’s called a VOB file.
Question what is VOB.

“VOB stands for DVD Video Object. It is basically one of the core files found on DVD-Video discs and contains the actual movie data.
Basically VOB file is just a basic MPEG-2 system stream — meaning that it is a file that contains multiplexed MPEG-2 video stream, audio streams”
if you buy a commercial DVD and pop it into a dvd drive and look at it using windows explorer you’ll find vob files. (usually the ones on commercial dvd’s are encrypted though). The system streams contain the video stream, and possibly audio streams of different languages. I guess it would be up to the dvd player/software to play the correct portions.
