    I'm trying to burn some material to DVD which I came by in Video_TS format. Realizing that DVD Studio Pro cannot import .vob files, I put said files through MPEG Streamclip then duly imported the (now) Quicktime file into DVD Studio Pro. But now the 23m minute long telly clip has ballooned into a nearly 10 gig leviathan! How am I ever gonna fit that on a DVD? And even it's not even the sole clip I wish on my DVD comp! Can some kind soul please advise? Many thanks!

    Video DVDs use MPEG-2 as codec and use the .vob container to encapsulate the video and audio. Due to the MPEG-2 codec, DVDs with 8.5GB can store up to three hours of good quality video.

    When you used MPEG Streamclip to transcode the video DVD's content, you must have selected some codec like Apple Intermediate Codec (AIC) or ProRes and the .mov container (CMD+E > QuickTime), and as the smaller MPEG-2 encoded video does not store every frame, only every 15th, and the ProRes and AIC store every frame with less compression, you get bigger files.

    Now you have to use Compressor and the appropriate DVD template to transcode the video again and then use those resulting .m2v and .aac files in DVDSP to make your DVD.

    Please also consult the manual of DVDSP as it has some valuable information and got me running when I started with that application.

    Easiest way is to open in Compressor and use the "DVD: Best Quality 90 Minutes" setting to transcode to the proper codec. Import that into DVD Studio Pro and you'll be all set to make your DVD.

    Thanks chaps. I reckon then I should go back to MPEG Streamclip and transcode it differently? What it is, I have that 30m clip which I want to add to 60m of my own camcorder footage, so I need to leave enough space for 90m of decent quality footage on my resultant DVD. Can you give me any tip on converting the telly thing in MPEG SC? To make matters worse I'm currently exporting my camcorder footage from iMovie so will I not end up with another humungous QT file that's too big for DVDSP? Arggh-any ideas? How do 500mb and 2.5gb files respectively end up taking so much space anyhow??

    You were almost there.

    You need to use Mpeg Streamclip to Demux the video. This is a very fast process and you won't lose any quality (unlike the other methods).

    Simply load your .vob into Mpeg Streamclip and choose demux from the File menu. You then choose the correct options for the type of video in your file (as no conversion is taking place you have to choose the correct combination of video and audio files - usually .m2v and .ac3).

    This strips the video and audio out and you end up with DVD Studio Pro friendly files with no transcoding or recompressing.

    Sounds good but will I end up with monster size files too big for one DVD?

    DVDSP Pref?

    I think you can lower the compression within DVDSP in the prefs.
    This way you can watch your ballooned data and see if it fits in a single disc.
    I've actually had success with dual-sided using DVDSP.

    Unfortunately video takes up space. And in some cases lot's of it.

    Luckily hard drives are cheap. Nowadays you can buy a 1TB drive for about £100.

    A hollywood 2 hour movie can fit on a single sided 4.7 GB DVD (as an mpeg2).

    2 hours of 1920x1080 ProRes HQ is about 170 GB

    2 hours of Standard Definition DV is about 25 GB

    2 hours of Canon 5D .h264 is about 35 GB

    2 hours of 1920x1080 Apple Intermediate Codec is about 80 GB


    As I said before - you don't want to recompress your video. You lose quality everytime you do this.

    DSP Help

    The amount in gigs is not important when creating an SD DVD.

    Its the time length. A SD DVD can hold upto 2 hours of video in time burned as a DVD playable disc.

    Now if you are using a dvd disc as a data storage media. Then yes file size is an issue, you can put upto 4gigs of any type of file media you want.

    The difference is the way disc been created in the end.

    dvd help

    I forgot to mention that whether you use compressor or DSP itself to encode the video. It all gets compressed to fit on the dvd.

    The difference is with compressor you have more control over your settings.

    If you let DSP to the encoding its just going to take longer to make the disc the first time you build/format it. After that as long as you don't have to make any changes to the actual video and only to menu elements then it will go much quicker. It will just reuse anything that has not changed since the last build of the disc.

    That's not even close to accurate.

    4.7 GB.

    Again, not even close to accurate for Compressor.

    Do you just respond to things anyway you see fit or are you hoping for some kind of accuracy? Because if so, you are terrible at it.

    Post #5 answers your question

    If you have 90 min of footage, it should fit onto a 4.7 GB single layer DVD just fine. You need to take the VOB files from the Video TS folder and dump those into Streamclip and then "demux" to M2V and AC3 files, which can be brought into DVD Studio Pro. If I ever have more than 4.7 GB of material in DVDSP, let's say it's 5.0, then I make my DVD in DVDSP and "build" - make a Video TS folder. Then take that Video TS folder and burn it in Toast in the area where it burns those kinds of folders (not as "DVD-Video"). Toast will crunch it down to fit onto the 4.7 GB disc and does a good job of it. There's a checkbox setting in that VTS Folder Burn command area that tells Toast that the folder is too big and Toast needs to crunch it down. If you want to use Final Cut Pro, you could get the footage into that (DV-QuickTime), and eventually into Compressor, however you are talking about some reencoding. Sometimes I would do that however as a tradeoff for being able to do some fine editing that is very hard to do while keeping it MPEG2.

    Thank you

    Okay. I legit created an account at this forum for the sole purpose of saying THANK YOU. I have been using MPEG Streamclip for YEARS and have NEVER been told about the Demux feature. You have saved me. Not only for the project I am working on now but for tons of future projects. Thank you so much!!!!!!!
