Forums Compression Techniques MPEG2 from Compressor not for DVD

    Hi there,

    I need to create an MPEG2 file for a presentation on a big screen. The location tech people have requested MPEG2 [broadcast res], but specifically not a DVD. Compressor only seems to create MPEG2’s in the split format for DVD encoding.

    I haven’t done this in a while, but isn’t it possible to create a regular MPEG1-style file using MPEG2. I’m sure I’ve done this with Cleaner, however I haven’t got access to Cleaner for this job.

    Just output a mpeg2 with Compressor, the tech will probably read it with a mpeg2 reader. Or he meant a muxed file (Compressor 1 can’t do that), so you can create a simple DVD with DVDSP and rename .VOB file that represents your track to .m2v or .mpg.

    Hi Pete,

    So what you’re saying is that renaming the Compressor file from .m2v to .mpg will do the trick. How is it possible to keep audio with the file, do you know? Or is Compressor not suitable for this. I’m pretty sure Cleaner could do that.

    Or pehaps Quicktime Pro?

    So what you want to do is encode your video track to an M2V and then export the audio to an Uncompressed format (either WAV or AIFF). Then, you can either mux the two together in MPEG StreamClip (the audio will be registered as PCM) or you can mux them with BitVice Helper, which will encode the audio to MP2 and then mux the video and audio together, saving you some disk space. They would likely prefer the PCM audio version however.

    I’m trying to do the same thing- make an mpeg2 movie that will be played back from a ddr onsite. I’ve used Compressor2 to encode my video. I have anamorphic footage currently in dv codec.

    I modified one of the “best quality 60min dvd” settings. I tried to output using 16:9 as the setting, but it smooshes it to 720×405, not the 720×480 I’d expect. So then when I try to keep it at 4:3, it keeps outputting it at 640×480. I’m trying to keep the highest resolution possible… what am I missing?

    When you encode to 16:9 anamorphic, it is in fact encoding to 720×480, just that QT recognizes the PAR flags and will display the content at 720×405 automatically. No need to worry, your original 16:9 encode is fine.

    So are you telling me that it actually is 720×480? I’ve tried looking at it in FCP, and it tells me that the file is also 720×404. Quicktime tells me 720×404. I just want to get the most pixels possible- 640×480 has more pixels than 720×404. thanks

    If your source PAR was 16:9 and the anamorphic size of the source is 720×480, and you encode to 16:9 anamorphic MPEG-2, Compressor will encode it at 720×480, but QT and any other app that uses QT for decoding will report and display the video at 720×404. To get better info stats on your encode, download and use MPEG StreamClip.

    Thank you, that makes so much more sense and my world is no longer shaken up.

    Why does quicktime display it that way? Is it trying to help in a consumer kind of way? I’ve also had the problem where I’ve exported video and in Quicktime it shows a huge color shift. However, you open the same file in After Effects or another program like Keynote (where it was destined to play back) and it looked like the original file in final cut, without shift. Very frustrating.

    So, when testing files that you’ve made, is there anything key that you include in your process (besides checking the file in a program other than quicktime?)

    Thanks again
