What to do when you get a preview preset codec error in Adobe Premiere Pro CS6

This may even work on earlier version but I’ve only seen it happen in Adobe Premiere CS6.

I’ve been using a friend’s computer to edit my feature film, Amnesia, and I hit this snag a couple of times. This is my workaround.

No sequence preset preview file or codec

The error I get reads:
This project contained a sequence that could not be opened. No sequence preset preview file or codec could be associated with this sequence type.

Because .prproj files are nothing but XML files, you can open them up in your friendly neighborhood text editor (I like notepad++), and all you have to do is search for the sequence that is messing things up.

Actually, what you’re looking for is a line inside your sequences.

Offending Code in Premiere Project file

The offending line will look like this:

<MZ.Sequence.PreviewRenderingPresetPath>EncoderPresets\SequencePreview\5b1734e9-72dc-4a5d-82ad-f03102903125\P2 1080i-1080p 60Hz DVCPROHD.epr

All you have to do is replace the offending codec with one you know works for sure. On my system, the above codec works (from my HVX200/DVCPROHD).

So, do search on MZ.Sequence.PreviewRenderingPresetPath and you’ll probably find one like this, which is what causes problems on my system:

<MZ.Sequence.PreviewRenderingPresetPath>EncoderPresets\SequencePreview\9678af98-a7b7-4bdb-b477-7ac9c8df4a4e\I-Frame Only MPEG.epr

Replace it with a good preset, and you’re good to go – replace the highlighted portion with:

EncoderPresets\SequencePreview\5b1734e9-72dc-4a5d-82ad-f03102903125\P2 1080i-1080p 60Hz DVCPROHD.epr

Save the file and it should now open in Premiere. If not, then you can always look for more offending presets.

    Hi Val,

    I have just encountered this problem on a large project, very painful.
    This is probably a stupid question but how do I save the file so I can open it in Premiere after I replace the offending line etc?
    Obviously the file from the text editor is a xml file so how do I make this a useable file for premiere? I’m lost sorry.
    Thank you so much.

    Sorry, Val, please ignore that last question, I have resolved that problem.
    I do have another query though, I replaced the offending line as instructed but still no joy. How do I find a codec that I know will work for sure?

    hey Johnny, sorry about the late response, but I’ve been out of the country and just got back.

    I would open a project file that works fine, and then see what codecs are in there and use that.

    Let me know if that works. Otherwise you can send me the file and I can try and recover it for you!
