Re: [Avid-L2] Export as source - reimport via AMA - cripppled?

Hm. Indeed, we imported Bars&Tone (from the fkna but now EOL competitior.app) but those were transcoded into DNxHD 185 X, too. So everything in said sequence is in DNxHD 185 X. But I think you have a point here, so I dug a bit deeper and did tiny segment exports of different parts.

To me it now looks like the dissolves at the beginning and at the end of the program are causing the export to be "Avid DNxHD Codec" instead of DNxHD 185 X (1080i).
Additionally said Bars&Tone got imported into DNxHD 185 X but when exported from the sequence it looses the "X". I don't mind since the Bars in this case are only for a visual audio-queue and not for reference, however, getting them dumped to 8bit is not what I expect here. Media Creation is set to 185 X btw.

So: even if all is set to 185 X it appears the final export will contain three different Codec-types: "Avid DNxHD Codec" (whatever that's supposed to be) on the render files, "DNxHD 185" on the imported and transcoded Bars&Tone and "DNxHD 185 X" on our multicam recordings.

Maybe I need to rephrase my question then, it looks like "Same as Source" is not sufficient for this task - creating a QT-setting "Custom" and then switch do 185X does the job.

The standalone is done by experience: quicker (in copying) - and we were under some time-pressure here...

Thank you guys!
