silly doubt
Hi,
I just actually realised that I’ve never asked myself this question since I’ve been Switching to MC:The transcode from lowres to highres is taking into consideration the files selected or the source file?
What does Avid takes into account for transcoding ? The source files or strictly the media grabed?
(thinking that the timeline media is in this case of a lower quality)
Taking an ex with AMA: got prores media on a bin and all those media transcoded to dnxhd36 on another bin. Edit done with the dnxhd media. Client does not want a conform to the prores but instead to a highres dnxhd flavour, so new media will have to be created,
But from what then? that’s where my doubt remains.How the app “thinks” in order to keep the best possible quality?
I mean, the created dnxhd36 is a created media for fast and stable
Editing. If I grab those
Dnxhd36 and want to transcode all to a higher
Dnxhd, does Avid “understands” that it has to
Transcode from the source
Media (in this case prores)
Or does it uses the dnxhd36 as the based file?Fred.

If you transcode the DNxHD36, it does not go back to the original camera files. You need to take the sequence and relink to the original camera files by removing or hiding the Avid MediaFiles. Check the Avid AMA guides on the website for some workflows.

Avid references the source.
Here’s how it works. You use AMA to point Avid to the raw source. You transcode that to low res, say DNx36. You take the source offline and edit away.
When you lock picture, you re-attach the original source files. You relink the final locked sequence to the source files by relinking to AMA. This makes a new sequence that points to the original files. You then transcode to a higher resolution, say DNxHD 175 or 220.

Thanks Michael.
You confirmed my so-far practises.
In fact, I always thought it was like that, but I suddenly
had this moment of doubt, you know when we suddenly ask inside
“and…if…”Ahhh…the mind.

Thanks Shane,
Yeah, it’s totally stupid to transcode to Highres from the 36. Never did that before.
But today, I came with this doubt on Avid implementation,
it could well have been possible that the app, would automatically pointed to the higher source file when it knows that the media you want to transcode from is of lower quality than the target.
I always thought it wasn’t the case, but you know…and if and…maybe.
That’s why I called my post “stupid doubt”.Fred.

[Michael Phillips] “by removing or hiding the Avid MediaFiles”
no need to remove or hide the proxies anymore.Not exactly sure when this changed but can just open all the AMA bins, highlight all the clips you want to relink, also highlight sequence and then relink w/o having to have all the proxies offline. Its come in handy more than once, when something that was supposedly locked, indeed wasnt and needed some more work or comping.
