[Avid-L2] Re: Transcoding Gotcha I found out the hard way with Convert Audio Checkbox

 

Well this morning with a clearer head I'm back at the so called one button process that just happens over night by itself NOT!!! I don't know if I missed them or they were lost but now several of the reels, uh Cards, don't have Tape Names that I thought I put in. Even going back to the original ama bins doesn't have them so F me skipping I probably messed up there. Also a couple clips have lost there audio. Oh well 2 out of 400 plus isn't so bad and the audio is there when I relink to the original ama clips.

Now here's the new kicker Roger. I found in redoing the clips with missing audio when I do the original ama transcode to DNX 220 I didn't have to check the Convert Audio box and the audio came accross on the new clips. It is only when I later go to transcode the DNX 220 to DNX 45 that I have to check the Convert Audio box. From this I figure that Avid handles the initial ama transcode to DNX differently the subsequent transcode. That seems a little asymmetrical to me but what do I know? After all I didn't spend all night doing it wrong, uh oh wait..... ;-(

Now my instinct was to just check the Convert Video and select DNX 45 after all I'm just converting the video and doing nothing to the audio as far as conversion. Well I moved the new media over to the original project on the offline system and voila video no audio. WTF. Turns out the Convert Audio Checkbox actually enables the audio to be part of the transcoded clips so checking it and leaving it at 48K for my sources is the correct thing to do to get all the tracks video and audio onto the new low res clip. Now here's the gotcha that caused me a moment of sheer panic. Without me realizing that the transcoded files were playing audio from the original files and not the new ones I'd created I figured I'd just delete my transcodes and start

Ouch big time especially because this was the only source I didn't have original card media for. Fortunately I had previously copied the clips to a third drive so I was able to find it there and replace it back on the original drive. When I used reveal file I got a prompt the video and audio were on separate drives but when deleting the transcoded clips there was no such prompt or warning.

I'm sure this has come up before but it obviously didn't stick with me until tonight. Hopefully this will save someone else from having a massive tush pucker like I'm still recovering from.
