I decided to work from an external disk with all my back-ups after a crash of an internal HDD. AMC opened the project without problem and relinked automatically to the Media Files. This lead to some new observations. I mean new to me. Forgive me if what I say here seems from a dummy.

My project is a HDV project, but every single clip, before I bring it to the timeline, is transcoded into TR 120. I suppose that all transcoded files are stored in AvidMediaFiles and that the original 1080i footage is no longer linked to or even needed. Am I right? Could I even delete the original HDV/1080i clips?

I would be happy with a short answer. For you its not much trouble. Anyway, its not that stupid to ask this, because the way Avid stores its transcoded-consolidated-computed files is not very transparant.

Yes, you can delete your old origin captured media once it is transcoded to DNxHD, it is always able to restore it from tape using batch-digitize if you need to in the future

And you can verify that this is true by using File>Reveal file on both the original clip and the transcoded clip - reveal file will show two completely different coded media files.

I also prefer to have the sequense option to show clip properties activated, just to be sure of that I haven´t forgotten something

I was doing File>Reveal and I bumped on some questions.

In MediaCreation the Importsettings are set to TR 120. In AvidMediaFiles these imported files appear as MXF files. When I directly (without transcoding manually first) drag one to the timeline, it appears there as a HDV clip. What is the use of the MediaCreation Import settings if it doesn't effect the footage (it remains HDV). Or does it?

HDV is a format that is not native to the Avid environment, so the resolution on import will be HDV regardless of the resolution choice in media creation settings. Most users have found that immediately transcoding the imported files to a DnX resolution makes the entire editing process go much smoother than staying in HDV.

After import I need to make subclips from the HDV clips first before I transcode those subclips to DnX. I need to do that because they are full with corrupted parts, especialy at the end of the clips. I guess it is because I was capturing with HDVSplit. They are M2t files.

But you are absolutely right. In the beginning I worked with the HDV clips in the timeline and that gave me lot of trouble. With the transcoded clips It goes much smoother.

Why is HDV not native to the Avid environment?

Sony designed the codec from the point of view of minimising storage space and not from the point of view of ease of editing.  For that reason any NLE that I've used handles HDV media better if you transcode it to a native format, ie., ProRes for FCP or DNxHD for Avid.  So I repeat: you don't have to transcode it, but it helps.

Ok, thanks for the info.

You're welcome.
