Re: [Avid-L2] Europe here calling: p50 -> p25 - i25

Mark - 

Sorry to say, but: nope.

QC on the side of the TV recipient (broadcast, not: streaming) WILL throw back intra-frame edits.

This in mind: a proper setup on source p50 -> chaning Avid to "Edit Timebase 25" can fix this. However: if MultiClips are involved and as there is a 1f offset in-between the ISOs and the PGM in the 50 raster - is i good enough to keep the timeline-edits in the 50 raster at ":"? Knowingly: that 1f offset in-between the ISOs and the PGM wpuld not line up?

Is there a way to display a 50fps TC in Avid on the track read-outs or ist it just "." and ":" in a 25 counter instead of a 50 counter? What's gonna happen if we go 100/120 fps?

Avid, you read this?

Best

However, if you have an interlaced delivery, and it is going to an interlaced playback platform, then having those blended frames (edits with a frame of one shot and a frame of another shot) are OK. You may be thinking that you need to keep all those edits "clean" but that can be torturous to maintain. I would, as Knut said, edit in 50p and finish in 50p, and convert that 50p master to 25i at the end for that specific delivery. If that delivery is asking you for clean edits on your interlaced frames, it then becomes clear that they intend to subsequently re-encode your 25i air master for 25p web/streaming, and they can go to heck.
