HDV,10bit Timeline & Effects Rendering
Hi, I have an hour Long doc, shot and Cut in Apple HDV Timeline. My eventual delivery will be to DigiBeta via SDI.
If I drop all my final sequence into a 10bit timeline and do grading and effects work here, will my output be of better quality as I’m working in an uncompressed timeline? Or will it make no difference as the Media files are still HDV, just in an Uncompressed work space.
Thanks in advance

You may have some artifacting from downresing and letterboxing (assuming your footage will be letterboxed and not masked), so if you’ve got the the storage and the machinery, it’s probably a good idea to go ahead and covert to SD. Your graphics will most certainly suffer from the compression of HDV albeit nowhere near that of standard def DV. You also may want to experiment with QT conversion on a short piece of media before commiting to the whole timeline.

So, convert the timeline via quicktime conversion or after effects from HDV to SD before any grading? Or do you think grading in HDV will be fine then Convert ready for final output?

Neither. Just drop it into a 10-bit sequence and render. THEN add graphics and text.
In the future, it would be wise to capture the footage thru a capture card in the first place, as the AIC (Apple Intermediate Codec) compresses your already highly compressed HDV footage even more.

Hi Shane
It was captured native HDV not AIC, or does dropping HDV into a 10bit sequence add AIC?

Sorry, you said Apple HDV codec, so I made a false assumption.
No, it does not convert it to AIC…it converts it to Uncompressed SD

phew.
So, is my HDV footage in my uncompressed timeline still subject re compression when rendering as I\m still referncing the original media? Or does putting it into the Uncompressed timeline actually make it uncompressed once rendered?

When you drop it into the uncompressed timeline and render, you master footage is still HDV. the new render files that are created are the uncompressed media that the sequence is now referencing.
