    8mm home movie film Telecine specs? & 23.98 Avid project or 24?

    Hello all, I'm in the process of getting 60 year old home movies professionally transferred by Pro8mm, with the plan to make a documentary short from them.

    Pro8 has a wide range of specs available, and before I commit to getting 3hours of footage transferred, I'd like to get a sense of what's ideal?  NONE OF THE FOOTAGE HAS SOUND. 

    They have a lot of framing options for the telecine, which are here... https://www.pro8mm.com/pages/4-framing-options-for-data-scan

    Within my budget, they offer a Production scan with the following specs available: -2048 x 1080 2k DCI  (or 2048 x 1556 2k 4x3) -Log Color Timing -Playback frame rate (UNSURE... 23.98 or 24??) -Image frame (UNSURE 16x9 or 4x3?  with Full Format Overscan)
    -Codec:  ProRes 4444.
    I was thinking of the 16x9 full frame overscan, to keep things easy, that way i don't have to do further blowups within avid and lose quality. I'm unsure about what frame rate to have everything telecined at, 23.98 or 24? They advised 24. 
    8mm tended to be shot at 18fps, so I'll be doing motion effects throughout, regardless. I'm having a small test done at 24, 16x9 with the full format overscan. 
    Any advice? I'm having 5,000 feet of film telecined so I'd like to get things right!

    Best,
    David

    As a former super8 enthusiast....

     

    1. The frame rate is likely ~18. But old home 8mm cameras were not frame locked. It was all mechanical and fluctuated wildy (14-22 fps). I recommend 23.9 or 24.00. What ever works easier for you.

    I recommend using the MovieStuff method instead

    Scan each frame cleanly. No locked frame rate. You will get an image still sequence.

     

    Though Pro8mm often services Hollywood productions.

     

    2. Resolution wise, 8mm was not very good. I doubt you will resolve anything higher than 720p. Super8mm using Kodachrome 50 was better. But 8mm film stock @ISO 100 or higher will not resolve 2K. Super16 was just about 2K.

    Dom gives good advice.  I will throw my 2 cents in.

    1. Frame rate.  I would get them to transfer 1 film frame to 1 video frame. The frame rate embeded in the file should be whatever your project frame rate will be.  The reason for this is that you do not want to be fighting an embedded pulldown pattern in the transfer.  With a frame to frame transfer you can more cleanly set the motion speed of the images. Dom is saying the same thing I think.

    2.  Here I diverge with Dom.  I would scan at as high a res as you can afford, makeing sure that no image is lost, but not much more.  This will let you push in and reframe with less appreciable image loss.

    Here is one opinion on that front:

    I recommend you read throught Gamma Ray Digital's whole site.  Very knowledgeable.  And helpful people.

    Good luck,
