deinterlacing 50i project for Internet
Hello there ,
I have been stuck in this for over a day and read many things across the net and still haven’t reached a satisfying solution.I am editing 50i video shot with an old Sony hdr-sr11.
I use the “set project settings from media” button.
I render with main concept Internet 1080p
When I first saw the jerky results of deinterlacing via either blend or interpolate I thought I had done something wrong.Looks almost fine when the camera doesn’t move but the moment it does it looks bad. nothing like the original footage.
What do most people do with interlaced footage for YouTube . How do they get smoother motion ?
This must be a common issue even for people shooting in 60p because they too need to convert down to youtubes 30fps limit and lose half of the frames. Yet I can’t find any satisfactory information.
here is a test
im well aware the camera is shaking but the with the original footage this is tolerable. it looks nothing like this

[luke massoud] “I use the “set project settings from media” button.”
Did that correctly set your project to HD 1080-50i (1920×1080, 25.000 fps)? because it should have. Make sure that the Field Order in your project is Upper Field First.
[luke massoud] “When I first saw the jerky results of deinterlacing via either blend or interpolate I thought I had done something wrong.”
So it is impossible to get interlace artifacts when setting the Deinterlace Method to Interpolate Fields because that mode throws away one field leaving you with only one field and half resolution. There is no more interlacing at that point.
BTW, I did not see any interlace artifacts in your video. All I saw was poorly lit, shaky video. Interlacing artifacts would look like the teeth of a comb at the edges of moving objects. I didn’t see that.

John thank you very much for your reply. I think you are the most helpful person on the Internet. You have answered all of my posts on here and helped me out and I very much apreiciate it.
I have no problem with interlacing artifacts (mouse teeth, combing etc) . My problem is the “smoothness of motion”. The original footage is very smooth(the smoothness is noticeable even in that shaky clip I posted). I’m finding the motion vastly inferior of the 25p render .
here is a better example maybe ?

the motion was butter smooth. now to me it looks like its lost allot of fluidity.and here is a better example of a smooth youtube vid:

I’m not sure why you would lose fluid motion. You didn’t change frame rates so you should have the same motion although 50i does sample twice as many fields as 25p, you shouldn’t see that much of a difference.
Did you use Blend or Interpolate for your Deinterlace Method? Try using Blend if you can because it will retain more resolution. Perhaps this is what’s not looking correct to you?
