Hi, I shoot most of my footage with a Gopro and all the output is progressive. I transcode all my footage in Cineform and conform it all to 1920x1080 but leave the frame rates ( could be a mix of 25/50 and 100 and slowmos) as they are. I set my project in Movie Studio to 1920x1080 progressive @25fps. Sorry, forgot to say I am using Movie Studio Platinum 12. I always render to Main Concept HD 1080 Internet using 2 pass VBR at an average of 8 MB since my videos are mainly played on a PC and uploaded to You Tube. I also own a Sony Handycam and the highest quality outputs from that are AVC HD 1080/50i. ( 1920x1080). On occasion I need to integrate footage from that together with my progressive Gopro footage in the same project. I have to say regardless what I do, footage from the Handycam, is not a patch on the Gopro output with low levels of contrast and saturation but most annoying of all a seeming inability to capture any movement clearly. I can deal with the contrast/saturation and have been experimenting to see how to get the best results within Movie Studio. I appreciate that my judgement of the footage is based on what I see on a PC media player ( VLC) and in the Movie Studio preview window rather than on a TV. VLC produces the best player results with Yadif set as the deinterlace mode...which of course is not an option in MS. I am not sure what MS does in background, but since my project is set progressive I assume it is automatically deinterlacing the AVC HD clips ( presumably using Blend). When I check project properties I see that Field Order is set NONE and Deinterlace is set BLEND. I note however that besides the project property you can also access properties per event ( right click). When I do that I see the settings are Upper Filed First and the pixel size is 1.333 rather than square! I have tried changing all of these and cannot see any difference! Setting Resample to Smart for the interlaced clips does seem to make some difference however ( compared to disable). OK so after all that my question is, what is best practise here to get the best resulta from the interlaced clips in among my progressive footage? Thanks.
