Source video: Gopro 1080 @50fps ( h264/aac encoded): Intermediate video: Gopro Cineform Studio (original settings retained) Editor: Movie Studio 12 : PC Intel i7 3770 16 GB ram Nvidia Geforce GTX 660. I have spent time searching around this forum and identified some clues but not sure I have found an answer so would be grateful if someone could give me some advice on the following please. I am using a Gopro Hero 3 action camera and can successfully render good quality footage on most of the camera settings including 2.7k but I am having problems with 50fps footage. In this case 1080 @50fps. My rendered video has none of the crispness and lack of blur of the original footage. It is not bad but if for example I freeze frame the playback it is quite difficult to find a really crisp frame. My workflow is to import the camera footage into Gopro Cineform Studio, retain the settings and transcode to Cineform AVI. That is imported to Movie Studio and the project settings set using match media to that clip. MS12 does not suggest a matching render so I have tried Mainconcept HD1080 with the template only modified to replace VBR with CBR set at 20MB ( Hero 3 uses variable bit rate up to 45MB/sec and it is "guessed" that the average for 1080@50 is 20 to 25MB/sec). I choose my renders for playback as a file on my PC ....then use that file for upload to You Tube and conversion to Bluray for TV viewing via a USB port on my Blu ray player.
