I have been doing some tests shooting railway subjects prior to setting out to do the real thing. I am using the Blackmagic Pocket cinema Camera, grading in Resolve and performing audio work, titling and edit in Vegas 13. My intention is to release these programs as high quality HD 1920 x 1080 with Dolby 5.1 surround sound.
My first attempt was spoilt a little by it raining just as the train arrived, but the results were sort of OK. Unfortunately I was not able to record the sound correctly, so it is only that picked up by the in-camera microphones. Actually, it is not all that bad. The delivered clip was rendered out of Resolve as a Quicktime MPEG4 clip at a high bit rate, and then further processed by Handbrake to make the clip a more manageable size.
For the second attempt, I got the whole audio thing together and produced a good audio result, but I am disappointed by the images. Resolve is a great grader, but cannot mix audio for nuts and does not have a capable titler. So I exported the images as a Quicktime YUV 422 10 bit file, and edited, titled them and mixed the audio in Vegas 13. And that where the problems arises.
When it comes time to render the output, there is only one codec offered by Vegas, Sony AVCHD, that can output the audio in Dolby 5.1 (as far as I can tell).
But the video performance is not great. To keep it within a manageable file size, I chose to render it at 4 Mbits/s, and I now find there are some annoying artefacts in the rendered image.
If you care to look, you can download the clips and view them here: http://www.hollywoodfoundry.com/film%20files.htm
The parts of the image that bother me includes the bush on the left of frame. From time to time through the clip, something seems to be possessing the bush, and also the dark green overhead foliage is badly rendered and flickering.
I would love to hear from any of you who can suggest any way to improve this.
