Sorry to hear of the issue. Sounds like it might relate to source > output sizing... although streaming web codecs inherently make fine details such as grain mushy anyways. To help me answer better, please tell me your:
-- Source clip frame size
-- Final output frame size & bitrate
-- Web playback frame size

Hi Michael, thanks for the speedy response.
Delayed action from here in in the UK!.
This is source info for one of my typical shots from the Panasonic GH3:-

As previously mentioned I have tried most combinations of output formats and profiles from PD12 to try and get decent grain (I'm after the fine grain setting 0-1) although did try most of the available GrainPlus 2 settings, such as size, density, motion, colour, grey.
I tend to stick with the following PD12 custom render profile, as I find it provides a 'clean' image for my current film with few compression artefacts visible; however I would have to use slightly higher compression as my Vimeo Plus account is restricted to 5GB upload per week and my film is 7.32GB using this output profile:-

You will notice that the output frame rate is changed to 24fps rather than the original 23.976fps, this is required for the audio to remain in sync throughout the duration of the film, as for some weird reason rendering in PD12 to this custom profile causes the audio to drift by the difference of the two frame rates. However when trying GrainPlus 2 the ouput frame rate was the same as the source frame rate.
Not sure what you mean re- the web playback frame size:
I'm viewing Vimeo and YouTube playback on:
Display Graphics: Display adapter type 2X NVIDIA GeForce GTX 680M
Total available graphics memory 12011 MB
Dedicated graphics memory 4096 MB
Dedicated system memory 0 MB
Shared system memory 7915 MB
Display adapter driver version 9.18.13.4411
Primary monitor resolution 1920x1080
DirectX version DirectX 10
I do like the film grain shimmer, but may have to accept that film grain will be unsuitable for web display with this particular film (or any?), and just go for the non-textured look, but must admit that I'm making good use of your FilmTouch2 Pro plugin (subtle look) and the vignette - one consolation :
If you can give me any pointers of settings and codecs which will work on preferably the Vimeo platform, that would be appreciated, as I have some 'shorts' in the pipeline, which I would like to give a very artsy, flowing look, with plenty of larger grain akin to the 16mm film.
Regards
Lawrence
