Before getting started, you can download the recommended multi-purpose converter via this link. In this article, two methods are offered for you to settle VLC CineForm conversion and playback issues. Maybe if you have very slow internet and really trying to do file as small as possible then you may not want CRF.Convert Video. For 1 HD file 20Mbit is plenty, for another you may need 50Mbit+ to get same relative quality. Using CRF is a good starting point (note that the CRF values are different under H.264 and H.265) or just use a fixed bitrate.ĬRF is better than fixed bitrate as it will adapt to your master encoding complexity (we are not doing BD so we are not directly limited by file size). Like Andrew said, the best workflow is to render to a good quality intermediate like ProRes, DNxHx or Cineform and from this intermediate generate an H.264 or H.265 delivery format. So you are saying the quality wouldn't make a difference since I'm uploading to youtube? what render formats could I pick to get use the parameters you are talking about? I did quite a bit of experimenting in Davinci with rendering but don't remember seeing being able to specifically limit the upload bit rate.
Premiere supports it also, so you can edit UHD files at 1/2, 1/4 resolution just after single click on a laptop like yours.Ĭary Knoop wrote:For 4K SDR I would maximize the upload bit rate between 40-60Mbps for H.264 and about 30-40% less for H.265 both codes using long GOP. No need for any low resolution proxy files etc- it's all down to simple setting in the decoder.
This is the beauty of Cineform codec which is wavelet based, so can be decode at fractional resolutions at fractional CPU needs. If you double click on Cineform decoder then you can set Full/Half/Quarter Resolution decoding (don't forget to click Set Us Default).įor UHD you most likely will need half resolution and then you will be watching HD version of your UHD file at few x less CPU power needed. Once added set "Prefer" to make sure this decoder is used as default one for Cineform decoding. Go to View/Options, "External Filters", Add Filter and find GoPro-Cineform Decoder-2. Anything based on ffmpeg inside, like VLC is not good as their decoder is not very fast. You need to have installed Cineform codec ( ) as it's the fastest decoder (maybe you have it already installed). It's matter of proper player and decoding chain. HD should work perfectly with Cineform for your CPU. YT works because it's h264 which gets decoded by your GPU (well, special part of it made just to decode some video formats). It takes several hours to upload a 4 gb video to YT, so doing that just to check to see if everything is ok with the video's content before I publish it is not practical. But I know they are not choppy because when I upload it it to YT, it's smooth.
When I try to preview it in any video player I have, windows media player, VLC, KM player or All player, there are ones that can play the video but play it choppy, others can't because of the video codec. I use the AVI gopro cineform YUV-10 bit for rendering because I love the quality. Jim Figurski wrote:I am just finishing up my first youtube video using davinci resolve 14.2.0.012.
