For the best results please follow these steps when exporting from DaVinci Resolve:
Click on the rocket ship icon at the bottom of the screen labeled “Deliver.”
In the Render Settings on the left, select 'Custom Export.'
All the default settings should be optimal except for the following...
Set the Format to 'MP4' and the Codec to 'H.265' or 'H.264' depending on your needs:
Only use H.264 if you need your exported file to be compatible with older devices. MediaZilla accepts both H.265 and H.264, and provides an H.264 version for download in addition to the original file you upload.
H.265 is a newer and more efficient codec. The file size of the H.265 version will be smaller and have better quality than the H.264 version.
For 4K output, always use H.265.
The resolution and frame rate should be set to the same as your timeline, which should be the same as your footage.
Select “Chapters from markers” below the frame rate, then choose the timeline marker color you used for all your chapter markers. Ignore if you do not want to embed chapters in your video file.
Set Quality to 'High' or 'Medium' depending on your needs:
'High' uses a bitrate that is more than sufficient without any noticeable visual quality loss compared to the original. Recommended for most content.
'Medium' quality is also acceptable with only minor visual quality loss, and creates a file that is approximately 30% smaller compared to High quality. Medium is recommended for those wanting to be more economical with their file size while having minimal impact to quality. Typically best for long-form content.
'Best' quality uses an extremely high bitrate that is completely unnecessary for nearly all use cases. There is no noticeable visual quality difference between 'Best' and 'High'.
If you are using the older 'H.264' codec, be sure to disable 'Frame reordering', as using this will create a file with a variable frame rate which is not compatible with our accelerated transcoding process. There are no issues with using Frame reordering and the H.265 codec, and should be enabled for a more efficient compression.
Click 'Add to Render Queue' and proceed with the export.
Important: Always be sure your output resolution has even values for width and height. Many codecs do not support odd resolution values and the results could be undesirable.
