In the comments on our post Avid Still Have Serious Problems With Video In Pro Tools 11 Richard asked…
Can someone explain how to convert to Avid DNxHD? I have downloaded MPEG Streamclip and the DNxHD codec. I don’t really understand how to connect the two. Many thanks!
There are several ways to do this, but before you start, make sure you have downloaded and installed both MPEG Streamclip and the Avid DNxHD Codecs.
Open MPEG StreamClip and either drag the video you want to transcode onto the empty window or use the Open Files option in the File menu.
Choose Export to QuickTime from the file menu…
Select the AVID DNxHD Codec from the Compression drop down menu…
Thanks to Sounddroid for pointing out this crucial step which I missed that would explain my huge file size. Click on the Options button and choose the most appropriate setting for you. You are choosing from 1080 or 720, the frame rate, and level of compression. Sounddroid suggests…
People in post will generally want to use 1080p / 24 / 36Mbit / 8-bit, or 1080p / 23.98 / 36Mbit / 8-bit, depending on the project settings.
That would make sense for film work but for TV post you are likely to want either 25/50 for PAL or 23.976/59.94 for NTSC countries.
Then check the rest of the settings. I tend to leave the Frame Size on the (unscaled) setting so the movie isn’t resized. The other thing I also do is to deselect Interlaced Scaling and select Deinterlace Video especially as I am displaying the video on an LCD screen. I have got so fed up with seeing interlacing artifacts that I end to doing it every time now to be safe.
Once you are happy with the settings, click on the Make Movie button and determine where on your system you want to save the transcoded video and hit Save.
Now wait for MPEG Streamclip to transcode the video and then you are ready to import the Avid DNxHD version into Pro Tools in the normal way. Job done.
Petr Styblo asked…
Hi guys ! Did someone find out how to setup default this codec, that we don’t have to choose it every time from menu ?
Petr, yes you can and here is how. First make sure you have all the settings just the way you want them.
Click on the Presets button, and then from the Presets window select New.
MPEG Streamclip asks if you want to create a new preset, click the Yes button.
Next give the preset a name and click OK.
Now you can click on Presets, select the preset you want from the drop down menu, and click on the Load button and all the settings are recalled for that preset including the Options set for the Avid DNxHD codec.
