I had a Premiere Pro CS 5.5 license and all the videos were importing just fine. To recap, if you edit your clips in Premiere, then export using ProRes or DNxHR, you will not really lose any quality at all but will end up with larger files that are easier to edit basically.I just installed Premiere Pro CC from Premiere Pro CS 5.5 and now every time I try to import an mp4 from my Galaxy S10, it says "The file has an unsupported compression type." Do I have to install something extra? Note that I selected DNxHR as the Export format and it automatically chose a preset that matched my UHD 24p sequence. So when exporting/transcoding, make sure the Source and Output settings both match with 3840x2160, 1.0 pixel aspect, 23.976fps as shown below. When looking at Sequence Settings and Export settings, you want to look for UHD at 3840x2160 to match your camera recording, as what they call 4K is actually a higher resolution of 4096x2160 which is more of the Cinema version of 4K. Editing will be much more responsive and such, but of course editing machine must have large, fast storage to accommodate those larger files. Please note that when you transcode the footage, the resulting files might be 4x-8x larger than original clips.The up-side is that those clips will be much easier to edit since they are less-compressed, meaning the computer does much less work at "unpacking" each frame for display. Use Media Browser in Premiere for the actual import. Do not "pick and choose" video clips - copy it ALL since there are other folders/metadata that may be critical to recovering all footage and audio in Premiere. In any case, KEEP the original files intact for safety! This means create a New Folder on your hard drive, and copy ENTIRE contents of SD card to that folder. mxf file, or the GoPro Cineform codec is also excellent as a. On PC, try DNxHR which is an Avid codec delivered as an. For Mac, Apple ProRes was already mentioned.
So what you want is a high-quality, near-lossless intermediate codec.
mp4, as H.264 is a lossy codec and you don't want to transcode to that for editing. Also, forget any ideas of delivering a cut version as. But you don't want an "uncompressed" format, which makes very large files for HD and gargantuan files for 4K, with NO QUALITY BENEFIT since the original footage was already quite compressed - uncompressing it does not improve quality one bit. Why not give editor all the material? You won't be able to chop up the files and still deliver the original XAVC codec, so you will be re-encoding (transcoding) the material to accomplish that.
