Hello. I am shooting in DLOG-M on the DJI Mavic Pro 2. I have finished my video, after exporting it I have realized that the video has lost a lot of quality. Ive done a good amount of research on my export settings and its still wrong somewhere so I'm hoping someone can help. I will list the current clip/sequence and export settings; Source: 3840x2160, 23.976fps, 5 minutes 18 seconds. Output: Format=HEVC 3840x2160, 23.976fps, Hardware Encoding, CBR target bitrate 100mbps, AAC, 320kbps, Render at maximum depth check, Tier:High, Quality:Highest(slowest), Use Maximum render quality check, Frame Sampling. The estimated file size is 4002MB, the actual export size is 1.29GB. There is clear loss of quality. The last thing I should include is I'm working on a ASUS laptop: Intel core I7-8750H, CPU @ 2.20GHz, Ram 8GB, 7.85 Usable. Windows 10. Graphics card: NVIDIA GeForce GTX 1050

Just use the Match Source - High Bitrate preset and don't customize anything.

 

Also, consider transcoding all of your source footage to a COCEC that is good for editing.  I recommend Apple ProRes 422 LT if it's for YouTube or Apple ProRes 422 HQ for Broadcast or Cable.  Work in a Timeline set to match QuickTime ProRes for Previews.  If you export to ProRes for an edited master, you'll take advantage of Premiere Pro's Smart Rendering for really fast exports.  You'll finish with encoding your ProRes edited master to HEVC (or any other delivery format that you may need).

 

Yes, your ProRes files will be large (probably 1GB per minute give or take), but CODECs that are good for editing are just that.

I've had similar issues except my export is choppy compared to the original video. The raw 4K HEVC footage looks stunning in VLC media player but when I export in Premiere (in H.265 or H.264  - tried both), convert the codec, or ANYTHING then the footage becomes laggy/skippy like it's at 5fps. Exporting as "Match Source  - High Bitrate" doesn't solve the issue, in fact I have no idea what does solve it but I've tried it all. Also, it's not a playback issue on my computer becuase I've uploaded various versions to youtube with various export settings and watched on different devices to confirm it is just a choppy video  - and as I mentioned the raw 4k HEVC footage plays flawlessly on VLC media player  - but not after export or simple codec conversion.

Laggy playback after transcoding camera original footage to a CODEC that's good for editing (ProRes, DNxHD, Cineform) is almost always a result of the storage media not being able to sustain the data transfer rate required of the clip.

 

Blackmagic Disk Speed Test is a great utility to test storage media, but any benchmaking app that can measure sustained read times will do.  You can compare those results to the Get Properties option in   Premiere Pro.  The desktop application MediaInfo is very popular for getting a movie files's data rate.  If you happen to have QuickTime Player. Data Rate is displayed in the Inspector window.
