Extracting from mkv then merging hecv without losing quality

[Anonymous138]

Hi,

I've done a ton of google searches and experimented with several programs and after hours of searching, I can't seem to find a clear answer, so I was hoping I could get some help. Basically, I have an HD mkv file that I need to import into Adobe Premiere to edit, but Premiere doesn't accept MKV files. So I need to convert it to another format.

So when I try programs like mkvtoolnix or gmkvextract, it seems to only let me extract the audio and video and doesn't let me merge then in one step. The Audio is AC-3 and the video is HEVC (h.265). Since it's an h.265, I'd like to keep it that way and not have to go back to h.264.

What exactly do I need to do to extract the mkv file, then (without losing quality) keep it as hevc with audio?

Thanks!

Not having the slightest clue what container formats Adobe Premier supports.

Try AnotherGUI. Put ffmpeg exe in the same folder. Create a preset like this:

-report -i "<FullSourceFileName>" -y -threads 1 -vcodec copy -acodec copy -sn "<OutputPath><OutputFileName>.mp4"

Drag and drop the MKV onto AnotherGUI and click "Go". If there's an error, check the ffmpeg log file for info. I think it'll be saved to the same folder as ffmpeg.exe
If you need another output container, change the MP4 extension to something else (as long as it supports HEVC and AC3).

Doesn't Premier let you import the video and audio individually? (I've barely used it myself)

Hi,
Thank you for your reply! And yes, while premiere will let you important video and audio individually, I need to do this for about 20 files. I was thinking of just deleting the mkv versions so I don't have 2 versions on my hard drive.

You're welcome.

I thought I'd mention Box4 might be worth a look too.
