Hi guys,
Can you help me with the render settings on VP17?

I want the best result because I need burn my project on a Blu-Ray disk without loosing the quality. Thank you in advance!!!!

With 2,7K you are bound to lose quality.
BD supports only 2K and 4K (with HEVC).

The question is did you REALLY record in 60p, or in NTShitC in 59,940p.

Your options are either to downscale it to 2K, or upscale it to 4K to HEVC.
But your best bet is to crop to 2K, of course if your frame composition allows for that, if you have uneeded background.

As for bitrate, I don't remember if BD supports compressed audio of GP, but you can uncompress it to 16/48 LPCM. Max video bitrate is 40Mbps, so set to standard 36Mbps.

And you're good to go.

But next time stick with proper natural number framerate of 25, or 50 fps, makes life much easier.

The good news is that the GoPro 2K7 is progressive. Simply render out to a standard MainConcept MPEG2 BD 1280x720P template. (video stream). Render out the audio as ac3pro or similar. Add files to DVDA and it should be accepted. Let your TV do the upscaling to 1920x1080. It will look fine. Never fails in PAL land.

BD standards are 1280x720p or 1920x1080i 50fps in PAL or 59.97 in NTSC land.
Make sure your timeline properties match your clips/files.

Best of luck.

Nah. Render to full HD instead of regular HD.

BS is 25 frames per second or 50 fields per second. If it's natively progressive, then keep it that way.

Crop, or resize to 1080p.

Having rendered or cropped to full HD how do you burn your BD so as to remain progressive?

Am somewhat puzzled as my understanding is that BD accepts 1080i or 720p.
1080p is not a BD standard in 60 or 50 fps. Maybe 1080p 25fps but not so good for fast action. Not a format I have used.

Enlighten please?

BD supports not the progressive FHD:

The trick is in HEVC.
