App to play 2k QTs through BMD hardware?

PostWed Aug 15, 2018 9:49 am

Hi
It seems the only way I can play QT files [ProRes, DNxHR, H264 codecs] through my BMD Ultrastudio 4K on a Mac is by using the Media Express app. This works fine for HD, but won't accept 2K or larger files.
Is there any media player app that will do this?
Thanks
Nigel

MediaExpress should play any format which is supported by card.
Resolve, Switch Pro, ffmpeg, Scratch Play Pro, CORTEX DIT....

Ultrastudio 4K can play only 2K at 23.976p, 24p, 25p. Is this what you are trying to play?

Yes, I'm trying to play 25p.
Could the raster size be the problem?
My QTs are 1998 x 1080 [Flat] and 2048 x 858 [Scope]
Thanks

This is not going to work.
They have to be 2K with blanking.
With apps like Scratch Play or Resolve you can have them native frame size and play as final 2K output. MediaExpress requires exact/supported frame sizes (it has no "frame composting", eg. black padding capabilities).

Ah thanks, I see.
Are there really no apps [like QT Player, VLC, or MPEG Streamclip that will work with these files and BMD?
If not, what raster size would ME accept for 2k Flat and Scope - 2048 x 1152 with relevant letterboxing/black padding?

2K- 2048x1080.

Your best bet is Scratch Play Pro (should be good choice), Resolve, CORTEX DIT (free). Those should be reliable and give you color accurate, 10bit preview.

There are no "simple" and reliable players with BM support (specially for what you asked for).

If you want just some playback you may use MediaPlayer Classic HC (with madVR renderer) with 2nd full screen display/TV over HDMI out of GPU. When configured correctly this can actually be also an accurate preview.
