720p50 playback issues (playing too fast or not framed correctly)
Hello,
Apologies if this is already covered but I’m looked through the forum and couldn’t find anything about it.
Having a free strange playback issue in 8.0.1. I have a project that is 960×720 25fps, shot in DVCProHD Pal. I create the timeline and play it back through the HD1080Psf25 playback setting and it looks great on the grading and client monitors, but it’s showing a 720p image in the middle of the 1080 field, so there is a black bar all the way around.
In order to fill the entire monitor with the 720p image, I switch the playback to “720p50” since there doesn’t seem to be a 720p25 playback option.
At this point the image scaled properly but Da Vinci tries to play back the 25fps footage at 50fps, so double speed.
I can change the timeline playback setting to 25fps, but then when I go play the timeline I get a warning (“You are playing the clip at a non-native speed”) and the audio is now playing at 1/2 speed as well, so it’s out of sync.
Seems like there is a setting somewhere in there that I’m missing, I just can’t for the life of me find it.
thanks,

You want to upscale the image to full HD in the Import settings tab.

I am experiencing similar issues with dv material and 720p30 stuff, playback seems to be ok, but I’m getting weird aspect ratio issues. I’ll see if just outputting a full hd version helps.

It’s a feature for a client so I don’t know how they’d feel about upscaling the whole thing unless we went to something like a teranex or a genum, but on future jobs I might pitch something like that.
Under “Input Scaling” (is that what you mean by import settings?) I’ve tried all 4 settings and none of them seem to work with “HD 1080” selected in video monitoring. It just affects how the 720 is scaled with it’s 720 box on the 1080 monitor, but doesn’t scale it up to 1080.
What’s weird is there is no 720p25 option in the video monitoring format, and Resolve seems to treat 720p50 (which should be referring to 720i50, I would think) as being 50 reel frames per second and playing back at that rate.
Very strange.

Hi Charles,
Resolve/Decklink currently only supports 720P/50, 720P/59.94 and 720P/60. These are 50fps and 60fps.
We do not support the 720P/24, 720P/25 or 720P/30 on the Resolve/Mac. On Linux with the NVIDIA SDI card, these frame rates are supported.

Rohit what are your recommended work arounds for those formats?

Up sample to the 1080p/24,25,30 formats in the config page and then you can always drop it back to 720p while rendering.
