dissolve problem in 24P sequence

[Michael Sacci]

[alan] “I had to change my video playback to AJA Kona 1080i 29.97 in order for the card to pay it back on my studio monitor.”
This is not something that the card needed but the TV needed. Unless your TV supports 24P the card has to add the pull down to make it 29.97.

We work in 24P all the time and have no problem with dissolves, are you making sure the dissolve is rendered, if the timeline is orange (or even green) RT drops frames and quality to pay the footage without rendering. But if you want to evaluate quality you need to render the dissolve.

No our monitor is older and does not support 24P and I understand the pulldown issue for playback. Plus, I have been making sure the dissolves are rendered. But still we are getting a very stuttered dissolve, so something’s not right either in the playback setting, sequence, or Kona. I’ve made sure to match the sequence setting exactly to the XD Cam footage. Could it possibly be something to do with the video playback settings being 1080i 29.97 conflicting with the sequence settings of 1080p 24?

its not a kona problem, – purge your render files then re- render, making sure the quality of the renderer is set to highest quality, and the EVERYTHING under the render menu is actually being rendered- this is not the default setting for the render engine and needs to be set correctly.

your problem sounds as if your computer does not think it needs to render the transition since the system says it does not need too.

Let me throw this one at you Gary. I did what you recommended. checked the render control and the setting were indeed set to highest both in sequence and user preferences. I trahsed the reder files and re-rendered. Interesting! The video to video dissolves looked much smoother, but the fade from “slug” black to video still was very stuttery. What’s your take on that?

[Michael Sacci]

is there a shift fields on the slug. Don’t know if you are using FCP6 but I notice this was added to my FCP5 projects when opened in 6. It was only added to slugs.

[Alan]

Hmm. I think you’re on to something. The slug generated is lower field and my timeline is 24P. Yet when I took away the slug and just added a dissolve up, I still get the stutters?
