I am having an ongoing problem with this. I create an mpeg file out of a video photo montage and it looks fine on the preview and then once I render the video the titles flicker up and down like mad no matter what I use to play back the thing be it my tv or my computer. Am frustrated. Here are the properties of the video

Any ideas what I can do differently to possibly stop this?

Thanks

I am not absolutely clear what you mean by a "video photo montage" -- do you mean just a photo slideshow which you convert to video? Or do you mean a mixture of both video clips and photos, which you are re-rendering into a single video?

If the former, you might want to try setting it to be Frame Based (which suits photos down to the ground and should not otherwise flicker), rather than Lower Field First. Mind you, I don't otherwise know what is causing the problem, and I have produced slideshow videos without any flicker in the titles... And in fact, I just quickly threw together a few photos, added a title to the beginning and end, and rendered it using exactly the same properties as yours, including Lower Field First, and the titles in the final video remained rock solid.

Thanks Ken,

Yes it's a simple slide show from still photos. I figured out what is going wrong and it has to do with my work flow. I make a lot of these photo shows with pan and zoom for a local funeral home to present as a video tribute at the service. Most of the time everything is OK but every once in a while this flicker thing happens with project's titles.

Here is what happens and why. I insert all the photos into the time line at six second duration and adjust pan and zoom and insert cross fade transitions. I use six seconds with a one second transition because it makes a pleasant transition and a small video only file which renders quickly. Then I build the ending with the titles. I do it like this because sometime I get the photos one day and it takes a day or two for the family to decide on what music they want and bring it to me. And then the service is the following day. Miracles in production time are often expected and funeral services never wait. As a result the final duration of the video is determined not by the number of photos but by the duration of the audio track. So I had been building the video only file ahead of time including the titles and rendering it to an MPEG file called video only. I then start a new final project where I start with the audio and insert my already rendered video only clip and stretch it to fit the audio. Well if the video only clip ends up 6 minutes long, and the total audio track is 10 minutes I stretch the video to match the audio since timing isn't critical in this type of project. This is what is causing the titles to flicker, slowing down the video like this by stretching it's time. The photos do not flicker, only the titles. And not bad enough every time to annoy, only every now and then like this project I am working on now. I am not sure why this happens but I re rendered the video portion of the project without the titles and added them after stretching the video in the next step. where I added the audio so it wasn't necessary to stretch the titles and the problem was solved. Since I make so many of these tributes I am constantly trying to refine the work flow to save time. I had designed this work flow to accommodate the circumstances but it ended up with this glitch, now solved.
Sorry for the long winded explanation but since I asked for help I figured I owed it to you and the forum to explain the solution. The bottom line is if you create a slideshow like this and subsequently change it's playback speed and thusly the duration in order to change or add audio to it you can expect these results with your titles. I suspect it's not just a slideshow but any video with titles embedded into it that you change the speed of. Here is the actual title portion of my video tribute which prompted this thread showing the before and after result of slowing down a title. http://www.youtube.com/watch?v=R7OFS-S5MYQ

I was getting a little stressed as the service is this afternoon and I didn't want to present that amateurish nonsense. Ah the devil is always in the detail!

Nice that you figured it out.
