Thanks for the response Floh. I assumed it wasn’t working properly because of a wrong codec clip I just couldn’t find it, and this explains it!

Another quick question, if you export a ProRes timeline via quicktime (not self contained) in the export window, does this re-encode all the ProRes video to ProRes (meaning a loss in quality)?

edit:
So when you say Quicktime “displays” the first codec it finds in the file, only the black clip is a different codec and the codec actually switches to ProRes in the Quicktime file? I wasn’t aware that you could have multiple codecs in one Quicktime file.

Thanks,

I find it interesting that Media 100 AVCHD import “knows” what the footage is, but a manual import is different. I only noticed it because I used the AVCHD to import about 100 clips and had to shut the machine down half-way through so I canceled the import. Clipwrap had finished re-wrapping, so I was later on able manually import the last half of clips – and the colors were different. It drove me crazy until I discovered re-importing the same clip using AVCHD import from the source gave me the right coloured video.

Thanks for your response Floh.

Yeah if I import via clipwrap, the clips look different than when I manually import the clips after just re-wrapping the clips to quicktime. Same codec, same media standard. Also, when I look at the clips in list view, the Source Media File Size reports the clips at slightly different sizes, which tells me something different is happening to the clips. Gonna try some more tests.

I forgot to mention we are running M100 Suite v1.5.

Also I am aware that cleaning all clip tails will help solve my second problem, but it won’t stop the transitions from disappearing. For some reason I am a little afraid of the clean program button for fear of strange things happening.

I will try. It seems (in this case) the clips that M100 isn’t liking are over 1 minute long. Although there are a couple that are over a minute long that it had no trouble with. The smallest one is around 500 MB – we don’t have that much room on our server at the moment. I will see if I can clear some room.

I will also add that we have received media from an XDCAM EX3 on a hard drive and some of the clips were over 15 mins. There were over 100 clips and there were no problems at all.

Thanks Floh,

I finally got it working. The problem seemed to occur with manually rendering the slideshow. If I imported all the slides, put the transitions and moves in, then rendered manually from the “File – Render – Slideshows” the images would render at half res upon building. I even went in and checked the movie files it was rendering…all half res (like single fields doubled..yuck). However, if I took the same slideshow – instead of hitting render after applying the transitions and moves – and just selected “build DVD Disc” (er build anything really), the pictures came out fantastic, after auto rendering before the build. This kinda sucks, cause you have to go through the 45 mins (err whatever depending on the size of the slideshow) every time you want to build. But this far outweighs the crappy quality of images you get from rendering slideshows manually ahead of time.

Is this a bug, or am I missing something when I want to manually render a slideshow?

Try it out…I have several times, I want to see if others get the same results.

I believe this is the problem I am experienceing, except all of my images are moving, so I-frames can’t be the culprit of the “Shimmering” photos. It must be something Encore is doing, because every time I restart and import the same pictures, it happens in different places…sometimes on ALL of the photos, and sometimes even just during the cross dissolve.

I looked at the video files encore is making, and they are “Shimmering” as well…so it must happening during the rendering.

The images are all jpegs. None of them bigger than 2500 x 2200. It doesn’t happen randomly every time the slideshow is played, however, if you change the order of the slides, then different slides will be played at half res.

I started all over again, and just quickly imported all the images and applied a cross dissolve to them, as well as random motion. All of the images appear to be half res now (by half res I mean they appear to be single field). Not sure what is going on.

Also, how do you force a slideshow to unrender? When I make a change (ie. globally change the time of the transition) the clips all stay green. I can unrender them by applying a different transition to the wole show…but when I change it back to cross dissolve (the one I had rendered it with) they all go back green and don’t re-render.

I am not exactly sure, but my guess would be to disable the whole “drop frames to maintain data rate”. It is probably dropping video frames while the audio continues to play.
