    It’s an interlacing problem. Mark is right, check your field order. However, this can originate all the way back to the beginning, when you transcoded the footage, your settings may not be correct. There are tons of threads on here about interlacing issues, have a gander at them. Also, you can try deinterlacing the final QT that you exported. You will lose a little quality by making another transcode step, but might be a faster fix than restarting from the beginning.
    Also, on a side note, you shouldn’t name your thread with Hi Guys. Be descriptive so people know what it’s about without reading your post.
    Let us know what you find, good luck.

    It’s the HDMI. I run audio and video separately, so I don’t know if the above comment will work, it might give it a shot. One way to fix this is to offset your video feed by a few frames. When I play video to my client viewing HDTV I have to offset it by 5 frames to have the audio playing separately through a mixer and monitors to be in sync with the HDTV. It’s not perfect, but it’s pretty darn close.
    Go to System Settings, then Playback Control, then Frame Offset. You’ll have to play with it to find the right number of frames.

    The color temp looks like it’s close tho, look at the white wall and gray jacket. It looks more like the JVC camera was underexposed. Try bringing the exposure levels closer, then try the three way CC to bring them together. RGB balance might help a little too.

    December 5, 2011 at 4:29 pm in reply to: Audio Sync Problem

    Hi Felix,
    Make sure the audio that you are receiving are the same specs as the mp3. For instance, if you started your edit with the mp3, then your sequence settings should be exactly the same as the mp3, ie. 48khz 24bit. The new track, is it a wav or aiff? Make sure this file is exactly the same as well. The audio sync sliding out of sync by the end is a symptom of differing audio specs.
    Also, don’t bother with Soundtrack Pro. You can sync it up just fine in FCP. The extra step into SP is unnecessary.

    Not sure if this would make a difference, but have you tried exporting a QT self contained instead? This way, there is no question for Compressor for video and audio start?

    At 1920×1080 at 60i, ProRes 422 needs 145 MB/s, while HQ needs 220 MB/s. Your external FW800 should be able to handle 145 MB/s. Codecs and speed is dependent on the number of video streams (tracks) that you are using in your timeline.
    Make sure the number of video tracks in your timeline is not overly excessive. The minimum number of tracks as possible. Same for audio, but not as important. Also check to see if you are feeding any video out to an external monitor? If so, turn it off and see if this helps.
    Don’t run extra windows like scopes or audio mixer. Are you rendering heavy effects and filters and CC? This ups your need for speed.
    Keep everything on your external, except your project file. Check your connections.
    Also how much RAM do you have? Maybe RAM is going bad? You can download free software that will check the health of your RAM. Speaking of which, check the health of your external. Try a different FW800 cable?
    I had this issue at one point cutting at 422 HQ. Other than upgrading my hardware, I was able to get it to work a little better by doing all of the above. I still had skips and dropped frames here and there, but it helped alot to finish the project. I also moved all of my audio files to another drive. At the time I had 2 striped internal SATA drives in RAID 5. Internal software based RAIDs generally don’t work, there is an inherent bottleneck. Maybe try a new drive, it could be the external itself.
    In the end, the real fix for me was to build an 8 TB DIY RAID 5 array connected with a hardware based RocketRaid card and mini SAS cables. This fixed everything, and at 3/4 full I’m still sustaining numerous full quality streams of ProRes 422 HQ, generally around 500-600 MB/s Read and Write. It wasn’t cheap, about $2k, but cheaper than already built arrays. For me, it was a speed / bottleneck issue. But you have to go through the work and time to narrow it down. Good luck.

    November 30, 2011 at 5:21 pm in reply to: FCP 7 render error: dashed line on hightlights

    Huh, so my hunch was right. I generally don’t use that effect, I’ve never really had success with it. Caused more problems than I wanted. You can try the Sharpen under Effects/Quicktime instead?
    Is the image too soft or something, is that why you need to sharpen? I generally don’t do it unless it’s really really bad. Or if you are trying to sharpen something very specific, you could do a composite and garbage matte just the object you need to sharpen? I can’t imagine why you would want to sharpen the blown out horizon…

    November 30, 2011 at 5:11 pm in reply to: Render error: insufficient disk space

    Rafael is right. The general rule of thumb is to always keep about 25% free on all HDDs, this includes your systems disk (computer HDD) and your scratch disk (external HDD). Once you start go past 25% of space the HDD tends to slow down.

    That looks like it could be from the sharpen effect that you added. I’m guessing that since you shot indoors, facing windows to the outside, that those “highlights” are actually not highlights, they are completely blown out sections of the image because you have to open up in order to expose correctly indoors, and the outside doesn’t get enough exposure. Because of this, coupled with the 60D’s inability to give you alot of data in your highlights and shadows, when you color correct, you are hitting your ceiling, and it’s starting to make stuff up now.
    I’ve seen similar problems like this before, but I can’t remember what camera, settings, etc. But I do realize that it’s a grading/effects issue where your footage doesn’t have enough data in it for you to push it this far.
    I would tick off one effect and render. If it’s still there, try another effect. Do this until you find the culprit. I have a feeling it could be the sharpen effect.
    I just looked again and want to be sure we are talking about the same thing: you mean the dashed lines outside on the horizon right? Not that weird white dashes at the hands of the subject (looks like part of the animation)?

  • Dave is probably right. Would like to hear if this fixes it.
