    Posted by Darren Macnally on August 31, 2013 at 12:32 pm

    Hi there, I’m having a problem with the preview for Sony Vegas 12.

    Now I know there are several threads about this, and believe me I’ve been searching for a few days now to find a fix.

    My problem is a little bit different. first off, my computer is good, here is the spec of it:

    -AMD FX-8350 4.00GHz Eight-Core AM3+ 8MB L2 Cache & Turbo Core Technology
    -2TB SATA-III 6.0Gb/s 64M Cache 7200RPM Hard Drive
    -16GB DDR3/1600mhz Dual Channel (Kingston HyperX Blu w/Heat Spreader)
    -AMD Radeon HD 7970 3GB 16X PCIe 3.0 Video card
    -Windows 8
    -ASUS M5A97 V2 AMD 970 Chipset, ATX mainboard w/4RAM slots, 7.1 Audio ect ect.

    The files im working with are gameplay footage recorded from DXTory.
    They are recorded in .avi format and each weigh in at about 8GB. Usually like a GB a minute.

    The preview for these clips on the timeline is extremely stuttery and has terrible framerate. I have tried varying the amount of dynamic ram from 0, to 8GB and no difference. no difference for different preview window sizes either.

    When I load a .wmv clip it runs fine, although the wmv clips I have are about 200mb so I dunno if its a file type issue or what.

    The weird thing is, I had a PC with about half the power working the exact same files before about a month ago. Using the DXTory avi files that has same file size and everything without problems.

    Any ideas on a fix for this? Preferably without just converting everything before editing as that will double my workflow time having to essentially convert every file I record.

    Thanks in advance.

    Hmmm, do a CODEC check.

    Like what do you mean? In recording with the lagarith lossless codec.

    The weird thing like I said is my last machine could handle all this same stuff fine.

    Footage recorded from Dxtroy is sometimes a
    problematic format to deal with, because its not
    a format ideal for editing.
    However double check that you have everything installed
    on your previous computer, installed on this new one, since
    you mentioned it could handle it without problems.
    Not sure what other solution i can offer.

    I feel I have everything my older computer had except this new computer is windows 8.

    I guess I’ll just have to go the video conversion route. Any reccomendations on what’s the best converter to use?

    It’s very important to me that I don’t lose any visible quality in the conversion.

    Super is a very good converter that is free.
    It handles anything you throw at it.

    I won’t use Windows 8 until I absolutely must, but I suspect that the Codecs installed by Windows 8 are different from the ones installed by Windows 7.

    On the issue of codecs – NEVER install a codec pack on an editing PC. You risk replacing otherwise fine codecs installed by Vegas with really inferior ones.

    On the Dynamic RAM – this RAM is only used when you use Shift-B to render a region to RAM. If you never use Shift-B renders you still need some preview RAM. A few years ago someone, and I don’t recall who, did some rendering tests with diferent amounts of Preview RAM and discovered that no preview RAM took longer to render than with some Preview RAM. 1Gb seems to be the sweet spot.

    Okay so I tried the Super video converter that was mentioned above.
    Even with Top Quality and High Quality settings, with no resolution change and the highest bitrate option there is a still a visible drop in quality of the converted video.

    Can someone reccomend, or perhaps show me the settings of the Super Converter that will not drop the quality below 95% of the original?

    Or can someone reccomend a video converter that doesn’t drop quality and will convert a .avi to a .wmv or .mp4 file type.

    Much appreciated. The converter “Super” wasn’t ideal for me anyway because it requires you to click a few options after each conversion and I could have 4-5 at a time overnight and can’t select the option.

    Alternativly if there is a solution to the preview problem that would be even better! Don’t give up on me yet guys

    First – NO conversion program or re-encoding process is loss-free. Some get close, but there is always a quality hit. I don’t care what the marketing people say, lossless recompression is impossible. Good codecs can recompress with no observable losses, but there is data loss.

    I have never heard of Dxtory, but looking at the specs on the website, it looks like you can select the encoding codec. Try Lagarith.

    Is there no video converter that just doesn’t do a compression?

    I am using the lagarith lossless codec while recording. It’s great, my footage comes out looking just as it did at recording. It creates it in a .avi file. However, Sony Vegas’ preview feature doesnt work with this for me for some reason. So I want to convert the .avi to a .mp4 or something that the preview does work with.

    That’s the dilema. Ideally, I wouldnt need a conversion, like I said before, My older PC (which was 2-3 times less powerful) took the .avi file in Sony Vegas no problems.

    I need to correct what I said earlier – yes you can re-encode a file in a lossless codec, but you pretty much have to be doing nothing to the video in the process. No frame rate change, no bitrate change, no color correction, and no editing. any of these requires a recompress. I meant above that any recompression of the file will have data loss. The Lagarith codec is pretty good for lossless encoding.

    But the basic question remains unanswered. Upgrading Vegas should not take away any formats that once worked in an earlier version.
