  1. Hello! I am a new / not a big techy when it comes to these type of things. I was planning on editing a video, I wanted to get my video 600 FPS for velocity / slo-mo and overall it looks very nice. By the way this is for CSGO.... So I watched a few videos, was same basic stuff but you just go into VirtualDub edit the FPS / Compression. So I add my video to VirtualDub, the preview looks great. I change video FPS to 600, then change compression to Lagarith Lossless Codec. I watched 3+ videos all highly recommend it.
    I render my video in a .AVI file, wait 7+ min... Then when its done I click on it, all it is a audio file? I add it into sony vegas I can see video there, its very very bad quality, aswell very fast forwarded. After 1+ hour of me testing things out, if I set the FPS higher then 60 the video speeds up. The video goes to 5 min to 30 seconds when set to 600 FPS... On all the videos I watched, there videos were normal time when put into sony vegas, good quality, looked great. Could I have a setting wrong or something very easy? PLease help!
    Recording software?: Fraps 60 FPS frames were not locked
    Resolution (if this helps)?: I try 1920x1080 aswell 1080x720. Quality was bad on both.
    If somebody can help me fix this I can pay you a little $$ on paypal, im not the richest person but this is very VERY annoying. Thanks, Dylan.

    So what did you expect? You recorded the video with 60 frames per second. If you change the playback speed to 600 frames per second, of course it will be played 10 times as fast: the same 60 frames which were recorded in one second will now be played in only a tenth of a second (if the playback hardware permits, or possibly frames may be skipped if not).

    You are interested in slow motion? Then you should instead reduce the frame rate. Try changing it to 30 or 15 fps to test it. If you want to go even lower, you may need some interpolation in addition, to avoid choppy playback.

    I understand what you are saying, yet I don't know if I am doing something wrong or what.

    Skip through, this guy records in 60 fps fraps. He makes the frames 600 then exports into sony vegas. No problems.

    Same with this guy.... Explain? Am I just retarded?

    Could you please edit the thread title to something more descriptive? "Please help" tells the least about your problem...

    What I did not understand is why anyone would want to record a normal gameplay at 60 fps and speed it up to 600 fps. But from the video I saw, he did not record the normal gameplay. He recorded a replay demo at a tenth of the speed at 60 fps. If this is sped up to 600 fps, you can watch it in normal gameplay speed again. And then you can edit the velocity curve in Vegas to define scenes of slow-motion which don't look choppy because the base frame rate is 600 fps.

    So the key is: Record the game at 1/10 game speed.

    Ok I feel pretty stupid. I forgot to mention I did record the gameplay at 1/10 game speed. VirtualDub isn't picking that up? Or? I don't understand why virtual dub is rendering my game in normal speed when its not. I watch the video its not normal speed... I did exact what he did.

    You play the game in 1/10 slow motion.

    FRAPS records that 1/10 slow motion playback with 60 fps.

    You open this FRAPS recording in VirtualDub (not changing the fps yet). When you play it, it should look like the 1/10 slow motion playback you recorded, because VirtualDub will play the same 60 fps FRAPS recorded.

    Now you change the fps from 60 to 600. If you play it in VirtualDub now, it should play faster than the 1/10 slow motion playback you recorded with FRAPS. Possibly not yet in real game speed though. Your hardware is probably too slow to play the video at 600 fps. Depends on your hardware. Maybe fast enough, maybe not.

    I did everything you said. Its slowed down in VirtualDub.
    Specs- Gtx 970, 8GB Ram, i7 4770k
    Thats not the issue....

    So the issue is that you have trouble with the Lagarith compression at more than 60 fps? Maybe the codec is "smarter than desired" and changes its behaviour when it has to compress a frame rate it may not be able to decompress fast enough ... how about trying e.g. the Ut codec suite instead?

    And which player did you use when you could not see a video? Maybe the VLC which does not include a Lagarith decoder and will not use any system-installed decoders?

    NO system (currently) is able to consistently, reliably play back at 600FPS. And when I say "system", I mean end-to-end with all points in between able to support it. Even if a PC is able to handle the HUGE load, no monitors other than experimental/scientific ones can do more than 120Hz (and let's not quibble about plasma's or other monitor's 480-600Hz scan/refresh rate, as that doesn't refer to the input stream framerate capability). Which means that EVERY monitor (and/or card driving it) will be dropping THE MAJORITY of frames.

    600FPS is usable as a HiSpeed cam source (or in this case, screen/frame recording) with the intention of editing & returning that framerate back down to normal levels (25, 30, 50, 60...) in some form of slomo. But previews & renders are not kept at 600FPS - they would falsely "skip".
    600 is a temporary intermediate.

    By changing the Source rate adjustment, you are speeding up or slowing down the playback. Under Frame rate conversion, you set the frame rate to whatever frame rate you want (23.976, 24, 25, 29.970, 30, etc...). This sets the actual frame rate by adding or subtracting frames.

    @ DarrellS:

    The reason was indeed to have an intermediate 600 fps game recording, to be able to define scenes with a slower speed which will eventually be rendered as slow-motion scenes with fluid movement, and the rest will be reduced to normal speed with a sane frame rate in Vegas while rendering out to a final format.
