My exported video looks like it had too much time in the H.264 department.

edited November 2017 in Express Support

So problem is that after I've exported my video, it desyncs the audio, the compression is out of the window, and it is just generally bad. This is a gaming video, so there could be problems with the fps and such, but in that little video where you have a preview of what is happening of what you've edited, it looks completly fine. No desyncs with audio, the compression is good (had it at 95Mbps btw(recorded with Shadowplay)) and nothing looks bad at all, but the exporting part. HOO boy! It is shit. So what could I do wrong?

My export settings are:

Widt: 1920

Height: 1080

Scale Mode: Keep Aspect Ratio (can't edit)

Frame Rate: 60 (video is at 60)

Apect Ratio: Square Pixels (1.0)

Profile: Main

Level: 5.0 (if I have it at 4.0, it won't allow me to render)

Endcoding: Constant Bitrate

Bitrate: 95.906

Audio Bitrate is at 448 Kbps.

So did I do something wrong? Is there something I should channge?


Edit: So I was told to downlaod a software that could give the some more information about the video, so here they are:

  • @ThaHerminatar ; I'm certainly no expert but but I suspect your gameplay footage is Variable frame rate.  I have read a lot of post that say this causes audio/video problems on export in Hitfilm.  The wizards on here usually recommend install MediaInfo and generating a report to post here to confirm this:

    download and install MediaInfo

    Copy and paste here a "Tree" report of a source file and your output file. This gives specific details on the files. 

    If it is VFR I think you have to transcode to a Hitfilm friendly type file like @Triem23 tells you about in this video:

    I hope this helps you out.

  •  @palacono Saw it, did it, video doesn't want to load, because apparently, windows doesn't support "mp4".

  • @ThaHerminatar ; Windows does support MP4 but yours, unfortunately, is going to be a little difficult to deal with. Your frame rate varies from  26.455 - 63.830 fps with a target playback rate of 60 fps. HitFilm does try to handle video with a variable frame rate but it isn't perfect and that's a pretty extreme variance. You basically have two options - You can use the NormanAVC settings for Handbrake covered in @NormanPCN 's thread: 

    Transcoding to fast decode AVC for timeline edit performance

    You mentioned using ShadowPlay but you might want to switch to OBS. Farther down in the thread I just linked to NormanPCN covers NVENC settings for OBS you can use to avoid having to do this transcoding step.

    Your other option is to convert to Cineform. You'll end up with much larger files, but HitFilm performs best with Cineform. Steps to do that are covered in my thread here:

    How to Use VirtualDub FilterMod to fix VFR issues and convert to Cineform

    Either way you'll end up with something that works and is much, much easier to deal with. Once it's done, then you can focus on output quality.

    That wide a variation in frame rate certainly does affect the quality of movement in the video. If you are getting those kinds of frame rate drops, then make sure you are using the low latency, high performance NVENC presets. Geforce experience does not give access to these settings so it is hard to know exactly what NVENC settings it is using. Probably better yet, just target 30p for your recorded video.

    OBS will always output constant frame rate but when these performance related drop outs happen, what you get are duplicated frames in the output and therefore less smooth motion in the video. The lower overhead NVENC settings can cure that situation. At least one user who contacted me for some OBS help. It cured their situation.

    @Palacono that particular sticky ain't bad, but one would be better off with Norman or Aladdinvs thread, or, dare I say it, the above linked Essential Hitfilm video which specifically collected the information in the sticky thread and some good information from Norman and Aladdin into one package. ;)

    Herminatar like Aladdin said, you're going to need to transcode. That's an insane variation. Norman can definitely help tweak initial capture settings.
