Exported video not following settings for fps?

I rendered a 30fps video in hitfilm express, but the rendered video looks like it's 10fps... any suggestions?

 

(Ask more questions if needed)

  • Also, when i was editing this video, dragging clips onto the timeline or just moving clips around, would freeze the program for about 3 minutes, and when i zoom in or zoom out, or scrub through the timeline, it would also take about 3 minutes to show the audio levels and preview frames on the clip, and when it's loading those, the program is also frozen.

    Well. I'm sorry to say there's very little useful information in your post. Here comes the questions. 

    First, system specs. CPU, GPU, OS, RAM and storage? Are your GPU drivers current? What Antivirus are you running? Is it a Dell or Alienware? 

    Secondly are you doing pure animation or are you starting with video? If so, what is the format, codec, bit rate and frame rate of the videos? 

    For checking systems specs and media specs, refer to this video, starting at about 17 minutes. There's a good chance you'll be referred back to this video later. You'll need to generate a Tree View in MediaInfo (download link in video description) to paste here.

    Are your project frame rate and the frame rates of any Composite Shots you've created 30fps, and are you exporting at 30 fps?

    Video:

    Shot on a 1080p30 camcorder, with a bitrate of 25000Kbps, about 1 hour long

    h.264

    Rendering settings:

    MP4, 25000Kbps, 1080p, 30fps.

    All composite shots are in 30fps.

  • "looks like it's 10fps" or is?

    Get yourself a copy of MediaInfo: https://mediaarea.net/en/MediaInfo/Download  and see what speed it's actually rendered at to start with.

  • No, the info claims it's 30fps, but when i compare the original video to this one, it's like a slide show quickly

  • Cut'n'paste the MediaInfo from the two versions. I'm wondering if your export version is actually the 25000Kbps you say it should be.

    Could be out by a factor of 10 as a simple typo, which would make a difference in playback ability for your PC.

  • Well, it's showing the final video as having a bitrate of 25205Kbps, which should be correct(close).

  • Cut'n'paste the MediaInfo from the two versions.  There is other useful info in there. If it was as easy as you looking at a single line you'd have solved it by now. :)

    Seriously, CUT AND PASTE the mediainfo report That will have  A LOT of information that could help us figure out the issue. That's why I asked for it in the first place.

    Right now you've asked for help and you're not doing what we're asking you to do. If you don't do what we're asking you to do, you're making it impossible for us to assist you.

    Double check your GPU drivers. Windows 10 has a nasty side effect of rolling back GPU drivers in Creator's Update.

  • My GPU drivers are up to date for sure.

    Sorry, but how do i copy the report from mediainfo?

  • Oh wait, NVM, i figured it out

  • Which file is that from? Input or export? Can you post the other too (and say which is which ;) ) ?

  • that's the exported file. Here's the input file(one of them, because they're shot with the same camera and settings.

    So, that's a completely different file and one that's gone through Handbrake first. First file is 10x larger and 7x longer. Ok, well only obvious difference is the 1440 wide input and the 1920 output. What does the 8 minute long file play like? 

  • oh, I forgot to tell you, that file plays fine, but it's interlaced, that's why its 1440

  • edited October 29

    Interlaced hasn't got anything to do with the width. I have a camera that exports MP4 at 1440 wide and as AVCHD at 1920 wide. Neither are interlaced though. I suspect it's just stretching the 1440 into 1920, just as Hitfilm is when you export this file.

    Plus the MediaInfo for that second, smaller file specifically says Progressive.

    So, if the smaller file works fine and it's the same input format (other than length) as the larger, slower one; then the only thing that comes to mind is: whatever you're using to play back the 10Gb, 58minute file doesn't like playing such a large file. Maybe it tries to buffer it in RAM and you haven't got enough, or is reading through the whole thing to get thumbnails or something.

    One simple test for this is: Cut up the big file into 6 smaller versions, to be closer to the first file and also under 2Gb in length (just to avoid any and all size boundary 'gremlins') and see how those segments play.  If they're fine, then not Hitfilm's fault. Try another player. Or try putting the resulting file back through Handbrake and seeing if that makes it play better.

    Basically, you need to experiment to get a few more data points. Plus, provide a MediaInfo for an original, unHandbraked file to see if it ever really was interlaced. Not that that's a problem, just be useful to know what you're actually using.

  • I have tried just about 25 seconds, same thing. Tried a screen capture, and it's fine with simple things, but things like games Will look laggy in the exported file.

  • So an 8 minute long file plays fine, a 58 minute one is 'laggy' and a 25 second long version of that same file is also 'laggy', but the files both come from the same camera?

    Not interested in the screen capture , as that's just irrelevant to the original complaint. Plus no MediaInfo of the original file. Is it interlaced or not? Who knows? I'm out of ideas, sorry. 

  • All the originals play fine, just when they're rendered, they are "laggy".

    This happened with screen capture as well, but only scenes with more complicated things going on(aka high bit rate parts)

  • Btw, no mediainfo for the footage straight out of the camera because it's a .tod file, and mediainfo isn't taking it. However this shouldn't matter because the one out of handbrake plays fine.

  • OK last thing is: the Handbraked files have a bitrate of 20Mb/s and they're 1440 pixels wide and the Exported versions have a bitrate of 25>30Mb/s and are 1920 pixels wide.

    You say it has problems with detailed areas, which is where the Codec would use the 30Mb/s max  to fit in that detail. So you are potentially pushing 30/20*1920/1440 = 2 times the amount of data at the screen.

    Maybe your machine is struggling with that increase?

    So what's your CPU, GPU, RAM, OS etc. and is it a desktop with a 7200rpm drive, or a laptop with a 5400rpm drive?

    Perhaps try lowering the bitrate and exporting a small section that's causing problems and see if that plays better. Then see how low you can get that's a compromise between quality and speed. Note that if you upload to YouTube it'll get lowered to about 12Mb/s (or is it even 8Mb/s?) anyway, but it is usually better to give it higher quality to work with, so you could also try uploading a 'laggy' version and seeing what it makes of it.

    If that doesn't work, I'm really out of suggestions.

    @Palacono Ok, TOD files. That starts to tell us a few things.

    TOD is a strange wrapper. Basically your camera files are MPEG-2, 1440x1080 with a pixel aspect ratio of 1.33 and interlacing.

    Which at least points to a few things that need to be done at the Handbrake end.

     

  • edited October 30

    @Triem23 He seems to have semi-solved that as he's Handbraked them as Progressive 1440, so Hitfilm must be dealing with the 1.33 aspect ratio on input and so exports as 1920.

    Can he also have Handbrake stretch 1440 to 1920 so Hitfilm does nothing on input?

    Not going to help with his apparent 'laggy' playback on the Exported Hitfilm files though.

  • I'm not sure why, but the aspect ratio is not a problem, the problem is the rendered video looks laggy/choppy, however in the live preview this isn't a problem for some reason.

  • Well, that particular 'some reason' is probably: live preview is showing the clip you imported, which is half the data size of the one you're exporting.

    The other 'some reason' is still guesswork. So, at the risk of repeating myself. Again: What are your machine specs?

  • Also the original footage is one out of a few more shot on the same camera.

  • New drivers came out for my GPU just like 5 minutes ago, i need to retry this.
