It's not the actual framerate causing the problems, it's due to the filesize of the raw recording being too large to be processed correctly. If you want to preview them ahead of time you'll need to encode them so they are small enough to view (and then I would recommend using VLC as it tends to be the smoothest). Is there a reason you can't just preview them in your editing program?

You shouldn't really record at 240 fps imo, 120 is good enough for me and VLC Player works fine for 120 fps footage

It can take a while to open it, import the video and then play it only to just close it again.
How do I process them? I use source recording tool to edit.
And would it be worth it to encode it only to watch it once and then sort it into a folder?

I've tried a 120 fps vid with VLC, didn't work :/

I believe the correct process is something like this. I don't remember the exact commands

1. open the demo file you want to record in tf2
2. change the timescale in console for slow motion
3. record using tf2 build-in stuff, using raw for the tga files at 240 fps or w/e
4. use a tool like virtualdub to compile the tga files and audio file output and render that to a 60fps playable video

Thats how you would render something like this

Anything over what your disk read rate and your ram can process and store is gonna playback choppy. (usually files over a few gbs, depending on length)

So as dellort said you want to encode them first so your computer can playback a smaller file.

Probably the 120fps uncompressed recording is still way too big to playback without stutter.

Alternatively if you wanna play it uncompressed and you have enough ram you can leave it playing in the background and after the first full playback it should play without stutters since it's already "loaded". It might not work in bigger length files tho.

Apart from doing it properly and encoding it you could always just add more SSDs.

I don't watch 240fps vids but mpv does just fine with my 100fps vids

Thanks dave, I'll try it

ive never had any issues watching uncompressed 240 fps clips with any video player with an ssd

MPCHC/CCCP?

What is the bitrate of the video and of your SSD? I would assume you are not trying to play such things on a HD.

Try hardware decoding with some variation of mpc-hc setup.

Use mpc-hc, put it on your ssd, or put it on a ramdisk if you wanna be a true neon cyber warrior

I still don't understand why you need to "preview" them in a video player. You recorded them, you know what's in the clips, right? If you need to sort them, just name them something when you record them (f.e. doubleair_solly_blands_mid, 5k_scout_granary_last)

If you still REALLY want to play them with a video player, then I guess use an SSD, or encode them (they might be choppy even after encoding, I just tried playing a 120fps 720p 84MB enconded clip in VLC and it was watchable, but still slightly choppy, then again I don't have an SSD).

ok, so the bottleneck with raw videos of this size is disk speed (maybe less so with a new superfast PCI-E SSD or whatever they're coming out with now), whether recording the TGAs from tf2 or playing back the uncompressed dubbed video. the media player buffers the file from disk into ram so it can be rendered, but the disk speed is usually too slow, hence the jerky video and choppy audio as it tries to sync them.

you can reduce that by putting it on an SSD. my pro evo 850 can ALMOST cope with uncompressed AVIs but disk space is really short there for anything over a minute or so. MPC-HC and probably some others will store the rendered result in ram meaning (tested up to about 10 seconds) if you sit through the first few seconds it will be butter smooth when you move the cursor thing back and play that part again. this is useful for checking whether stuff recorded well.

if you need smooth realtime previews of your stuff you might be best just encoding the uncompressed files at as high a bitrate as your disk can handle, at the expense of some quality since you're compressing the same video twice basically
