Slow footage playback
on May 5, 2018 at 6:44:33 am

I'm gonna relay all the specs on my computer and the footage and maybe one of you guys can tell me why my comp is struggling to play footage? Everytime I hit the play button it plays the audio but the video just shows a frame every maybe 15 seconds...

So the comp:
Win 7 64bit
16 GB Ram
AMD Athlon II X3 435 Proc 2.9 GHz
500GB harddrive, 80GB free
1 TB external drive the footage is on almost completely free
AMD Radeon 6500 1 GB RAM

footage is 60fps(actually 41 fps) 1920x1080 about an hour of footage

Some of the clips have the yellow render bar, some are green, the yellow is the most unplayable.

Any ideas why I cant edit normally?

Premiere 2015 cannot handle variable framerate footage.
Need to convert with Handbrake to constant frame rate first.

I've done that already. Actually Variable framerate footage plays, it just doesnt have the audio synced up properly. The weird thing is Ive done videos already and Im following the same exact process, they would playback slow sometime before the more effects and things I added, this is the first time just starting a rough cut has locked it up like this ☹ Its impossible to edit with it doing this, I am completely confused. Also when I look at the clip properties, some that are ten minutes are 2 GB, some that are 5 minutes are 5GB, all shot at the same time with the same settings, it doesnt make any sense

Well, it's obvious the two clips in your example are NOT the same. We know little about this footage, so we can only guess.. and that isn't good.

Here are some things you can try: 1, check your source clip information by locating it in your project folder>right click>modify>interpret footage, this will show you exactly what frame rate your source footage is set to and you can change it if you need to or leave it alone. 2, you can lower the quality of video playback to use less processing power by selecting an option from the drop down tab on the program monitor.

Download Mediainfo and check the framerate and framerate mode.
Then you know if can interprete the footage or need to convert.

the frame rate is 41.17, and I lowered it to 1/8 which is as low as it would go, I always edit with it as low as I can to optimize response times

Some questions yet....

1. What is your external drive connected with?
2. Is your footage 60 / 41 / or variable frame rate?
3. Where did this footage originate?
4. Any other info about the file? Container (mov/mp4/mxf) or Codec (h264/Animation/ProRes)

This will go a long way in helping you out.

ext drive connected with usb cable
footage was converted from 60fps to 41.17 after changing it to constant frame rate in handbrake
footage was recorded on a galaxy s7
the files are mpeg4, one of them converted to mp4, not sure why the difference but I did note that.

I assumed that the change to 41 was to synce the video with the audio because the audio track was shorter or something, not exactly sure what that conversion from variable to constant actually does.

Convert to a decent editing codec. Like DNxHD.
Is it USB 3? Not a RAID, I suppose. And a GPU with 1 GB RAM?!!!! Not good at all.
If you're making money out of it, get a decent Thunderbolt RAID, transcode the footage to a good editing codec and upgrade your GPU to something with 4 GB RAM.
I've always been on a Mac. I would use MPEG Streamclip (free) to transcode to ProRes 422 LT (or ProRes 422) and edit the converted files off a 4 bay Thunderbolt RAID.
