Any ideas of what might be causing this? Sometimes my laptop plays it ok for a few seconds but it will not run smoothly, the file sizes are around 1gb or more. My laptop has 8gb of ram and an i5 4200m cpu. Premiere elements is doing the same as well.
 
I have tried in the film and tv programme on windows 10, quick time and media player, they all seem to do the same. I had nothing else running at the time of playing. I haven't heard of vlc player, will give it a try. Is there a way to check the system resource
 
You can have a look in task manager - see if the hdd is running up at 100% (CTRL+ALT+DEL - task manager, or right click task bar). I find that my win10 laptop would install updates or malware scan at annoying times really. I also find that VLC plays things a lot more smoothly that quicktime, and probably media player.
 
What's the resolution of this video, most computers now will play 1080p but 4K is still borderline for many.
Higher bitrate and frame rate also make it harder to play
 
it seems to be working really hard when trying to burn video to dvd, or trying to just watch the video files. Fan is kicking in and its getting quite hot, but is fine when only running internet.
 
Burning video is majorly resource intensive, the computer generally sucks up all available power no matter how powerful the PC.

Playing video isn't though, you should be able to play 1080 material, have you tried VLC (which is, by far, the best media player for Windows).

edit: what codec is the video recorded in? don't suppose the 7d2 records raw video?

My MacBook stutters a fair amount when I'm using Final Cut Pro; this is only in Full HD mind you, I think because audio tracks are added and it is a considerable length (8minutes on average) it struggles with rendering it and keeping things smooth. It's a MacBook retina with 16GB ram FYI

I may be teaching you to suck eggs :) But try letting FCPX render the file completly before playback . This tends to help reduce "Stuttering" also select optimised media rather than proxy. This helps a lot with quality. I don't normally edit with FCPX on my MBP, but when I have this tends to give more than acceptable quality.

Ah!! Good tip, that's an interesting one I will try that - my impatience has shown itself!
 
do you have a partition ? if yes don't keep any additional softwares installed in c drive..always run it from d or e drive and store your premiere files in d or e ...

c will get chocked after some time with all those files and you need to have some space in c to operate Windows freely.

try clearing the temporary files and install ccleaner and run it. it will clear unwanted files and registries.
 
Have you copied the video file to local disk, or is it playing from memory card?
 
Do you have access to another PC you can try to play the file back on?

Your laptop seems plenty fast enough, could it be a fault with a codec?
 
It does seem strange to me too. I have a lesser spec that plays videos like that fine.

Looking at what the system is doing during video playback might help. Are you playing on battery or plugged in? It's unlikely but you could have done strange power profile set (throttling the laptop for more battery life). More generic troubleshooting might be making sure your driver's are up to date too.
 
Download a program called MediaInfo, it's free, open the file with it, go to tree view, and post that info here please.

Thanks Michael, looking at that info, there doesn't seem anything wrong with the files your camera is producing, so that rules that out, although i'm not a fan of the MOV wrapper used by Canon.

Anyway, so having ruled that out, imo it points firmly at a problem with your laptop.

Did you try playing the file on a different PC?

Yes, i copied it to a usb drive and played it played fine, looking at task during stuttery play it was showing around 1-3mbps and is it played that went up to around 10mbps and then stopped. I also copied the file off the usb back onto my laptop into different folder, that file plays back ok, so I wonder if the file could be corrupt in places, unless there is something else wrong with the laptop I can't find.
 
It could be a failing drive. You can try something like smartmontools to check if the drive is reporting reallocated sectors / pending sectors. Or run a checkdisk.

Tried this today.... You were right! *muppet moment*
 
Also doesn't help playing the file from your "C" drive (assuming your C drive holds the operating system), that means the PC is reading the file AND running the software from the same drive, which will put it under load.

It shouldn't really matter, this is what RAM is for - hard drive loads the program into RAM for instantaneous superfast access and then reads media off the C drive.

Sometimes it will need to go back to C it load some data but it shouldn't affect playback really. I'd be looking at backing up everything important now (before the drive wears any more) and then replacing the HD.

Unfortunately no, the drive would still need to be accessed both ways even with a partition.

If you have an eSATA port, that would be ideal for a second drive, other than that, it would be a USB external drive but then you will likely have the same problems you're having now due to the transfer speed.
