70D choppy/jerky video

HighTower — Wed, 04 Jun 2014 00:19:00 GMT

Hi, recently I got Canon 70D mostly to use it to make videos.

When I watched the videos they were choppy/jerky. I opened it in Windows Media Player, than i downloaded QuickTime and the same problem. I tried open it in Adobe Premiere and exported for YouTube H.264 avi (I always used this for my videos), and It didnt help. Video was still choppy/jerky.

I doubt my computer is too slow:
INTEL I7-3820 3.6 GHZ
KINGSTON HYPER-X 32 GB DDR3/ 1600 MHZ

PNY NVIDIA QUADRO 2000 1GB

I use Windows 7 Proffesional, I tryied QuickTime7 (the newest one on apple website), Adobe Premiere Pro CS 6

Please help

PS. I hope my English is good enough to describe my problem

Its SanDisk Extreme 45MB/s and the card came with the camera.

I doubt it is the camera. I would look else where. Do your recored and playback frame rates match?

I don't do video but I hear my buddies that do talk about framne rates.

@HighTower, What camera settings do you use to record your movies? And nice computer specs. 🙂

If the videos play back properly on the camera itself, then the camera or memory card are not the problem.

It could be something simple like the Video card in your computer.

thanks, I spend a bit on the PC but it was worth it

Rec. specs: 1920 24fps IPB

I though that shutter speed might be the isue but its not.

Preview on the camera is choppy same as on PC

My computer graphic is a preatty killer.

Im going to buy new SD card and give it a try.

If it is choppy on the camera then I would say it is your card. It's probably a counterfeit card and no where near the 45MB/s as advertised.

So, i bought a new SD card 95MB/s sandisc, and the same effect.

I started playing with the camera and with FPS.

I found that the problem is in FPS.

@ 1920 x 1080: 30 fps, 25 fps, 24 fps
@ 1280 x 720: 60 fps, 50 fps
@ 640 x 480: 30 fps, 25 fps

When i record a video in 1280x720 60fps its nice and smooth, any other option is choppy. So now im confuse how people record Full HD 1920x1080 30fps (or less) and its smooth? Why any other camera can record in les then 30fps and its smooth?

For example why this video is smooth and was recorden in 24fps?

I know they used 5D mkiii and some other cameras but still 24fps, action movie plaing nice. My 30fps can record simply card moving on a street.

Do you guys have an idea what is wrong?
thanks

by doing reserch i find that i used wrong word (sorry but dictionary faild), the video is not choppy but stuttering.

I did research for progressive and strobing and i kinda found all the information which is:

If you record in 30fps or less you will have the stuttering effect if obiect are moving. There are few hint how to make it less visible such as lower your shutter speed, or speed the video up a little bit in post production.

I still dont understan why footahe on my GoPro 1080 30fps is nice and smooth even if i record cars, snowboarding etc

Maybe you are using the wrong shutter speed?

Wow! I'd have thought it would be easy to identify your concern but you're right, language opens and closes doors. Glad to hear you worked out the puzzle for us.

BTW I thought your English was excellent.

Huh I wish to speak excellent English... 🙂

Thanks for the link. I'll play with the camera a little bit more, but so far I'm little bit disappointed of the 70D video capabilities.

If the 70D would have 1080 60fps then it would be just perfect.

I had the same problem with my 70D camera. It would run smooth mostly and then jerk every once in a while. What I discovered is that it is not the computer, or the card. It still does it even when the camera is not writing to the card. I found that it is inherent the camera when using anything other than manual mode. The camera needs to adjust the shutter speed and/or the aperture opening to adjust for different light levels and so it will stutter when it needs to shift. When recording video in full manual the video is smooth. The drawback is that it will not adjust to different light levels. This is mainly a problem when shooting indoors or in low light. I'm still trying to see if there is a good compromise.Hope this helps.

FINALLY!!! Your comment was perfect! It's really not the card, because the symptom happens without a card in the camera. Your response totally makes sense! Thanks! Oh...and has their been a firmware update? Or is this part of the design?
